Rails Controller Patterns

Generate controllers following standard Rails RESTful conventions (7 actions, resourceful routing, before_actions, strong params).

Core Principles

1. Thin controllers: Handle HTTP concerns only; delegate business logic to its axis-appropriate home — on Axis A (rails-stack-profiles), native delegates to models and concerns, extracted delegates to service objects
2. RESTful by default: Stick to 7 standard actions; create new resource controllers for custom actions
3. Strong parameters always: Never trust user input; use params.expect (Rails 8+)
4. Consistent responses: redirect_to after success, render :action, status: on failure
5. One resource per controller: Avoid multi-resource controllers
6. Dedicated resource controllers: Prefer Cards::ClosuresController over post :close on CardsController

Strong Parameters: params.expect (Rails 8+)
