我在yii2有一个模型

<?php

namespace app\models;

/**

class CarAd extends \yii\db\ActiveRecord
{
    public $imageFiles;
    /**
     * @inheritdoc
     */
    public static function tableName()
    {
        return 'car_ad';
    }

    /**

    public function rules()
    {
        return [
            [['brand_id', 'sub_brand_id', 'sell_type', 'year', 'used_value', 'fuel_type_id', 'gearbox', 'body_status_id', 'body_color_id', 'number_type', 'ad_type_id', 'provice_id', 'city_id', 'address', 'lang', 'lat', 'creation_date', 'user_id'], 'required'],

        ];
    }

    public function upload()
    {   

        foreach ($this->imageFiles as $file) {
            $image = New CarAdImage();            
            $image->image = $file->baseName . '.' . $file->extension;
            $image->car_ad_id = $this->id;
            $image->save();
            $file->saveAs('img/car_ad/' . $file->baseName . '.' . $file->extension);
        }        
    }

    /**

    public function attributeLabels()
    {
        return [
            'id' => '?????', 'brand_id' => '????', 'sub_brand_id' => '???','sell_type' => '???? ?? ????',
            'year' => '???','used_value' => '??????','fuel_type_id' => '????? ????','gearbox' => '??????',
            'sell_mode' => '??? ????','real_price' => '???? ????','prepayment' => '??? ??????','installment_price' => '???? ?? ???','no_installments' => '????? ?????','delivery_time_id' => '???? ?????',

            'imageFiles' => '?????? ????'
        ];
    }
}

当我想提交我面对此错误的表单时.

Getting unknown property: app\models\CarAd::used_value

但正如你所看到我在我的领域有这个领域.我的表名是car_ad.我的代码有什么问题？

Answer 1

因为@property注释中没有此字段,我猜您在生成模型后添加了它.如果已缓存数据库模式,则在更新缓存之前不会获取新字段.尝试删除DB的缓存.
