Question

我在帐户和用户表之间有一对一的关系，我正在尝试在帐户模型的beforeSave中进行所有预处理，但似乎我只能这样做更改$this->data['Account'][...]而不是$this->data['User'][...]的值，为什么会这样？

function beforeSave() {
  // Check if this is a create or update action
  if (empty($this->data['Account']['uid'])) {
    $this->data['Account']['uid'] = uniqid();
    $this->data['Account']['date_registration'] = date('Y-m-d');
    $this->data['Account']['state'] = 1;

    // this won't work
    $this->data['User']['password'] = Security::hash($this->data['User']['password'], null, true);
  }
  return true;
}

另一个问题是检查用户是否在beforeSave事件中更新或创建模型的最佳方法是什么，检查empty($this->data['Account']['id']))？

感谢。

事实证明，它在CakePHP 1.3中是不可能的： http://cakephp.lighthouseapp.com/projects/42648/tickets/671-cant-modify-related-models-data-in-beforesave-when-using-saveall

我将代码移动到用户控制器，但这次问题是我无法直接访问$ this-＆gt;帐户 - ＆gt;名称，虽然我可以访问$ this-＆gt; Account-＆gt; id，这是为什么？我不得不做下面的工作场所：

function beforeSave() {

    if (empty($this->date['User']['id'])){
        $this->data['User']['password'] = Security::hash($this->data['User']['password'], null, true);

        // Username is inherited from the account name
        // TODO: the field needs to be removed, depending whether the Auth component will play nicely
        $account_name = $this->Account->read('name',$this->Account->id);
        $this->data['User']['username'] = $account_name['Account']['name'];
    }
    return true;
}

为什么我不能在CakePHP中更改另一个模型的数据
