In the controller, where you are displaying the view with the option
to add a profile, do:
1) Count the number of profiles belonging to the user!
$profileCount = $this->User->Profile->find('count', array('conditions'
=> array('Profile.user_id' => $this->Auth->user('id') ) ) );
2) Pass the profile count to the view
$this->set('profileCount', $profileCount);
In the view, do:
1) Display the add option as disabled, if the profile count is 1
2) Display the add option as enabled, if the profile count is 0.
You still have to make sure that a new profile is not added in the add
action, as users can submit your form, disregarding your disabled add
option. So check also for the number of profiles there!
Enjoy,
John
