從相關車型的另一種形式填寫一個表格的外鍵字段我有兩個相關的表(型號)[子與主鍵id
]和[案例與外鍵sub_id
。我使用id=4
創建了Sub。我想創建案例模型的數據在view.php(表格)子模型。我做了一個「創建案例」按鈕,它涉及Case模型的actionCreate
。在yii2
這是我在亞/ view.php「創建案例」按鈕:
<?= Html::a(Yii::t('app','Create Case'), ['/case/create', 'sub_id' => $model->id], ['class' => 'btn btn-primary']) ?>
它看起來像在 picture
這個按鈕叫我去案例模型,其中的創建形式我應該得到的場sub_id = 4。現在我_form.php這個具有
<?= $form->field($model, 'sub_id')->textInput() ?>
我應該改變什麼來取得編號自動填寫領域sub_id父模型?
更新:我從適當的視圖,控制器文件中添加了相關的代碼。 我沒有更改模型文件。
CaseController.php文件看起來像下面所示
class CaseController extends Controller
{
public function behaviors()
{
return [
'verbs' => [
'class' => VerbFilter::className(),
'actions' => [
'delete' => ['POST'],
],
],
];
}
public function actionIndex()
{
$searchModel = new CaseSearch();
$dataProvider = $searchModel->search(Yii::$app->request->queryParams);
return $this->render('index', [
'searchModel' => $searchModel,
'dataProvider' => $dataProvider,
]);
}
public function actionView($id)
{
return $this->render('view', [
'model' => $this->findModel($id),
]);
}
public function actionCreate($sub_id)
{
$model = new Case();
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('create', [
'model' => $model,
'parent' => $sub_id
]);
}
}
public function actionUpdate($id)
{
$model = $this->findModel($id);
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('update', [
'model' => $model,
]);
}
}
public function actionDelete($id)
{
$this->findModel($id)->delete();
return $this->redirect(['index']);
}
protected function findModel($id)
{
if (($model = Case::findOne($id)) !== null) {
return $model;
} else {
throw new NotFoundHttpException('The requested page does not exist.');
}
}
}
子/ view.php文件:
<?php
use yii\helpers\Html;
use yii\widgets\DetailView;
$this->title = $model->id . ": " . $model->fullname;
$this->params['breadcrumbs'][] = ['label' => Yii::t('app', 'Subs'), 'url' => ['index']];
$this->params['breadcrumbs'][] = $this->title;
?>
<div class="sub-view">
<h3><?= Html::encode($this->title) ?></h3>
<?= DetailView::widget([
'model' => $model,
'attributes' => [
'id',
'address_id',
'address.region.name',
[
'label' => 'address',
'value' => 'Street: ' . $model->address->street . ' House ' . $model->address->house . ' Flat ' . $model->address->flat
],
],
]) ?>
<p>
<?= Html::a(Yii::t('app', 'Create Case'), ['/case/create', 'sub_id'=>$model->id], ['class' => 'btn btn-success']) ?>
</p>
</div>
殼體/ _form.php這個文件:
<?php
use yii\helpers\Html;
use yii\widgets\ActiveForm;
<div class="case-form">
<?php $form = ActiveForm::begin(); ?>
<?= $form->field($model, 'id')->textInput() ?>
<?php if($model->isNewRecord && isset($parent_id)) {
$model->sub_id = $parent_id;
} ?>
<?= $form->field($model, 'sub_id')->textInput(['readonly' => true, 'value' => $model->sub_id]) ?>
<?= $form->field($model, 'case_date')->textInput() ?>
<div class="form-group">
<?= Html::submitButton($model->isNewRecord ? Yii::t('app', 'Create') : Yii::t('app', 'Update'), ['class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']) ?>
</div>
<?php ActiveForm::end(); ?>
</div>
