Code Review: HasPermission Policy Check
|
|
||||||
|
|
||||||
Gesamtbewertung: Gut ✅
|
|
||||||
|
|
||||||
Positiv:
|
|
||||||
- Korrekte Ash.Policy.Check Implementierung mit strict_check/3 und auto_filter/3
|
|
||||||
- Umfassende Fehlerbehandlung (nil actor, nil role, invalid permission_set_name)
|
|
||||||
- Gute Test Coverage (~25 Tests)
|
|
||||||
- Die Relationship-Pfade sind korrekt - Member hat has_one :user (lib/membership/member.ex:517)
|
|
||||||
|
|
||||||
Kleinere Punkte:
|
|
||||||
- Dokumentation zwischen Moduledoc und Architecture Doc sollte vereinheitlicht werden
|
|
||||||
- Die Architektur-Dokumentation beschreibt user_id, die Implementierung nutzt user.id (funktional äquivalent, aber inkonsistent dokumentiert)
|
|
||||||
|
|
||||||
Merge-Empfehlung: ✅ Kann gemerged werden

│ Code Review: HasPermission Policy Check (Issue #6) │
|
|
||||||
│ │
|
|

│ Branch: feature/343_haspermission │
|
|
||||||
│ Base: main │

|
|
||||||
│ Zusammenfassung │
|
|
||||||
│ │
|
|
||||||
│ Der Branch implementiert den HasPermission Policy Check (Issue #6 aus │
|
|
||||||
│ dem Implementation Plan). Dies ist eine zentrale Komponente des Rollen- │
|
|
||||||
│ und Berechtigungssystems, die Berechtigungen aus dem PermissionSets │
|
|
||||||
│ Modul ausliest und auf Ash Policies anwendet. │
|
|
||||||
│ │
|
|
||||||
│ Geänderte Dateien: │
|
|
||||||
│ - lib/mv/authorization/checks/has_permission.ex (neu, 239 Zeilen) │
|
|
||||||
│ - test/mv/authorization/checks/has_permission_test.exs (neu, 264 Zeilen)│
|
|
||||||
│ - test/mv/authorization/checks/has_permission_integration_test.exs (neu,│
|
|
||||||
│ 87 Zeilen) │
|
|
||||||
│ │
|
|
||||||
│ --- │
|
|
||||||
│ Positives │
|
|
||||||
│ │
|
|
||||||
│ 1. Saubere Architektur │
|
|
||||||
│ │
|
|
||||||
│ - Korrekte Implementierung von Ash.Policy.Check mit strict_check/3 und │
|
|
||||||
│ auto_filter/3 │
|
|
||||||
│ - Gute Separation of Concerns - Berechtigungslogik delegiert an │
|
|
||||||
│ PermissionSets Modul │
|
|
||||||
│ - Klare Modulstruktur mit Helper-Funktionen zur Reduktion von Nesting │
|
|
||||||
│ │
|
|
||||||
│ 2. Fehlerbehandlung │
|
|
||||||
│ │
|
|
||||||
│ - Umfassende Behandlung von Edge Cases (nil actor, nil role, invalid │
|
|
||||||
│ permission_set_name) │
|
|
||||||
│ - Graceful degradation - Fehler führen zu {:ok, false} statt Crashes │
|
|
||||||
│ - Debug-Logging für Autorisierungsfehler (lazy evaluation mit │
|
|
||||||
│ Logger.debug(fn -> ... end)) │
|
|
||||||
│ │
|
|
||||||
│ 3. Scope-Implementierung │
|
|
||||||
│ │
|
|
||||||
│ - Korrekte Implementierung aller drei Scopes: :all, :own, :linked │
|
|
||||||
│ - Wichtig: Die :linked Scope-Implementierung für CustomFieldValue │
|
|
||||||
│ traversiert korrekt die Relationship (member.user.id) │
|
|
||||||
│ - Die Filter-Expressions verwenden korrekt Ash.Expr │
|
|
||||||
│ │
|
|
||||||
│ 4. Test Coverage │
|
|
||||||
│ │
|
|
||||||
│ - Umfassende Unit Tests für alle Szenarien │
|
|
||||||
│ - Separate Integration Tests für Filter-Expression-Struktur │
|
|
||||||
│ - Tests für Error Handling und Logging │
|
|
||||||
│ │
|
|
||||||
│ --- │
|
|
||||||
│ Kritische Punkte │
|
|
||||||
│ │
|
|
||||||
│ 1. VERIFIZIERT: Relationship-Pfade in apply_scope/3 sind korrekt │
|
|
||||||
│ │
|
|
||||||
│ Die Implementierung verwendet: │
|
|
||||||
│ # Member (Zeile 191) │
|
|
||||||
│ {:filter, expr(user.id == ^actor.id)} │
|
|
||||||
│ │
|
|
||||||
│ # CustomFieldValue (Zeile 196) │
|
|
||||||
│ {:filter, expr(member.user.id == ^actor.id)} │
|
|
||||||
│ │
|
|
||||||
│ Verifiziert: Member hat has_one :user, Mv.Accounts.User │
|
|
||||||
│ (lib/membership/member.ex:517) │
|
|
||||||
│ │
|
|
||||||
│ Die Architektur-Dokumentation beschreibt member.user_id == actor.id, │
|
|
||||||
│ aber die Implementierung nutzt bewusst die Relationship user.id. Beides │
|
|
||||||
│ ist funktional äquivalent, da Ash die Relationship auflöst. │
|
|
||||||
│ │
|
|
||||||
│ HINWEIS: Der Commit db0a1870 ("fix: correct relationship filter paths") │
|
|
||||||
│ zeigt, dass dies eine bewusste Design-Entscheidung war, um Ash │
|
|
||||||
│ Relationship-Traversal zu nutzen statt direkter Foreign Key-Vergleiche. │
|
|
||||||
│ │
|
|
||||||
│ 2. Moduledoc entspricht nicht der Architektur-Dokumentation │
|
|
||||||
│ │
|
|
||||||
│ Der @moduledoc beschreibt die :linked Scope für Member als: │
|
|
||||||
│ - Member: member.user.id == actor.id (via has_one :user relationship) │
|
|
||||||
│ │
|
|
||||||
│ Die Architektur-Dokumentation sagt jedoch: │
|
|
||||||
│ - Member: member.user_id == actor.id (direct relationship) │
|
|
||||||
│ │
|
|
||||||
│ Empfehlung: Dokumentation vereinheitlichen. │
|
|
||||||
│ │
|
|
||||||
│ 3. FEHLER: match?/3 nicht implementiert │
|
|
||||||
│ │
|
|
||||||
│ Der Implementation Plan (Issue #6) spezifiziert: │
|
|
||||||
│ 4. Implement `match?/3` - the core authorization logic │
|
|
||||||
│ │
|
|
||||||
│ Die Implementierung verwendet stattdessen strict_check/3 und │
|
|
||||||
│ auto_filter/3. │
|
|
||||||
│ │
|
|
||||||
│ Bewertung: Dies ist kein Fehler - strict_check/3 und auto_filter/3 sind │
|
|
||||||
│ die korrekten Callbacks für Ash.Policy.Check. Die Dokumentation im │
|
|
||||||
│ Implementation Plan ist veraltet. Die Implementierung ist korrekt. │
|
|
||||||
│ │
|
|
||||||
│ 4. Error-Return-Typen │
|
|
||||||
│ │
|
|
||||||
│ Der Implementation Plan spezifiziert Error-Returns wie {:error, │
|
|
||||||
│ :no_actor}, aber die Implementierung gibt {:ok, false} zurück. │
|
|
||||||
│ │
|
|
||||||
│ Bewertung: Korrekt. Ash.Policy.Check erwartet {:ok, true | false | │
|
|
||||||
│ :unknown}, nicht {:error, ...}. Die Implementierung ist konform mit der │
|
|
||||||
│ Ash API. │
|
|
||||||
│ │
|
|
||||||
│ --- │
|
|
||||||
│ Verbesserungsvorschläge │
|
|
||||||
│ │
|
|
||||||
│ 1. Code: Fallback in apply_scope(:linked, ...) könnte problematisch sein│
|
|
||||||
│ │
|
|
||||||
│ # Zeile 199-200 │
|
|
||||||
│ _ -> │
|
|
||||||
│ {:filter, expr(user.id == ^actor.id or user_id == ^actor.id)} │
|
|
||||||
│ │
|
|
||||||
│ Dieser Fallback könnte zu unerwarteten Ergebnissen führen, wenn ein │
|
|
||||||
│ Resource weder user noch user_id hat. │
|
|
||||||
│ │
|
|
||||||
│ Empfehlung: Explizite Fehlerbehandlung statt Fallback oder Logging wenn │
|
|
||||||
│ der Fallback verwendet wird. │
|
|
||||||
│ │
|
|
||||||
│ 2. Tests: Integration Tests sind minimal │
|
|
||||||
│ │
|
|
||||||
│ Die Integration Tests (has_permission_integration_test.exs) testen nur │
|
|
||||||
│ die Struktur der Filter-Expressions, nicht deren Korrektheit in echten │
|
|
||||||
│ Queries. │
|
|
||||||
│ │
|
|
||||||
│ Empfehlung: Nach Implementierung der Resource Policies (Issues #7-#10) │
|
|
||||||
│ sollten End-to-End Tests hinzugefügt werden. │
|
|
||||||
│ │
|
|
||||||
│ 3. Tests: Fehlende Tests für describe/1 │
|
|
||||||
│ │
|
|
||||||
│ Der Test für describe/1 (Zeile 23-27) testet nur, dass ein String │
|
|
||||||
│ zurückgegeben wird, nicht den Inhalt. │
|
|
||||||
│ │
|
|
||||||
│ Minimal: Akzeptabel, da describe/1 nur für Logging/Debugging verwendet │
|
|
||||||
│ wird. │
|
|
||||||
│ │
|
|
||||||
│ 4. Performance: Logger.debug könnte optimiert werden │
|
|
||||||
│ │
|
|
||||||
│ Die Logging-Funktion log_auth_failure/4 erstellt einen String auch wenn │
|
|
||||||
│ Debug-Logging deaktiviert ist. │
|
|
||||||
│ │
|
|
||||||
│ Aktuell: Die Implementierung verwendet bereits lazy evaluation mit │
|
|
||||||
│ Logger.debug(fn -> ... end). Gut! │
|
|
||||||
│ │
|

