Rails Helpers in View - undefined local variable or method in rails

Question

I have this Helper in my ApplicationHelper

module ApplicationHelper
  def sort_url
    controller_name = params[:controller] 
    url = controller_name + '/sort' 
  end
end

And in application.js.erb

url: "<%= sort_url %>",

Error:

undefined local variable or method `sort_url'

Is it in `helpers/application_helper.rb` ? Can you use `sort_url` from a .html.erb file? — Anthony Alberto, Aug 17 '12 at 02:28

That is because the ApplicationHelper is only included in views by default.

The javascript file is not a view.

If you really want to use helpers in the view, you can use

<% environment.context_class.instance_eval { include MyHelper } %>
