CakePHP load model validation rule not working - validation

Question

I am loading a model in different controller.
Controller name in which I am loading different model is - "MembersController" and I am loading "Usermgmt" Model of "UsermgmtController".
"Usermgmt" Model has validation as following-
public $validate = array(
'email' => array(
'valid' => array(
'rule' => 'notEmpty',
'required' => true,
'allowEmpty' => false,
'message' => 'Please enter a value for email.'
),
'duplicate' => array(
'rule' => 'isUnique',
'on' => 'create',
'message' => 'This email is already exist.'
),
'duplicate1' => array(
'rule' => 'email',
'message' => 'Please enter valid email.'
)
),
'firstname' => array(
'valid' => array(
'rule' => 'notEmpty',
'required' => true,
'allowEmpty' => false,
'message' => 'Please enter a value for first name.'
)
),
'username' => array(
'valid' => array(
'rule' => 'notEmpty',
'required' => true,
'allowEmpty' => false,
'message' => 'Please enter a value for user name.'
),
'duplicate' => array(
'rule' => 'isUnique',
'on' => 'create',
'message' => 'This user is already exist.'
)
),
'password' => array(
'valid' => array(
'rule' => 'notEmpty',
'required' => true,
'allowEmpty' => false,
'message' => 'Please enter a value for password.'
)
),
'confirm_password' => array(
'valid' => array(
'rule' => 'notEmpty',
'required' => true,
'allowEmpty' => false,
'message' => 'Please enter a value for confirm password.'
),
'duplicate2' => array(
'rule' => 'matchpassword',
'on' => 'create',
'message' => 'Password must be same.'
)
)
);
And now I am applying and loading model in following way.
$this->loadModel('Usermgmt');
$this->Usermgmt->set($this->data);
if ($this->Usermgmt->validates()) {
if ($this->Usermgmt->save($data, true)) {
$userid = $this->Usermgmt->id;
$this->Session->setFlash('User has been added', 'success');
}
}
But validation are not working and it is inserting empty values.

Answer 1

try uses to load model
Example :
public $uses = array('Usermgmt');

Answer 2

You are using two different instances of $data. namely $this->data and $data
You should be validating the same set of data you want to save, like either of the two following examples, whichever holds your data.
$this->loadModel('Usermgmt');
$this->Usermgmt->set($data);
if ($this->Usermgmt->validates()) {
if ($this->Usermgmt->save($data, true)) {
$userid = $this->Usermgmt->id;
$this->Session->setFlash('User has been added', 'success');
}
}
Or
$this->loadModel('Usermgmt');
$this->Usermgmt->set($this->data);
if ($this->Usermgmt->validates()) {
if ($this->Usermgmt->save($this->data, true)) {
$userid = $this->Usermgmt->id;
$this->Session->setFlash('User has been added', 'success');
}
}

Answer 3

Unless you are requiring to do some other logic after validation and before saving you could do away with explicitly calling validates() and just save the data as save() will automatically validate the data for you. Also, I've noticed you are using $this->data, it looks like you are using CakePHP 2 in which case you need to use $this->request->data instead:-
$this->loadModel('Usermgmt');
if ($this->Usermgmt->save($this->request->data) !== false) {
$this->Session->setFlash('User has been added', 'success');
}
If this still fails then make sure you are not overriding beforeValidate() in your model in a way that would cause validation to break.
