What is the equivalent to getLastInsertId() in Cakephp?

Question

If I do getLastInsertId() immediately after a save(), it works, but otherwise it does not. This is demonstrated in my controller:

f

Try using this code in your model class (perhaps in AppModel):

function get_sql_insert_id() {
   $db =& ConnectionManager::getDataSource($this->useDbConfig);
   return $db->lastInsertId();
}

Caveat emptor: MySql's LAST_INSERT_ID() function only works on tables with an AUTO_INCREMENT field (otherwise it only returns 0). If your primary key does not have the AUTO_INCREMENT attribute, that might be the cause of your problems.
