In my layout footer I am including page specific JavaScript files like so:
<%= javascript_include_tag "#{params[:controller]}_#{params[:action]}" if javascript_exists?("#{params[:controller]}_#{params[:action]}") %>
The helper I am using is from another question on this site but modified to work with Rails 2:
application_helper.rb
def javascript_exists?(script)
script = "#{RAILS_ROOT}/public/javascripts/#{script}.js"
extensions = %w(.coffee .erb .coffee.erb) + [""]
extensions.inject(false) do |truth, extension|
truth || File.exists?("#{script}#{extension}")
end
end
Then I also init the included file:
<script>
jQuery(document).ready(function() {
<%= "#{params[:controller].titleize}#{params[:action].titleize}.init();" if javascript_exists?("#{params[:controller]}_#{params[:action]}") %>
});
</script>
This works perfectly fine if my file is named controller_action.js but once renamed to controller_action.js.erb Rails generates an error because it can't find it.
GET http://localhost:3000/javascripts/controller_action.js 404 (Not Found)
Uncaught ReferenceError: ControllerAction is not defined
Update
If I use the .rjs extension then there are no errors generated but this seems to be because Rails doesn't think the file exists. (I updated the javascript_exists? with the .rjs extension.)
After some more debugging, the file is being located:
/path/public/javascripts/circuit_list.js true
but this returns false if .rjs is used.
The routing error when navigating to http://localhost:3000/javascripts/controller_action.js in the browser is:
No route matches "/javascripts/controller_action.js" with {:method=>:get}

importmap.rb includes
pin "javascript-autocomplete", to: "https://ga.jspm.io/npm:javascript-autocomplete#1.0.5/auto-complete.js"
And, following the rails guides, application.js was amended with
import "javascript-autocomplete"
although uncertainty about the syntax remains. Also attempted, as the script defines var autoComplete was
import autoComplete from "javascript-autocomplete"
in either instance, while the header shows:
<script type="importmap" data-turbo-track="reload">{

the body has
<%= javascript_tag do %>
var demo1 = new autoComplete({

which fails to run: Uncaught ReferenceError: autoComplete is not defined
so the script is not being accessed.
So where is this lacking?
I'm using this tutorial to try to facilitate image uploads using the TinyMCE WYSIWYG editor on my rails 5.2 app.
So far I have implemented all the code in the tutorial and everything works perfectly, but when I try to upload an image I get a "Got a bad response from the server" error message.
In my heroku logs I then get this:
FATAL -- : [527c4468-9ebe-475a-97a9-380bfc327aab] ActionController::RoutingError (uninitialized constant #<Class:0x000055b6d991e020>::EditController
2020-02-22T17:34:07.814727+00:00 app[web.1]: Did you mean? DeviseController):
Here is the route I'm using:
post '/tinymce_assets', to: 'article/edit#image_upload'
With these controller methods:
def image_upload
file = params[:file]
url = upload_file(file)
render json: {
image: {
url: url
}
}, content_type: "text/html"
end
private
def upload_file(file)
s3 = Aws::S3::Resource.new(region:ENV['AWS_REGION'])
obj = s3.bucket(ENV['S3_BUCKET_NAME']).object('articles/images/content/' + filename(file))
obj.upload_file(file.tempfile, {acl: 'public-read'})
obj.public_url.to_s
end
def filename(file)
file.original_filename.gsub(/[^a-zA-Z0-9_\.]/, '_')
end
And this to initialize it:
<%= f.text_area :body, class: "tinymce", rows: 20, cols: 120 %>
<%= tinymce :content_css => asset_path('application.css')%>
...
<script>
$(document).ready(function() {
tinymce.init({
selector: "textarea.tinymce", // change this value according to your HTML
});
});
</script>
Can anyone see where I'm going wrong here?
Rails is trying to find an EditController because of your route: post '/tinymce_assets', to: 'article/edit#image_upload'
This route suggests that the controller it should look in is Article::EditController. Since you are actually looking for the ArticlesController you should change your route to be:
post '/tinymce_assets', to: 'articles#image_upload'
The Rails routing documentation can be helpful, specifically section 2.2 and 2.6. https://guides.rubyonrails.org/routing.html
I'm following along with the Angular/Rails tutorial at Thinkster and I've run into an issue which seems to be most likely be Angular-related. Everything works just fine until I get to the Angular Routing section. Simply put, the inline templates within the <script> tags do not load in the <ui-view></ui-view> element. I originally thought this may be due to having opened the page locally as a file rather than having it loaded from a server, but the same problem persists even after integrating Rails (using an older version of Sprockets, as pointed out in this similar but unrelated issue).
