Using Zend Framework, I've created a Model to insert a record into a database. My question is, after $this->insert($data) how can I switch the active table so that I can insert a record into another table?

Here's my code so far:

class Model_DbTable_Foo extends Zend_Db_Table_Abstract
{
  protected $_name = 'foo';

  public function addFoo($params)
  {
    $data = array(
      'foo' => $params['foo'],
    );
    $this->insert($data);
    $foo_id = $this->getAdapter()->lastInsertId();

    $data2 = array(
      'bar' => $params['bar']
    );
    // I need to change the Db Table name here.
    $this->insert($data2);
    $bar_id = $this->getAdapter()->lastInsertId();
  }
}
