Yii2 - 从更新表单更新另一个模型的单个字段

Question

StackExchange的长期被动用户，我在此处不知所措。这可能超级简单，但我卡住了。我已经使用gii-enhanced来建立模型和CRUD。

• 我有两个模型：ordenes和facturas。

• 当我更新facturas模型时，我可以将它链接到已有的 现有ordenes模型。

• facturas模型可以链接到ordenes模型。

• Ordenes有数量字段，因此facturas。

我现在有什么：我可以将facturas模型链接到已经存在的ordenes模型。一个facturas模型只能有一个ordenes模型，而ordenes模型可以有多个facturas模型链接到它。

我想达成的目标是，当我从facturas模型链接facturas模型到模型ordenes量从ordenes模型并保存到新价值的金额中扣除ordenes表。因此，如果我已经有一个金额为200000美元的ordenes模型，并且链接到该模型的金额为150000美元，则更新的或模型应该具有金额50000美元。

相关的代码在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, 
      ]); 
     } 
    } 

视图中的相关领域：

<?= $form->field($model, 'ordenes_idordenes')->widget(\kartik\widgets\Select2::classname(), [ 
     'data' => \yii\helpers\ArrayHelper::map(\frontend\models\Ordenes::find()->orderBy('idordenes')->asArray()->all(), 'idordenes', 'numero'), 
     'options' => ['placeholder' => Yii::t('app', 'Vincular Orden de Compra')], 
     'pluginOptions' => [ 
      'allowClear' => true 
     ], 
    ]); ?>

Answer 1

这仅仅是一个建议
你应该填充模型Facturas retriving与此相关的订单facturas然后分配适当的，你需要根据你最后的评论这可以在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, 
      ]); 
     } 
    } 

值更准确地回答您的问题

假设您的订单模型是名称订单 并且在Facturas中您有一个名为fk_orders的字段，您可以在视图中传递用户选择的值，并且可以将相关特德在Facturas控制器订购

然后你就可以

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, 
      ]); 
     } 
    }
