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:
attr_accessor :name helper_attr :name
attrs
- Names of attributes to be converted into helpers.
# File lib/action_controller/metal/helpers.rb, line 73 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 78 def helpers @helper_proxy ||= ActionView::Base.new.extend(_helpers) end
Overwrite #modules_for_helpers to accept :all as argument, which loads all helpers in helpers_path.
args
- A list of helpers
array
- A normalized list of modules for the list of helpers
provided.
# File lib/action_controller/metal/helpers.rb, line 90 def modules_for_helpers(args) args += all_application_helpers if args.delete(:all) super(args) end
