CakePHP - hasMany模型的findAll（）排序

Question

以下是我的模特：

class Subject extends AppModel {
    public $belongsTo = array('SubjectGroup');
}

class SubjectGroup extends AppModel {
    public $hasMany = array('Subjects');
}

我正在检索控制器中的所有SubjectGroup，如下所示：

$this->SubjectGroup->find('all', array('order' => 'SubjectGroup.name'));

但是我如何告诉它按Subject.name命令每个SubjectGroup中的主题？

Answer 1

解决方案：

class SubjectGroup extends AppModel {

    public $hasMany = array(
        'Subject' => array('order' => 'Subject.name')
    );

}

感谢chetan patel提醒我高级选项。

Answer 2

$this->SubjectGroup->find('all', array('order' => array('SubjectGroup.name'=>'asc','Subject.name'=>'asc')));

或

class SubjectGroup extends AppModel {
public $hasMany = array(
   'Subject'=>array(
   'className' => 'Subject',
  'order' => 'Subject.name DESC', // order by descending time of Subjects
  'foreignKey' => 'subject_id')
    );
 }
