Cancan usage? about ckeditor

[galetahub]

Added support for cancan integration in this commit d336964

[galetahub]

Try this:

can [:index], Ckeditor::Picture if user.role? :user

Thanks for the suggestion. I had tried that before and unfortunately that doesn't work. I just get CanCan::AccessDenied when using that.

heres some lines from the stacktrace:

I had the same issue. I figured out that the @asset in the callback is Nil at some point. (Perhaps it creates a dummy asset as a placeholder for the upload link--just guessing.) Anyway, if you just skip the authorize! method if the @asset is Nil, then it works:

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

Also, be sure your ability.rb file uses the suggestion from galetahub above:

can [:index], Ckeditor::Picture if user.role? :user

or

can [:index], Ckeditor::Asset if user.role? :user

I ran into this error also.

For me what fixed it was removing #{Rails.root}/app/models/ckeditor from config.autoload_paths in application.rb
