我有一个Usergroups表，什么是belongsToMany用户。
在我的控制器中
$usergroup = $this->Usergroups->get($id, ['contain' => ['Users']]);
$usergroup->users[0]->_joinData->joined = true;
if ($this->Usergroups->save($usergroup)) {
$this->Flash->success('You have successfully joined');
}
我获得了成功的Flash消息，但我的users_usergroups表中没有为用户设置joined字段。
有什么猜测？
我在保存的实体看起来像这样。
object(App\Model\Entity\Usergroup) {
'id' => (int) 22,
'name' => 'Test',
'admin_user_id' => (int) 2,
'users' => [
(int) 0 => object(App\Model\Entity\User) {
'id' => (int) 2,
'name' => 'rrd',
'active' => true,
'_joinData' => object(App\Model\Entity\UsersUsergroup) {
'id' => (int) 14,
'user_id' => (int) 2,
'usergroup_id' => (int) 22,
