请问老师，上述代码，机加件表里的数据咋显示不出来呢，$count=0，数据获取不到，同样的代码，另外一个表就没事

<?php

namespace app\index\model;

use think\Model;
use traits\model\SoftDelete;

class Gongyika extends Model

//引用软删除方法集

protected $dateFormat = 'Y/m/d';

//定义表中的删除时间字段,来记录删除时间
protected $deleteTime = 'delete_time';

// 开启自动写入时间戳
protected $autoWriteTimestamp = true;

protected $createTime = 'create_time';

protected $updateTime = 'update_time';

    protected $type = [
        'start_time'=>'timestamp',
    ];

public function jijiajian()
    {
        // 班级表与教师表是1对1关联
        return $this->hasOne('jijiajian');
    }
