Action View Context

Action View contexts are supplied to Action Controller to render a template. The default Action View context is ActionView::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).

Methods
#
Attributes
[RW] output_buffer
[RW] view_flow
Instance Public methods
_layout_for(name = nil)

Encapsulates the interaction with the view flow so it returns the correct buffer on yield. This is usually overwritten by helpers to add more behavior. :api: plugin

Prepares the context by setting the appropriate instance variables. :api: plugin
