Question

我有一个名叫Taluka的模特。我应该选择区，并为该特定区域输入尽可能多的talukas。每件事都有效，但是当我输入多个talukas时，只有最后一个taluka被保存在数据库表中。我也尝试过Yii2 Insert multiple records of a same table

中给出的解决方案

但我收到的错误是＆＃34;在数组＆＃34上调用成员函数isAttributeRequired（）;

型号：

<?php

namespace app\models;

use Yii;

/**
 * This is the model class for table "taluka".
 *

*/

class Taluka extends \yii\db\ActiveRecord
{
    /**
     * @inheritdoc
     */


public $talukas=[];

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

/**
 * @inheritdoc
 */
public function rules()
{
    return [
        [['DistrictId', 'Taluka'], 'required'],
        [['DistrictId'], 'integer'],
        [['talukas'], 'required'],
        [['Taluka'], 'string', 'max' => 100],
        [['DistrictId'], 'exist', 'skipOnError' => true, 'targetClass' => District::className(), 'targetAttribute' => ['DistrictId' => 'DistrictId']],
    ];
}

/**
 * @inheritdoc
 */
public function attributeLabels()
{
    return [
        'TalukaId' => 'Taluka ID',
        'DistrictId' => 'District',
        'talukas' => 'Taluka',
    ];
}


/**
 * @return \yii\db\ActiveQuery
 */
 public function getDistrict()
 {
     return $this->hasOne(District::className(), ['DistrictId' => 'DistrictId']);
  }
}

Answer 1

首先，让我们了解为什么会出现错误"Call to a member function isAttributeRequired() on array"。原因在于rules方法：

public function rules()
{
    return [
        [['DistrictId', 'Taluka'], 'required'],
        [['DistrictId'], 'integer'],
        [['talukas'], 'required'],// <-- This line causes an error. Reqired filed in ActiveRecord model could not be an array.
        [['Taluka'], 'string', 'max' => 100],
        [['DistrictId'], 'exist', 'skipOnError' => true, 'targetClass' => District::className(), 'targetAttribute' => ['DistrictId' => 'DistrictId']],
    ];
}

因此，最好从[['talukas'], 'required']中移除rules()。这是一个自定义字段，因此ActiveRecord逻辑不会检查它。

此外，actionCreate()中存在一个奇怪的逻辑。请注意，您已根据模型Taluka向模型中添加了自定义字段，并且未填写rules()，这是必需的。因此，您不能只将$_POST加载到模型中，并需要遍历talukas为每个创建一条新记录：

public function actionCreate()
{
    $model = new Taluka();
    if ($model->load(Yii::$app->request->post())) {

        $talukaList = $model->talukas;

        if (is_array($talukaList)) {
            foreach ($talukaList as $taluka) {
                $talukaRecord = new Taluka();
                $talukaRecord->DistrictId = $model->DistrictId;
                $talukaRecord->Taluka = $taluka;
                $talukaRecord->save();
            }
        }
        return $this->redirect(['view', 'id' => $talukaRecord->TalukaId]);
    } else {
        return $this->render('create', [
            'model' => $model,
        ]);
    }
}

我假设TalukaId是一个自动增量主键。保存所有记录后，它会将您重定向到最后创建的taluka。
