Question

我们正在尝试对某种语言进行验证，但我们正在尝试的是在xtext中编写语言和验证的skeltons（根本不使用xtend）是否可以单独使用xtext语言验证，即不使用xtend。提前致谢

你的Xtext语法应该是递归的，类似的东西：

<?php

namespace app\models;

use Yii;
use app\models\CDbExpression;

/**
 * This is the model class for table "reservations".
 *
 * @property integer $reservation_id
 * @property integer $schedule_id
 * @property integer $customer_id
 * @property integer $officer_id
 * @property integer $seat_number
 * @property string $amount_paid
 * @property string $datetime
 *
 * @property Customers $customer
 * @property User $officer
 * @property VehicleSchedules $schedule
 */
class Reservations extends \yii\db\ActiveRecord
{
    public $mobile_number;
    /**
     * @inheritdoc
     */
    public static function tableName()
    {
        return 'reservations';
    }

    /**
     * @inheritdoc
     */
    public function rules()
    {
        return [
            [['schedule_id', 'customer_id', 'officer_id', 'seat_number'], 'required'],
            [['schedule_id', 'customer_id', 'officer_id', 'seat_number'], 'integer'],
            [['amount_paid'], 'number'],
            [['datetime', 'mobile_number'], 'safe'],
            [['customer_id'], 'exist', 'skipOnError' => true, 'targetClass' => Customers::className(), 'targetAttribute' => ['customer_id' => 'customer_id']],
            [['officer_id'], 'exist', 'skipOnError' => true, 'targetClass' => User::className(), 'targetAttribute' => ['officer_id' => 'id']],
            [['schedule_id'], 'exist', 'skipOnError' => true, 'targetClass' => VehicleSchedules::className(), 'targetAttribute' => ['schedule_id' => 'schedule_id']],
        ];
    }

    /**
     * @inheritdoc
     */
    public function attributeLabels()
    {
        return [
            'reservation_id' => 'Ticket Number',
            'schedule_id' => 'Schedule ID',
            'customer_id' => 'Customer Name',
            'officer_id' => 'Officer',
            'seat_number' => 'Seat Number',
            'amount_paid' => 'Amount Paid',
            'datetime' => 'Date & Time',
            'mobile_number' => 'Mobile Number',
        ];
    }

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

    /**
     * @return \yii\db\ActiveQuery
     */
    public function getOfficer()
    {
        return $this->hasOne(Staff::className(), ['id' => 'officer_id']);
    }

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

是否可以单独使用xtext语言进行验证
