[Security Considerations](#security-considerations) + +--- + +## Overview + +This document describes the architecture for implementing a flexible, scalable role-based access control (RBAC) system for the Mila membership management application. The system provides: + +- **Predefined Permission Sets** with configurable permissions +- **Dynamic Roles** that reference permission sets +- **Resource-level and Action-level** authorization +- **Page-level** access control for LiveView routes +- **Special handling** for credentials and linked user-member relationships +- **Future extensibility** for field-level permissions + +### Key Design Principles + +1. **Separation of Concerns:** Permission Sets (what you can do) vs. Roles (job titles/functions) +2. **Flexibility:** Admins can configure permissions at runtime via database +3. **Performance:** Leverage Ash Framework policies with ETS caching +4. **Extensibility:** Architecture supports future field-level granularity +5. **Consistency:** Single unified permission model for all resources + +--- + +## Requirements Analysis + +### Core Requirements + +Based on the project requirements, the system must support: + +#### Permission Sets (4 Predefined) + +1. **Own Data** - Users can only access their own data +2. **Read-Only** - Read access to all members, groups, and custom fields +3. **Normal User** - Read and write access to members and custom fields +4. **Admin** - Full access to all resources including user management + +#### Example Roles + +- **Mitglied** (Member) - Default role, own data access +- **Vorstand** (Board) - Access to members, not users +- **Kassenwart** (Treasurer) - Access to payment information +- **Buchhaltung** (Accounting) - Read-only access +- **Admin** - Full administrative access + +#### Authorization Granularity + +**Resource Level (Phase 1 - Now):** +- Member: read, create, update, destroy +- User: read, create, update, destroy +- PropertyType: read, create, update, destroy +- Property: read, create, update, destroy +- Role: read, create, update, destroy +- Payment (future): read, create, update, destroy + +**Page Level:** +- Control access to LiveView pages +- Pages are read-only access checks +- Edit pages require both page access AND resource write permission + +**Field Level (Phase 2 - Later):** +- Restrict read/write access to specific member fields +- Restrict access to specific custom field types +- Example: Treasurer sees payment_history, Board does not + +#### Special Cases + +1. **User Credentials:** + - Users can ALWAYS edit their own credentials (email, password) + - Only Admins can edit OTHER users' credentials + - Email field of members linked to users can only be edited by Admins + +2. **Required Fields:** + - When creating a member with required custom fields, user must be able to write those fields + - Even if user normally doesn't have write permission for that field type + - After creation, normal permissions apply + +3. **Payment History (Future):** + - Configurable per permission set + - Members may or may not see their own payment history + +4. **Linked User-Member Relationships:** + - Member email sync follows special rules + - User email is source of truth for linked members + +#### Constraints + +- Roles can be added, renamed, or removed by admins +- Permission sets are predefined but permissions are configurable +- Each user has exactly ONE role +- Roles cannot overlap (no multiple role assignment per user) +- "Mitglied" role is a system role and cannot be deleted +- Permission sets are system-defined and cannot be deleted + +--- + +## Evaluated Approaches + +We evaluated four different architectural approaches for implementing the authorization system: + +### Approach 1: Ash Policies + RBAC with JSONB Permissions + +**Description:** Store permissions as JSONB in the Role resource, use custom Ash Policy checks to evaluate them. + +**Database Structure:** +``` +roles (id, name, permissions_config: jsonb) +users (role_id) +``` + +**Permissions stored as:** +```json +{ + "resource_permissions": { + "Member": {"read": true, "update": false} + }, + "page_permissions": { + "/members": true + } +} +``` + +**Advantages:** +- ✅ Simple database schema (fewer tables) +- ✅ Flexible JSON structure +- ✅ Fast schema changes (no migrations needed) +- ✅ Easy to serialize/deserialize + +**Disadvantages:** +- ❌ No referential integrity on permission keys +- ❌ JSONB queries are less efficient than normalized tables +- ❌ Difficult to query "which roles have access to X?" +- ❌ Schema validation happens in application code +- ❌ No indexing on individual permissions +- ❌ Versioning of JSONB structure becomes complex + +**Verdict:** ❌ Not selected - JSONB makes querying and validation difficult + +--- + +### Approach 2: Hybrid RBAC + ABAC with Permission Matrix + +**Description:** Separate tables for every permission type with full granularity from day one. + +**Database Structure:** +``` +roles (id, name) +permissions (id, resource, action, field, condition) +role_permissions (role_id, permission_id, granted) +user_roles (user_id, role_id) +``` + +**Advantages:** +- ✅ Maximum flexibility +- ✅ Highly granular from the start +- ✅ Easy to add new permission types +- ✅ Audit trail built-in + +**Disadvantages:** +- ❌ Very complex database schema +- ❌ High JOIN overhead on every authorization check +- ❌ Over-engineered for current requirements +- ❌ Difficult to cache effectively +- ❌ Performance concerns with many permissions +- ❌ Complex to seed and maintain + +**Verdict:** ❌ Not selected - Too complex for current needs, over-engineering + +--- + +### Approach 3: Policy Graphs with Custom Authorizer + +**Description:** Use Ash Policies for action-level checks, custom Authorizer module for field-level filtering. + +**Database Structure:** +``` +roles (id, name, permission_config) +Custom Authorizer reads config and applies filters +``` + +**Advantages:** +- ✅ Best performance (optimized for Ash) +- ✅ Granular field-level control +- ✅ Can leverage Ash query optimization + +**Disadvantages:** +- ❌ Requires custom authorizer implementation (non-standard) +- ❌ More code to maintain +- ❌ Harder to test than declarative policies +- ❌ Mixes declarative (Policies) and imperative (Authorizer) approaches + +**Verdict:** ❌ Not selected - Too much custom code, reduces maintainability + +--- + +### Approach 4: Simple Role Enum (Quick