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

It sounds like the confirmation handler Javascript in rails.js is being attached twice.

Could you be accidentally including two copies of rails.js via duplication of a javascript_include_tag helper?

Answer 2

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.

Answer 3

I'm using Rails 4 and none of the answers worked for me, however the following worked... I changed the line:

<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %> 

to

<%= javascript_include_tag 'application', 'data-turbolinks-eval' => false %>.

Answer 4

I've had the same problem with Rails 3.2.12, but simply updating to 3.2.13 solved that problem for me.

Answer 5

In my case, it was that the application had both "mootools ujs" and "jquery ujs" included. I got rid of the mootools one and now I only see one confirmation.

Answer 6

In the layout haml like this have the twice pop up problem

%head
  = stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track': 'reload'
  = javascript_include_tag 'application', 'data-turbolinks-track': 'reload'
%body
  #calendar.calendarsize

Then I commend it and it works.

%head
  = stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track': 'reload'
  -#= javascript_include_tag 'application', 'data-turbolinks-track': 'reload'
%body
  #calendar.calendarsize
