Problems with ckeditor running on production Rails application with Heroku

Question

I'm using the ckeditor gem in my Rails 4 application. Everything works great locally and on my staging heroku environment, but I get this errors when pushing on the production environment :

GET http://myapp.herokuapp.com/assets/ckeditor/contents.css 404 (Not Found)
GET http://myapp.herokuapp.com/assets/ckeditor/skins/moono/icons.png 404 (Not Found)

The editor shows up well, but all icons are missing.

I followed the README (https://github.com/galetahub/ckeditor), but I'm probably missing something.

Here are my steps:

1) Gem installation, generate etc ...

2) config.autoload_paths += %W(#{config.root}/app/models/ckeditor) in application.js

3) mount Ckeditor::Engine => "/ckeditor" in routes.rb (I don't understand why)

4) In application.js

//= require ckeditor/override
//= require ckeditor/init

What is this doing exactly, why is override needed ? (Where are located these files, because there are not in /app/assets, neither in /lib/assets neither in /vendor/assets)

Heroku is read only oriented, therefore I can't run the rake task as explained in the tutorial. And I think this is why I get the errors in production mode.

Did anyone faced the same problem ? I ran through all stackoverflow questions, but nothing resolved my problem so far.

UPDATE :

The only way I found out to make it works is the live compilation : config.assets.compile = true But I would prefer not to use this in production, and I don't understand why it does work.

Currently the solution for this problem has been changed.

There is no need to include "ckeditor/override.js"

1 Update your gem.

bundle update ckeditor

2 Add this line to your file config/application.rb

config.assets.precompile += Ckeditor.assets
config.assets.precompile += %w( ckeditor/* )
config.autoload_paths += %W(#{config.root}/app/models/ckeditor)

It works for me hope will work for you too.
