Asset management

In some cases you want your database records to have a special set of permissions which can override those set for the entire component in its Options. This is especially important if you are using the Joomla Categories, in which case your items may belong to a category, which belongs in another category, which belongs in another category… This cascading of permissions is made easy with Joomla's assets management.

To enabled assets management in your table you need to have an asset_id column in your database table. This sets $this->_trackAssets = true when your table object is constructed (no need to do it manually).

Moreover, you MAY have to override the _getAssetParentId, _getAssetName and _getAssetTitle methods if your items described by this table class belong in categories. Look at \Joomla\CMS\Table\Content to understand what is going on.

Finally, your bind() method needs to be overwritten so you can call the $this->setRules() method against the raw, JSON-encoded permissions data stored in the database table. Saving rules is automatic; you don't have to handle it yourself.
