module Context
Ruby on Rails 4.0.13
Since v3.0.20Action 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).
