Declares helper accessors for controller attributes. For example, the following adds new name and name= instance methods to a controller and makes them available to the view:
helper_attr :name attr_accessor :name
*attrs<Array[String, Symbol]> |
Names of attributes to be converted |
into helpers.
# File lib/action_controller/metal/helpers.rb, line 80 def helper_attr(*attrs) attrs.flatten.each { |attr| helper_method(attr, "#{attr}=") } end
Provides a proxy to access helpers methods from outside the view.
# File lib/action_controller/metal/helpers.rb, line 85 def helpers @helper_proxy ||= ActionView::Base.new.extend(_helpers) end
