yii2 ActiveData提供商

这是我的用户模型yii2 ActiveData提供商

class User extends \yii\db\ActiveRecord 
{ 

public static function tableName() 
{ 
    return 'user'; 
} 

/**

public function rules() 
{ 
    return [ 
     [[ 'created_at', 'updated_at', 'branch_id', 'postcode', 'tel_no', 'child_no','company_id'], 'integer'],

    ]; 
} 

/**

public function attributeLabels() 
{ 
    return [ 
     'id' => Yii::t('user', 'ID'), 
     'staff_id' => Yii::t('user', 'Staff ID'), 
     'username' => Yii::t('user', 'Username'), 
     'fullname' => Yii::t('user', 'Fullname'), 
     'password' => Yii::t('user', 'Password'),

    ]; 
} 

public static function find() 
{ 
    return new UserQuery(get_called_class()); 
} 

public function getCountries() 
{ 
    return $this->hasOne(Countries::classname(),['id'=>'country']); 
} 

public function getStates() 
{ 
    return $this->hasOne(States::classname(),['id'=>'state']); 
} 

public function getNext_of_kin() 
{ 
    return $this->hasMany(NextOfKin::classname(),['staff_id'=>'staff_id']); 
} 

}

这是我的看法控制器

public function actionView($staff_id) 
{ 
     $request = Yii::$app->request; 
     $model = $this->findModel($staff_id); 
     $model2 = $model ->next_of_kin; 
     //$sql = "SELECT next_of_kin.name AS Name FROM user left join next_of_kin ON next_of_kin.staff_id = user.staff_id"; 

     $dataProvider = new ActiveDataProvider([ 
     'query' => User::find() ->joinWith(['next_of_kin'])-> where(['next_of_kin.staff_id' => $staff_id]), 
    ]); 

    if($request->isAjax) 
     { 
      Yii::$app->response->format = Response::FORMAT_JSON; 

      return [ 
        'title'=> "User #".$staff_id, 
        'content'=>$this->renderAjax('view', [ 
         'model' => $model, 
         'dataProvider' => $dataProvider, 
        ]), 
        'footer'=> Html::button('Close',['class'=>'btn btn-default pull-left','data-dismiss'=>"modal"]). 
          Html::a('Edit',['update','staff_id'=>$staff_id],['class'=>'btn btn-primary','role'=>'modal-remote']) 
       ];  
     } 
     else 
     { 
      return $this->render('view', [ 
       'model' => $model, 
       'dataProvider' => $dataProvider, 
       "size" => "modal-lg", 
      ]); 
     } 
}

这是

[ 
       'label' => 'Next of Kin Details', 
       'content' => GridView::widget([ 
         'dataProvider' => $dataProvider, 
         'columns' => [ 
          ['class' => 'yii\grid\SerialColumn'], 
          'username', 
          'fullname', 
          'staff_id', 
          'next_of_kin.name', 
        ], 
       ]), 
      ],

我想从表名视图文件next_of_kin基于用户表中的员工ID。但是，保持节目的时候我尝试查看它没有设置

next_of_kin是表名？或者是用户模型中声明的关系函数的名称？ – scaisEdge

@scaisEdge两者的它。我把相同的名称 – Ron

更新你的问题，并添加relatioal功能。对于用户模型，请next_of_kin ..并在您使用$数据提供程序 – scaisEdge

为什么要使用数组，当你想用一个表/关系加入，我的意思是它不应该是错的，但它的混乱。您的查询似乎并没有错，找调试器的数据库模块，看看有什么实际的查询Yii的AR组成，并在数据库中的原始形式运行它。查询本身不破，至少从我可以告诉，DB架构，事实上，你可以查询有没有回报，你通过$ staff_id和其他一些东西，有可能被打破的方式staff_id。

activeDataProvider返回模型的集合

你可以从数据提供程序

检索模型的阵列

$myModels = $dataProvider->getModels();

例如：获得的第一个元素（用户模式）next_of_kin模型

$my_next_of_kin = $myModels[0]->next_of_kin;

迭代通过模型获得价值;

foreach ($my_next_of_kin as $key => $value) { 
    echo $value->your_next_of_kin_col; 
    }

它只能与一个一对一的关系！你有一对多的。

public function getNext_of_kin() 
{ 
    return $this->hasMany(NextOfKin::classname(),['staff_id'=>'staff_id']); 
} 

'columns' => [ 
     ['class' => 'yii\grid\SerialColumn'], 
     'username', 
     'fullname', 
     'staff_id', 
     'next_of_kin.name', // "next_of_kin" should be one-to-one relation 
],
