View source for Adding ACL rules to your component

== Using JTable To Handle Action Control Saving and Loading ==
The JTable class has some built-in support for ACL, to use this you have to add one integer field in your table named 'asset_id'. This field will be used to perform action control for your object. Do not confuse this with the 'access' field, which is only for access permission (read side) as Joomla! separates other actions from read access.

Normally, we have to override the __construct() method in our descendant class. We may also override the check() method to validate our data before saving to the database. For ACL action support we have to override these methods:-

* <code>public function bind($array, $ignore = '')</code> to let JTable save rule data to Joomla's assets table.
* <code>protected function _getAssetName()</code> to give an asset name to our asset.
* <code>protected function _getAssetParentId($table = null, $id = null)</code> to give a parent id to our asset. Normally Joomla! uses root (1) as a parent. Generally we will change parent of node to our component. Doing all of these makes JTable handle storing and loading action control settings for us.
