Instance Method Details

#render(*args) ⇒ Object

Overrides the default render() method to call a subclass’ pre_render() method if it is present. Because the pre_render() method is called before the actual render() method, it is a good place for the controller to compose the “view model” based on the view being rendered before the actual render() method is called.

Parameters:

  • args —

    Arguments passed to the original render() method.
