defmodule Mv.Membership.CustomField do
|
|
@moduledoc """
|
|
Ash resource defining the schema for custom member fields.
|
|
|
|
## Overview
|
|
CustomFields define the "schema" for custom fields in the membership system.
|
|
Each CustomField specifies the name, data type, and behavior of a custom field
|
|
that can be attached to members via CustomFieldValue resources.
|
|
|
|
## Attributes
|
|
- `name` - Unique identifier for the custom field (e.g., "phone_mobile", "birthday")
|
|
- `value_type` - Data type constraint (`:string`, `:integer`, `:boolean`, `:date`, `:email`)
|
|
- `description` - Optional human-readable description
|
|
- `immutable` - If true, custom field values cannot be changed after creation
|
|
- `required` - If true, all members must have this custom field (future feature)
|
|
|
|
## Supported Value Types
|
|
- `:string` - Text data (unlimited length)
|
|
- `:integer` - Numeric data (64-bit integers)
|
|
- `:boolean` - True/false flags
|
|
- `:date` - Date values (no time component)
|
|
- `:email` - Validated email addresses
|
|
|
|
## Relationships
|
|
- `has_many :custom_field_values` - All custom field values of this type
|
|
|
|
## Constraints
|
|
- Name must be unique across all custom fields
|
|
- Cannot delete a custom field that has existing custom field values (RESTRICT)
|
|
|
|
## Examples
|
|
# Create a new custom field
|
|
CustomField.create!(%{
|
|
name: "phone_mobile",
|
|
value_type: :string,
|
|
description: "Mobile phone number"
|
|
})
|
|
|
|
# Create a required custom field
|
|
CustomField.create!(%{
|
|
name: "emergency_contact",
|
|
value_type: :string,
|
|
required: true
|
|
})
