はじめに

Laradoc に jenssegers/mongodb をサブデータベースとして導入する手順です。
多分メインデータベースとしてもマイグレーションすればいけるとは思う。

config/database.php

    'connections' => [
        'mongodb' => [
            'driver'   => 'mongodb',
            'host'     => 'xxx.xx.xx.xxx',
            'port'     => 27017,
            'database' => 'xxxx',
        ],

忘れずに MongoDB サーバのポートに穴を開けておきましょう

Model

<?php
namespace App\Model;

use Jenssegers\Mongodb\Eloquent\Model as Eloquent;

class XXXXXXModel extends Eloquent
{
        protected $connection = 'mongodb';
        protected $collection = 'xxxxx_collection';
        public $timestamps = false;
}

ObjectId

mongoDBでは頻繁にObjectIdを使用するが、

$acc = Account::where('mail','=','hoge@hoge.com'))->first();

ここでの $acc->_id は　ObjectId クラスじゃなく、文字列型のようです。
逆に、クエリビルダで ObjectId を検索する場合は、

$grid->model()->where('account_id','=',new \MongoDB\BSON\ObjectId('59a8358ab92fc626f2295340'));

のように \MongoDB\BSON\ObjectId クラスを作ってあげないとヒットしません。
