Every link_to on my rails 4 application is being called twice

I'm experiencing some unusual behaviour with my Rails 4 Application. Every single-time I click on a link_to inside my views, my controllers actions are being called twice. For example:

In my root_url I have this standard call for users_profile:

<%= link_to('User Profile', users_profile_path, :class => "logout-button") %>

When I click this link, my console shows the following output:

Started GET "/users/profile" for 127.0.0.1 at 2013-11-25 20:45:53 -0200

People often have this behaviour when there's a remote (JS for example) calling the method, but this is not my case. the weirdest part is that, if I put the direct URL to the users_profile_path on my browser. I only get one request on my rails console:

Started GET "/users/profile" for 127.0.0.1 at 2013-11-25 20:48:17 -0200

  InvestorProfile Load (0.3ms)  SELECT "investor_profiles".* FROM "investor_profiles" WHERE "investor_profiles"."user_id" = $1 ORDER BY "investor_profiles"."id" ASC LIMIT 1  [["user_id", 45]]
  EmployeeProfile Load (0.2ms)  SELECT "employee_profiles".* FROM "employee_profiles" WHERE "employee_profiles"."user_id" = $1 ORDER BY "employee_profiles"."id" ASC LIMIT 1  [["user_id", 45]]
  Rendered users/sessions/_investor_setup.html.erb (3.4ms)
  Rendered users/sessions/profile.html.erb within layouts/application (4.2ms)
Completed 200 OK in 12ms (Views: 7.7ms | ActiveRecord: 1.1ms)

I'm getting this same result for every link inside my application, not only this one.

Solution

If you would like your app to still make use of Turbolinks then "Opting out of Turbolinks" on the code that is giving you problems is the way to go; just add data-no-turbolink.

I was having problems with using Bootstrap 3 and adding that fixed it. For example;

<li class="list-group-item" data-no-turbolink>
  <%= link_to download_path(item) do %>
    <button type="button" class="btn btn-success">Download</button>
  <% end %>
</li>
