laravel 中使用mongodb創建Model並使用

創建Model文件：

<?php

namespace App\Models;

use Jenssegers\Mongodb\Eloquent\Model as Moloquent; 
use DB;

class UserMongo extends Moloquent {  //繼承的不是普通的model，而是Mongo中的Model

    protected $connection = 'mongodb';  //使用mongodb

    protected $collection = 'userInfo';
    protected $primaryKey = '_id';

    protected $fillable = [];
    protected $guarded = [];
}

其他類中使用：

<?php
namespace App\Services;

use App\Models\UserMongo;
use App\User;

class UserService {

    private $mongoUser;

    
    public function setUserInfo($user) {
        //查詢
        $info = UserMongo::where('id', $user['id'])->get();
        if(count($info)>0) {
            //修改
            UserMongo::where('id', $arr_user['id'])->update($user);
        } else {
            //新增
            UserMongo::insert($user);
        }
    }
}
