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).
Encapsulates the interaction with the view flow so it returns the correct
yield. This is usually overwritten by helpers to add
# File actionview/lib/action_view/context.rb, line 31 def _layout_for(name = nil) name ||= :layout view_flow.get(name).html_safe end
Prepares the context by setting the appropriate instance variables.
# File actionview/lib/action_view/context.rb, line 22 def _prepare_context @view_flow = OutputFlow.new @output_buffer = nil @virtual_path = nil end
