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