│ Fazit │
|
|
||||||
│ │
|
|
||||||
│ Gesamtbewertung: Gut (mit Hinweisen) │
|
|
||||||
│ │
|
|
||||||
│ Die Implementierung ist solide und entspricht weitgehend den │
|
|
||||||
│ Anforderungen aus der Architektur-Dokumentation. Die wichtigsten Punkte:│
|
|
||||||
│ │
|
|
||||||
│ Positiv: │
|
|
||||||
│ - Korrekte Ash.Policy.Check Implementierung │
|
|
||||||
│ - Umfassende Fehlerbehandlung │
|
|
||||||
│ - Gute Test Coverage │
|
|
||||||
│ - Sauberer, lesbarer Code │
|
|
||||||
│ │
|
|
||||||
│ Zu Klären: │
|
|
||||||
│ 1. Relationship-Pfade (user.id vs user_id) - scheint bewusst so │
|
|
||||||
│ implementiert (siehe Commit-Message), sollte aber dokumentiert werden │
|
|
||||||
│ 2. Dokumentation zwischen Code und Architecture Doc vereinheitlichen │
|
|
||||||
│ │
|
|
||||||
│ Merge-Empfehlung: ✅ Kann gemerged werden, nachdem die Dokumentation │
|
|
||||||
│ aktualisiert wurde │
|

|

|
|

│ │
|
|
||||||
│ - ~~Verify: Member hat has_one :user Relationship~~ → Bestätigt │
|
|

# Implementation Plan: Member Resource Policies + Review-Verbesserungen
|
|
||||||
|
|
||||||
**Issue:** #7 (Member Resource Policies) + Code Review Verbesserungen
|
|
||||||
**Branch:** `feature/343_haspermission`
|
|
||||||
**Abhängigkeiten:** Issue #6 (HasPermission) ✅ bereits implementiert

|
|
||||||
|
|
||||||
## Übersicht
|
|
||||||
|
|
||||||
Dieser Plan implementiert:
|
|
||||||
1. **Member Resource Policies** gemäß Issue #7
|
|
||||||
2. **Dokumentations-Synchronisation** aus dem Code Review
|
|
||||||
3. **Fallback-Verbesserung** in HasPermission für robustere Fehlerbehandlung

# =========================================================================

# Policy Order (WICHTIG!):
|
|
||||||
# 1. Special Case: User kann immer eigenes verknüpftes Mitglied
|
|
||||||
lesen/bearbeiten
|
|
||||||
# 2. General: HasPermission Check für alle anderen Fälle
|
|
||||||
# 3. Default: Forbid (implizit durch Ash wenn keine Policy matched)
|
|
||||||
# =========================================================================
|
|
||||||
|
|
||||||
# SPECIAL CASE: User kann sein verknüpftes Mitglied immer lesen/bearbeiten
|
|
||||||
# Diese Policy greift VOR dem HasPermission Check
|
|

#### 1.2 Actor-Preparation für Role-Loading
|
|
||||||
|
|
||||||
**Position:** Nach `policies do ... end` Block
|
|
||||||
|
|
||||||
```elixir
|
|
||||||
# Ensure actor has role preloaded for policy checks
|
|
||||||
preparations do
|
|
||||||
prepare build(actor_context: [role: [:permission_set_name]])
|
|
||||||
end
|
|
||||||
```
|
|
||||||
|
|
||||||
**ALTERNATIV** (falls Ash 3.0 andere Syntax benötigt):
|
|
||||||
Die Role muss im Actor bereits geladen sein. Prüfen ob `Mv.Accounts.User`
|
|
||||||
bereits `:role` preloaded.