Start) + +**Description:** Simple `:role` field on User with enum values, policies hardcoded in resources. + +**Database Structure:** +``` +users (role: :admin | :vorstand | :kassenwart | :member) +``` + +**Advantages:** +- ✅ Very simple to implement (1 week) +- ✅ No extra tables needed +- ✅ Fast performance +- ✅ Easy to understand + +**Disadvantages:** +- ❌ No dynamic permission configuration +- ❌ Requires code deployment to change permissions +- ❌ Can't add new roles without code changes +- ❌ Not extensible to field-level permissions +- ❌ Doesn't meet requirement for "configurable permissions" + +**Verdict:** ❌ Not selected - Doesn't meet core requirements + +--- + +## Selected Architecture + +### Approach 5: Permission Sets + Normalized Tables (Selected) + +**Description:** Hybrid approach that separates Permission Sets (what you can do) from Roles (who you are), with normalized database tables for queryability and Ash Policies for enforcement. + +**Key Innovation:** Introduce **Permission Sets** as an abstraction layer between Roles and actual Permissions. + +``` +Permission Set (4 predefined, defines capabilities) + ↓ +Role (many, references one Permission Set) + ↓ +User (each has one Role) +``` + +**Why This Approach?** + +1. **Meets Requirements:** + - ✅ Configurable permissions (stored in database) + - ✅ Dynamic role creation + - ✅ Extensible to field-level + - ✅ Admin UI can modify at runtime + +2. **Performance:** + - ✅ Normalized tables allow efficient queries + - ✅ Indexes on resource_name and action + - ✅ ETS cache for permission lookups + - ✅ Ash Policies translate to SQL filters + +3. **Maintainability:** + - ✅ Clear separation of concerns + - ✅ Standard Ash patterns (not custom authorizer) + - ✅ Testable with standard Ash policy tests + - ✅ Easy to understand and debug + +4. **Extensibility:** + - ✅ `field_name` column reserved for Phase 2 + - ✅ `scope` system handles "own" vs "all" vs "linked" + - ✅ New resources just add permission rows + - ✅ No code changes needed for new roles + +5. **Flexibility:** + - ✅ Permission Sets ensure consistency + - ✅ Roles can be renamed without changing permissions + - ✅ Multiple roles can share same permission set + - ✅ Admin can configure at runtime + +**Trade-offs Accepted:** +- More tables than JSONB approach (but better queryability) +- More rows than enum approach (but runtime configurable) +- Not as granular as full ABAC (but simpler to manage) + +--- + +## Database Schema + +### Entity Relationship Diagram + +``` +┌─────────────────────┐ +│ permission_sets │ +│─────────────────────│ +│ id (PK) │ +│ name │◄───────┐ +│ description │ │ +│ is_system │ │ +└─────────────────────┘ │ + │ + │ +┌─────────────────────────────┐│ +│ permission_set_resources ││ +│─────────────────────────────││ +│ id (PK) ││ +│ permission_set_id (FK) │┘ +│ resource_name │ +│ action │ +│ scope │ +│ field_name (nullable) │ +│ granted │ +└─────────────────────────────┘ + +┌─────────────────────────────┐ +│ permission_set_pages │ +│─────────────────────────────│ +│ id (PK) │ +│ permission_set_id (FK) │───┐ +│ page_path │ │ +└─────────────────────────────┘ │ + │ + │ +┌─────────────────────┐ │ +│ roles │ │ +│─────────────────────│ │ +│ id (PK) │ │ +│ name │ │ +│ description │ │ +│ permission_set_id │──────────┘ +│ is_system_role │ +└─────────────────────┘ + ▲ + │ + │ +┌─────────────────────┐ +│ users │ +│─────────────────────│ +│ id (PK) │ +│ email │ +│ hashed_password │ +│ oidc_id │ +│ member_id (FK) │ +│ role_id (FK) │◄──── Default: "Mitglied" role +└─────────────────────┘ +``` + +### Table Definitions + +#### `permission_sets` + +Defines the 4 core permission sets.

Privilege Escalation + +**Threat:** User tries to escalate privileges by manipulating requests. + +**Mitigation:** +- All authorization enforced server-side (Ash Policies) +- Actor is verified via session +- No client-side permission checks that can be bypassed +- Cache invalidation ensures stale permissions aren't used + +#### 2. Permission Cache Poisoning + +**Threat:** Attacker manipulates ETS cache to grant unauthorized access. + +**Mitigation:** +- ETS table is server-side only +- Cache keys include user_id (can't access other users' cache) +- Cache invalidated on any permission change +- Fallback to database if cache returns unexpected data + +#### 3. SQL Injection via Scope Filters + +**Threat:** Malicious actor value causes SQL injection in scope filters. + +**Mitigation:** +- All filters use Ash's expr() macro with parameterized queries +- Actor ID is always a UUID (validated by database) +- No string concatenation in filter construction + +#### 4. Permission Set Modification + +**Threat:** Unauthorized user modifies permission sets or roles. + +**Mitigation:** +- Permission Sets have `is_system = true` and cannot be deleted +- Role management requires Admin permission +- Audit log (future) tracks all permission changes + +#### 5. Bypass via Direct Database Access + +**Threat:** Code bypasses Ash and queries database directly. + +**Mitigation:** +- Code review enforces "always use Ash" policy +- No raw SQL in application code +- Database credentials secured via environment variables + +#### 6. Session Hijacking + +**Threat:** Attacker steals session and impersonates user. + +**Mitigation:** +- Handled by AshAuthentication (out of scope for this document) +- Sessions use signed tokens +- HTTPS in production + +--- + +### Audit Logging (Future) + +For compliance and debugging, implement audit log: + +```sql +CREATE TABLE permission_audit_log ( + id UUID PRIMARY KEY DEFAULT gen_random_uuid(), + user_id UUID REFERENCES users(id), + action VARCHAR(50), -- "role_changed", "permission_modified" + resource_type VARCHAR(255), + resource_id UUID, + old_value JSONB, + new_value JSONB, + timestamp TIMESTAMP NOT NULL DEFAULT now() +); +``` + +--- + +## Appendix + +### Glossary + +- **Permission Set:** A predefined collection of permissions defining what actions can be performed +- **Role:** A named job function (e.g., "Treasurer") that references one permission set +- **Resource:** An Ash resource (e.g., Member, User, PropertyType) +- **Action:** An Ash action (e.g., read, create, update, destroy) +- **Scope:** The subset of records a permission applies to (own, linked, all) +- **Actor:** The current user making a request +- **Page Permission:** Access control for LiveView routes +- **Field-Level