我有一个名为Taluka模型。我应该选择区域并为该特定区域输入尽可能多的talukas。每个东西都在工作，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。我还试图在Yii2 Insert multiple records of a same table如何插入多次在单个表的属性值中yii2
给出的解决办法，而我接收到的错误是
模型 “上阵列呼叫到isAttributeRequired一个成员函数（）”：
<?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']],
];
}
/**

public function attributeLabels()
{
return [
'TalukaId' => 'Taluka ID',
'DistrictId' => 'District',
'talukas' => 'Taluka',
