I have a problem in my rails app that jQuery is included twice. Once it's referenced normally with a script tag and once minimized inside application.js. I noticed it because the destroy confirmation messages were popping up twice.
So is there a way to turn off the minimized version locally?
My head looks like:
<head>
<title>Wirent</title>
<%= stylesheet_link_tag "application" %>
<%= javascript_include_tag "application" %>
<%= csrf_meta_tags %>
</head>
My application.js looks like:
//...
//= require jquery
//= require jquery_ujs
//= require_tree .
It's because I pre-compiled my assets. So assets were also being loaded from public/assets.

I have a rails application which I added the bootstrap gem
first I added this two gems
gem 'bootstrap'
gem 'sprockets-rails', :require => 'sprockets/railtie'
which installed this packages
Using bootstrap 4.0.0.alpha3
Using sprockets 3.6.0
After I modified application.scss to
// Custom bootstrap variables must be set or import before bootstrap itself.
#import "bootstrap";
Then I left application.js like this
// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or any plugin's vendor/assets/javascripts directory can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// compiled file.
//
// Read Sprockets README (https://github.com/rails/sprockets#sprockets-directives) for details
// about supported directives.
//
//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require tether
//= require bootstrap-sprockets
//= require_tree .
//= require_self
Lastly my application.html.erb is this
<!DOCTYPE html>
<html>
<head>
<title>Squirm</title>
<%= stylesheet_link_tag "bootstrap" %>
<%= javascript_include_tag "bootstrap" %>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
<%= csrf_meta_tags %>
</head>
<body>
<%= render 'partials/navbar' %>
<div class="container">
<%= yield %>
</div>
</body>
</html>
Bootstrap seems to we working, but in the Google Chrome console seems not to be found
You're loading Bootstrap before you've loaded jQuery. Many of Bootstrap's components require javascript (carousel, tabs, etc.), however, most of Bootstrap will work without, which is why the Bootstrap CSS is showing on your page.
Loading Bootstrap after jQuery will fix the issue:
<!DOCTYPE html>
<html>
<head>
<title>Squirm</title>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
<%= stylesheet_link_tag "bootstrap" %>
<%= javascript_include_tag "bootstrap" %>
<%= csrf_meta_tags %>
</head>
<body>
<%= render 'partials/navbar' %>
<div class="container">
<%= yield %>
</div>
</body>
</html>
Also, not 100% sure based on your code, but you may be loading bootstrap twice. It seems this line: //= require bootstrap-sprockets is already loading Bootstrap.
you need to add jquery as well normally jquery come bundled in rails app, but maybe due to some reasons its not thr in your app
add
jquery from
https://cdnjs.com/libraries/jquery/
and let us knwo if this change works.
After reading http://chartkick.com/ I've tried to add chart to my website
Gemfile:
...
gem 'chartkick'
...
index.html.erb:
<%= javascript_include_tag "//www.google.com/jsapi", "chartkick" %>
<%= pie_chart({"Football" => 10, "Basketball" => 5}) %>
<h1>Hello, Rails!</h1>
assets/javascript/application.js:
//= require chartkick
//= require jsapi
//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require_tree .
But all I've got is:
undefined method `pie_chart' for #<#:0x4e49bd8>
I use chartkick (1.2.4), ruby(1.9.3), rails (4.1.0). What should I do?
I would need to look into chartkick further if this isn't the fix, but restart your Rails server and try again.
I had the same issue, for Chartkick to work I had to put the:
<%= javascript_include_tag "//www.google.com/jsapi", "chartkick" %>
in the the application.html.erb file only not the index file, under the head attribute
<head>
...
<%= javascript_include_tag "//www.google.com/jsapi", "chartkick" %>
</head>
And it was then usable in the whole application, we also found it to be more reliable when it was in the application.html.erb file.
here is mobile.js
//= require jquery
//= require iui
//= require faye-updater
//= require anonymous-chat
//= require anonymous-vote
//= require_self
here is how i include scripts
<%= content_for :head do %>
<%= javascript_include_tag "#{Settings.faye.address}/client.js" %>
<%= javascript_include_tag "mobile" %>
<% end %>
and what i get after recompiling assets: mobile....js starts from
function launch_faye_updater....
this is function from the faye-updater.js and it must be included after jquery and iui. And it does not work because of wrong inclusion order. How to make Rails include assets in right order ?
UPD: This is in production mode Rails 3.2.8
Where is launch_faye_updater being called from?
I'm guessing you can fix this problem by moving this line:
<%= javascript_include_tag "#{Settings.faye.address}/client.js" %>
Down below the other include, like so:
<%= javascript_include_tag "mobile" %>
<%= javascript_include_tag "#{Settings.faye.address}/client.js" %>
(You may also want to consider creating a new compiled JS file with these two files in it.)
I had the same problem with my jquery, bootstrap and application dependencies. You can deliver all your JS modules in preferred order in Rails 3.1+. In your example you want to have jquery.js included before mobile.js.
First, remove jquery from your mobile.js file.
Then you need to add following line of code to your application.rb:
config.assets.precompile += ['mobile.js', 'jquery.js', 'jquery_ujs.js']
At this moment you have everything precompiled and ready to use. Your mobile.js doesn't include jquery, so you can include it in your preferred order:
<%= javascript_include_tag "jquery" %>
<%= javascript_include_tag "mobile" %>
And that's it!
I have a Rails 3.1 application
In my gemfile:
gem 'jquery-rails', '>= 1.0.12'
In my assets/application.js, I have:
//= require jquery
//= require jquery_ujs
//= require_tree .
In my application.html layout, I've included these lines
<%= javascript_include_tag "application" %>
<%= javascript_include_tag "jquery.min" %>
I'm using jQuery v1.6.2.
The problem is, when I try to access any page, I keep getting these errors in the console:
Uncaught TypeError: Object function (selector,context){return new jQuery.prototype.init(selector,context);} has no method 'ajaxPrefilter' (:3000/assets/jquery_ujs.js?body=1:290)
Uncaught TypeError: Cannot read property 'setOffset' of undefined (:3000/assets/jquery-ui-1.8.18.custom.min.js?body=1:37)
Uncaught TypeError: Object function (a,b){return new jQuery.prototype.init(a,b)} has no method 'ajaxPrefilter' (application.js:12)
What is ajaxPrefilter, and how do I fix these errors?
I've tried to reorder the javascripts with loading jquery.min.js before application.js, no luck, and I'm not sure how to inspect those errors in the js files themselves.
Try this:
<%= javascript_include_tag "application" %>
<%= javascript_include_tag "http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" %>
<%= javascript_include_tag "http://code.jquery.com/ui/1.8.19/jquery-ui.min.js" %>
I'm using the assets pipeline from Rails 3.1 and I want to include some javascript files only if it's the development environment.
Example:
//= require application/jquery
//= require application/jquery_ujs
// next ones only for development environment
//= require application/badglobals
//= require application/consul
Its there a standar way of doing this? Any suggestions?
Update
Looking at the Sprockets current documentation, seems like there is not a way to do this.
Why not just require these in the view? Is it important that they are loaded in the asset? To load them in the view:
<% if Rails.env.development? %>
<%= javascript_include_tag "application/badglobals" %>
<%= javascript_include_tag "application/consul" %>
<% end %>
If you rename your application.js file (or whichever file you're calling //= require ... in) to application.js.erb, you can take advantage of require_asset. i.e:
//= require application/jquery
//= require application/jquery_ujs
<% if Rails.env.development? %>
<%= require_asset 'application/badglobals' %>
<%= require_asset 'application/consul' %>
<% end %>