Permission:** Restriction on specific fields of a resource (Phase 2) + +### Permission Set Summary + +| Permission Set | Use Case | Example Roles | Resources Access | +|---------------|----------|---------------|------------------| +| **own_data** | Users accessing only their own data | Mitglied | User (own), Member (linked), Property (linked) | +| **read_only** | Users who can view but not edit | Vorstand, Buchhaltung | Member (all, read), Property (all, read) | +| **normal_user** | Users who can edit members and properties | Kassenwart | Member (all, read/write), Property (all, read/write) | +| **admin** | Full administrative access | Admin | All resources (all, full CRUD) | + +### Resource Permission Matrix + +| Resource | Own Data | Read-Only | Normal User | Admin | +|----------|----------|-----------|-------------|-------| +| **Member** | Linked: R/W | All: R | All: R/W | All: Full | +| **User** | Own: R/W | None | None | All: Full | +| **PropertyType** | All: R | All: R | All: R | All: Full | +| **Property** | Linked: R/W | All: R | All: R/W | All: Full | +| **Role** | None | All: R | None | All: Full | +| **Payment** (future) | Linked: R (config) | None | All: R/W | All: Full | + +### Page Permission Matrix + +| Page Path | Own Data | Read-Only | Normal User | Admin | +|-----------|----------|-----------|-------------|-------| +| `/profile` | ✅ | ✅ | ✅ | ✅ | +| `/members` | ❌ | ✅ | ✅ | ✅ | +| `/members/:id` | ❌ | ✅ | ✅ | ✅ | +| `/members/new` | ❌ | ❌ | ✅ | ✅ | +| `/members/:id/edit` | ❌ | ❌ | ✅ | ✅ | +| `/users` | ❌ | ❌ | ❌ | ✅ | +| `/users/:id/edit` | ❌ | ❌ | ❌ | ✅ | +| `/property-types` | ❌ | ✅ | ✅ | ✅ | +| `/property-types/new` | ❌ | ❌ | ❌ | ✅ | +| `/admin` | ❌ | ❌ | ❌ | ✅ | + +--- + +## Document History + +| Version | Date | Author | Changes | +|---------|------|--------|---------| +| 1.0 | 2025-11-10 | Architecture Team | Initial architecture design | + +--- + +**End of Document** + diff --git a/docs/roles-and-permissions-implementation-plan.md b/docs/roles-and-permissions-implementation-plan.md new file mode 100644 index 0000000..92bd262 --- /dev/null +++ b/docs/roles-and-permissions-implementation-plan.md @@ -0,0 +1,2368 @@ +# Roles and Permissions - Implementation Plan + +**Project:** Mila - Membership Management System +**Feature:** Role-Based Access Control (RBAC) Implementation +**Version:** 1.0 +**Last Updated:** 2025-11-10 +**Status:** Ready for Implementation + +--- + +## Table of Contents + +1.

Predefined Permission Sets** -#### Permission Sets (4 Predefined) +Four hardcoded permission sets that define access patterns: -1. **Own Data** - Users can only access their own data -2. **Read-Only** - Read access to all members, groups, and custom fields -3. **Normal User** - Read and write access to members and custom fields -4. **Admin** - Full access to all resources including user management +- **own_data** - User can only access their own data (default for members) +- **read_only** - Read access to all member data, no modifications +- **normal_user** - Create/Read/Update on members (no delete), full CRUD on custom fields +- **admin** - Unrestricted access including user/role management -#### Example Roles +**2. Roles Stored in Database** -- **Mitglied** (Member) - Default role, own data access -- **Vorstand** (Board) - Access to members, not users -- **Kassenwart** (Treasurer) - Access to payment information -- **Buchhaltung** (Accounting) - Read-only access -- **Admin** - Full administrative access +Five predefined roles stored in the `roles` table: -#### Authorization Granularity +- **Mitglied** (Member) → uses "own_data" permission set +- **Vorstand** (Board) → uses "read_only" permission set +- **Kassenwart** (Treasurer) → uses "normal_user" permission set +- **Buchhaltung** (Accounting) → uses "read_only" permission set +- **Admin** → uses "admin" permission set -**Resource Level (Phase 1 - Now):** -- Member: read, create, update, destroy -- User: read, create, update, destroy -- PropertyType: read, create, update, destroy -- Property: read, create, update, destroy -- Role: read, create, update, destroy -- Payment (future): read, create, update, destroy +**3. Resource-Level Permissions** -**Page Level:** -- Control access to LiveView pages -- Pages are read-only access checks -- Edit pages require both page access AND resource write permission +Control CRUD operations on: +- User (credentials, profile) +- Member (member data) +- Property (custom field values) +- PropertyType (custom field definitions) +- Role (role management) -**Field Level (Phase 2 - Later):** -- Restrict read/write access to specific member fields -- Restrict access to specific custom field types -- Example: Treasurer sees payment_history, Board does not +**4. Page-Level Permissions** -#### Special Cases +Control access to LiveView pages: +- Index pages (list views) +- Show pages (detail views) +- Form pages (create/edit) +- Admin pages -1. **User Credentials:** - - Users can ALWAYS edit their own credentials (email, password) - - Only Admins can edit OTHER users' credentials - - Email field of members linked to users can only be edited by Admins +**5. Granular Scopes** -2. **Required Fields:** - - When creating a member with required custom fields, user must be able to write those fields - - Even if user normally doesn't have write permission for that field type - - After creation, normal permissions apply +Three scope levels for permissions: +- **:own** - Only records where `record.id == user.id` (for User resource) +- **:linked** - Only records linked to user via relationships + - Member: `member.user_id == user.id` + - Property: `property.member.user_id == user.id` +- **:all** - All records, no filtering -3. **Payment History (Future):** - - Configurable per permission set - - Members may or may not see their own payment history +**6. Special Cases** -4. **Linked User-Member Relationships:** - - Member email sync follows special rules - - User email is source of truth for linked members +- **Own Credentials:** Every user can always read/update their own credentials +- **Linked Member Email:** Only admins can edit email of member linked to user +- **System Roles:** "Mitglied" role cannot be deleted (is_system_role flag) +- **User-Member Linking:** Only admins can link/unlink users and members -#### Constraints +**7. UI Consistency** -- Roles can be added, renamed, or removed by admins -- Permission