## Teil 2: Dokumentations-Synchronisation
|
|
||||||
|
|
||||||
### 2.1 Datei: `lib/mv/authorization/checks/has_permission.ex`
|
|
||||||
|
|
||||||
**Zeile 23-25:** Moduledoc aktualisieren für Konsistenz mit Code
|
|
||||||
|
|
||||||
```elixir
|
|
||||||
# VORHER:
|
|
||||||
# - Member: member.user.id == actor.id (via has_one :user relationship)
|
|
||||||
# - CustomFieldValue: custom_field_value.member.user.id == actor.id (traverses
|
|
||||||
member → user relationship!)
|
|
||||||
|
|
||||||
# NACHHER (konsistent mit tatsächlichem Code):
|
|
||||||
## Scope Behavior
|
|
||||||
|
|
||||||
- **:all** - Authorizes without filtering (returns all records)
|
|
||||||
- **:own** - Filters to records where record.id == actor.id
|
|
||||||
- **:linked** - Filters based on resource type using Ash relationship traversal:
|
|
||||||
- Member: `user.id == actor.id` (traverses has_one :user relationship)
|
|
||||||
- CustomFieldValue: `member.user.id == actor.id` (traverses belongs_to :member
|
|
||||||
→ has_one :user)
|
|
||||||
- Other resources: Falls back to `user.id == actor.id or user_id == actor.id`
|
|
||||||
```
|

||||||
### 2.2 Datei: `docs/roles-and-permissions-architecture.md`

# VORHER:
|
|
||||||
# - Member: member.user_id == actor.id
|

# - CustomFieldValue: custom_field_value.member.user_id == actor.id
|
|

# NACHHER (konsistent mit Implementation):

# This fallback is intentionally permissive - logs warning for investigation

## Ausführungsreihenfolge
|
|
||||||
|
|
||||||
### Schritt 1: HasPermission Verbesserungen (5 min)
|
|
||||||

|
|
||||||
2. Finde Position nach `relationships do ... end` (ca. Zeile 528)
|
|
||||||
3. Füge `policies do ... end` Block ein
|
|
||||||
4. Optional: Prüfe ob actor preparation nötig
|
|
||||||
|
|
||||||
### Schritt 3: Dokumentation aktualisieren (5 min)
|
|
||||||
1. Update `docs/roles-and-permissions-architecture.md` Zeilen 799-812
|
|
||||||
|
|
||||||
### Schritt 4: Tests schreiben (15 min)

|
|
||||||
|
|
||||||
### Schritt 5: Validierung (5 min)

## Dateien die geändert werden
|
|
||||||
|
|
||||||
| Datei | Änderung |
|
|
||||||
|-------|----------|
|
|
||||||
| `lib/membership/member.ex` | `policies do` Block hinzufügen (~15 Zeilen) |
|
|
||||||
| `lib/mv/authorization/checks/has_permission.ex` | Moduledoc + Fallback-Logging
|
|
||||||
(~10 Zeilen) |
|
|
||||||
| `docs/roles-and-permissions-architecture.md` | Scope-Dokumentation
|
|
||||||
aktualisieren (~5 Zeilen) |
|
|
||||||
| `test/membership/member_policies_test.exs` | Neue Datei (~150 Zeilen) |

## Risiken und Mitigationen
|
|
||||||
|
|
||||||
| Risiko | Mitigation |
|
|
||||||
|--------|------------|
|
|
||||||
| Policy-Order falsch | Special Case MUSS vor General stehen |
|
|
||||||
| Actor ohne Role | HasPermission handhabt das bereits graceful |
|
|
||||||
| Bestehende Tests brechen | Tests mit `actor: user` Parameter aktualisieren |
|
|
||||||
| Performance | Minimal - Policies werden nur bei Queries evaluiert |
|
|
||||||
|
|
||||||
---
|
|
||||||
|
|
||||||
## Akzeptanzkriterien (aus Issue #7)
|
|
||||||
|
|
||||||
- [x] Policies block added to Member resource
|
|
||||||
- [ ] All CRUD actions protected by HasPermission
|
|
||||||
- [ ] Special case: User can always access linked member
|
|
||||||
- [ ] Policy order is correct (specific before general)
|
|
||||||
- [ ] Actor preloads :role relationship
|
|
||||||
- [ ] All policies tested

|
||||||
|
|
||||||
## Project Overview
|
|
||||||
|
|
||||||
**Mila** is a self-hostable membership management system for small to mid-sized clubs, built with Elixir/Phoenix and the Ash Framework.
|
|
||||||
|
|
||||||
**Tech Stack:**
|
|
||||||
- Elixir 1.18.3 / Erlang/OTP 27.3.4
|
|
||||||
- Phoenix 1.8 with LiveView 1.1
|
|
||||||
- Ash Framework 3.0 with AshPostgres, AshAuthentication, AshPhoenix
|
|
||||||
- PostgreSQL 17 (dev) / 16 (prod)
|
|
||||||
- Tailwind CSS 4 + DaisyUI
|
|
||||||
- Just (task runner)
|
|
||||||
|
|
||||||
## Essential Commands

|
||||||
## Architecture
|
|
||||||
|
|
||||||
### Ash Domains (lib/)
|
|
||||||
|
|
||||||
The codebase follows domain-driven design using Ash Framework:
|
|
||||||
|
|
||||||
- **`lib/accounts/`** - User authentication domain (AshAuthentication)
|
|
||||||
- `User` - Authenticated users with OIDC/password strategies
|
|
||||||
- `Token` - Auth tokens
|
|
||||||
|
|
||||||
- **`lib/membership/`** - Core membership domain
|
|
||||||
- `Member` - Club members with personal information
|
|
||||||
- `CustomField` - Admin-defined custom fields
|
|
||||||
- `CustomFieldValue` - Values for custom fields per member
|
|
||||||
- `Setting` - Application settings
|
|
||||||
|
|
||||||
- **`lib/membership_fees/`** - Fee management domain
|
|
||||||
- `MembershipFeeType` - Fee type definitions
|
|
||||||
- `MembershipFeeCycle` - Fee cycles
|
|
||||||
|
|
||||||
- **`lib/mv/authorization/`** - Authorization domain (in development)
|
|
||||||
- `Role` - User roles referencing permission sets
|
|
||||||
- `PermissionSets` - Permission definitions
|
|
||||||
|
|
||||||
- **`lib/mv/`** - Core application modules
|
|
||||||
- `email_sync/` - Email synchronization between User and Member
|
|
||||||
- `repo.ex`, `application.ex`, `secrets.ex`
|
|
||||||
|
|
||||||
- **`lib/mv_web/`** - Phoenix web layer
|
|
||||||
- `live/` - LiveView modules
|
|
||||||
- `components/` - Reusable UI components
|
|
||||||
- `controllers/` - HTTP controllers
|
|
||||||
|
|
||||||
### Key Patterns
|
|
||||||
|
|
||||||
**Ash Resources:** Each resource defines its own actions, validations, policies, and code interface. Use the domain's code interface for all operations:
|
|
||||||
```elixir
|
|
||||||
Mv.Membership.create_member(attrs) # Not Ash.create(Member, attrs)
|
|
||||||
```
|
|
||||||
|
|
||||||
**Email Sync:** User and Member emails are synchronized - User email is the source of truth.
|
|
||||||
|
|
||||||
**LiveView:** Primary UI pattern. Controllers are thin; delegate to Ash domains.
|
|
||||||
|
|
||||||
## Testing
|
|
||||||
|
|
||||||
Tests mirror lib/ structure in `test/`. Use:
|
|
||||||
- `Mv.DataCase` for database tests
|
|
||||||
- `MvWeb.ConnCase` for controller/LiveView tests
|
|
||||||
- `async: true` when possible for parallel execution
|
|
||||||
|
|
||||||
## Important Notes
|
|
||||||
|
|
||||||
- Run `just ci-dev` before each commit to catch issues
|
|
||||||
- All modules require `@moduledoc` documentation (enforced by Credo)
|
|
||||||
- Follow existing Ash DSL section ordering (see `.formatter.exs` Spark config)
|
|
||||||
- Commit messages use conventional format: `feat:`, `fix:`, `docs:`, `refactor:`, `test:`, `chore:`
|
|
||||||
- Refer to `CODE_GUIDELINES.md` for detailed coding standards
|
|
||||||
- Refer to `docs/` for feature-specific documentation

