Let's look at what happens when you do something like this inside of a view:

<%= render partial: 'some_partial' -%>

To render a partial, Rails has a helper method inside of Action View. The render method serves as a delegator and takes its input arguments and provides them to the view_renderer object.

The view_renderer object is initialized when ActionView::Base is initialized and is of the ActionView::Renderer class. This class performs all of the rendering that is necessary inside of the views. The design pattern of delegating to an object is used. When you call view_renderer.render, you are asking the view_renderer object to delegate the arguments of your call to another more specific object.
