# CKEditor for rails asset pipeline

[CKEditor](http://ckeditor.com/) is a library for WYSIWYG editor to be used inside web pages.

The `ckeditor_rails` gem integrates the `CKEditor` with the Rails asset pipeline.

And it would work with following environments:

* ruby 1.9.3+
* rails 3.0+

## Basic Usage

### Install ckeditor_rails gem

Include `ckeditor_rails` in Gemefile

    gem 'ckeditor_rails'

Then run `bundle install`

### Include CKEditor javascript assets

Add to your `app/assets/javascripts/application.js` after `//= require jquery_ujs` to work with jQuery

    //= require ckeditor-jquery

### Modify form field for CKEditor

Add `ckeditor` class to text area tag

    <%= f.text_area :content, :class => 'ckeditor' %>


### Initialize CKEditor in Javascript file

    $('.ckeditor').ckeditor({
      // optional config
    });

### Deployment

Since version 4.1.3, non-digested assets of `ckeditor-rails` will simply be copied after digested assets were compiled.

Eric Anderson, thanks.

## Advanced Usage

### Include customized configuration javascript for CKEditor

Add your `app/assets/javascripts/ckeditor/config.js.coffee` like

    CKEDITOR.editorConfig = (config) ->
      config.language = "zh"
      config.uiColor = "#AADC6E"
      true

### Include customized CKEDITOR_BASEPATH setting

Add your `app/assets/javascripts/ckeditor/basepath.js.erb` like

    <%
      base_path = ''
      if ENV['PROJECT'] =~ /editor/i
        base_path << "/#{Rails.root.basename.to_s}/"
      end
      base_path << Rails.application.config.assets.prefix
      base_path << '/ckeditor/'
    %>
    var CKEDITOR_BASEPATH = '<%= base_path %>';

### Include customized stylesheet for contents of CKEditor

Add your `app/assets/stylesheets/ckeditor/contents.css.scss` like

    body {
      font-size: 14px;
      color: gray;
      background-color: yellow;
    }
    ol,ul,dl {
      *margin-right:0px;
      padding:4 20px;
    }

## Gem maintenance

Maintain `ckeditor_rails` gem with `Rake` commands.

Update origin CKEditor source files.

    rake update_ckeditor VERSION=4.4.6

Publish gem.

    rake release

## Troubleshooting

#### CKEditor only loading after page refresh

This is due to interference with Turbolinks -

The problem stems from the link itself so in order to resolve this issue you must disable turbolinks in the div containing the link pointing to where CKEditor is.

You can visit the Rails Turbolinks Repo for detailed documentation
https://github.com/rails/turbolinks/#opting-out-of-turbolinks

**Example**

    <div class="example" data-no-turbolink>
    ...
    </div>