sets are predefined but permissions are configurable -- Each user has exactly ONE role -- Roles cannot overlap (no multiple role assignment per user) -- "Mitglied" role is a system role and cannot be deleted -- Permission sets are system-defined and cannot be deleted - ---- - -## Evaluated Approaches - -We evaluated four different architectural approaches for implementing the authorization system: - -### Approach 1: Ash Policies + RBAC with JSONB Permissions - -**Description:** Store permissions as JSONB in the Role resource, use custom Ash Policy checks to evaluate them. - -**Database Structure:** -``` -roles (id, name, permissions_config: jsonb) -users (role_id) -``` - -**Permissions stored as:** -```json -{ - "resource_permissions": { - "Member": {"read": true, "update": false} - }, - "page_permissions": { - "/members": true - } -} -``` - -**Advantages:** -- ✅ Simple database schema (fewer tables) -- ✅ Flexible JSON structure -- ✅ Fast schema changes (no migrations needed) -- ✅ Easy to serialize/deserialize - -**Disadvantages:** -- ❌ No referential integrity on permission keys -- ❌ JSONB queries are less efficient than normalized tables -- ❌ Difficult to query "which roles have access to X?" -- ❌ Schema validation happens in application code -- ❌ No indexing on individual permissions -- ❌ Versioning of JSONB structure becomes complex - -**Verdict:** ❌ Not selected - JSONB makes querying and validation difficult - ---- - -### Approach 2: Hybrid RBAC + ABAC with Permission Matrix - -**Description:** Separate tables for every permission type with full granularity from day one. - -**Database Structure:** -``` -roles (id, name) -permissions (id, resource, action, field, condition) -role_permissions (role_id, permission_id, granted) -user_roles (user_id, role_id) -``` - -**Advantages:** -- ✅ Maximum flexibility -- ✅ Highly granular from the start -- ✅ Easy to add new permission types -- ✅ Audit trail built-in - -**Disadvantages:** -- ❌ Very complex database schema -- ❌ High JOIN overhead on every authorization check -- ❌ Over-engineered for current requirements -- ❌ Difficult to cache effectively -- ❌ Performance concerns with many permissions -- ❌ Complex to seed and maintain - -**Verdict:** ❌ Not selected - Too complex for current needs, over-engineering - ---- - -### Approach 3: Policy Graphs with Custom Authorizer - -**Description:** Use Ash Policies for action-level checks, custom Authorizer module for field-level filtering. - -**Database Structure:** -``` -roles (id, name, permission_config) -Custom Authorizer reads config and applies filters -``` - -**Advantages:** -- ✅ Best performance (optimized for Ash) -- ✅ Granular field-level control -- ✅ Can leverage Ash query optimization - -**Disadvantages:** -- ❌ Requires custom authorizer implementation (non-standard) -- ❌ More code to maintain -- ❌ Harder to test than declarative policies -- ❌ Mixes declarative (Policies) and imperative (Authorizer) approaches - -**Verdict:** ❌ Not selected - Too much custom code, reduces maintainability - ---- - -### Approach 4: Simple Role Enum (Quick Start) - -**Description:** Simple `:role` field on User with enum values, policies hardcoded in resources. - -**Database Structure:** -``` -users (role: :admin | :vorstand | :kassenwart | :member) -``` - -**Advantages:** -- ✅ Very simple to implement (1 week) -- ✅ No extra tables needed -- ✅ Fast performance -- ✅ Easy to understand - -**Disadvantages:** -- ❌ No dynamic permission configuration -- ❌ Requires code deployment to change permissions -- ❌ Can't add new roles without code changes -- ❌ Not extensible to field-level permissions -- ❌ Doesn't meet requirement for "configurable permissions" - -**Verdict:** ❌ Not selected - Doesn't meet core requirements +- UI elements (buttons, links) only shown if user has permission +- Page access controlled before LiveView mounts +- Consistent authorization logic between backend and frontend --- ## Selected Architecture -### Approach 5: Permission Sets + Normalized Tables (Selected) +### Approach: Hardcoded Permission Sets with Database Roles -**Description:** Hybrid approach that separates Permission Sets (what you can do) from Roles (who you are), with normalized database tables for queryability and Ash Policies for enforcement. - -**Key Innovation:** Introduce **Permission Sets** as an abstraction layer between Roles and actual Permissions. +**Core Concept:** ``` -Permission Set (4 predefined, defines capabilities) - ↓ -Role (many, references one Permission Set) - ↓ -User (each has one Role) +PermissionSets Module (hardcoded in code) + ↓ (referenced by permission_set_name) +Role (stored in DB: "Vorstand" → "read_only") + ↓ (assigned to user via role_id) +User (each user has one role) ``` **Why This Approach?** -1. **Meets Requirements:** - - ✅ Configurable permissions (stored in database) - - ✅ Dynamic role creation - - ✅ Extensible to field-level - - ✅ Admin UI can modify at runtime +✅ **Fast Implementation:** 2-3 weeks vs. 4-5 weeks for DB-backed +✅ **Maximum Performance:** < 1 microsecond per check (pure function call) +✅ **Zero DB Overhead:** No permission queries, no joins, no cache needed +✅ **Git-Tracked Changes:** All permission changes in version control +✅ **Deterministic Testing:** No DB setup, purely functional tests +✅ **Clear Migration Path:** Well-defined Phase 3 for DB-backed permissions -2. **Performance:** - - ✅ Normalized tables allow efficient queries - - ✅ Indexes on resource_name and action - - ✅ ETS cache for permission lookups - - ✅ Ash Policies translate to SQL filters +**Trade-offs:** -3. **Maintainability:** - - ✅ Clear separation of concerns - - ✅ Standard Ash patterns (not custom authorizer) - - ✅ Testable with standard Ash policy tests - - ✅ Easy to understand and debug +⚠️ **Deployment Required:** Permission changes need code deployment +⚠️ **Four Fixed Sets:** Cannot add new permission sets without code change +✔️ **Acceptable for MVP:** Requirements specify 4 fixed sets, rare changes expected -4. **Extensibility:** - - ✅ `field_name` column reserved for Phase 2 - - ✅ `scope` system handles "own" vs "all" vs "linked" - - ✅ New resources just add permission rows - - ✅ No code changes needed for new roles +### System Architecture Diagram -5. **Flexibility:** - - ✅ Permission Sets ensure consistency - - ✅ Roles can be renamed without changing permissions - - ✅ Multiple roles can share same permission set - - ✅ Admin can configure at runtime +``` +┌─────────────────────────────────────────────────────────────┐ +│ Authorization System │ +└─────────────────────────────────────────────────────────────┘ -**Trade-offs Accepted:** -- More tables than JSONB approach (but better queryability) -- More rows than enum approach (but runtime configurable) -- Not as granular as full ABAC (but simpler to manage) +┌──────────────────┐ +│ LiveView │ +│ (UI Layer) │ +└────────┬─────────┘ + │ + │ 1.

