Question

StackExchange的长期被动用户，我在这里不知所措。它可能非常简单，但我被卡住了。我使用gii-enhanced来构建模型和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经存在现有的ordenes模型。
facturas模型可以链接到ordenes模型。
Ordenes有一个金额字段，facturas也是如此。

我目前所拥有的：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模型可以有多个与之相关的facturas模型。

我想要实现的是，当我将 facturas 模型链接到ordenes模型时，从 ordenes 的数量中减去facturas模型的数量model和保存到 ordenes 表的新值。因此，如果我已经有一个 ordenes 模型，其金额为200000美元，并且链接到一个金额为$ 150000的 facturas 模型，则更新的 ordenes 模型的金额应为$ 50000。

facturasController中的相关代码：

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,
            ]);
        }
    }

视图中的相关字段：

<?= $form->field($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
        ],
    ]); ?>

这只是一个建议你应该填充模型Facturas重新检索与此订单相关的事实，然后正确地分配你需要的值到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,
            ]);
        }
    }

根据您的上一条评论，这可能是您问题的更准确答案

假设订单模型是名称订单在Facturas中，您有一个名为fk_orders的字段，您可以在该字段中传递用户在视图中选择的值，并且可以链接相关的订单

然后在Facturas Controller中你可以

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,
            ]);
        }
    }