# Code Review Fixes - Membership Fee Features
|
|
||||||
|
|
||||||
## Kritische Probleme (Müssen vor Merge behoben werden)
|
|
||||||
|
|
||||||
### 1. after_action mit Task.start - Transaktionsprobleme
|
|
||||||
|
|
||||||
**Dateien:** `lib/membership/member.ex` (Zeilen 142, 279)
|
|
||||||
|
|
||||||
**Problem:** `Task.start/1` wird innerhalb von `after_action` Hooks verwendet. `after_action` läuft innerhalb der DB-Transaktion, daher:
|
|
||||||
|
|
||||||
- Tasks sehen möglicherweise noch nicht committed state
|
|
||||||
- Tasks werden auch bei Rollback gestartet
|
|
||||||
- Keine Supervision → Memory Leaks möglich
|
|
||||||
|
|
||||||
**Lösung:**
|
|
||||||
|
|
||||||
- `after_transaction` Hook verwenden (Ash Best Practice)
|
|
||||||
- `Task.Supervisor` zum Supervision Tree hinzufügen (`lib/mv/application.ex`)
|
|
||||||
- `Task.Supervisor.async_nolink/3` statt `Task.start/1` verwenden
|
|
||||||
|
|
||||||
**Betroffene Stellen:**
|
|
||||||
|
|
||||||
- Member Creation (Zeile 116-164)
|
|
||||||
- Join/Exit Date Change (Zeile 250-301)
|
|
||||||
|
|
||||||
### 2. Code-Duplikation in Cycle-Generation-Logik
|
|
||||||
|
|
||||||
**Datei:** `lib/membership/member.ex`
|
|
||||||
|
|
||||||
**Problem:** Cycle-Generation-Logik ist dreimal dupliziert (Create, Type Change, Date Change)
|
|
||||||
|
|
||||||
**Lösung:** Extrahiere in private Funktion `handle_cycle_generation/2`
|
|
||||||
|
|
||||||
## Wichtige Probleme (Sollten behoben werden)
|
|
||||||
|
|
||||||
### 3. join_date Validierung entfernt, aber Dokumentation behauptet Gegenteil
|
|
||||||
|
|
||||||
**Datei:** `lib/membership/member.ex` (Zeile 27, 516-518)
|
|
||||||
|
|
||||||
**Problem:** Dokumentation sagt "join_date not in future", aber Validierung fehlt
|
|
||||||
|
|
||||||
**Lösung:** Dokumentation anpassen
|
|
||||||
|
|
||||||
### 4. load_cycles_for_members overpromises
|
|
||||||
|
|
||||||
**Datei:** `lib/mv_web/member_live/index/membership_fee_status.ex` (Zeile 36-40)
|
|
||||||
|
|
||||||
**Problem:** Dokumentation sagt "Only loads the relevant cycle per member" und "Filters cycles at database level", aber lädt alle Cycles
|
|
||||||
|
|
||||||
**Lösung:** echte Filterung implementieren (z.B. nur letzte 2 Intervalle)
|
|
||||||
|
|
||||||
### 5. get_current_cycle nondeterministisch
|
|
||||||
|
|
||||||
**Datei:** `lib/mv_web/helpers/membership_fee_helpers.ex` (Zeile 178-182)
|
|
||||||
|
|
||||||
**Problem:** `List.first()` ohne explizite Sortierung → Ergebnis hängt von Reihenfolge ab
|
|
||||||
|
|
||||||
**Lösung:** Vor `List.first()` nach `cycle_start` sortieren (desc)
|
|
||||||
|
|
||||||
### 6. N+1 Query durch get_member_count
|
|
||||||
|
|
||||||
**Datei:** `lib/mv_web/live/membership_fee_type_live/index.ex` (Zeile 134-140)
|
|
||||||
|
|
||||||
**Problem:** `get_member_count/1` wird pro Row aufgerufen → N+1 Query
|
|
||||||
|
|
||||||
**Lösung:** Aggregate auf MembershipFeeType definieren oder einmalig vorab laden
|
|
||||||
|
|
||||||
### 7. assign_new kann stale werden
|
|
||||||
|
|
||||||
**Datei:** `lib/mv_web/live/member_live/show/membership_fees_component.ex` (Zeile 402-403)
|
|
||||||
|
|
||||||
**Problem:** `assign_new(:cycles, ...)` und `assign_new(:available_fee_types, ...)` werden nur gesetzt, wenn Assign noch nicht existiert
|
|
||||||
|
|
||||||
**Lösung:** In `update/2` immer `assign(:cycles, cycles)` / `assign(:available_fee_types, available_fee_types)` setzen
|
|
||||||
|
|
||||||
### 8. @regenerating wird nie auf true gesetzt
|
|
||||||
|
|
||||||
**Datei:** `lib/mv_web/live/member_live/show/membership_fees_component.ex` (Zeile 526-561)
|
|
||||||
|
|
||||||
**Problem:** `regenerating` wird nur auf `false` gesetzt, nie auf `true` → Button/Spinner werden nie disabled
|
|
||||||
|
|
||||||
**Lösung:** Direkt beim Event-Start `socket |> assign(:regenerating, true)` setzen
|
|
||||||
|
|
||||||
### 9. Create-cycle parsing: invalid amount zeigt falsche Fehlermeldung
|
|
||||||
|
|
||||||
**Datei:** `lib/mv_web/live/member_live/show/membership_fees_component.ex` (Zeile 748-812)
|
|
||||||
|
|
||||||
**Problem:** `Decimal.parse/1` gibt `:error` zurück, aber `with` behandelt es als `:error` → landet in "Invalid date format" Branch
|
|
||||||
|
|
||||||
**Lösung:** Explizit `{:error, :invalid_amount}` zurückgeben:
|
|
||||||
|
|
||||||
```elixir
|
|
||||||
amount = case Decimal.parse(amount_str) do
|
|
||||||
{d, _} -> {:ok, d}
|
|
||||||
:error -> {:error, :invalid_amount}
|
|
||||||
end
|
|
||||||
```
|
|
||||||
|
|
||||||
### 10. Delete all cycles: nicht atomar
|
|
||||||
|
|
||||||
**Datei:** `lib/mv_web/live/member_live/show/membership_fees_component.ex` (Zeile 666-714)
|
|
||||||
|
|
||||||
**Problem:** `Enum.map(cycles, &Ash.destroy/1)` → nicht atomar, teilweise gelöscht möglich
|
|
||||||
|
|
||||||
**Lösung:** Bulk Delete Query verwenden (Ash bulk destroy oder Query-basiert)
|
|
||||||
|
|
||||||
### 11. Fehlerbehandlung bei async Tasks
|
|
||||||
|
|
||||||
**Datei:** `lib/membership/member.ex`
|
|
||||||
|
|
||||||
**Problem:** Bei Fehlern in async Tasks wird nur geloggt, aber der Benutzer erhält keine Rückmeldung. Die Member-Aktion wird als erfolgreich zurückgegeben, auch wenn die Cycle-Generierung fehlschlägt. Keine Retry-Logik oder Monitoring.
|
|
||||||
|
|
||||||
**Lösung:**
|
|
||||||
|
|
||||||
- Für kritische Fälle: synchron ausführen oder Retry-Mechanismus implementieren
|
|
||||||
- Für nicht-kritische Fälle: Event-System für spätere Benachrichtigung
|
|
||||||
- Strukturierte Error-Logs mit Context
|
|
||||||
- Optional: Error-Tracking (Sentry, etc.)
|
|
||||||
|
|
||||||
### 12. format_currency Robustheit
|
|
||||||
|
|
||||||
**Datei:** `lib/mv_web/helpers/membership_fee_helpers.ex` (Zeilen 27-51)
|
|
||||||
|
|
||||||
**Problem:** Die Funktion verwendet String-Manipulation für Formatierung. Edge Cases könnten problematisch sein (z.B. sehr große Zahlen, negative Werte).
|
|
||||||
|
|
||||||
**Lösung:**
|
|
||||||
|
|
||||||
- `Number.Currency` oder ähnliche Bibliothek verwenden
|
|
||||||
- Oder: Robusteres Pattern Matching für Edge Cases
|
|
||||||
- Tests für Edge Cases hinzufügen (negative Zahlen, sehr große Zahlen)
|
|
||||||
|
|
||||||
### 13. Fehlende Typespecs
|
|
||||||
|
|
||||||
**Datei:** `lib/membership/member/changes/set_default_membership_fee_type.ex`
|
|
||||||
|
|
||||||
**Problem:** Keine `@spec` für die `change/3` Funktion.
|
|
||||||
|
|
||||||
**Lösung:** Typespecs hinzufügen für bessere Dokumentation und Dialyzer-Support.
|
|
||||||
|
|
||||||
### 14. Potenzielle Race Condition
|
|
||||||
|
|
||||||
**Datei:** `lib/membership/member.ex` (Zeile 250-301)
|
|
||||||
|
|
||||||
**Problem:** Wenn `join_date` und `exit_date` gleichzeitig geändert werden, könnte die Cycle-Generierung zweimal ausgelöst werden (einmal pro Änderung).
|
|
||||||
|
|
||||||
**Lösung:** Prüfen, ob Ash dies bereits verhindert, oder Logik anpassen (z.B. beide Änderungen in einem Hook zusammenfassen).
|
|
||||||
|
|
||||||
### 15. Magic Numbers/Strings
|
|
||||||
|
|
||||||
**Problem:** `Application.get_env(:mv, :sql_sandbox, false)` wird mehrfach verwendet.
|
|
||||||
|
|
||||||
**Lösung:** Extrahiere in Konstante oder Helper-Funktion (z.B. `Mv.Config.sql_sandbox?/0`).
|
|
||||||
|
|
||||||
## Mittlere Probleme (Nice-to-have)
|
|
||||||
|
|
||||||
### 16. Inconsistent use of domain
|
|
||||||
|
|
||||||
**Datei:** `lib/mv_web/live/member_live/show/membership_fees_component.ex` (Zeile 819-821)
|
|
||||||
|
|
||||||
**Problem:** Einige Actions verwenden `domain: MembershipFees`, andere nicht
|
|
||||||
|
|
||||||
**Lösung:** Konsistent `domain` überall verwenden
|
|
||||||
|
|
||||||
### 17. Tests: create_cycle/3 löscht jedes Mal alle Cycles
|
|
||||||
|
|
||||||
**Datei:** `test/mv_web/member_live/index/membership_fee_status_test.exs` (Zeile 45-52)
|
|
||||||
|
|
||||||
**Problem:** Helper löscht vor jedem Create alle Cycles → Tests prüfen nicht, was sie denken
|
|
||||||
|
|
||||||
**Lösung:** Cleanup nur einmal im Setup oder gezielt nur auto-generierte löschen
|
|
||||||
|
|
||||||
### 18. Tests/Design: Date.utc_today() macht Tests flaky
|
|
||||||
|
|
||||||
**Problem:** Tests hängen von `Date.utc_today()` ab → nicht deterministisch
|
|
||||||
|
|
||||||
**Lösung:** `today` Parameter durchgeben (z.B. `get_cycle_status_for_member(member, show_current, today \\ Date.utc_today())`)
|
|
||||||
|
|
||||||
### 19. UI/Locale: input type="number" + Decimal/Komma
|
|
||||||
|
|
||||||
**Problem:** `type="number"` funktioniert nicht zuverlässig mit Komma als Dezimaltrenner
|
|
||||||
|
|
||||||
**Lösung:** `type="text"` + `inputmode="decimal"` + serverseitig "," → "." normalisieren
|
|
||||||
|
|
||||||
### 20. Delete-all-Confirmation: String-Vergleich ist fragil
|
|
||||||
|
|
||||||
**Datei:** `lib/mv_web/live/member_live/show/membership_fees_component.ex` (Zeile 296-298)
|
|
||||||
|
|
||||||
**Problem:** String-Vergleich gegen `gettext("Yes")` und `"Yes"` → fragil bei Whitespace/Locale
|
|
||||||
|
|
||||||
**Lösung:** `String.trim()` + case-insensitive Vergleich oder "type DELETE" Pattern
|
|
||||||
|
|
||||||
### 21. MembershipFeeType Form: Warning-State kann hängen bleiben
|
|
||||||
|
|
||||||
**Datei:** `lib/mv_web/live/membership_fee_type_live/form.ex` (Zeile 367-378)
|
|
||||||
|
|
||||||
**Problem:** Bei `Decimal.parse(:error)` wird nur `socket` zurückgegeben → Warning kann stehen bleiben
|
|
||||||
|
|
||||||
**Lösung:** Bei `:error` explizit `hide_amount_warning(socket)` aufrufen
|
|
||||||
|
|
||||||
### 22. UI/UX: Toggle ist doppelt vorhanden
|
|
||||||
|
|
||||||
**Datei:** `lib/mv_web/live/member_live/index.html.heex` (Zeile 45-72, 284-296)
|
|
||||||
|
|
||||||
**Problem:** Toggle-Button sowohl in Toolbar als auch im Spalten-Header
|
|
||||||
|
|
||||||
**Lösung:** Toggle im Spalten-Header entfernen (nur in Toolbar behalten)
|
|
||||||
|
|
||||||
### 23. Konsistenz: format_currency vs Inputs
|
|
||||||
|
|
||||||
**Problem:** `format_currency` formatiert deutsch (Komma), aber Inputs erwarten Punkt
|
|
||||||
|
|
||||||
**Lösung:** Inputs ebenfalls auf Komma ausrichten oder serverseitig normalisieren
|
|
||||||
|
|
||||||
## Implementierungsreihenfolge
|
|
||||||
|
|
||||||
1. **Kritisch:** after_action → after_transaction + Task.Supervisor
|
|
||||||
2. **Kritisch:** Code-Duplikation reduzieren
|
|
||||||
3. **Wichtig:** join_date Validierung/Dokumentation
|
|
||||||
4. **Wichtig:** load_cycles_for_members Dokumentation/Implementierung
|
|
||||||
5. **Wichtig:** get_current_cycle Sortierung
|
|
||||||
6. **Wichtig:** N+1 Query beheben
|
|
||||||
7. **Wichtig:** assign_new → assign
|
|
||||||
8. **Wichtig:** @regenerating auf true setzen
|
|
||||||
9. **Wichtig:** Create-cycle parsing Fix
|
|
||||||
10. **Wichtig:** Delete all cycles atomar
|
|
||||||
11. **Wichtig:** Fehlerbehandlung bei async Tasks
|
|
||||||
12. **Wichtig:** format_currency Robustheit
|
|
||||||
13. **Wichtig:** Fehlende Typespecs
|
|
||||||
14. **Wichtig:** Potenzielle Race Condition prüfen/beheben
|
|
||||||
15. **Wichtig:** Magic Numbers/Strings extrahieren
|
|
||||||
16. **Mittel:** Domain-Konsistenz
|
|
||||||
17. **Mittel:** Test-Helper Fix
|
|
||||||
18. **Mittel:** Date.utc_today() Parameter
|
|
||||||

