yii没有保存模型

Question

$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(); 
    } 

事件模型被正确保存与事件的所有POST变量，而包只有event_id设置，但没有设置属性（它们都是NULL）。我究竟做错了什么？

注意：Event对象已经由我的前任编写，Package对象是我做的一个新增加。

Answer 1

如果你想通过设置属性：

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

那么你必须设置规则，可以这样设置任何属性。

你需要的东西是这样的：

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.. 
    ); 
} 

你需要规则，你要这样设置的任何属性。

如果没有规则属性设置，你就可以将其值设置只能通过$pkg->attribute_name = $value;

规则像array('', 'safe', 'on'=>'search'),或array('', 'numerical'),什么也不做（事业属性列表为空）。

 class Package extends CActiveRecord 
     { 
     public static function model($className=__CLASS__) 
     { 
     return parent::model($className); 
     } 
    public function tableName() 
     { 
     return 'tbl_package'; 
     } 
    public function rules() 
     { 
     // NOTE: you should only define rules for those attributes that 
     // will receive user inputs. 
     return array(
      // The following rule is used by search(). 
      // Please remove those attributes that should not be searched. 
      array('ad_placement, logo_on_step, ...', 'safe', 'on'=>'search'), //note put here all attrs name that you feel those attrs needs to be assigned from POST like: `$pkg->attributes=$_POST['Package'];` 
array('event_id', 'numerical'), 

     ); 
     }public function relations() 
     { 
     // NOTE: you may need to adjust the relation name and the related 
     // class name for the relations automatically generated below. 
     return array(
      'event' => array(self::BELONGS_TO, 'Event', 'id') 
     ); 
     }public function attributeLabels() 
     { 
     return array(
      'event_id'  => 'Event ID', 
      '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', 
      'exhibition' => 'Exhibition Booth/Space', 
      'inc_press'  => 'Inclusion in Press', 
      'print_ads'  => 'Insertion in Print Ads', 
      'online_ads' => 'Insertion in Online Ads', 
      'attendee_bags' => 'Attendee Bags', 
      'charging_st' => 'Charging Stations', 
      'cups'   => 'Coffee/Water Cups', 
      'distr_items' => 'Distributable Items', 
      'lanyards'  => 'Lanyards', 
      'napkins'  => 'Napkins', 
      'notebooks'  => 'Notebooks', 
      'pens'   => 'Pens', 
      'seat_covers' => 'Seat Covers', 
      'snack_pack' => 'Snack Packaging', 
      'water_bottles' => 'Water Bottles' 
     ); 
     } 
     .... 
    } 

如果它不工作，那么你可以尝试，htere是validate()方法之前save()：

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

这会分不清什么是错误。

切勿直接保存，在保存前进行验证。
