Getting Data for Multiple Models
|
|
================================
|
|
|
|
When dealing with some complex data, it is possible that you may need to use multiple different models to collect
|
|
the user input. For example, assuming the user login information is stored in the `user` table while the user profile
|
|
information is stored in the `profile` table, you may want to collect the input data about a user through a `User` model
|
|
and a `Profile` model. With the Yii model and form support, you can solve this problem in a way that is not much
|
|
different from handling a single model.
|
|
|
|
In the following, we will show how you can create a form that would allow you to collect data for both `User` and `Profile`
|
|
models.
|
|
|
|
First, the controller action for collecting the user and profile data can be written as follows,
|
|
|
|
```php
|
|
namespace app\controllers;
|
|
|
|
use Yii;
|
|
use yii\base\Model;
|
|
use yii\web\Controller;
|
|
use yii\web\NotFoundHttpException;
|
|
use app\models\User;
|
|
use app\models\Profile;
|
|
|
|
class UserController extends Controller
|
|
{
|
|
public function actionUpdate($id)
|
|
{
|
|
$user = User::findOne($id);
|
|
if (!$user) {
|
|
throw new NotFoundHttpException("The user was not found.");
|
|
}
|
|
|
|
$profile = Profile::findOne($user->profile_id);
|
|
|
|
if (!$profile) {
|
|
throw new NotFoundHttpException("The user has no profile.");
|
|
}
|
|
|
|
$user->scenario = 'update';
|
|
$profile->scenario = 'update';
|
|
|
|
if ($user->load(Yii::$app->request->post()) && $profile->load(Yii::$app->request->post())) {
|
|
$isValid = $user->validate();
|
|
$isValid = $profile->validate() && $isValid;
|
|
if ($isValid) {
|
|
$user->save(false);
|
|
$profile->save(false);
|
|
return $this->redirect(['user/view', 'id' => $id]);
|
|
}
|
|
}
|
|
|
|
return $this->render('update', [
|
|
'user' => $user,
|
|
'profile' => $profile,
|
|
]);
|
|
}
|
|
}
|
|
```
|
|
|
|
In the `update` action, we first load the `$user` and `$profile` models to be updated from the database. We then call
|
|
[[yii\base\Model::load()]] to populate these two models with the user input. If successful we will validate
|
|
the two models and save them. Otherwise we will render the `update` view which has the following content:
|
|
|
|
```php
|
|
<?php
|
|
use yii\helpers\Html;
|
|
use yii\widgets\ActiveForm;
|
|
|
|
$form = ActiveForm::begin([
|
|
'id' => 'user-update-form',
|
|
'options' => ['class' => 'form-horizontal'],
|
|
]) ?>
|
|
<?= $form->field($user, 'username') ?>
|
|
|
|
...other input fields...
|
|
|
|
<?= $form->field($profile, 'website') ?>
|
|
|
|
<?= Html::submitButton('Update', ['class' => 'btn btn-primary']) ?>
|
|
<?php ActiveForm::end() ?>
|
|
```
|
|
|
|
As you can see, in the `update` view you would render input fields using two models `$user` and `$profile`.