- # Then check scope for each member (if needed) - members_with_permissions = - Enum.map(members, fn member -> - %{ - member: member, - can_update: can_update_any && can_update_this?(current_user, member), - can_destroy: can_destroy_any && can_destroy_this?(current_user, member) - } - end) - - {:ok, - socket - |> assign(:members_with_permissions, members_with_permissions) - |> assign(:can_create, can?(current_user, :create, Mv.Membership.Member))} -end -``` -

-**Timeline:** Sprint 4-5 (after Phase 1 is stable) - -**Goal:** Allow permission sets to restrict access to specific fields of resources. - -#### Database Schema (Already Prepared) - -The `permission_set_resources.field_name` column is already in place: -- `NULL` = all fields (Phase 1 default) -- `"field_name"` = specific field (Phase 2) - -#### Implementation Approach - -**Option A: Blacklist Approach (Recommended)** - -Permission with `field_name = NULL` grants access to all fields. Additional rows with `granted = false` deny specific fields. - -```sql --- Normal User can read all Member fields -INSERT INTO permission_set_resources - (permission_set_id, resource_name, action, field_name, granted) -VALUES - (normal_user_id, 'Member', 'read', NULL, true); - --- But NOT birth_date -INSERT INTO permission_set_resources - (permission_set_id, resource_name, action, field_name, granted) -VALUES - (normal_user_id, 'Member', 'read', 'birth_date', false); - --- And NOT notes -INSERT INTO permission_set_resources - (permission_set_id, resource_name, action, field_name, granted) -VALUES - (normal_user_id, 'Member', 'read', 'notes', false); -``` - -**Evaluation Logic:** -1. Check if there's a permission with `field_name = NULL` and `granted = true` -2. If yes: Load all deny entries (`field_name != NULL` and `granted = false`) -3. Deselect those fields from query - -**Advantages:** -- Default is "allow all fields" -- Only need to specify exceptions -- Easy to add new fields (automatically included) - -**Disadvantages:** -- Can't have different scopes per field (all fields have same scope) - ---- - -**Option B: Whitelist Approach** - -No permission with `field_name = NULL`. Only explicit `granted = true` entries allow access. - -```sql --- Read-Only can ONLY read these specific Member fields -INSERT INTO permission_set_resources - (permission_set_id, resource_name, action, field_name, granted) -VALUES - (read_only_id, 'Member', 'read', 'first_name', true), - (read_only_id, 'Member', 'read', 'last_name', true), - (read_only_id, 'Member', 'read', 'email', true), - (read_only_id, 'Member', 'read', 'phone_number', true); --- birth_date, notes, etc. are implicitly denied -``` - -**Evaluation Logic:** -1. Check if there's a permission with `field_name = NULL` and `granted = true` -2. If no: Load all allow entries (`field_name != NULL` and `granted = true`) -3. Only select those fields in query - -**Advantages:** -- Explicit "allow" model (more secure default) -- Could have different scopes per field (future feature) - -**Disadvantages:** -- Tedious to specify every allowed field -- New fields are denied by default (requires permission update) - ---- - -#### Custom Preparation for Field Filtering - -```elixir -defmodule Mv.Authorization.Preparations.FilterFieldsByPermission do - use Ash.Resource.Preparation - - def prepare(query, _opts, context) do - actor = context.actor - action = query.action - resource = query.resource - - # Get denied fields for this actor/resource/action - denied_fields = get_denied_fields(actor, resource, action.name) - - # Deselect denied fields - Ash.Query.deselect(query, denied_fields) - end - - defp get_denied_fields(actor, resource, action) do - permission_set = get_permission_set(actor) - resource_name = resource |> Module.split() |> List.last() - - # Query denied fields (blacklist approach) - Mv.Authorization.PermissionSetResource - |> Ash.Query.filter( - permission_set_id == ^permission_set.id and - resource_name == ^resource_name and - action == ^action and - not is_nil(field_name) and - granted == false - ) - |> Ash.read!() - |> Enum.map(& &1.field_name) - |> Enum.map(&String.to_existing_atom/1) - end -end - -# Add to resources in Phase 2 -defmodule Mv.Membership.Member do - preparations do - prepare Mv.Authorization.Preparations.FilterFieldsByPermission - end -end -``` - ---- - -#### Custom Fields (Properties) Field-Level - -For custom fields, field-level permissions work differently: - -**Approach:** `field_name` stores the PropertyType name (not Property field) - -```sql --- Read-Only can ONLY see "membership_number" custom field -INSERT INTO permission_set_resources - (permission_set_id, resource_name, action, field_name, granted) -VALUES - (read_only_id, 'Property', 'read', 'membership_number', true); - --- All other PropertyTypes are denied -``` +**Requirement:** Every user can ALWAYS read and update their own credentials (email, password), regardless of their role. **Implementation:** +Policy in `User` resource places this check BEFORE the general `HasPermission` check: + ```elixir -defmodule Mv.Authorization.Preparations.FilterPropertiesByType do - use Ash.Resource.Preparation +policies do + # SPECIAL CASE: Takes precedence over role permissions + policy action_type([:read, :update]) do + description "Users can always read and update their own account" + authorize_if expr(id == ^actor(:id)) + end - def prepare(query, _opts, context) do - actor = context.actor + # GENERAL: For other operations (e.g., admin reading other users) + policy action_type([:read, :create, :update, :destroy]) do + authorize_if Mv.Authorization.Checks.HasPermission + end +end +``` + +**Why this works:** +- Ash evaluates policies top-to-bottom +- First matching policy wins +- Special case catches own-account access before checking permissions +- Even a user with `own_data` (no admin permissions) can update their credentials + +### 2.

