CakePHP 4.1 保存 belongsTo 关联不起作用

Question

我有两个数据库 tables - Users 和 UserTypes，其中 Users 有一个外键 user_type_id。以下是他们的样板模型代码。

Entity/User.php:

class User extends Entity {
    protected $_accessible = [
        'id' => true,
        'email' => true,
        'password' => true,
        'name' => true,
        'user_type_id' => true, // added this as an experiment now, but I shouldn't need it if I understand correctly
        'user_type' => true
    ];
}

Entity/UserType.php:

class UserType extends Entity {
    protected $_accessible = [
        'id' => true,
        'name' => true,
        'users' => true,
    ];
}

Table/UsersTable.php:

class UsersTable extends Table
{
public function initialize(array $config): void
{
    parent::initialize($config);

    $this->setTable('users');
    $this->setDisplayField('name');
    $this->setPrimaryKey('id');

    $this->belongsTo('UserTypes', [
        'joinType' => 'INNER'
    ]);
}


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

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

    $validator
        ->scalar('password')
        ->maxLength('password', 255)
        ->requirePresence('password', 'create')
        ->notEmptyString('password');

    $validator
        ->scalar('name')
        ->maxLength('name', 255)
        ->allowEmptyString('name');

    return $validator;
}

public function buildRules(RulesChecker $rules): RulesChecker
{
    $rules->add($rules->isUnique(['email']));
    $rules->add($rules->existsIn(['user_type_id'], 'UserTypes'));

    return $rules;
}
}

Table/UserTypesTable.php:

class UserTypesTable extends Table
{
    public function initialize(array $config): void
    {
        parent::initialize($config);

        $this->setTable('user_types');
        $this->setDisplayField('name');
        $this->setPrimaryKey('id');
        $this->hasMany('Users');
    }

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

        $validator
            ->scalar('name')
            ->requirePresence('name', 'create')
            ->notEmptyString('name');

        return $validator;
    }
}

现在的问题是，我似乎无法将记录的user_type_id 字段保存到数据库的users table 中。为了重现该问题，我在 UsersController.php 中创建了以下简单操作：

public function testAdd()
{
    $testUser = $this->Users->newEmptyEntity();
    $testUser->name = "Test";
    $testUser->email = "test@test.com";
    $testUser->password = "secret";
    $testUser->user_type = $this->Users->UserTypes->get(1); // this exists and I've verified get() finds it correctly
    $this->Users->save($testUser);
}

结果是 SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails，尝试的查询是 INSERT INTO users (email, password, name) VALUES (:c0, :c1, :c2)，显然没有必要的 user_type_id 字段。

我已经尝试更改现有用户的用户类型，但没有失败（因为已经满足 FK 约束），但也没有发生任何更改。

我也试过 $this->Users->save($testUser, ['associated' => ['UserTypes']]);，结果 INSERT SQL 查询没有任何改变。

所以我的问题是，如何插入和更新我的用户实体的外键字段？

---- 编辑 ----

运行 debug(get_class($this->Users)) 就在 save() 之前：

APP/Controller/UsersController.php (line 270)
'App\Model\Table\UsersTable'

并且运行 debug($testUser) 在 save() 之前产生：

APP/Controller/UsersController.php (line 271)
object(App\Model\Entity\User) id:0 {
'name' => 'Test'
'email' => 'test@test.com'

写下@ndm 的评论作为答案，以帮助最终遇到同样问题的任何人。原来我的 ORM 模式在我添加 user_types 数据库 table 之前被缓存了。清除 /tmp/cache/models 对我有用。当心缓存！