When I load the index page in either the browser as a file or as a URL when running the Rails server, I've inspected the HTML and, sure enough, the only thing it shows in the code are the divs and an empty <ui-view> element, indicating something just isn't adding up correctly. I've tried various things, including:
Using the newest version of ui-router (0.2.15 at this writing) rather than the version in the tutorial
Using <div ui-view></div> instead of <ui-view></ui-view>
Changing the value of 'url' in the home state to 'index.html', including using the full path to the file (file:///...)
Putting the contents of the inline <script> templates into their own files (without the <script> tags, of course) and specifying the 'templateUrl' field using both relative and full paths
Trying both Chrome and Firefox just to be extra certain
None of these things have worked, even when accessing http://localhost:3000/#/home when the Rails server is running after having integrated Angular into the asset pipeline in the Integrating the Front-end with the Asset Pipeline section of the tutorial. Indeed, the route loads but does not show anything more than a completely blank page with a lonesome and empty <ui-view> element when inspecting the HTML using Chrome's dev tools.
Given that the issue seems to occur even before the Rails portion, it does seem like something to do with Angular itself, but I've got no clue what's going on, especially since I've followed along to the letter.
I'm using Bower to manage the Angular dependencies and the HTML does show that the Angular javascript files in both the app/assets/javascripts directory and in the vendor/assets/bower_components directory are being loaded properly in the <head> section, so everything seems to be okay on the asset pipeline integration.
Versios I'm using:
Rails: 4.2.3
Ruby: 2.2.1p85
Angular: 1.4.3
ui-router: 0.2.15

});
};
return o;
}]);
If any other code is required to help uncover the problem, please let me know and I'll supply anything requested.
it seems that the angular-ui-router is incompatible with the new Rails sprockets. To fix this, add this earlier version of sprockets to your gemfile:
gem 'sprockets', '2.12.3'
And then run bundle update sprockets.
This was answered a few times in other similar questions, like the one below:
Angular Rails Templates just not working
$urlRouteProvider in my code should've been $urlRouterProvider. Be sure to double-check everything, folks, and make good use of the console!
I'm porting my symfony app to Ruby on Rails 4.2.0. My setup works fine in symfony. There is this old post on how to use dojo with RoR, but it uses deprecated code.
In my application.html.erb I have
<script>dojoConfig = {async: true}</script>
<%= javascript_include_tag 'http://ajax.googleapis.com/ajax/libs/dojo/1.10.3/dojo/dojo.js'%>
I replaced the symfony wrappers with Rails ones. I also changed the dojo version. I was using 1.9.1. Rails generates this html:
<script>
dojoConfig = {async: true}
</script>
<script src="http://ajax.googleapis.com/ajax/libs/dojo/1.10.3/dojo/dojo.js">
The last line is followed by a bunch of compressed javascript and the close script tag in Firebug.
I didn't make any changes in my home/index.html.erb where I'm testing this code. In app/assets/javaascipts/home.js, I have:
//require(["dojo/dom", "dojo/ready", "dijit/Tooltip"], function(dom, ready, Tooltip)
define(["dojo/dom", "dojo/ready", "dijit/Tooltip"], function(dom, ready, Tooltip)
{
ready(function()
{
var head = "<div class='footnote-text'>";
var tail = "</div>";
var fnt1 = head + dom.byId("fnb1").innerHTML + tail;
var fnt2 = head + dom.byId("fnb2").innerHTML + tail;
var fnt4 = head + dom.byId("fnb4").innerHTML + tail;
new Tooltip({ connectId: ["footnote1"],position:["after","above","below"],label: fnt1 });
new Tooltip({ connectId: ["footnote2"],position:["after","above","below"],label: fnt2 });
new Tooltip({ connectId: ["footnote4"],position:["after","above","below"],label: fnt4 });
new Tooltip({ connectId: ["footnote5"],position:["after","above","below"],label: fnt4 });
});
});
//require(["dojo/dom", "dojo/ready", "dijit/Dialog"], function(dom, ready, Dialog){
define(["dojo/dom", "dojo/ready", "dijit/Dialog"], function(dom, ready, Dialog){
ready(function(){
var fnt3 = dom.byId("fnb3").innerHTML;
myDialog = new Dialog({
title: "Contact Me",
content: fnt3,
style: "width: 300px"
});
});
});
The commented out require lines are what I use in my symfony app. As you can see, I replaced them with define as described on the dojo site. When I run it, I get the following error on the Firebug console:
ReferenceError: define is not defined
...define(["dojo/dom", "dojo/ready", "dijit/Tooltip"], function(dom, ready, Tooltip
If I used require instead of define, I get require is not defined.