The implementation is broken down into **18 small, focused issues** that can be worked on in parallel where possible. +### Overview -**Key Principles:** -- **Test-Driven Development (TDD):** Write tests first, then implement -- **Small, Focused Issues:** Each issue is 1-4 days of work -- **Parallelization:** Multiple issues can be worked on simultaneously -- **Clear Dependencies:** Dependency graph shows what must be completed first -- **Definition of Done:** Each issue has clear completion criteria +This document defines the implementation plan for the **MVP (Phase 1)** of the Roles and Permissions system using **hardcoded Permission Sets** in an Elixir module. -**Related Documents:** -- [Architecture Design](./roles-and-permissions-architecture.md) - Complete system architecture and design decisions +**Key Characteristics:** +- **15 issues total** (Issues #1-3, #6-17) +- **2-3 weeks duration** +- **180+ tests** +- **Test-Driven Development (TDD)** throughout +- **No database tables for permissions** - only `roles` table +- **Zero performance concerns** - all permission checks are in-memory function calls + +### What's NOT in MVP + +**Deferred to Phase 3 (Future):** +- Issue #4: `PermissionSetResource` database table +- Issue #5: `PermissionSetPage` database table +- Issue #18: ETS Permission Cache +- Database-backed dynamic permissions + +### The Four Permission Sets + +Hardcoded in `Mv.Authorization.PermissionSets` module: + +1. **own_data** - User can only access their own data (default for "Mitglied") +2. **read_only** - Read access to all members/properties (for "Vorstand", "Buchhaltung") +3. **normal_user** - Create/Read/Update members (no delete), full CRUD on properties (for "Kassenwart") +4. **admin** -

Write Failing Tests First:** - - For each issue, write tests that define expected behavior - - Tests should fail because functionality doesn't exist yet - - Tests serve as specification and documentation +**Benefits of Hardcoded Approach:** +- **Speed:** 2-3 weeks vs. 4-5 weeks for DB-backed +- **Performance:** < 1 microsecond per check (pure function call) +- **Simplicity:** No cache, no DB queries, easy to reason about +- **Version Control:** All permission changes tracked in Git +- **Testing:** Deterministic, no DB setup needed -2. **Green Phase - Implement Minimum Code:** - - Write just enough code to make tests pass - - Focus on functionality, not perfection - - Get to green as quickly as possible - -3. **Refactor Phase - Clean Up:** - - Clean up code while keeping tests green - - Improve structure, naming, and organization - - Ensure code follows guidelines - -4. **Integration Phase - Ensure Components Work Together:** - - Write integration tests - - Test cross-component interactions - - Verify complete user flows - -### Test Coverage Goals - -| Test Type | Coverage Goal | Description | -|-----------|---------------|-------------| -| **Unit Tests** | >90% | Policy checks, permission evaluation, cache operations | -| **Integration Tests** | >80% | Cross-resource authorization, special cases | -| **LiveView Tests** | >85% | Page permission enforcement, UI interactions | -| **E2E Tests** | 100% of user flows | Complete journeys for each role | -

[Related Documents](#related-documents) + +--- + +## Overview + +The Mila membership management system requires a flexible authorization system that controls: +- **Who** can access **what** resources +- **Which** pages users can view +- **How** users interact with their own vs. others' data + +### Key Design Principles + +1. **Simplicity First:** Start with hardcoded permissions for fast MVP delivery +2. **Performance:** No database queries for permission checks in MVP +3. **Clear Migration Path:** Easy upgrade to database-backed permissions when needed +4. **Security:** Explicit action-based authorization with no ambiguity +5. **Maintainability:** Permission logic reviewable in Git, testable as pure functions + +### Core Concepts + +**Permission Set:** Defines a collection of permissions (e.g., "read_only", "admin") + +**Role:** A named job function that references one Permission Set (e.g., "Vorstand" uses "read_only") + +**User:** Each user has exactly one Role, inheriting that Role's Permission Set + +**Scope:** Defines the breadth of access - "own" (only own data), "linked" (data connected to user), "all" (everything) + +--- + +## Evaluated Approaches + +During the design phase, we evaluated multiple implementation approaches to find the optimal balance between simplicity, performance, and future extensibility. + +### Approach 1: JSONB in Roles Table + +Store all permissions as a single JSONB column directly in the roles table. + +**Advantages:** +- Simplest database schema (single table) +- Very flexible structure +- No additional tables needed +- Fast to implement + +**Disadvantages:** +- Poor queryability (can't efficiently filter by specific permissions) +- No referential integrity +- Difficult to validate structure +- Hard to audit permission changes +- Can't leverage database indexes effectively + +**Verdict:** Rejected - Poor queryability makes it unsuitable for complex permission logic. + +--- + +### Approach 2: Normalized Database Tables + +Separate tables for `permission_sets`, `permission_set_resources`, `permission_set_pages` with full normalization. + +**Advantages:** +- Fully queryable with SQL +- Runtime configurable permissions +- Strong referential integrity +- Easy to audit changes +- Can index for performance + +**Disadvantages:** +- Complex database schema (4+ tables) +- DB queries required for every permission check +- Requires ETS cache for performance +- Needs admin UI for permission management +- Longer implementation time (4-5 weeks) +- Overkill for fixed set of 4 permission sets + +**Verdict:** Deferred to Phase 3 - Excellent for runtime configuration but too complex for MVP. + +--- + +### Approach 3: Custom Authorizer + +Implement a custom Ash Authorizer from scratch instead of using Ash Policies. + +**Advantages:** +- Complete control over authorization logic +- Can implement any custom behavior +- Not constrained by Ash Policy DSL + +**Disadvantages:** +- Significantly more code to write and maintain +- Loses benefits of Ash's declarative policies +- Harder to test than built-in policy system +- Mixes declarative and imperative approaches +- Must reimplement filter generation for queries +- Higher bug risk + +**Verdict:** Rejected - Too much custom code, reduces maintainability and loses Ash ecosystem benefits. + +--- + +### Approach 4: Simple Role Enum + +Add a simple `:role` enum field directly on User resource with hardcoded checks in each policy. + +**Advantages:** +- Very simple to implement (< 1 week) +- No extra tables needed +- Fast performance +- Easy to understand + +**Disadvantages:** +- No separation between roles and permissions +- Can't add new roles without code changes +- No dynamic permission configuration +- Not extensible to field-level permissions +- Violates separation of concerns (role = job function, not permission set) +- Difficult to maintain as requirements grow + +**Verdict:** Rejected - Too inflexible, doesn't meet requirement for configurable permissions and role separation. + +--- + +### Approach 5: Hardcoded Permissions with Migration Path (SELECTED for MVP) + +Permission Sets hardcoded in Elixir module, only Roles table in database. + +**Advantages:** +- Fast implementation (2-3 weeks vs 4-5 weeks) +- Maximum performance (zero DB queries, < 1 microsecond) +- Simple to test (pure functions) +- Code-reviewable permissions (visible in Git) +- No migration needed for existing data +- Clearly defined 4 permission sets as required +- Clear migration path to database-backed solution (Phase 3) +- Maintains separation of roles and permission sets + +**Disadvantages:** +- Permissions not editable at runtime (only role assignment possible) +- New permissions require code deployment +- Not suitable if permissions change frequently (> 1x/week) +- Limited to the 4 predefined permission sets + +**Why Selected:** +- MVP requirement is for 4 fixed permission sets (not custom ones) +- No stated requirement for runtime permission editing +- Performance is critical for authorization checks +- Fast time-to-market (2-3 weeks) +- Clear upgrade path when runtime configuration becomes necessary + +**Migration Path:** +When runtime permission editing becomes a business requirement, migrate to Approach 2 (normalized DB tables) without changing the public API of the PermissionSets module. + +--- + +## Requirements Summary + +### Four Predefined Permission Sets + +1. **own_data** - Access only to own user account and linked member profile +2. **read_only** - Read access to all members and custom fields +3. **normal_user** - Create/Read/Update members and full CRUD on custom fields (no member deletion for safety) +4. **admin** - Unrestricted access to all resources including user management + +### Example Roles + +- **Mitglied (Member)** - Uses "own_data" permission set, default role +- **Vorstand (Board)** - Uses "read_only" permission set +- **Kassenwart (Treasurer)** - Uses "normal_user" permission set +- **Buchhaltung (Accounting)** - Uses "read_only" permission set +- **Admin** - Uses "admin" permission set + +### Authorization Levels + +**Resource Level (MVP):** +- Controls create, read, update, destroy actions on resources +- Resources: Member, User, Property, PropertyType, Role + +**Page Level (MVP):** +- Controls access to LiveView pages +- Example: "/members/new" requires Member.create permission + +**Field Level (Phase 2 - Future):** +- Controls read/write access to specific fields +- Example: Only Treasurer can see payment_history field + +### Special Cases + +1. **Own Credentials:** Users can always edit their own email and password +2. **Linked Member Email:** Only admins can edit email of members linked to users +3. **User-Member Linking:** Only admins can link/unlink users to members (except self-service creation) + +--- + +## Selected Architecture + +### Conceptual Model + +``` +Elixir Module: PermissionSets + ↓ (defines) +Permission Set (:own_data, :read_only, :normal_user, :admin) + ↓ (referenced by) +Role (stored in DB: "Vorstand" → "read_only") + ↓ (assigned to) +User (each user has one role_id) +``` + +### Database Schema (MVP) + +**Single Table: roles** + +Contains: +- id (UUID) +- name (e.g., "Vorstand") +- description +- permission_set_name (String: "own_data", "read_only", "normal_user", "admin") +- is_system_role (boolean, protects critical roles) + +**No Permission Tables:** Permission Sets are hardcoded in Elixir module. + +### Why This Approach? + +**Fast Implementation:** 2-3 weeks instead of 4-5 weeks + +**Maximum Performance:** +- Zero database queries for permission checks +- Pure function calls (< 1 microsecond) +- No caching needed + +**Code Review:** +- Permissions visible in Git diffs +- Easy to review changes +- No accidental runtime modifications + +**Clear Upgrade Path:** +- Phase 1 (MVP): Hardcoded +- Phase 2: Add field-level permissions +- Phase 3: Migrate to database-backed with admin UI + +**Meets Requirements:** +- Four predefined permission sets ✓ +- Dynamic role creation ✓ (Roles in DB) +- Role-to-user assignment ✓ +- No requirement for runtime permission changes stated + +--- + +## Permission System Design + +### Permission Structure + +Each Permission Set contains: + +**Resources:** List of resource permissions +- resource: "Member", "User", "Property", etc. +- action: :read, :create, :update, :destroy +- scope: :own, :linked, :all +- granted: true/false + +**Pages:** List of accessible page paths +- Examples: "/", "/members", "/members/:id/edit" +- "*" for admin (all pages) + +### Scope Definitions + +**:own** -

