Yii2 - 從更新表單更新另一個模型的單個字段

Question

StackExchange的長期被動用戶，我在此處不知所措。這可能超級簡單，但我卡住了。我已經使用gii-enhanced來建立模型和CRUD。

• 我有兩個模型：ordenes和facturas。

• 當我更新facturas模型時，我可以將它鏈接到已有的 現有ordenes模型。

• facturas模型可以鏈接到ordenes模型。

• Ordenes有數量字段，因此facturas。

我現在有什麼：我可以將facturas模型鏈接到已經存在的ordenes模型。一個facturas模型只能有一個ordenes模型，而ordenes模型可以有多個facturas模型鏈接到它。

我想達成的目標是，當我從facturas模型鏈接facturas模型到模型ordenes量從ordenes模型並保存到新價值的金額中扣除ordenes表。因此，如果我已經有一個金額爲200000美元的ordenes模型，並且鏈接到該模型的金額爲150000美元，則更新的或模型應該具有金額50000美元。

相關的代碼在facturasController：

public function actionUpdate($id) 
    { 
     $model = $this->findModel($id); 

     if ($model->loadAll(Yii::$app->request->post()) && $model->saveAll()) { 
      return $this->redirect(['view', 'id' => $model->idfacturas]); 
     } else { 
      return $this->render('update', [ 
       'model' => $model, 
      ]); 
     } 
    }

Answer 1

這僅僅是一個建議
你應該填充模型Facturas retriving與此相關的訂單facturas然後分配適當的，你需要根據你最後的評論這可以在facturas模型

use common\models\Facturas; 

public function actionUpdate($id) 
    { 
     $model = $this->findModel($id); 


     if ($model->loadAll(Yii::$app->request->post()){ 
      $modelFacturas = Facturas::find() 
      ->(['your_id_fatcuras' => $model->your_id_facturas ])->one(); 
      $modelFacturas->you_field_to_change = $model->value1 - $modelFacturas->value2; 
      $model->save(); 
      $modelFacturas->save(); 

      return $this->redirect(['view', 'id' => $model->idfacturas]); 
     } else { 
      return $this->render('update', [ 
       'model' => $model, 
      ]); 
     } 
    } 

值更準確地回答您的問題

假設您的訂單模型是名稱訂單 並且在Facturas中您有一個名爲fk_orders的字段，您可以在視圖中傳遞用戶選擇的值，並且可以將相關特德在Facturas控制器訂購

然後你就可以

use common\models\Orders; 

public function actionUpdate($id) 
    { 
     $model = $this->findModel($id); // retrive the Factursa model 


     if ($model->loadAll(Yii::$app->request->post()){ 
      $modelOrders = Orders::find() 
      ->(['id_orders' => $model->fk_orders ])->one(); 
      $modelOrders->amount = $modelOrders->amount - $model->value_to_subtract; 
      $model->save(); 
      $modelOrders->save(); 

      return $this->redirect(['view', 'id' => $model->idfacturas]); 
     } else { 
      return $this->render('update', [ 
       'model' => $model, 
      ]); 
     } 
    }
