Ckeditor

CKEditor is a text editor to be used inside web pages. It’s a WYSIWYG editor, which means that the text being edited on it looks as similar as possible to the results users have when publishing it. It brings to the web common editing features found on desktop editing applications like Microsoft Word and OpenOffice.

Features

• Rails 3.2 integration

• Files browser

• HTML5 files uploader

• Hooks for formtastic and simple_form forms generators

• Extra plugins: attachment and embed.

• Assets pagination (under construction)

Install

Rails 3.2:

gem "ckeditor", "3.7.1"

Rails <= 3.0:

gem "ckeditor", "3.6.3"

Now generate models for store uploading files

ActiveRecord + paperclip

For active_record orm is used paperclip gem (it’s by default).

gem "paperclip"

rails generate ckeditor:install --orm=active_record --backend=paperclip

ActiveRecord + carrierwave

gem "carrierwave"
gem "mini_magick"

rails generate ckeditor:install --orm=active_record --backend=carrierwave

Mongoid + paperclip

gem 'mongoid-paperclip', :require => 'mongoid_paperclip'

rails generate ckeditor:install --orm=mongoid --backend=paperclip

Mongoid + carrierwave

gem "carrierwave-mongoid", :require => 'carrierwave/mongoid'
gem "mini_magick"

rails generate ckeditor:install --orm=mongoid --backend=carrierwave

Available orms:

• active_record

• mongoid (Thanks Dmitry Lihachev github.com/lda)

• mongo_mapper (under construction)

Autoload ckeditor models folder (application.rb):

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

Usage

Mount engine in your routes (config/routes.rb):

mount Ckeditor::Engine => "/ckeditor"

Procompile ckeditor js and css files (config/environments/production.rb):

config.assets.precompile += Ckeditor.assets

Include ckeditor javascripts rails 3.2:

//= require ckeditor/init

or

<%= javascript_include_tag "ckeditor/init" %>

Rails <= 3.0:

<%= javascript_include_tag :ckeditor %>

Form helpers:

cktext_area_tag("test_area", "Ckeditor is the best")

cktext_area_tag("content", "Ckeditor", :input_html => {:cols => 10, :rows => 20}, :toolbar => 'Easy')

• input_html - Options for text_area tag, others for ckeditor javascript configuration.

• language - appends automatically, by default it’s I18n.locale

• available ckeditor options - docs.cksource.com/ckeditor_api/symbols/CKEDITOR.config.html

In order to configure the ckeditor default options, create files:

app/assets/javascripts/ckeditor/config.js

app/assets/javascripts/ckeditor/contents.css

Here’s a FormBuilder helper example:

<%= form_for @page do |form| -%>
  ...
  <%= form.cktext_area :notes, :toolbar => 'Full', :width => 800, :height => 400 %>
  ...
  <%= form.cktext_area :content, :input_html => { :value => "Default value" } %>
  ...
  <%= cktext_area :page, :info %>
<% end -%>

AJAX

jQuery sample:

<script type='text/javascript' charset='UTF-8'>
  $(document).ready(function(){  
    $('form[data-remote]').bind("ajax:before", function(){
      for (instance in CKEDITOR.instances){
        CKEDITOR.instances[instance].updateElement();
      }
    });
  });
</script>

Formtastic integration

<%= form.input :content, :as => :ckeditor %>
<%= form.input :content, :as => :ckeditor, :input_html => { :height => 400 } %>

SimpleForm integration

<%= form.input :content, :as => :ckeditor, :label => false, :input_html => { :toolbar => 'Full' } %>

Default scope

For example, you need split assets collection for each user.

class ApplicationController < ActionController::Base

  protected

    def ckeditor_filebrowser_scope(options = {})
      super({ :assetable_id => current_user.id, :assetable_type => 'User' }.merge(options))
    end
end

If you want to filter only pictures or attachment_files - redefine methods “ckeditor_pictures_scope” or “ckeditor_attachment_files_scope” respectively. By default, both these methods call “ckeditor_filebrowser_scope” method:

class ApplicationController < ActionController::Base

  protected

    def ckeditor_pictures_scope(options = {})
      ckeditor_filebrowser_scope(options)
    end

    def ckeditor_attachment_files_scope(options = {})
      ckeditor_filebrowser_scope(options)
    end
end

Callbacks

class ApplicationController < ActionController::Base

  protected

    # Cancan example
    def ckeditor_authenticate
      authorize! action_name, @asset
    end

    # Set current_user as assetable
    def ckeditor_before_create_asset(asset)
      asset.assetable = current_user
      return true
    end
end

I18n

en:
  ckeditor:
    page_title: "CKEditor Files Manager"
    confirm_delete: "Delete file?"
    buttons:
      cancel: "Cancel"
      upload: "Upload"
      delete: "Delete"
