CakePHP -复缔合

Question

我刚开始接触PHP，我有一些问题

有三种模式:守护者，学生和StudentFee。

的关系看起来像：守护者hasMany学生，学生hasMany StudentFee，StudentFee belongsTo守护者，学生。

，我的问题是，的StudentFee细节不是被插入的，而是插入了学生和监护人的详细信息。

我的模特就像

class Guardian extends AppModel {
    public $name = 'Guardian';

    public $recursive =2;
    public $hasMany = array(
            'Student' => array(
                'className'     => 'Student',
                'dependent'     => true
            )
    );

}

class Student extends AppModel {
    public $name = 'Student';

        public $hasMany = array(
            'StudentFee' => array(
                'className'     => 'StudentFee',
                'dependent'     => true
            )

    );
}

class StudentFee extends AppModel {
    public $name = 'StudentFee';
    public $belongsTo = array(
                    'Guardian' => array(
                    'className'     => 'Guardian',
                    'dependent'     => true
            ),
                'Student' => array(
                    'className'     => 'Student',
                    'dependent'     => true
            )
    );
}

在我的控制器中，我使用了saveAssociated()，如下所示

$this->Guardian->set($this->request->data);
$this->Guardian->saveAssociated($this->Guardian->data, array('validate' => false)); 

请帮忙解决这个问题，谢谢。

Answer 1

对我来说正确的是：

模型

// Guardian
    $hasMany = array(
      'Student' => array('clasName' => 'Student', 'foreignKey' => 'guardian_id')
    );

// Student
    $belongsTo = array(
      'Guardian' => array('clasName' => 'Guardian', 'foreignKey' => 'guardian_id')
    );

    $hasMany = array(
      'StudentFee' => array('clasName' => 'StudentFee', 'foreignKey' => 'student_id')
    );

// StudentFee
    $belongsTo = array(
      'Student' => array('clasName' => 'Student', 'foreignKey' => 'student_id')
    );

你的数据(帖子)，也许是这样的：

[Guardian] => array(
),
['Student'] => array(
  [0] => array(
    ['StudentFee'] => array(
    )
  ),
  [1] => array(
    ['StudentFee'] => array(
    )
  )
)

所以，只需保存：

// use the deep option to save items after the second level
$this->Guardian->saveAssociated($this->request->data, array('deep' => true));

希望这能帮到你。请试一试，如果有效，请告诉我。
