Usually, the way this sort of thing is handled is to put the form in
the "add" view. This way, if the save fails, Cake can simply
re-display the form. If it succeeds, a redirect occurs.

Would it be possible to put a regular link in the "view" view that
pointed to controller::add_device()? You could append the
subscriber_id to the URL. Or, you could use a hidden field in a form
with a GET method.

So, things would look something lie this:

request:
/subscribers/view/:id

display:
the subscriber's info, plus link/form to add device

request:
/subscribers/add_device/:id

display:
the form

If the POST fails, you simply don't redirect and Cake will re-display
the same form, though with an error msg if you've set that up.