# Learning: Ash Framework, Policies, Phoenix & Elixir
|
|
||||||
|
|
||||||
## Session Overview
|
|
||||||
This document captures key learnings from implementing authorization policies for the `Member` resource using Ash Framework 3.0.
|
|
||||||
|
|
||||||
---
|
|
||||||
|
|
||||||
## 1. Ash Framework Policies
|
|
||||||
|
|
||||||
### 1.1 Enabling Policies
|
|
||||||
- **Critical:** Policies require the `Ash.Policy.Authorizer` extension to be explicitly enabled
|
|
||||||
- Must be added in the resource definition:
|
|
||||||
```elixir
|
|
||||||
use Ash.Resource,
|
|
||||||
domain: Mv.Membership,
|
|
||||||
data_layer: AshPostgres.DataLayer,
|
|
||||||
authorizers: [Ash.Policy.Authorizer] # Required for policies!
|
|
||||||
```
|
|
||||||
- Without this, the `policies` DSL block will not be available and will cause compilation errors
|
|
||||||
|
|
||||||
### 1.2 Action Types vs Action Names
|
|
||||||
- **Key Discovery:** Policies match on **action types**, not specific action names
|
|
||||||
- Action Types: `:create`, `:read`, `:update`, `:destroy`
|
|
||||||
- Action Names: `:create_member`, `:update_member`, `:read_member`, etc.
|
|
||||||
|
|
||||||
**Problem:**
|
|
||||||
```elixir
|
|
||||||
# In HasPermission check - WRONG:
|
|
||||||
action = authorizer.subject.action.name # Returns :create_member
|
|
||||||
```
|
|
||||||
|
|
||||||
**Solution:**
|
|
||||||
```elixir
|
|
||||||
# In HasPermission check - CORRECT:
|
|
||||||
action = authorizer.subject.action_type # Returns :create
|
|
||||||
```
|
|
||||||
|
|
||||||
**Why this matters:** The `PermissionSets` module defines permissions by action type (`:create`, `:read`, etc.), not by specific action names. Extracting the action name instead of the action type caused permission lookups to fail.
|
|
||||||
|
|
||||||
### 1.3 Policy Structure
|
|
||||||
```elixir
|
|
||||||
policies do
|
|
||||||
# Policy order matters! Specific before general
|
|
||||||
|
|
||||||
# Special cases first (optional)
|
|
||||||
policy action_type(:read) do
|
|
||||||
description "Special case for linked members"
|
|
||||||
authorize_if SomeCustomCheck
|
|
||||||
end
|
|
||||||
|
|
||||||
# General authorization
|
|
||||||
policy action_type([:read, :create, :update, :destroy]) do
|
|
||||||
description "Standard permission check"
|
|
||||||
authorize_if HasPermission
|
|
||||||
end
|
|
||||||
end
|
|
||||||
```
|
|
||||||
|
|
||||||
### 1.4 Policy Directives
|
|
||||||
- `authorize_if`: Grants access if check passes
|
|
||||||
- `forbid_if`: Denies access if check passes
|
|
||||||
- `bypass`: Allows access if check passes, skipping remaining policies
|
|
||||||
- `policy do ... end`: Groups multiple checks together
|
|
||||||
|
|
||||||
### 1.5 Policy Evaluation Results
|
|
||||||
Custom policy checks can return:
|
|
||||||
- `{:ok, true}`: Authorization granted
|
|
||||||
- `{:ok, false}`: Authorization denied
|
|
||||||
- `{:ok, :unknown}`: Let other policies evaluate
|
|
||||||
|
|
||||||
**Use Case:** The `NoActor` check returns `:unknown` when an actor is present, allowing other policies to take over:
|
|
||||||
```elixir
|
|
||||||
def strict_check(actor, _authorizer, _opts) do
|
|
||||||
if is_nil(actor) do
|
|
||||||
{:ok, true} # Allow if no actor (for seeds)
|
|
||||||
else
|
|
||||||
{:ok, :unknown} # Let other policies decide
|
|
||||||
end
|
|
||||||
end
|
|
||||||
```
|
|
||||||
|
|
||||||
---
|
|
||||||
|
|
||||||
## 2. Custom Policy Checks
|
|
||||||
|
|
||||||
### 2.1 Structure
|
|
||||||
```elixir
|
|
||||||
defmodule Mv.Authorization.Checks.MyCheck do
|
|
||||||
use Ash.Policy.Check
|
|
||||||
|
|
||||||
@impl true
|
|
||||||
def describe(_opts), do: "description for debugging"
|
|
||||||
|
|
||||||
@impl true
|
|
||||||
def strict_check(actor, authorizer, _opts) do
|
|
||||||
# Runtime authorization logic
|
|
||||||
{:ok, true | false | :unknown}
|
|
||||||
end
|
|
||||||
|
|
||||||
@impl true
|
|
||||||
def auto_filter(actor, authorizer, _opts) do
|
|
||||||
# Query filter for list operations
|
|
||||||
nil | {:filter, expr(...)}
|
|
||||||
end
|
|
||||||
end
|
|
||||||
```
|
|
||||||
|
|
||||||
### 2.2 strict_check vs auto_filter
|
|
||||||
- **`strict_check`:** Called for single record operations (get, create, update, destroy)
|
|
||||||
- **`auto_filter`:** Called for list/query operations to filter results
|
|
||||||
|
|
||||||
**Critical:** Both must be implemented correctly for comprehensive authorization!
|
|
||||||
|
|
||||||
**Example from HasPermission:**
|
|
||||||
```elixir
|
|
||||||
def strict_check(actor, authorizer, _opts) do
|
|
||||||
# Check single record authorization
|
|
||||||
has_permission?(actor, authorizer)
|
|
||||||
end
|
|
||||||
|
|
||||||
def auto_filter(actor, authorizer, _opts) do
|
|
||||||
# Return filter for list queries
|
|
||||||
case get_scope(actor, authorizer) do
|
|
||||||
:all -> nil # No filter needed
|
|
||||||
:linked -> {:filter, expr(id == ^actor.member_id)}
|
|
||||||
_ -> {:error, :forbidden}
|
|
||||||
end
|
|
||||||
end
|
|
||||||
```
|
|
||||||
|
|
||||||
---
|
|
||||||
|
|
||||||
## 3. Inverse Relationships & Authorization
|
|
||||||
|
|
||||||
### 3.1 The Problem
|
|
||||||
When implementing the "linked member" special case, initial attempts failed:
|
|
||||||
```elixir
|
|
||||||
# WRONG: Tries to traverse from Member to User
|
|
||||||
policy action_type(:read) do
|
|
||||||
authorize_if expr(user.id == ^actor(:id))
|
|
||||||
end
|
|
||||||
```
|
|
||||||
|
|
||||||
**Error:** `user` relationship is not loaded/available in this context
|
|
||||||
|
|
||||||
### 3.2 Understanding the Relationship
|
|
||||||
```
|
|
||||||
User (member_id) ──FK──> Member (id)
|
|
||||||
^ |
|
|
||||||
└──── has_one :user ─┘ (inverse)
|
|
||||||
```
|
|
||||||
|
|
||||||
- `User` table has `member_id` column (foreign key)
|
|
||||||
- `Member` has `has_one :user` (inverse relationship)
|
|
||||||
- **No foreign key on Member table pointing to User!**
|
|
||||||
|
|
||||||
### 3.3 The Solution
|
|
||||||
Check the relationship from the correct direction:
|
|
||||||
```elixir
|
|
||||||
# CORRECT: Check if actor's member_id matches this member's id
|
|
||||||
policy action_type(:read) do
|
|
||||||
authorize_if expr(^actor(:member_id) == id)
