Class Method Details

.included(receiver) ⇒ Object

use the Plugin mixin to define your own custom plugins you want to mixin on your Deas view handlers. Define included hooks using ‘plugin_included`. this allows you to define multiple hooks separately and ensures the hooks will only be called once - even if your plugin is mixed in multiple times.
