  $model=new Event('create');
  $model->attributes=$_POST['Event'];
  if($model->save()){
    $pkg = new Package(); 
    $pkg->attributes=$_POST['Package'];
    $pkg->event_id = $model->id;
    $pkg->save();
  }

Event 模型与 Event 的所有 POST 变量一起正确保存，而 Package 仅设置了 event_id，但没有设置任何属性（它们都是 NULL）。我究竟做错了什么？

注意：Event 对象是我的前任编写的，Package 对象是我新增的。

如果要通过以下方式设置属性：

$pkg->attributes=$_POST['Package'];

那么您必须为可以以这种方式设置的任何属性设置规则。

你需要这样的东西：

public function rules()
{
    // NOTE: you should only define rules for those attributes that
    // will receive user inputs.
    return array(
        array('package_name', 'required'),
        array('package_name', 'length', 'max' => 255),
        // or
        array('package_name', 'length', 'max' => 255, 'on' => 'insert'),
        // at least (when no validation is required):
        array('package_name', 'safe'),
        // ...
        // and so on.. 
    );
}

您需要以这种方式设置的任何属性的规则。

如果没有为属性设置规则，您只能通过$pkg->attribute_name = $value;

规则喜欢array('', 'safe', 'on'=>'search'),或array('', 'numerical'),什么都不做（导致属性列表为空）。

        );
      }public function relations()
      {
        // NOTE: you may need to adjust the relation name and the related

        return array(

        );
      }public function attributeLabels()

          'package_name'  => 'Package name',
          'event_banner'  => 'Event Banner',
          'ad_placement'  => 'Ad Placement in Event Program',
          'logo_on_step'  => 'Logo on Step & Repeat',
          'use_evt_pics'  => 'Usage of Event Pictures',

          'water_bottles' => 'Water Bottles'
        );
      } 
      ....
    }

如果它不起作用，那么您可以尝试，htere is validate()method before save()：

  $model=new Event('create');
  $model->attributes=$_POST['Event'];
  if($model->validate()){
    $model->save();
  }
  else{
      echo CHtml::errorSummary($model);
  }

这将说明什么是错误。

永远不要直接保存，保存前验证它。
