我有一个扩展 CActiveRecord 的模型，其具有以下内容 rules()方法:
/**
* @return array validation rules for model attributes.
*/
public function rules()
{
return array(
array('name, locationId', 'required'),
array('locationId', 'numerical', 'integerOnly'=>true),
array('name', 'length', 'max'=>1024),
array('name', 'safe'),
// The following rule is used by search().
// Please remove those attributes that should not be searched.
array('id, name, description, locationId', 'safe', 'on'=>'search'),
);
}
这是 actionCreate()相应 Controller 中的方法:
public function actionCreate()
{
$model = new Destination;
if ( isset($_POST['Destination']) )
{
$model->attributes = $_POST['Destination'];
// logging statement!
Yii::log("Name: {$model->name}\nLocationID: {$model->locationId}\nAll attribs:\n".CVarDumper::dumpAsString($model->attributes), 'warning', 'application.controllers.DestinationController.actionCreate');
if ( $model->save() )
$this->redirect(array('view', 'id'=>$model->id));
}
$this->render( 'create', array (
'model' => $model,
));
}
不幸的是，每次我尝试使用此操作创建新记录时，都会收到错误 name和locationId不能为空，即使它们已在表单中设置。 actionCreate() 中的日志记录语句的输出，上面看起来像这样:
2012/08/14 18:04:51 [warning] [application.controllers.DestinationController.actionCreate] Name:
LocationID:
All attribs:
array
(
'name' => 'Test Name'
'description' => 'Test Description'
'locationId' => '93'
'contactId' => ''
'accessId' => ''
'fullDistance' => ''
)
如您所见，倾销 $model->attributes显示正确的数据，但尝试获取单个属性(例如调用 $model->name 或 $model->locationId )不会返回任何内容。我通过save()追踪到了这一点, validate()等调用，看起来这导致了 required name 的规则和locationId失败。
有什么想法吗？

最佳答案
这是一次命名冲突。该数据库中有一个“属性”表，以及引用该表的关系 $model->attributes。 Yii 生成的代码在这一行进行大量赋值:
$model->attributes = $_POST['Destination'];
由于 $model->attributes 已被重新定义为关系，因此大量赋值无法正确执行。
关于validation - Yii "required"验证失败 : $model->attributes returns correct data, 但 $model->requiredAttribute 为空？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/11962930/
