Uncaught ReferenceError: $ is not defined rails

I'm trying to add Froala editor to my project.

Problem only on production server(on localhost it works fine) I'm using rails 4.1.0 In gemfile i'm have

gem 'jquery-rails'

In my assets/javascripts/application.js:

//= require jquery
//= require jquery_ujs
//= require foundation
//= require turbolinks
//= require_tree .
//= require modernizr
//= require froala_editor.min.js

In new.html.erb file:

<div class="row">
  <%= form_for :article do |f| %>
    <p>
        Title<br>
        <%= f.text_field :title %>
    </p>
    <p>
        Content<br>
    <%= f.text_area :text, :id=>'content' %>
    <p>
    <%= f.submit %>
    </p>
  <% end %>
</div>
<script>
  $(function() {
    $('div#content').editable({
      inlineMode: false
    })
  });
</script>

In application.html.erb:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" /> 
    <title><%= content_for?(:title) ? yield(:title) : "foundation-rails" %></title>
    <%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track' => true %>
    <%= javascript_include_tag "vendor/modernizr" %>
    <%= javascript_include_tag "application" 'data-turbolinks-track' => true %>
    <%= csrf_meta_tags %>
  </head>
  <body>
    <%= yield %>
  </body>
</html>

In this case result is:

Uncaught ReferenceError: $ is not defined

If i'm adding a string:

<script src="//code.jquery.com/jquery-1.11.2.min.js"></script>

result is:

Uncaught TypeError: undefined is not a function

Replace application.html.erb

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

<%= javascript_include_tag "application" %>

This was my solution:

Put this in your app/assets/javascripts/application.js

//= require jquery
//= require jquery_ujs

and install this gem file:

gem 'jquery-rails'

try switching these lines:

<%= javascript_include_tag "vendor/modernizr" %>
<%= javascript_include_tag "application" 'data-turbolinks-track' => true %>

will become

<%= javascript_include_tag "application" 'data-turbolinks-track' => true %>
<%= javascript_include_tag "vendor/modernizr" %>

How do you have the foundation added to the project?

In app/assets/javascripts/aplication.js

I had the same error

$ is no defined

and I resolved by reloading the foundation js this way:

jQuery(document).ready(function($) {
$(document).foundation();
});

An solution working for me is:

Separate files

create assets/javascripts/jquery_init.js content :

//= require jquery
//= require jquery.turbolinks
//= require jquery.cookie
//= require jquery.ui.all
//= require jquery_ujs

an call before aplication.js

<%= javascript_include_tag "jquery_init" %>
<%= javascript_include_tag "application", :async => !Rails.env.development?, "turbolinks-data-track" => true %>
