  Renderers are procs which tell for which key what proc to use to render the result.

  When you wrap your code in respond_to then formats need to be matched. Since there is no format called :simon your test fails. In order to make the test pass you need to use something like Mime::Type.register "text/simon", :simon . I have not tested my code but you need to register format :simon in order for your code to work .

  Hope that helps.

  I could be missing something about the way this should work in Rails 3 but in my test_using_custom_reneder_option in the code above I have a Mime::Type.register but the code does not work. I mistakenly put Mime::Type.register 'application/simon', :simon in the code above but it also fails when using Mime::Type.register 'text/simon', :simon. If the MIME type isn't registered then the test will error with:
  

    1) Error:
  test_using_custom_render_option(RenderOtherTest):
  NameError: uninitialized constant Mime::SIMON
  

  but if the MIME type :simon is registered like in my code in the original post then the test fails:
  

    1) Failure:
  test_using_custom_render_option(RenderOtherTest) [test/controller/render_other_test.rb:273]:
  <"Simon says: foo"> expected but was
  <" ">.
  

  It seems as though for a custom MIME type when put within a respond_to then the block associated with the custom render is never called.

  ActionController.add_renderer :simon do |says, options|
    self.content_type  = Mime::TEXT
    self.response_body = "Simon says: #{says}"
  end
  

  I've been stepping through the render code to see if I can find where the problem is. I've gotten to the point where I see that calling format.simon will create a new instance method simon in the class ActionController::MimeResponds::Collector using method_missing of the AbstractController::Collector module. It seems as though the &block of this method is never called which is why the custom render doesn't work in respond_to.

  • State changed from “new” to “resolved”

  In order to make the test pass this is what you need to do

    def test_using_custom_render_option
       Mime::Type.register 'text/simon', :simon
      get :render_simon_says, :format => :simon
      assert_equal "Simon says: foo", @response.body
    end
  
      def render_simon_says
        respond_to do |format|
         format.simon { render :simon => "foo" }
        end
      end
  

  Hope that helps.
