。如何分配我的_id作爲主鍵

Question

我是新手，所以我希望你能幫助我。 我有yii2，我需要實現elasticSearch（ES）。 全部設置。 我做了標準模型和標準CRUD。就在幾個改變以實現ES樣

use yii\elasticsearch\ActiveRecord; 

但我有我的看法/ index.php文件 得到_id問題得到_id在view.php我做

$model->_id = $model->primaryKey; 

但如何我可以用index.php中的DataProvider修復它？

我的屬性

public function attributes() 
{ 
    return [ 
     '_id', 
     'first_name', 
     'last_name', 
     'email', 
     'created', 
     'brand', 
     'product', 
     'qty', 
     'sum' 
    ]; 
} 

我的規則

public function rules() 
{ 
    return [ 
     [['first_name', 'last_name', 'email', 'created', 
      'brand', 'product', 'qty', 'sum' 
     ], 
      'safe'], 
     [['qty'], 'integer'], 
     [['sum'], 'double'], 
     ['email', 'email'], 
    ]; 
} 

，我認爲它應該工作像MongoDB的，但事實並非如此。

，如果我想刪除或查看或更新數據正對的index.php我只能等環節W/O ID

附： 這裏是一個的var_dump

array (size=5) 
    0 => 
    object(frontend\models\Elastic)[67] 
     private '_id' (yii\elasticsearch\ActiveRecord) => string 'AVreA6SUvBgWLKxTzUZn' (length=20)

可以set.good運氣

$dataProvider = new ActiveDataProvider([ 
     'query' => $query, 
     'key' => ['your primaryKey'] 
     'sort' => [ 
      'defaultOrder' => ['datetime'=>SORT_DESC] 
    ], 
]);
