同一个 ActiveForm yii2 上的多个模型

Question

同一张表格有多个模型我不想在两种模型上保存数据，但我只想在视图文件中显示一个变量

我有 2 table Organiser 和 Event Organiser 将登录并 Create Event 现在很少有字段在 table 中是通用的因此，当登录用户单击 Create Event 按钮时，我想在表单

上显示来自 Organiser table 的 address

这就是我到目前为止所做的这可能不是正确的方法所以让我知道这是否可以通过任何其他更简单的方式实现

public function actionCreate()
{
    $model = new Event();

    $model2 = $this->findModel2(Yii::$app->user->id);


    if ($model->load(Yii::$app->request->post())) {

        if($_POST['User']['address'] == null)
        {
            $model->location = $model2->address;
        }
        else{
            $model->location = $_POST['User']['address'];
        }

        $model->is_active = 1 ;

        $model->save();


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

        return $this->render('create', [
            'model' => $model,
            'model2' => $model2
        ]);
    }
}
protected function findModel2($id)
{
    if (($model2 = User::findOne($id)) !== null) {
        return $model2;
    } else {
        throw new NotFoundHttpException('The requested page does not     exist.');
    }
}

这是我的 _form.php 代码

 <?php $form = ActiveForm::begin([
    'options' => [
        'id' => 'create-event-form'
    ]
]); ?>


 <?= $form->field($model, 'interest_id')->dropDownList(
    ArrayHelper::map(Areaintrest::find()->all(),'id','area_intrest'),
    ['prompt'=> 'Select Event Category']
) ?>

<?= $form->field($model, 'title')->textInput(['maxlength' => true]) ?>
   <?php
      if ($model->isNewRecord){
        echo $form->field($model2,'address')->textInput(['class' => 'placepicker form-control'])->label('Location');
    }
    else
        echo $form->field($model,'location')->textInput(['class' => 'placepicker form-control']);

?>

<di"form-group">
        <?= Html::submitButton($model->isNewRecord ? 'Create' : 'Update',     ['class' => $model->isNewRecord ? 'btn btn-danger' : 'btn btn-primary']) ?>
</div>

<?php ActiveForm::end(); ?>

现在的问题似乎是，在保存部分时抛出 error 说 unknown property address 因为该字段在数据库中不存在 table Event 我只希望该数据显示在我的 create form

的位置字段中

所以我在这里应该做什么

这里是table结构

Organiser          Event 
organiser_id       event_id
username           organiser_id 
clubname           title
image              location
email
firstname
lastname    
address

错误页面是这样写的

Unknown Property – yii\base\UnknownPropertyException

Getting unknown property: common\models\Event::address

这是我的 Event 模型

class Event extends \yii\db\ActiveRecord
{

    public static function tableName()
    {
      return 'event';
    }


public function rules()
{
    return [
        [['organiser_id', 'interest_id', 'title', 'location'], 'required'],
        [['organiser_id', 'interest_id'], 'integer'],
        [['title', 'location'], 'string', 'max' => 255],
    ];
}

/**
 * @inheritdoc
 */
public function attributeLabels()
{
    return [
        'id' => 'ID',
        'organiser_id' => 'Organiser ID',
        'interest_id' => 'Event Type',
        'title' => 'Event Title',
        'location' => 'Location'

    ];
}


public function getOrganiser()
{
    return $this->hasOne(User::className(), ['organiser_id' => 'organiser_id']);
}

}

这是我的 User 模型代表 Organiser table 和前端模型中的模型名称 SignUp.php

   class SignupForm extends Model
{
public $username;
public $address;
public $password;
public $password_repeat;



public function rules()
{
    return [
        ['username', 'filter', 'filter' => 'trim'],
        ['username', 'required'], 
        ['address', 'required'],
        ['username', 'unique', 'targetClass' => '\common\models\User', 'message' => 'This username has already been taken.'],
        ['username', 'string', 'min' => 2, 'max' => 255],


        [['file'], 'file', 'extensions'=>'jpg, gif, png'],



        ['password', 'required'],
        ['password', 'string', 'min' => 6],

        ['password_repeat', 'compare', 'compareAttribute' => 'password'],
    ];
}

public function attributeLabels()
{
    return [
        'password_repeat' => 'Confirm Password',
        'address' => 'Address',
        'username' => 'Username',
    ];
}



public function signup()
{
    if ($this->validate()) {
        $user = new User();
        $model = new SignupForm();
        $user->address = $this->address;
        $user->username = $this->username;

        $user->setPassword($this->password);
        $user->generateAuthKey();
        if ($user->save()) {
            return $user;
        }
    }

    return null;
}

}

所以我想在字段 Create event 的 Create event 表单上显示 organiser.address location 希望你现在能明白谢谢

Answer 1

可能你的函数应该看起来像

public function actionCreate()
{
    $event= new Event();

    $user= $this->findModel2(Yii::$app->user->id);
    $event->location = $user->address;

    if ($event->load(Yii::$app->request->post()) && $event->save()) {//active can set by default validator
        return $this->redirect(['view', 'id' => $event->id]);
    }
    return $this->render('create', [
        'event' => $event
    ]);

}

并且在表单中，您始终会显示位置。然后您可以在更新和创建中使用它，而无需查看 ifs。希望这会帮助你。
