Assign Value to rules

Hi folks

I have wanted to assign dynamic values to #__assets.rules.

Using beforestore, I grab my values as an assoc array in the form of :

action i.e. edit which holds an array of usergroup ids as key and value as value....

$array = (

  'edit' => array('234' => 1, '345' => 1, '456' => 1), 

  'delete' => array('12' => 1, '345' => 1, '678' => 1)
);

Then add this code:

// Establish DB connection
$db = JFactory::getDbo();
$query = $db->getQuery(true);

// then create your array, in the way you want to...
$arrayOfRules = ...do stuff to create array

// then assign array 
$config['storages']['#__content']['rules'] = $arrayOfRules;