|
|
||||||
end
|
|
||||||
```
|
|
||||||
|
|
||||||
### 3.4 Applying to Scopes
|
|
||||||
In `HasPermission.apply_scope/3` for `:linked` scope:
|
|
||||||
|
|
||||||
```elixir
|
|
||||||
case resource_name do
|
|
||||||
"Member" ->
|
|
||||||
# Member has_one :user (inverse), FK is on User side
|
|
||||||
{:filter, expr(id == ^actor.member_id)}
|
|
||||||
|
|
||||||
"CustomFieldValue" ->
|
|
||||||
# CustomFieldValue belongs_to :member
|
|
||||||
# User.member_id → Member.id → CustomFieldValue.member_id
|
|
||||||
{:filter, expr(member.id == ^actor.member_id)}
|
|
||||||
end
|
|
||||||
```
|
|
||||||
|
|
||||||
**Key Insight:** Always check which table has the foreign key!
|
|
||||||
|
|
||||||
---
|
|
||||||
|
|
||||||
## 4. SAT Solver for Policy Strictness
|
|
||||||
|
|
||||||
### 4.1 The Warning
|
|
||||||
```
|
|
||||||
No SAT solver is available, so some policy strictness checks cannot be run
|
|
||||||
```
|
|
||||||
|
|
||||||
### 4.2 The Solution
|
|
||||||
Add a SAT solver dependency to `mix.exs`:
|
|
||||||
```elixir
|
|
||||||
{:picosat_elixir, "~> 0.1", only: [:dev, :test]}
|
|
||||||
```
|
|
||||||
|
|
||||||
### 4.3 Why It's Needed
|
|
||||||
Ash uses a SAT solver to verify that policies don't have logical contradictions or unreachable branches. This is a compile-time safety check.
|
|
||||||
|
|
||||||
---
|
|
||||||
|
|
||||||
## 5. Testing Authorization
|
|
||||||
|
|
||||||
### 5.1 Actor in Tests
|
|
||||||
**Critical:** Authorization requires an actor to be passed to all operations
|
|
||||||
|
|
||||||
```elixir
|
|
||||||
# Create with actor
|
|
||||||
{:ok, member} = Membership.create_member(%{...}, actor: user)
|
|
||||||
|
|
||||||
# Read with actor
|
|
||||||
{:ok, member} = Ash.get(Mv.Membership.Member, id, actor: user, domain: Mv.Membership)
|
|
||||||
|
|
||||||
# List with actor
|
|
||||||
members = Membership.list_members!(actor: user)
|
|
||||||
```
|
|
||||||
|
|
||||||
### 5.2 Reloading Actor After Relationships Change
|
|
||||||
**Problem:** After linking a member to a user, the `user` struct in memory doesn't have the updated `member_id`.
|
|
||||||
|
|
||||||
```elixir
|
|
||||||
# Link member to user
|
|
||||||
{:ok, member} = member
|
|
||||||
|> Ash.Changeset.for_update(:update_member, %{})
|
|
||||||
|> Ash.Changeset.manage_relationship(:user, user, type: :append_and_remove)
|
|
||||||
|> Ash.update(actor: admin_user)
|
|
||||||
|
|
||||||
# CRITICAL: Reload user to get updated member_id!
|
|
||||||
user = Ash.get!(Mv.Accounts.User, user.id, domain: Mv.Accounts)
|
|
||||||
# Now user.member_id is populated
|
|
||||||
```
|
|
||||||
|
|
||||||
### 5.3 Test Fixtures with Admin Actor
|
|
||||||
When creating test fixtures, use an admin actor to bypass authorization:
|
|
||||||
|
|
||||||
```elixir
|
|
||||||
defp create_member_linked_to(user) do
|
|
||||||
# Create admin for fixture setup
|
|
||||||
admin_user = create_admin_user()
|
|
||||||
|
|
||||||
# Create member as admin
|
|
||||||
{:ok, member} = Membership.create_member(%{...}, actor: admin_user)
|
|
||||||
|
|
||||||
# Link member as admin
|
|
||||||
{:ok, member} = member
|
|
||||||
|> Ash.Changeset.for_update(:update_member, %{})
|
|
||||||
|> Ash.Changeset.manage_relationship(:user, user, type: :append_and_remove)
|
|
||||||
|> Ash.update(actor: admin_user)
|
|
||||||
|
|
||||||
member
|
|
||||||
end
|
|
||||||
```
|
|
||||||
|
|
||||||
---
|
|
||||||
|
|
||||||
## 6. Database Seeding with Authorization
|
|
||||||
|
|
||||||
### 6.1 The Problem
|
|
||||||
Once policies are active, seed scripts fail because they don't have an authenticated actor:
|
|
||||||
|
|
||||||
```elixir
|
|
||||||
# In priv/repo/seeds.exs
|
|
||||||
Membership.create_member!(%{...}) # Ash.Error.Forbidden!
|
|
||||||
```
|
|
||||||
|
|
||||||
### 6.2 Solution: NoActor Check
|
|
||||||
Create a custom check that allows actions without an actor:
|
|
||||||
|
|
||||||
```elixir
|
|
||||||
defmodule Mv.Authorization.Checks.NoActor do
|
|
||||||
use Ash.Policy.Check
|
|
||||||
|
|
||||||
def describe(_opts), do: "allows if no actor is present"
|
|
||||||
|
|
||||||
def strict_check(actor, _authorizer, _opts) do
|
|
||||||
if is_nil(actor) do
|
|
||||||
{:ok, true} # Allow seeding
|
|
||||||
else
|
|
||||||
{:ok, :unknown} # Let other policies decide
|
|
||||||
end
|
|
||||||
end
|
|
||||||
|
|
||||||
def auto_filter(_actor, _authorizer, _opts), do: nil
|
|
||||||
end
|
|
||||||
```
|
|
||||||
|
|
||||||
Then add to policies:
|
|
||||||
```elixir
|
|
||||||
policy action_type(:create) do
|
|
||||||
description "Allow seeding without actor"
|
|
||||||
authorize_if NoActor
|
|
||||||
end
|
|
||||||
```
|
|
||||||
|
|
||||||
---
|
|
||||||
|
|
||||||
## 7. Debugging Policies
|
|
||||||
|
|
||||||
### 7.1 Enable Policy Breakdowns
|
|
||||||
Add to `config/test.exs`:
|
|
||||||
```elixir
|
|
||||||
config :ash, :policies, show_policy_breakdowns?: true
|
|
||||||
```
|
|
||||||
|
|
||||||
This shows detailed policy evaluation in test output.
|
|
||||||
|
|
||||||
### 7.2 NDJSON Logging
|
|
||||||
Structure for debug logs:
|
|
||||||
```elixir
|
|
||||||
defp log_debug(event, data) do
|
|
||||||
log_entry = %{
|
|
||||||
location: "has_permission.ex",
|
|
||||||
message: event,
|
|
||||||
data: data,
|
|
||||||
timestamp: System.system_time(:millisecond),
|
|
||||||
sessionId: "debug-session"
|
|
||||||
}
|
|
||||||
|
|
||||||
line = Jason.encode!(log_entry) <> "\n"
|
|
||||||
File.write!(".cursor/debug.log", line, [:append])
|
|
||||||
end
|
|
||||||
```
|
|
||||||
|
|
||||||
### 7.3 Strategic Log Placement
|
|
||||||
Place logs at:
|
|
||||||
1. **Function entry** with parameters
|
|
||||||
2. **Before critical operations** (e.g., before permission lookup)
|
|
||||||
3. **After critical operations** (e.g., after permission lookup with result)
|
|
||||||
4. **Branch execution** (which if/else path was taken)
|
|
||||||
5. **Function exit** with return value
|
|
||||||
|
|
||||||
### 7.4 Log Analysis Workflow
|
|
||||||
1. Delete old log file: `truncate -s 0 .cursor/debug.log`
|
|
||||||
2. Run failing test
|
|
||||||
3. Read log file line by line
|
|
||||||
4. Trace execution flow
|
|
||||||
5. Identify where actual behavior diverges from expected
|
|
||||||
|

