Don't work JavaScript pipeline. Need help. =(

Hello. I need some help with pipeline. I try build application with openlayer3. I compile ol.js. I put ol.js to /assets/javascripts/ . If I use

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


in app\views\layouts\application.html.erb, I can see the map in my pages, but if i delete this line from file i can’t see map. Why this happend?

And another problem. I use bootstrap. I try create dropdown menu. I use:

  • Account
    • <%= link_to "Profile", current_user %>
    • <%= link_to "Settings", '#' %>
    • <%= link_to "Sign out", signout_path, method: "delete" %>
  • ``

    but menu don’t work. I start rails server, then press Account and do nothing. I think don’t work js path of bootstrap. But I add //= bootstrap in application.js . What I do wrong?

    If you delete the javascript_include_tag “application” from your layout, it won’t load the pipelined javascripts.

    According to the bootstrap-sass README, you need to put the following:

    Require Bootstrap Javascripts in app/assets/javascripts/application.js:
    //= require jquery
    //= require bootstrap-sprockets

    Notice it says “bootstrap-sprockets”, not “bootstrap”.
