I have tried figuring this out on my own to no avail.
Where do I validate data being saved into a HABTM table? I have
USERS:
id
SYSTEMS:
id
name
USERS_SYSTEMS:
id
user_id
system_id
I created a simple form for the User to update their Systems but where is
validation for this? Do I validate system_id in system model? Do I make a
user_systems model and set a validation rule for system_id and user_id
there? There is no system_id in the system model so it makes no sense to me
to put it in there. I made a user_systems model and put
var $validate = array(
'system_id' => array('rule' => array('minLength', 8)) //min 8 just to
check if it works as there are only single digit values in db
);
but it still saves so I am at a loss....
Can someone point out what model do I use to validate the HABTM data being
saved to the HABTM table?
thanks
Dave