|
|
||||||
## 8. Key Ash Concepts
|
|
||||||
|
|
||||||
### 8.1 Resources vs Domains
|
|
||||||
- **Resource:** Data model with attributes, relationships, actions (like `Member`)
|
|
||||||
- **Domain:** Logical grouping of resources (like `Membership`, `Accounts`)
|
|
||||||
- Domain must be specified in queries: `domain: Mv.Membership`
|
|
||||||
|
|
||||||
### 8.2 Actions
|
|
||||||
- **Create actions:** `:create`, `:create_member`
|
|
||||||
- **Read actions:** `:read`, `:get_member`, `:list_members`
|
|
||||||
- **Update actions:** `:update`, `:update_member`
|
|
||||||
- **Destroy actions:** `:destroy`, `:delete_member`
|
|
||||||
|
|
||||||
Each action has a **type** (one of the 4 above) and a **name** (specific)
|
|
||||||
|
|
||||||
### 8.3 Changesets
|
|
||||||
All modifications go through changesets:
|
|
||||||
```elixir
|
|
||||||
member
|
|
||||||
|> Ash.Changeset.for_update(:update_member, %{first_name: "New"})
|
|
||||||
|> Ash.Changeset.manage_relationship(:user, user, type: :append_and_remove)
|
|
||||||
|> Ash.update(actor: current_user)
|
|
||||||
```
|
|
||||||
|
|
||||||
---
|
|
||||||
|
|
||||||
## 9. Elixir Patterns
|
|
||||||
|
|
||||||
### 9.1 Pattern Matching in Policy Checks
|
|
||||||
```elixir
|
|
||||||
def strict_check(%{role: %{permissions: permissions}}, authorizer, _opts) do
|
|
||||||
# Actor has role with permissions
|
|
||||||
end
|
|
||||||
|
|
||||||
def strict_check(_actor, _authorizer, _opts) do
|
|
||||||
# Actor doesn't have role/permissions
|
|
||||||
{:ok, false}
|
|
||||||
end
|
|
||||||
```
|
|
||||||
|
|
||||||
### 9.2 With Expressions for Clean Authorization
|
|
||||||
```elixir
|
|
||||||
with %{role: %{permissions: permissions}} <- actor,
|
|
||||||
action <- get_action_from_authorizer(authorizer),
|
|
||||||
true <- check_permission(permissions, resource_name, action) do
|
|
||||||
{:ok, true}
|
|
||||||
else
|
|
||||||
_ -> {:ok, false}
|
|
||||||
end
|
|
||||||
```
|
|
||||||
|
|
||||||

