Overview

Action View contexts are supplied to Action Controller to render a template. The default Action View context is Base.

In order to work with ::ActionController, a Context must just include this module. The initialization of the variables used by the context (@output_buffer, @view_flow, and @virtual_path) is responsibility of the object that includes this module (although you can call _prepare_context defined below).

Instance Method Summary

#_layout_for(name = nil)

Encapsulates the interaction with the view flow so it returns the correct buffer on yield.
#_prepare_context

Prepares the context by setting the appropriate instance variables.