Update
I tried installing dojo into the app and made some progress. I copied the download from dojo to vendor/assets/javascript/dojo. The dojo directory contains the subdirectories dojo, dojox, and digit
I then added
//= require dojo/dojo/dojo.js
to app/assets/javascript/application.js. I also changed the define back to require in the home.js file. When I reloaded the page, I got an error complaining that it couldn't find Tooltip. I then added:
//= require dojo/dijit/Tooltip.js
On reload it complained about a bunch of other missing js files. This is the same problem I had using symfony, which is why I went to the google image. How can I get to rails to search for the files in the vendor directories? This is one of the errors:
"NetworkError: 404 Not Found - http://amcolan.loc/dijit/_base/manager.js"
Update 2
Since require_tree worked for app assets, I thought it might work to vendor as well. I added
//= require_tree ../../../vendor/assets/javascripts/dojo
to my application.js file. When I reloaded the page, it took about a minute. My guess is that it's loading everything in the dojo directory tree, which is not surprising. The page load completed without any errors. When I hovered over a tooltip item (the purpose of the code is to show tooltips), Firebug cranked out about two thousand errors and quit. All the errors appear to be "ReferenceError: define is not defined"
Update 3
I went back to using the googleapi. My application.html.erb header looks like this
<head>
<meta charset="UTF-8">
<title><%= content_for?(:title) ? yield(:title) : "American Colonial Ancestors" %></title>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<script>dojoConfig = {async: true}</script>
<%= javascript_include_tag 'http://ajax.googleapis.com/ajax/libs/dojo/1.10.3/dojo/dojo.js'%>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
<%= csrf_meta_tags %>
</head>
I reversed the order of the javascript includes. The page reloaded without errors. The tooltip doesn't work, but it doesn't generate any errors when I hover over an item. I put a bad statement in the home.js code and it came up on the console so I know the code is being parsed. I may just have a bug in my page setup.
There may be more than one way to get Dojo toolkit to work with Ruby on Rails. This is the easiest if not the most efficient way. This works in Rails 4.2.0. I would imagine it would work in other versions as well.
In views/layouts/application.html.erb add the following prior to the inclusion of the site scripts:
<script>dojoConfig = {async: true}</script>
<%= javascript_include_tag 'http://ajax.googleapis.com/ajax/libs/dojo/1.10.3/dojo/dojo.js'%>
Change the version to the latest or to which ever one you want to use. Here I'm using version 1.10.3. The dojo site says there are other CDN's (Content Delivery Network) for the source code. I'm using google as it was in their example. Here are the pertinent parts of my head section:
<head>
<meta charset="UTF-8">
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<%= stylesheet_link_tag "http://ajax.googleapis.com/ajax/libs/dojo/1.10.3/dijit/themes/claro/claro.css" %>
<script>dojoConfig = {async: true}</script>
<%= javascript_include_tag 'http://ajax.googleapis.com/ajax/libs/dojo/1.10.3/dojo/dojo.js'%>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
<%= content_for :page_script %>
<%= csrf_meta_tags %>
</head>
If you are going to use any of the toolkit's dialog boxes, tooltips, etc, you will need to include a stytlesheet by adding something like this:
<%= stylesheet_link_tag "http://ajax.googleapis.com/ajax/libs/dojo/1.10.3/dijit/themes/claro/claro.css" %>
Change the version and the theme to your own requirements. Here I'm using the claro theme. You can see it in my head section above. I don't think placement is critical. You also need to declare your theme class in the body statement. Here's mine:
<body class="claro">
An older post on the subject had different javascript formatting. I don't think anything special is needed. Here's an example of a working script:
require(["dojo/dom", "dojo/ready", "dijit/Tooltip"], function(dom, ready, Tooltip)
{
ready(function()
{
var head = "<div class='footnote-text'>";
var tail = "</div>";
var fnt1 = head + dom.byId("fnb1").innerHTML + tail;
var fnt2 = head + dom.byId("fnb2").innerHTML + tail;
new Tooltip({connectId: ["footnote1"], position:["after","above","below"], label: fnt1 });
new Tooltip({connectId: ["footnote2"], position:["after","above","below"], label: fnt2 });
});
});
As mentioned in my question, I tried placing the Dojo Toolkit source in vendor/assets/javascript. Starting with with version 1.7, dojo started using Asynchronous Module Definition (AMD). It may be the case that the AMD loader is incompatible with the Rails pre-compile feature. I don't know enough about it to say for sure.