|
|
||||||
|
|
||||||
## 10. Common Pitfalls & Solutions
|
|
||||||
|
|
||||||
| Pitfall | Symptom | Solution |
|
|
||||||
|---------|---------|----------|
|
|
||||||
| Missing `Ash.Policy.Authorizer` | `undefined function policies/1` | Add `authorizers: [Ash.Policy.Authorizer]` |
|
|
||||||
| Using action name instead of type | `check_permission_not_found` | Use `authorizer.subject.action_type` not `.action.name` |
|
|
||||||
| Wrong relationship direction | Policy expression fails | Check which table has the FK |
|
|
||||||
| Actor not reloaded | `member_id` is `nil` after link | Reload actor from DB after relationship changes |
|
|
||||||
| Missing `auto_filter` | List queries return 0 results | Implement `auto_filter` in custom checks |
|
|
||||||
| Seeds fail after adding policies | `Ash.Error.Forbidden` in seeds | Add `NoActor` check or provide admin actor |
|
|
||||||
|
|
||||||

|
|
||||||
|
|
||||||
## 11. Session Metrics
|
|
||||||
|
|
||||||
- **Duration:** Multiple hours of debugging
|
|
||||||
- **Primary Issues Fixed:** 3 major (policies not loading, action type mismatch, inverse relationship)
|
|
||||||
- **Debug Iterations:** ~10+ test runs with progressive instrumentation
|
|
||||||
- **Files Modified:** 6 (member.ex, has_permission.ex, tests, config, mix.exs, seeds)
|
|
||||||
- **Tests Created:** 15+ covering all permission sets
|
|
||||||
- **Lines of Debug Logging Added:** ~50+ (across multiple files)
|
|
||||||
|
|
||||||
---
|
|
||||||
|
|
||||||
## 12. Best Practices Established
|
|
||||||
|
|
||||||
1. **Always enable policy authorizer explicitly** in resource definition
|
|
||||||
2. **Match on action types, not names** in policies and permission checks
|
|
||||||
3. **Understand relationship direction** before writing authorization filters
|
|
||||||
4. **Reload actors after relationship changes** in tests
|
|
||||||
5. **Implement both `strict_check` and `auto_filter`** for comprehensive authorization
|
|
||||||
6. **Use `NoActor` check for seeding** instead of disabling policies
|
|
||||||
7. **Add SAT solver dependency** for policy validation
|
|
||||||
8. **Enable policy breakdowns in test config** for debugging
|
|
||||||
9. **Use NDJSON logging for complex debugging** with strategic placement
|
|
||||||
10. **Test all permission sets systematically** (own_data, read_only, normal_user, admin)
|
|
||||||

|
|
||||||
|
|
||||||
## 13. Architecture Decisions
|
|
||||||
|
|
||||||
### 13.1 HasPermission as Central Check
|
|
||||||
Rather than spreading authorization logic across multiple policy checks, we centralized it in `HasPermission`:
|
|
||||||
- Single source of truth for permission logic
|
|
||||||
- Permission sets defined in one module (`PermissionSets`)
|
|
||||||
- Scopes (`:all`, `:linked`) applied consistently
|
|
||||||
|
|
||||||
### 13.2 Policy Order
|
|
||||||
Keep policies simple with clear order:
|
|
||||||
1. Special cases first (if any)
|
|
||||||
2. General HasPermission check
|
|
||||||
3. Implicit forbid (by Ash)
|
|
||||||
|
|
||||||
### 13.3 Minimal Special Cases
|
|
||||||
Initially tried multiple special case policies for linked members. **Simplified to just use HasPermission with scope handling:**
|
|
||||||
- Less complex policy block
|
|
||||||
- Easier to reason about
|
|
||||||
- Scope logic centralized in one place
|

## 14. Future Considerations
|
|
||||||
|
|
||||||
1. **Performance:** Monitor query performance with authorization filters on large datasets
|
|
||||||
2. **Caching:** Consider caching permission lookups if they become a bottleneck
|
|
||||||
3. **Audit Logging:** Add audit trail for authorization decisions (who accessed what)
|
|
||||||
4. **Dynamic Permissions:** Current system uses static permission sets; might need dynamic permissions per user in future
|
|
||||||
5. **Policy Testing:** Consider property-based testing for policies to catch edge cases
|
|
||||||
6. **Documentation:** Keep permission set documentation in sync with code
