Question

Rails 3.0.11, Ruby 1.9.3

When I use a javascript_include_tag(“js/datepicker”) in my view file
it includes 2 files.

<script src="/js/datepicker.js?1336410184" type="text/javascript"></script>
<script src="/javascripts/widgets/tooltip.js?1332959153" type="text/javascript"></script>

Note the second one I didn’t specified, still its getting included.

I have following folders and files:

/public/javascripts
/public/javascripts/widgets
/public/javascripts/widgets/tooltip.js

/public/js
/public/js/datepicker.js

My application uses Prototype and jQuery.The datepicker.js is actually the Protoplasm Datepicker control.

/config/application.rb

config.action_view.javascript_expansions[:defaults] = %w(jquery jquery_ujs jquery.prettyPhoto)

Can anybody please make me understand what is the cause behind /javascripts/widgets/tooltip.js getting automatically included?

Thanks,

Ok I found the answer.

Following is the plugin included in my application:

rails-widgets-jquery (http://github.com/paolodona/rails-widgets/wikis)

A file named core.rb of this plugin at rails-widgets-jquery/lib/widgets/core.rb

redefines the javascript_include_tag which is causing the behavior mentioned in my question.

Source Code below:

module ActionView
 module Helpers
   module AssetTagHelper

  # We redefine javascript_include_tag in order to auto-magically include
  # the widgets javascripts. If you hame more than one javascript_include_tag
  # call, the widgets javascripts gets included only once.
  def javascript_include_tag_with_widgets(*sources)
    unless @__widgets_has_already_included_its_js
      options = sources.last.is_a?(Hash) ? sources.pop : {} # remove options
      sources << 'widgets/tooltip'
      sources << options # add previously removed option
      @__widgets_has_already_included_its_js = true
    end 
    javascript_include_tag_without_widgets(*sources)
  end
  alias_method_chain :javascript_include_tag, :widgets 
  end
 end
end

Thanks @Salil for your responses.Those helped me getting to above answer.
