Symfony：保存表单对象的问题

Question

我在一个项目中使用带有 Propel ORM 的 SF 1.4.8。我有一个允许用户保存其用户配置文件的操作。它看起来像这样：

public function executeEditUser(sfwebRequest $request)
{
    // some code commented out for brevity
    $tainted_values = $user_profile->toArray(BasePeer::TYPE_FIELDNAME);   

    $this->form->bind(array_merge($tainted_values, $form_params), $file_params);

    if ($this->form->isValid())
    {
        $this->form->save();
        return $this->redirect('@user_account');
    }    
}

User 表单类覆盖 doSave() 和 Update() 方法，如下所示：

protected function doSave($con = null)
{
    $profile = $this->getObject();
    // code commented out (saving files etc)

     return parent::doSave($con);
}

public function updateObject($values = null)
{
    $object = parent::updateObject($values);
    $paththname = $object->getPictPath();

    if (!empty($pathname))
    {
        $image_name = basename($pathname);
        $object->setPictPath($image_name);
    }
    return $object;
}

当用户编辑并保存配置文件时 - 代码正常运行，但对象不会在数据库中更新。我单步执行了代码，在表单的 save() 方法中，对象执行路径表明没有对对象进行任何更改（即使用户输入的值已正确绑定并且 validate() 方法返回 true。

这是 Apache 错误日志文件中打印的警告堆栈跟踪：

Answer 1

答案与此问题相同：Symfony form values missing

即重写的 postValidate() 方法不返回 $values 是罪魁祸首！