All records without restriction +- Example: Admin can read all Members + +### How Authorization Works + +1. User attempts action on resource (e.g., read Member) +2. System loads user's role from database +3. Role contains permission_set_name string +4. PermissionSets module returns permissions for that set +5. Custom Policy Check evaluates permissions against action +6. Access granted or denied based on scope + +### Custom Policy Check + +A reusable Ash Policy Check that: +- Reads user's permission_set_name from their role +- Calls PermissionSets.get_permissions/1 +- Matches resource + action against permissions list +- Applies scope filters (own/linked/all) +- Returns authorized, forbidden, or filtered query + +--- + +## User-Member Linking Strategy + +### Problem Statement + +Users need to create member profiles for themselves (self-service), but only admins should be able to: +- Link existing members to users +- Unlink members from users +- Create members pre-linked to arbitrary users + +### Selected Approach: Separate Ash Actions + +Instead of complex field-level validation, we use action-based authorization. + +### Actions on Member Resource + +**1. create_member_for_self** (All authenticated users) +- Automatically sets user_id = actor.id +- User cannot specify different user_id +- UI: "Create My Profile" button + +**2. create_member** (Admin only) +- Can set user_id to any user or leave unlinked +- Full flexibility for admin +- UI: Admin member management form + +**3. link_member_to_user** (Admin only) +- Updates existing member to set user_id +- Connects unlinked member to user account + +**4. unlink_member_from_user** (Admin only) +- Sets user_id to nil +- Disconnects member from user account + +**5. update** (Permission-based) +- Normal updates (name, address, etc.) +- user_id NOT in accept list (prevents manipulation) +- Available to users with Member.update permission + +### Why Separate Actions?

+Implemented user-member linking functionality in User Edit/Create views with fuzzy search autocomplete, email conflict handling, and accessibility support. + +**Key Features:** +- Autocomplete dropdown with PostgreSQL Trigram fuzzy search +- Link/unlink members to user accounts +- Email synchronization between linked entities +- WCAG 2.1 AA compliant (ARIA labels) +- Bilingual UI (English/German) + +### Technical Decisions + +**1. Search Priority Logic** +Search query takes precedence over email filtering to provide better UX: +- User types → fuzzy search across all unlinked members +- Email matching only used for post-filtering when no search query present + +**2. JavaScript Hook for Input Value** +Used minimal JavaScript (~6 lines) for reliable input field updates: +```javascript +// assets/js/app.js +window.addEventListener("phx:set-input-value", (e) => { + document.getElementById(e.detail.id).value = e.detail.value +}) +``` +**Rationale:** LiveView DOM patching has race conditions with rapid state changes in autocomplete components. Direct DOM manipulation via `push_event` is the idiomatic LiveView solution for this edge case. + +**3. Fuzzy Search Implementation** +Combined PostgreSQL Full-Text Search + Trigram for optimal results: +```sql +-- FTS for exact word matching +search_vector @@ websearch_to_tsquery('simple', 'greta') +-- Trigram for typo tolerance +word_similarity('gre', first_name) > 0.2 +-- Substring for email/IDs +email ILIKE '%greta%' +``` + +### Key Learnings + +#### 1. Ash `manage_relationship` Internals +**Critical Discovery:** During validation, relationship data lives in `changeset.relationships`, NOT `changeset.attributes`: + +```elixir +# During validation (manage_relationship processing): +changeset.relationships.member = [{[%{id: "uuid"}], opts}] +changeset.attributes.member_id = nil # Still nil! + +# After action completes: +changeset.attributes.member_id = "uuid" # Now set +``` + +**Solution:** Extract member_id from both sources: +```elixir +defp get_member_id_from_changeset(changeset) do + case Map.get(changeset.relationships, :member) do + [{[%{id: id}], _opts}] -> id # New link + _ -> Ash.Changeset.get_attribute(changeset, :member_id) # Existing + end +end +``` + +**Impact:** Fixed email validation false positives when linking user+member with identical emails. + +#### 2. LiveView + JavaScript Integration Patterns + +**When to use JavaScript:** +- ✅ Direct DOM manipulation (autocomplete, input values) +- ✅ Browser APIs (clipboard, geolocation) +- ✅ Third-party libraries + +**When NOT to use JavaScript:** +- ❌ Form submissions +- ❌ Simple show/hide logic +- ❌ Server-side data fetching + +**Pattern:** +```elixir +socket |> push_event("event-name", %{key: value}) +``` +```javascript +window.addEventListener("phx:event-name", (e) => { /* handle */ }) +``` + +#### 3. PostgreSQL Trigram Search +Requires `pg_trgm` extension with GIN indexes: +```sql +CREATE INDEX members_first_name_trgm_idx + ON members USING GIN(first_name gin_trgm_ops); +``` +Supports: +- Typo tolerance: "Gret" finds "Greta" +- Partial matching: "Mit" finds "Mitglied" +- Substring: "exam" finds "example.com" + +#### 4. Test-Driven Development for Bug Fixes +Effective workflow: +1. Write test that reproduces bug (should fail) +2. Implement minimal fix +3. Verify test passes +4.
