【问题描述】：

我有一个用户模型，它与员工模型具有 hasOne 关系。当我保存一个用户时，我还在Employees 表中添加了一条带有user_id 的记录。这很好用。

Employee 可以通过 CoursesEmployees 表关联到 belongsToMany Courses。当我只保存员工时，这可以保存。

我的问题是我想保存所有 3 三个但课程没有保存。

保存用户 -> 使用新的 user_id 保存员工 -> 保存为新员工选择的课程，并在 courses_employees 中使用employee_id

EmployeesTable.php

public function initialize(array $config)
{
    $this->table('employees');
    $this->displayField('name');
    $this->primaryKey('id');
    $this->addBehavior('Timestamp');
    $this->belongsTo('Users', [
        'foreignKey' => 'user_id',

    ]);
    $this->belongsTo('Hotels', [
        'foreignKey' => 'hotel_id',
        'joinType' => 'INNER'
    ]);
    $this->belongsToMany('Courses', [
        'foreignKey' => 'employee_id',
        'targetForeignKey' => 'course_id',
        'joinTable' => 'courses_employees'
    ]);
}

用户添加.ctp:

<?= $this->Form->create($user) ?>
<fieldset>
    <legend><?= __('Add User') ?></legend>
    <?php
        echo $this->Form->input('role_id', ['options' => $roles, 'empty' => true]);
        echo $this->Form->input('email');
        echo $this->Form->input('active');
        echo $this->Form->input('activation_key');
        echo $this->Form->input('password');
        echo $this->Form->input('employee.name');
        echo $this->Form->input('employee.email');
        echo $this->Form->input('employee.surname');
        echo $this->Form->input('employee.employee_num');
        echo $this->Form->input('employee.courses._ids', ['options' => $courses]);
    ?>
</fieldset>
<?= $this->Form->button(__('Submit')) ?>
<?= $this->Form->end() ?>

这里是发送到add方法保存的post数据。这样，用户和员工就可以正确保存，但不会记录在 courses_employees 中。

如果我将员工从员工控制器中保存，则 courses_employees 可以添加，所以我知道关联设置正常。

[
'role_id' => '1',
'email' => 'asdasd@asdasd.com',
'active' => '11111111111',
'activation_key' => '1',
'password' => 'asdasdadasdasdasda',
'employee' => [
    'name' => 'asdasdasdasd',
    'email' => 'asdasdasd2dasd.com',
    'surname' => 'asdasdads',
    'employee_num' => 'asdasdadasdas',
    'courses' => [
        '_ids' => [
            (int) 0 => '2'
        ]
    ]
]
]

用户控制器.php

public function add()
{
    $this->loadModel('Courses');
    $user = $this->Users->newEntity();
    if ($this->request->is('post')) {
        $user = $this->Users->patchEntity($user, $this->request->data, [
            'associated' => ['Employees', 'Courses']
        ]);
        if ($this->Users->save($user)) {
            $this->Flash->success(__('The user has been saved.'));
            return $this->redirect(['action' => 'index']);
        } else {
            $this->Flash->error(__('The user could not be saved. Please, try again.'));
        }
    }
    $roles = $this->Users->Roles->find('list', ['limit' => 200]);
    $courses = $this->Courses->find('list', ['limit' => 200]);
    $this->set(compact('user', 'roles', 'courses'));
    $this->set('_serialize', ['user']);
}

【解决方案1】：

我找到了解决方案。我再次阅读了食谱，并在其中一个示例中注意到了 sn-ps 'associated' => ['Tags', 'Comments.Users']

我已经将它应用到我的控制器上，它现在可以工作了。它在各个层面都在节省。

$user = $this->Users->patchEntity($user, $this->request->data, [
    'associated' => ['Employees', 'Employees.Courses']
]);
