问题
i want to do model validation with association in a single form. i have two tables users(parent table) and user_details(child table).now model validation is working for users table only.i want it for userDetails table also. relation between them is hasOne.
validation working for only users table because i have created newEntity for users table only.
usersController.php (controller code)
public function add() {
$user = $this->Users->newEntity();
$userDetail = $this->UserDetails->newEntity();
if ($this->request->is('post')) {
$user = $this->Users->patchEntity($user, $this->request->getData());
if ($this->Users->save($user)) {
$userDetail = $this->UserDetails->patchEntity($userDetail, $this->request->getData());
$userDetail->user_id = $user->id;
if ($this->UserDetails->save($userDetail)) {
$this->Flash->success(__('The user has been saved.'));
} else {
$this->Flash->error(__('The user could not be saved. Please, try again.'));
}
$this->redirect($this->referer());
} else {
$this->Flash->error(__('The user could not be saved. Please, try again.'));
}
}
$this->set(compact('user','userDetail'));
}
UsersTable.php (parent model)
public function validationDefault(Validator $validator) {
$validator
->integer('id')
->allowEmpty('id', 'create');
$validator
->email('email')
->requirePresence('email', 'create')
->notEmpty('email');
$validator

->minLength('password', 4,'Minimum length should be 4 digits')
->requirePresence('password', 'create')

return $validator;
}

回答1:
validation working for only users table because i have created newEntity for users table only.
That has nothing to do with it. The problem is that you are not following the naming conventions properly.
Filenames must match classnames, so it's UserDetailsTable.php, not UserDetails.php, UsersTable.php, not usersTable.php, etc.
And the correct property name for a hasOne association, is the singular, underscored variant of the association name, so for UserDetails that would be user_detail, consequently the name for the related form control should be user_detail.name.

You're trying to patch your details entity with the wrong data ($this->request->getData()). But really, there is no need to create, patch and save a separate entity in your add function, because the first level of associations will be handled transparently for you. This should work just fine:
public function add() {
$user = $this->Users->newEntity();
if ($this->request->is('post')) {
$user = $this->Users->patchEntity($user, $this->request->getData());
if ($this->Users->save($user)) {
$this->Flash->success(__('The user has been saved.'));
return $this->redirect($this->referer());
} else {
$this->Flash->error(__('The user could not be saved. Please, try again.'));
}
}
$this->set(compact('user'));
}
Or, at least, it should once you correct the field names from the details entity to include "user_detail.", as @ndm said; your HTML above is still showing $this->Form->control('address',...) instead of $this->Form->control('user_detail.address',...), though it also includes fields for city and state, which aren't in your screen shot, so it's unclear what your current version might look like.
