link_to :confirm displays popup twice

Question

This tag with rails 3

<%= link_to \'Destroy\', item, :method => :delete,:confirm=>\'Are you sure?\' %>

produces this html

Answer 1

In my case jQuery was loaded twice because of the line //= require_tree .

To prevent this error in application.js and application.css I'm used to create a subdirectory app/assets/javascript/autorequire and instead of require_tree . I do require_tree ./autorequire.

So, files in app/assets/javascript and app/assets/stylesheets are not included automatically/accidentally anymore. I put all my individual .css and .js files into the subdirectory and they are included implicitly. But I can define which files from the top-path are to be included and in which order.

Since I do so, I never had troubles by assets not loaded as I expect them to be.
