CakePHP 3：保存关联模型失败 [英] CakePHP 3: Save Associated Model Fail

问题描述

我在使用Cakephp 3 patchEntity保存关联模型时遇到困难。此处汇总了所涉及的模型

I'm having difficulty using Cakephp 3 patchEntity to save associated models. The models involved are summarized here

我的UsersTempTable

My UsersTempTable

 public function initialize(array $config)
{
    $this->table('users_temp');
    $this->displayField('name');
    $this->primaryKey('id');
    $this->addBehavior('Timestamp');
    $this->hasOne( 'UsersExtraTemp', [
        'foreignKey' => 'user_id'
    ]);

}

然后我的UsersExtraTempTable

Then my UsersExtraTempTable

public function initialize(array $config)
    {
        $this->table('users_extra_temp');
        $this->displayField('id');
        $this->primaryKey('id');
        $this->belongsTo('UsersTemp', [
            'foreignKey' => 'user_id',
            'joinType' => 'INNER'
        ]);
    }
    public function buildRules(RulesChecker $rules)
    {
        $rules->add($rules->existsIn(['user_id'], 'UsersTemp'));
        return $rules;
    }

保存数据的Mi函数：

Mi function to save the data:

   $user = $this->newEntity();
   $user = $this->patchEntity($user, $this->request->data, [
              'associated' => ['UsersTemp.UsersExtraTemp']
           ]);
   $this->save( $user, ['associated' => ['UsersExtraTemp']] );

我的数据数组由$ this-> debug（）

And my array of data print by $this->debug()

(
    [name] => name
    [lastname] => lastname
    [email] => [e-mail]
    [password] => password
    [passwordConfirm] => repeatPassord
    [UsersExtraTemp] => Array
        (
            [google_token] => sjskdasdadk2
        )

)

我得到一个在数据库中为user_temp创建的行，但对于我期望的一个users_extra没有任何作用。知道我在做什么错吗？

I get a row created for user_temp in the database but nothing for the one users_extra that I'm expecting. Any idea what I'm doing wrong please?

推荐答案

给出 $ this 引用 UsersTempTable ， patchEntity（） associated 选项c>不应包含该名称，因为这表明 UsersTempTable 与 UsersTempTable 相关联，情况并非如此

Given that $this refers to UsersTempTable, the associated option for patchEntity() should not contain that name, as this would suggest that UsersTempTable is associated with UsersTempTable, which is not the case.

该选项应与 save（）调用中的选项完全相同，即

The option should look exactly the same as in the save() call, ie

$user = $this->patchEntity($user, $this->request->data, [
    'associated' => ['UsersExtraTemp']
]);

此外，在数据中，您还应该为关联使用正确的属性名称，如果出现 hasOne 关联，是关联名称的单数形式，即强调的变体，即 users_extra_temp

Also in the data you should use the proper property name for the association, which, in case of a hasOne association, is the singular, underscored variant of the association name, ie users_extra_temp

(
    // ...

    [users_extra_temp] => Array
        (
            [google_token] => sjskdasdadk2
        )

)

最后但并非最不重要的一点，请确保在 UsersTemp 实体 $ _ accessible 属性

And last but not least, make sure that the property name is defined in the UsersTemp entities $_accessible property

class UsersTemp extends Entity
{
    // ...

    protected $_accessible = [
        // ...
        'users_extra_temp' => true,
        // ...
    ];

    // ...
}
