Overview

Global CRUD controller that handles all registered models. Mirrors the Laravel GlobalController exactly.

Routes pass the model slug via route defaults, and this controller resolves the appropriate ActiveRecord class to operate on.

#computed ⇒ Object

GET /api/slug/computed?attributes=a,b

Collection-level computed attributes: each declared callable is evaluated ONCE over the whole (scoped + filtered) relation instead of once per row, which is what makes aggregates such as active_users_count cheap.

The relation handed to each callable has the organization scope, the model's default scopes, ?scope=, ?filter[]= and ?search= already applied — so the numbers describe exactly the set index would have listed. Sorting, sparse fieldsets, includes and pagination are deliberately NOT applied.

Omitting ?attributes= returns every declared attribute the policy allows.
