Module: JavascriptAutoInclude::Helpers::ActionView

Defined in:
lib/javascript_auto_include/helpers/action_view.rb

Overview

ActionView helpers

This module contains the helper javascript_auto_include_tag, which inserts the javascript include tag(s) into a view.

Basic usage

<%= javascript_auto_include_tag :defaults %>

… will insert the default javascripts (just like javascript_include_tag) and also look for an action-specifc javascript file at public/javascripts/:controller/:action.js. If it exists, it will be included as well.

Using your own pattern

<%= javascript_auto_include_tag :defaults, :pattern => ':controller_:action.js' %>

… will work just like shown above but alter the search path according to the supplied pattern: public/javascripts/:controller_:action.js (e.g. public/javascripts/album_new.js)

Compatibility

javascript_auto_include_tag uses Rails’ javascript_include_tag helper and passes on all options (:concat, :cache, …) and keys (:defaults, :all, …) supplied
