php - CodeIgniter activerecord, retrieve last insert id?

Question

Are there any options to get the last insert id of a new record in CodeIgniter?

$last_id = $this->db->insert('tablename',
    array('firstcolumn' => 'value',
    'secondcolumn' => 'value')
);

Considering the table consits of fields id (autoincrement) firstcolumn and secondcolumn.

This way you can use the insert id in the following code.

Shame on me...

I looked at the user guide and the first function is $this->db->insert_id();

This also works with activerecord inserts...