I cannot get the galetahub ckeditor gem to work with Rails 4 for me. I searched for any problems online but cannot find any. I'm following the instructions exactly.
I include gem "ckeditor" in my Gemfile
I include gem "carrierwave" and gem "mini_magick"
I run rails generate ckeditor:install --orm=active_record --backend=carrierwave
I run rake db:migrate
Inside application.rb I include config.autoload_paths += %W(#{config.root}/app/models/ckeditor)
Inside routes.rb I have mount Ckeditor::Engine => '/ckeditor'
I'm using SimpleForm so I paste the following ERB <%= f.input :description, as: :ckeditor %> in my view.
And I think that's it. But my text area does not convert to a CKeditor area for some reason.
STEP 1: Add gem 'paperclip' and gem "ckeditor" in your gemfile.
STEP 2: Bundle Install.
STEP 3: rails generate ckeditor:install --orm=active_record --backend=paperclip
STEP 4: Place config.autoload_paths += %W(#{config.root}/app/models/ckeditor) in application.rb
STEP 5: Place mount Ckeditor::Engine => "/ckeditor" if not present in routes.rb already and run db:migrate
STEP 6: Open application.html.erb and place this <%= javascript_include_tag 'ckeditor/ckeditor.js' %> in header.
STEP 7: Place this in footer(above the body tag) in application.html.erb
<script type="text/javascript">$(document).ready(function() {
if ($('textarea').length > 0) {
var data = $('textarea');
$.each(data, function(i) {
CKEDITOR.replace(data[i].id);
});
}
});</script>
STEP 8: Restart the WEBrick SERVER.
That's it.
Else
Download the CKEditor Zip file, extract the files and place them in the sub directory “javascripts/ckeditor”, add the main JS file to the layout..
javascript_include_tag 'ckeditor/ckeditor.js'
Place this in footer(above the body tag) in application.html.erb
<script type="text/javascript">$(document).ready(function() {
if ($('textarea').length > 0) {
var data = $('textarea');
$.each(data, function(i) {
CKEDITOR.replace(data[i].id);
});
}
});</script>
I have the same problem using rails 4 and apparently the problem is that the form helper
form.cktext_area
Or in your case
f.input :description, as: :ckeditor
it's not generating what it supposed to generate, and you don't have to load the editor manually, the only thing you need to do is to is to add the class 'ckeditor' to your textarea and it will load automatically, like this:
f.cktext_area :body, :class => 'ckeditor'
Meanwhile the Galetahub gem has been updated, but it has to be updated in your app manually. Read the github page: https://github.com/galetahub/ckeditor.
ajkumar basically answered the question well already, but if you are still lost, all you need to do is download the js file, include it in your html, have a script snippet included in the HTML to activate ckeditor on a certain textarea tag ID, and then change the class of the "textarea" tag you want to change to ckeditor. Quick sample below
<!DOCTYPE html>
<html>
<head>
<title>A Simple Page with CKEditor</title>
<!-- Make sure the path to CKEditor is correct. -->
<script src="../ckeditor.js"></script>
</head>
<body>
<form>
<textarea name="editor1" id="editor1" rows="10" cols="80">
This is my textarea to be replaced with CKEditor.
</textarea>
<script>
// Replace the <textarea id="editor1"> with a CKEditor
// instance, using default configuration.
CKEDITOR.replace( 'editor1' );
</script>
</form>
</body>
</html>
The galetahub gem is currently broken on Rails 4. This one is working fine though: https://github.com/tsechingho/ckeditor-rails
In case you are having trouble making it work with active admin, make sure to put this:
config.register_javascript 'ckeditor/ckeditor.js'
config.register_javascript 'ckeditor/init.js'
Into config/initializers/active_admin.rb
