- What's this?
ActionController::Metal is the simplest possible controller, providing a valid Rack interface without the additional niceties provided by ActionController::Base.
A sample metal controller might look like this:
class HelloController < ActionController::Metal def index self.response_body = "Hello World!" end end
And then to route requests to your metal controller, you would add something like this to config/routes.rb:
get 'hello', to: HelloController.action(:index)
The action method returns a valid Rack application for the Rails router to dispatch to.
Rendering Helpers
ActionController::Metal by default provides no utilities for rendering views, partials, or other responses aside from explicitly calling of response_body=, content_type=, and status=. To add the render helpers you’re used to having in a normal controller, you can do the following:
class HelloController < ActionController::Metal include ActionController::Rendering append_view_path "#{Rails.root}/app/views" def index render "hello/index" end end
Redirection Helpers
To add redirection helpers to your metal controller, do the following:
class HelloController < ActionController::Metal include ActionController::Redirecting include Rails.application.routes.url_helpers def index redirect_to root_url end end
Other Helpers
You can refer to the modules included in ActionController::Base to see other features you can bring into your metal controller.
