CakePHP - 保存失败；验证错误为空

Question

所以，我有这个方法来保存模型及其关联模型。它有验证规则，但没有针对导致错误的字段。

传递给 save 方法的数据正常，使用 atomic = false 的 save 方法的返回值在每个字段上都是 true，除了两个不具有任何验证。

saveAll/saveAssociated 失败，$this->Model->validationErrors 返回的是未验证为空数组的字段列表。

我已经在网上搜索过这个问题，并在 StackOverflow 上发现了与我类似的问题，但答案并没有解决我的问题。

这是代码。其余模型都可以，这里就不贴了。

**Add Method**

public function add() {
    if ($this->request->is('post')) {
        if(empty($this->request->data['User']['referer'])) {
            $this->request->data['Partner']['status'] = 1;
            $this->request->data['User']['group_id'] = 2;
            $this->request->data['User']['status'] = 1;
            $this->request->data['Customer']['birthday'] = implode("-", array_reverse(explode("/", $this->request->data['Customer']['birthday'])));
            $this->request->data['Customer']['newsletter'] = ($this->request->data['Customer']['newsletter'] == "1") ? true : false;
            $this->request->data['Customer']['accept'] = ($this->request->data['Customer']['accept'] == "1") ? true : false;

            if(!$this->request->data['Customer']['accept']) {
                $this->Session->setFlash(__('You must accept the terms and conditions to proceed.'), 'danger');
            } else {
                $this->Customer->Partner->create();
                var_dump($this->Customer->Partner->saveAssociated($this->request->data, array('atomic' => false)));
                debug($this->Customer->Partner->validationErrors);
                exit();
                if($this->Partner->saveAll($this->request->data)) {
                    $this->Session->setFlash(__('Your profile has been saved. Welcome to Abaixo da Tabela.'), 'success');
                    $this->redirect(array('controller' => 'pages', 'action' => 'display', 'home', 'admin' => false));
                } else {
                    $this->Session->setFlash('Ocorreu um erro ao tentar salvar seu perfil. Verifique se os campos estão preenchidos corretamente e tenta novamente.', 'danger');
                }
            }
        }
    }
}

** debug($this->Customer->Partner->validationErrors) **
array (size=5)
'Partner' => boolean true
'Address' => 
    array (size=7)
        'zip' => boolean true
        'address' => boolean true
        'number' => boolean true
        'adjunct' => boolean false
        'district' => boolean true
        'uf' => boolean true

        'password' => boolean true
        'password_confirm' => boolean true
        'group_id' => boolean true
        'status' => boolean true
'Customer' => 
    array (size=4)
        'genre' => boolean true
        'birthday' => boolean true
        'newsletter' => boolean false
        'accept' => boolean true

请注意 save 方法返回中的两个错误响应。

OP 写道:

Turned out that the error was in the view. The form fields for the associated models were like:

echo $this->Form->input('Customer.birthday')
echo $this->Form->input('Customer.newsletter')
echo $this->Form->input('Customer.accept')

When the correct way was:

echo $this->Form->input('Customer.0.birthday')
echo $this->Form->input('Customer.0.newsletter')
echo $this->Form->input('Customer.0.accept')

As in the Book, the fields for models with the hasMany association need a index, in that case, the 0.
