Instance Method Details

#controller(base_class = nil, &body) ⇒ Object

Note:

Due to Ruby 1.8 scoping rules in anoymous subclasses, constants defined in ‘ApplicationController` must be fully qualified (e.g. `ApplicationController::AccessDenied`) in the block passed to the `controller` method. Any instance methods, filters, etc, that are defined in `ApplicationController`, however, are accessible from within the block.

Supports a simple DSL for specifying behavior of ApplicationController. Creates an anonymous subclass of ApplicationController and evals the ‘body` in that context. Also sets up implicit routes for this controller, that are separate from those defined in “config/routes.rb”.

If you would like to spec a subclass of ApplicationController, call controller like so:

controller(ApplicationControllerSubclass) do
  # ....
end

Examples:


describe ApplicationController do
  controller do
    def index
      raise ApplicationController::AccessDenied
    end
  end

  describe "handling AccessDenied exceptions" do
    it "redirects to the /401.html page" do
      get :index
      response.should redirect_to("/401.html")
    end
  end
end
