Cakephp saveAll continuously giving Array to string conversion error - cakephp-2.0

Question

I am developing an Application using 2 models, Users and profiles.
when I am trying to editing both models at a time, I am getting continuously this error
Array to string conversion [CORE\Cake\Model\Datasource\DboSource.php, line 1006]
my $this->request->data array is in
array(
'User' => array(
'password' => '*****',
'id' => '6',
'first_name' => 'some',
'middle_name' => 'kjkj',
'last_name' => 'one',
'username' => 'kadjssa',
'group_id' => '5',
'mobile_no' => '7867868'
),
'Profile' => array(
'skype' => 'shrinet'
)
)
and my User controller edit function contain
public function editClient($id = null) {
$this->User->id = $id;
if (!$this->User->exists()) {
throw new NotFoundException(__('Invalid user'));
}
debug($this->request->data);
if ($this->request->is('post') || $this->request->is('put')) {
$this->request->data['User']['user_id'] = $this->Auth->User('id');
$this->request->data['Profile']['user_id'] = $id;
debug($this->request->data);
print_r (debug($this->User->invalidFields()));
if ($this->User->saveAll($this->request->data)) {
$this->Session->setFlash(__('The user has been saved'));
$this->redirect(array('action' => 'index'));
} else {
$this->Session->setFlash(__('The user could not be saved. Please, try again.'));
}
} else {
$this->request->data = $this->User->read(null, $id);
}
$groups = $this->User->Group->find('list');
$this->set(compact('groups'));
}
in debugging its giving
SQL Query: INSERT INTO `mvs`.`users` (`id`, `first_name`, `middle_name`, `last_name`, `username`, `password`, `group_id`, `mobile_no`, `user_id`, `modified`, `created`) VALUES (Array, Array, Array, Array, Array, Array, Array, Array, Array, '2013-07-05 00:07:13', '2013-07-05 00:07:13')
Please help me... thanks in advance

Answer 1

The docs recommend to use saveAssociated or saveMany depending on the case
This function receives the same options as the former two, and is generally a backwards compatible function. It is recommended using either saveMany or saveAssociated depending on the case
So the first choice is to change that saveAll to saveAssociated, since I think there's just one user and one profile.
All saveAll does is to call Set::numeric(array_keys($data)), and if that is true, calls saveMany, otherwise saveAssociated. The problem probably is in that Set::numeric comparison. If you want to get to the bottom of that, do a debug of
Set::numeric(array_keys($this->request->data));
If that gives you true, it must consider your array to be numerically indexed. Then you'll need to start debugging why is considered that way, check the Set::numeric function, where does the bad check, and change it or report it as a bug.
I think that trying to debug that is more troublesome than to change saveAll to saveAssociated, though, since you commented that the last gives you no problem.

Thank god,
I found resolution......
just use $this->User->saveAll($this->request->data, array('atomic' => false, 'deep' => true)); instead of $this->User->saveAll($this->request->data); because
Be careful when checking saveAssociated calls with atomic option set to false. It returns an array instead of boolean
