Re: hasOne relationship problem
Looking through cake/libs/model/model.php I don't see anywhere in
saveAll where a check is done for a hasone association. (May have
missed it). I don't see how it could do this by default in any case.
It could recognize the hasone association but then how would it verify
uniqueness. It couldn't use the ID since that is unique for every
record. And it doesn't know which field to use to check uniqueness.
Since username should be unique I would say that you should add a
validate for isUnique for the username. This will prevent mulitiple
users with the same name and therefore enforce one profile per user.
in the User model add this:
var $validate = array(
'username' = => array(
'rule' => 'isUnique',
'message' => 'The user name has already been taken',
'required' => true));

Re: hasOne relationship problem
Thanks Paulos for your advice. I could certainly add some manual
checking before adding a child record. The question I am having in my
mind is that should duplicate check be done by the hasOne relationship
or is it possible. Am I missing anything here?

Re: hasOne relationship problem
Hi Robin.I am not an expert coz i am trying to build a similar app of yours
so i ll tell you my opinion.As i saw your tables format i think you should
set depentent=true in user model and the exslusive field in profile model
true.The 1st one will delete the associated profile if the user has been
deleted and the 2nd (i think) is what u search for.Alternatively , you can
set the add profile link to invisible when a user has already a profile so
that the rest CRUD functions can be shown.
