That would work except that you're expecting that $id will always be
present in the URL. So you'll need to make sure it is (in links or
form actions). Or, you could change it to:
if (!$id || empty($this->data['ModelName']
['some_var_from_other_view']))
But that would still allow someone to access this method without going
to the other view. So, maybe:
if (empty($this->data['ModelName']['some_var_from_other_view']))
That's edit() not add() btw (not that it matters).

$this->redirect(array('controller' => 'the_other_controller', 'action'
=> 'index'));
