cakePHP saveAssociated belongsTo

Question

saveAssociated与belongsTo模型一起使用吗？我有 Donor 模型，该模型属于 User 模型。这意味着user_id存储在Donor模型中。我正在尝试使用saveAssociated()在一次通话中保存捐赠者/用户数据。然而，这似乎不起作用

她是我尝试过的：

 $this->request->data['User'][0]['role'] = 'donor'; //tried without the `[0]`
 $this->request->data['User'][0]['activation_secret'] =  $activation_secret;
 if($this->Donor->saveAssociated($this->request->data, array('deep' => true))){
     //success message 
 }

我这样做是为了解决这个问题：

$user = $this->Donor->User->save($this->request->data);
if(!empty($user)){
    $this->request->data['Donor']['user_id'] = $this->Donor->User->getLastInsertId();
}
if($this->Donor->save($this->request->data)){
// success message
}

这是正确的方法吗？或者我错过了什么？

[编辑]

我的表单遵循此模式

<?php
            echo $this->Form->create('Donor');
            echo $this->Form->input('name', array('id' => 'name','div' => 'inline-input'));
            echo $this->Form->input('surname', array('id' => 'surname','div' => 'inline-input'));
 ?>

NB。要保存的关联模型数据是硬编码的，如上面的保存操作中所示。

尝试以下方法：

$this->request->data['User']['role'] = 'donor';
$this->request->data['User']['activation_secret'] =  $activation_secret;

unset($this->Donor->validate['user_id']); // This might solve your problem

if($this->Donor->saveAssociated($this->request->data, array('deep' => true))){
    //success message 
}
