I cannot get Angular to work with Rails asset pipeline. I have:
application.js
//= require angular
angular.module('myApp', [])
.config([function() {
console.log('In config.');
}]);
application.html.erb
<!DOCTYPE html>
<html>
<head>
<%= javascript_include_tag 'application' %>
</head>
<body ng-app="myApp"></body>
</html>
When I load the page I do not see the expected "In config" in the console. Where are no errors prompted, the source is loaded correctly. After refreshing the page two times, on the third load the console message does appear eventually.
If I replace <%= javascript_include_tag 'application' %> with simply <script src="/assets/application.js"></script>, the application does work as expected.
What am I missing here?

I'm new to web development, so I'm sorry if this is basic stuff. I'm not sure how to connect the code in my application.html.erb or crop.hmtl.erb to the actual files I downloaded. Specifically, I downloaded the files for Jquery UI and Jcrop(which is reliant on Jquery UI) and moved both of them into my application's vendor file (home/website/vendor). I then followed a Jcrop tutorial to install the plugin,but it doesn't work. I think my application isn't successfuly accessing one or both of the downloaded files. The Jcrop guide gave me a suggestion for what to put in my application.html.erb but said I might have to adjust the code according the actual paths. I don't know how to do this or even what to look up to research it. Can anyone help?
Application.html.erb: this is what the Jquery UI guide (http://learn.jquery.com/jquery-ui/getting-started/) told me to put
<!DOCTYPE html>
<html>
<head>
<title>Website</title>
<%= stylesheet_link_tag "application", media: "all", "data-turbolinks-track" => true %>
<%= javascript_include_tag "application", "data-turbolinks-track" => true %>
<%= csrf_meta_tags %>
<link rel="stylesheet" href="jquery-ui.min.css">
<script src="external/jquery/jquery.js"></script>
<script src="jquery-ui.min.js"></script>
</head>
This is what the Jcrop guide (http://deepliquid.com/content/Jcrop_Manual.html) suggested I put into my application.html.erb, but said I may have to adjust:
<script src="js/jquery.min.js"></script>
<script src="js/jquery.Jcrop.min.js"></script>
<link rel="stylesheet" href="css/jquery.Jcrop.css" type="text/css" />
crop.html.erb
<% content_for(:head) do %>
<%= stylesheet_link_tag "jquery.Jcrop" %>
<%= javascript_include_tag "jquery.Jcrop.min" %>
<script type="text/javascript" charset="utf-8">
$(function() {
$("#cropbox").Jcrop();
});
</script>
<% end %>
<%= image_tag #thing.avatar.url(:large), :id => "cropbox" %>
Asset files (such as Javascript and CSS) should go in their respective folders inside of app/assets. For instance, if you place your files at the following locations within your application:
assets/javascripts/jquery.Jcrop.min.js
assets/stylesheets/jquery.Jcrop.css
You can then reference these files within your application.html.erb file (or crop.html.erb, using content_for) using the rails asset helpers:
<%= stylesheet_link_tag "jquery.Jcrop" %>
<%= javascript_include_tag "jquery.Jcrop.min" %>
Additionally, there is a jcrop-rails-v2 which may make the inclusion of JCrop assets easier.
In a rails project, I want just use controller and model of rails application. For this purpose, I use angularjs. I put my angularjs file in assets/angular directory and I route url and set templates from app.js in angular. Know I deactive rails view by below code in application_controller.rb:
class ApplicationController < ActionController::Base
protect_from_forgery with: :exception
def index
render :layout => 'application', :nothing => true
end
end
config/routes.rb:
root to: 'application#index'
Know, when I run the server and project run on localhost:3000, my scripts don't load and <head> of html file is empty.
<html>
<head>
</head>
<body>
<pre style="word-wrap: break-word; white-space: pre-wrap;">
</pre>
</body>
</html>
This problem is about asset pipeline, and js don't load. How can I fixed this problem?
I have this code for angular:
asset/javascripts/angular/app.js.erb:
'use strict';
angular.module('app', ['ngResource'])
.config(['$routeProvider', function($routeProvider, $locationProvider) {
$routeProvider
.when('/', {controller: 'ForumIndexController', templateUrl: '<%= asset_path('templates/index.html') %>'})
.otherwise({redirectTo: '/'});
}
]);
view/layout/application.html.erb:
<!DOCTYPE html>
<html lang="en" ng-app="app">
<head>
<title>SimpleForum</title>
<%= stylesheet_link_tag "application", :media => "all" %>
<%= javascript_include_tag "application" %>
<%= csrf_meta_tags %>
</head>
<body>
<div class="container">
<div ng-view></div>
</div>
</body>
</html>
assets/javascripts/application.js:
//= require jquery
//= require jquery_ujs
//= require angular.min
//= require angular-resource.min
//= require ../angular/app
//= require_tree ../angular
How can I set rails application to load scripts?
Any Idea about fixed this problem?
I don't think you need the ../ infront of the angular folder, since it is at the same level as the manifest.
//= require angular/app
//= require_tree angular
Should be fine.
I'm trying to use Dojo Toolkit 1.8 instead JQuery in a Rails 3.2.8 web application, mainly due of the lack of a complete and visually uniform widget based on JQuery. Followed these steps:
Unzip dojo, dijit and dojox directories into app/assets/javascripts
Changed in application.js //= require_tree . to //= require_directory .
