Yii2 - 完整性約束違規 - yii \ db \ IntegrityException

Question

我試圖將數據添加到我的數據庫時遇到了一個相當困難的錯誤。它不斷告訴我，有一個誠信違規行爲，即

SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`ticketing_system`.`parcels`, CONSTRAINT `FK_parcels_customers_customer_id` FOREIGN KEY (`sender_id`) REFERENCES `customers` (`customer_id`)) 
The SQL being executed was: INSERT INTO `parcels` (`parcel_id`) VALUES (DEFAULT) 

我已經檢查被插入的價值和所有的人都在引用表採摘。有趣的是，當我回顯值並使用它們直接通過PHPMyAdmin上的SQL查詢更新數據庫時，數據庫填充良好，沒有任何問題。同樣，當我嘗試更改執行的SQL查詢中出現的外鍵順序時，第一個失敗，這意味着模型的所有外鍵都失敗。

EDITED

這是我在ParcelsController

public function actionCreate() 
{ 
    $model = new Parcels(); 
    $customerModel = new Customers(); 

    //checking whether we are getting the logged in user id value 
    Yii::info("User id=".Yii::$app->user->id); 

    $model->received_by_id = Yii::$app->user->id; 

    if (Yii::$app->request->post()) { 

     $data = Yii::$app->request->post('Customers'); 

     $sender_id = Customers::create([ 
      'name' => $data['name'], 
      'mobile_number' => $data['mobile_number'], 
      'sex' => $data['sex'], 
      'address' => $data['address'], 
      'registered_by_id' => $model->received_by_id, 
     ]); 

     $data = Yii::$app->request->post('Parcels'); 

     $receiver_id = Customers::create([ 
      'name' => $data['name'], 
      'mobile_number' => $data['mobile_number'], 
      'sex' => $data['sex'], 
      'address' => $data['address'], 
      'registered_by_id' => $model->received_by_id, 
     ]); 

     $model->consignment_number = $model->generateUniqueRandomString("consignment_number"); 
     $model->source_id = $model->receivedBy->station_id; 

     $model->parcel_id = Parcels::create([ 
      'consignment_number' => $model->consignment_number, 
      'sender_id' => $sender_id, 
      'receiver_id' => $receiver_id, 
      'source_id' => $model->source_id, 
      'destination_id' => $data['destination_id'], 
      'type_id' => $data['type_id'], 
      'weight' => $data['weight'], 
      'cost' => $data['cost'], 
      'parcel_info' => $data['parcel_info'], 
      'received_by_id' => $model->received_by_id, 
     ]); 

     // return $this->redirect(['view', 'id' => $model->parcel_id]); 
    } else { 
     return $this->render('create', [ 
      'model' => $model, 'customerModel' => $customerModel, 
     ]); 
    } 
}

這裏是在地塊型號

public function generateUniqueRandomString($attribute, $length = 10) { 

    $randomString = Yii::$app->getSecurity()->generateRandomString($length); 

    $randomString = strtoupper($randomString); 

    if(!$this->findOne([$attribute => $randomString])) 
     return $randomString; 
    else 
     return $this->generateUniqueRandomString($attribute, $length); 

} 

Answer 1

對不起功能generateUniqueRandomString（）打擾你們。我能夠知道我出錯的地方。在包裹模型的建立（）函數，我只是創造了新的變量，未能將它們綁定到模型，即

$consignment_number = $data['consignment_number']; 
$receiver_id = $data['receiver_id']; 
$sender_id = $data['sender_id']; 
$source_id = $data['source_id']; 
$destination_id = $data['destination_id']; 
$type_id = $data['type_id']; 
$weight = $data['weight']; 
$cost = $data['cost']; 
$parcel_info = $data['parcel_info']; 
$received_by_id = $data['received_by_id']; 

本來應該是：

$model->consignment_number = $data['consignment_number']; 
$model->weight = $data['weight']; 
$model->cost = $data['cost']; 
$model->parcel_info = $data['parcel_info']; 
$model->received_by_id = $data['received_by_id']; 
$model->status = $data['status']; 
$model->receiver_id = $data['receiver_id']; 
$model->sender_id = $data['sender_id']; 
$model->source_id = $data['source_id']; 
$model->destination_id = $data['destination_id']; 
$model->type_id = $data['type_id']; 

對不起，把你的時間，因爲我的粗心大意。
