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 Action Controller, 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.

📝 Source code 
# File actionview/lib/action_view/context.rb, line 27
    def _layout_for(name = nil)
      name ||= :layout
      view_flow.get(name).html_safe
    end