Edited application layout (Not unobtrusive yet... just to effect of testing)
views/layouts/application.html.erb
<!DOCTYPE html>
<html>
<head>
<title>Dojo</title>
<%= stylesheet_link_tag 'application' %>
<%= javascript_include_tag 'application' %>
<%= stylesheet_link_tag '/assets/dijit/themes/claro/claro.css' %>
<%= javascript_include_tag "dojo/dojo", :'data-dojo-config' => 'async: true' %>
<%= csrf_meta_tags %>
</head>
<body class='claro'>
<%= yield %>
<script>
require(["dojo/parser", "dojo/ready"], function(parser, ready) {
ready(function() {
parser.parse();
});
});
</script>
</body>
</html>
Created a controller named home and a template to the index action
views/home/index.html.erb
<input type="text" required="true" name="bday" id="bday" data-dojo-type="dijit/form/DateTextBox" value=<%= localize(Date.today - 21.days) %> />
<button id="button1" type="button" data-dojo-type="dijit/form/Button">Button 1</button>
Ok, Dijit works nice! But when I try to put some dojo code within a CoffeeScript file (assets/javascripts/home.js.coffee), a "ReferenceError: require is not defined" error message is raised on Firebug console. Sample code:
require ["dojo/domReady!"], () ->
alert('ok')
If I put a //= require dojo/dojo before the code above, it runs, but all dojo modules are loaded (not just domReady) and a "Error: defineAlreadyDefined" is raised on Firebug.
Is there any way to call the require function without having to reload the entire dojo.js or even access a dojo global variable?
Thanks
It was a slip of mine, I swapped the javascripts inclusion order. The correct is:
<%= stylesheet_link_tag '/assets/dijit/themes/claro/claro.css' %>
<%= javascript_include_tag "dojo/dojo", :'data-dojo-config' => 'async: true' %>
<%= stylesheet_link_tag 'application' %>
<%= javascript_include_tag 'application' %>
Dojo wasn't loaded yet when I was trying to require modules within the coffeescript file.
Thank you for your attention.
Im just looking for a little clarity to better my understanding of the Rails asset pipeline. I have placed my stylesheets and javascripts within app/assets/javascripts and app/assets/stylesheets. Now i am trying to get these views to render on my page but so far nothing is showing.. I wanted to see if someone could confirm if the following looks correct
In my layouts/application i have
<%= stylesheet_link_tag "fullcalendar" %>
<%= stylesheet_link_tag "application" %>
<%= javascript_include_tag "jquery.js" %>
<%= javascript_include_tag "jquery.rest.js" %>
<%= javascript_include_tag "rails.js" %>
<%= javascript_include_tag "application.js" %>
<!-- these are needed for the calendar. -->
<%= javascript_include_tag "jquery-ui-1.8.11.custom.min.js" %>
<%= javascript_include_tag "fullcalendar.js" %>
<%= javascript_include_tag "calendar.js" %>
And my index.html.erb looks like
<html>
<head>
<link href="/stylesheets/fullcalendar.css" media="screen" rel="stylesheet" type="text/css" />
<script type='text/javascript' src='/javascripts/jquery.js'></script>
<script type='text/javascript' src='/javascripts/fullcalendar.js'></script>
<script type='text/javascript' src='/javascripts/calendar.js'></script>
<script type='text/javascript' src='/javascripts/jquery-ui-1.8.9.custom.min.js'></script>
<script type='text/javascript' src='/javascripts/jquery.rest.js'></script>
Am I missing something or just being a real novice ( All constructive criticism welcome)
in Your layouts/application you just need this:
<%= javascript_include_tag "application" %>
<%= stylesheet_link_tag "application", media: "all" %>
and in app/assets/stylesheets/application.css
you just need:
*=require_self
*=require_tree .
and in app/assets/javascripts/application.js
//= require jquery
//= require jquery_ujs
//= require_tree .
And there's o need to include all the files
You'll have some problems in production if you include js files, to avoid it, you should add such files, ex: "fullcalendar.js" in config/production.rb, config.assets.precompile += %W(fullcalendar.js), and then run rake asset:precompile
You can see a quick overview in Ryan Bates Video: #279 Understanding the Asset Pipeline.

Both helped me a lot.
the system-created page http://localhost:3000/pages/home shows up fine. but when i change the content of the file home.html.erb and reload the page in the browser and view the source code, i see the content from my home.html.erb file gets added under the automatically created content. so basically there are two pages in the source code. anyone knows what causes that?
my application.html.erb:
<!DOCTYPE html>
<html>
<head>
<title>SampleApp</title>
<%= stylesheet_link_tag :all %>
<%= javascript_include_tag :defaults %>
<%= csrf_meta_tag %>
</head>
<body>
<%= yield %>
</body>
</html>
my home.html.erb
<!DOCTYPE html>
<html>
<head>
<title>Ruby on Rails Tutorial Sample App | Home</title>
</head>
<body>
<h1>Sample App</h1>
...
</body>
</html>
Your application.html.erb is fine, but home.html.erb is used to include only what's inside <body> tag. So, in your case it must contain only the
<h1>Sample App</h1>
...
part.
