cakephp 模型验证错误消息未显示在 hasOne 关联中

Question

我想用association 以单一形式进行model 验证。我有两个表users（父表）和user_details（子表）。现在模型验证仅适用于用户表。我也希望它用于 userDetails 表。它们之间的关系是hasOne。

验证仅适用于用户表，因为我只为用户表创建了 newEntity。

usersController.php（控制器代码）

 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（父模型）

 public function validationDefault(Validator $validator) {
        $validator
                ->integer('id')
                ->allowEmpty('id', 'create');

        $validator
                ->email('email')
                ->requirePresence('email', 'create')
                ->notEmpty('email');


        $validator
                ->scalar('mobile')
                ->maxLength('mobile', 10,'Maximum length should be 10 digits')
                ->minLength('mobile', 10,'Minimum length should be 10 digits')
                ->requirePresence('mobile', 'create')
                ->notEmpty('mobile');

        $validator
                ->scalar('password')
                ->maxLength('password', 20,'Minimum length should be 20 digits')
                ->minLength('password', 4,'Minimum length should be 4 digits')
                ->requirePresence('password', 'create')
                ->notEmpty('password');


        return $validator;
    }

UserDetailsTable.php（子模型）

 public function validationDefault(Validator $validator)
    {
        $validator
            ->integer('id')
            ->allowEmpty('id', 'create');

        $validator
            ->scalar('name')
            ->maxLength('name', 50)
            ->requirePresence('name', 'create')
            ->notEmpty('name');

        $validator
            ->scalar('pin')
            ->maxLength('pin', 6)
            ->requirePresence('pin', 'create')
            ->notEmpty('pin');

        $validator
            ->scalar('address')
            ->maxLength('address', 4294967295)
            ->requirePresence('address', 'create')
            ->notEmpty('address');

        return $validator;
    }

添加.ctp

这是图片供参考

在此图片中，所有字段均为必填项 所有字段都来自用户表...只有地址字段来自 user_details 表。现在您可以看到显示名字字段的错误消息但未显示地址字段的错误消息。验证适用于地址字段但不知道为什么错误消息不显示。

users 表中的名字和 user_details 表中的地址

提前致谢

您正在尝试使用错误数据 ($this->request->getData()) 修补您的详细信息实体。但实际上，没有必要在 add 函数中创建、修补和保存单独的实体，因为第一级关联将为您透明地处理。这应该可以正常工作：

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'));
}

或者，至少，它应该在您更正详细信息实体中的字段名称以包含“user_detail”时，正如@ndm 所说；您上面的 HTML 仍然显示 $this->Form->control('address',...) 而不是 $this->Form->control('user_detail.address',...)，但它还包括城市和州的字段，这些字段不在您的屏幕截图中，因此不清楚您当前的版本可能是什么样子。

Answer 2

验证仅适用于用户表，因为我只为用户表创建了 newEntity。

这与它无关。问题是您没有正确遵循命名约定。

文件名必须匹配类名，所以它是UserDetailsTable.php，而不是UserDetails.php、UsersTable.php，而不是usersTable.php等。

hasOne 关联的正确属性名称是关联名称的单数、带下划线的变体，因此对于 UserDetails，这将是 user_detail，因此相关表单控件的名称应该是 @987654332 @。
