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.

FormBuilder helper for more usefully:
<%= 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.ckeditor :content, :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 your wont 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( = {})
ckeditor_filebrowser_scope()
end
def ( = {})
ckeditor_filebrowser_scope()
end
end
Callbacks
class ApplicationController < ActionController::Base
protected
# Cancan example
def ckeditor_authenticate
action_name, @asset
end
# Set current_user as assetable
def ckeditor_before_create_asset(asset)
asset.assetable = current_user
return true
end
end
