Instance Method Details

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

Supports a simple DSL for specifying behaviour 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.

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

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

controller(ApplicationControllerSubclass) do
 # ....
end

NOTICE: 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.
