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

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

in app\views\layouts\application.html.erb, I can see the map in my
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:

  •            <a href="#" class="dropdown-toggle" 


                 Account <b class="caret"></b>
               <ul class="dropdown-menu">
                 <li><%= link_to "Profile", current_user %></li>
                 <li><%= link_to "Settings", '#' %></li>
                 <li class="divider"></li>
                   <%= 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 //=
    in application.js . What I do wrong?

  • If you delete the javascript_include_tag “application” from your layout,
    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”.
