写入的行具有所有默认值（null、0 等）

Question

我正在使用 Laravel 5.1 并尝试将一行插入到通过 SSH 隧道连接的远程数据库中，并且读取正常。我有一个本地数据库和各种远程数据库。这段代码曾经可以工作，我只是在 DigitalOcean 中克隆了我的 droplet，以便它指向另一个远程数据库，然后问题就出现了。

当我创建远程 Promotion 时，我得到了一个主键 ID，但是当我读回它并在 MySQL Workbench 上检查它时，所有字段都有默认值，主要是 NULL 和 0。知道发生了什么吗？

以下配置适用于我正在尝试写入的远程数据库。

数据库配置

'prod' => [
    'read'      => [
        'options' => [
            PDO::MYSQL_ATTR_INIT_COMMAND => 'SET time_zone = \'-04:00\''
            ]
    ],
    'write'     => [],
    'driver'    => 'mysql',
    'host'      => env('PROD_DB_HOST', 'localhost'),
    'port'      => env('PROD_DB_PORT', '3306'),
    'database'  => env('PROD_DB_DATABASE', 'forge'),
    'username'  => env('PROD_DB_USERNAME', 'forge'),
    'password'  => env('PROD_DB_PASSWORD', ''),
    'charset'   => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix'    => '',
    'strict'    => false,
],

型号

<?php

namespace App\Models\Remote;

    protected $connection = null;
    protected $table = 'Tournament';
    protected $primaryKey = 'tournamentId';

    public $timestamps = false;

    public function __construct()

    }

    public function scopeActive($query)
    {
        return $query->where('status', 3);
    }

    foreach ($promo->assets as $a) {

        switch($a['assetTypeId']) {

            case 1:
                $data['eventFilePath'] = 'uploadfiles/tournament/event/'.$a['assetName'];
                $data['promoFilePath'] = 'uploadfiles/tournament/promo/'.$a['assetName'];
                break;
            case 2:
                $data['imageFilePath'] = 'uploadfiles/tournament/image/'.$a['assetName'];
                $data['thumbnailFilePath'] = 'uploadfiles/tournament/image/'.$a['assetName'];
                break;
            case 3:
                $data['iconFilePath'] = 'uploadfiles/tournament/icon/'.$a['assetName'];

            case 7:
                $data['ruleFilePath'] = 'uploadfiles/tournament/rule/'.$a['assetName'];
                break;
            default:
                break;
        }
    }

    foreach ($post['env'] as $env) {

        if ($env == 'dev') {

            $dev_promo = \PromotionRemote::create($data);

... //At this point I dumped $data and it had the right values but the entry had all null's and 0's and whatnot.

注意：\Promotion:: 是本地数据库的推广，我基本上是复制到远程数据库。

Answer 1

这成功了：

class Promotion extends Model
{
    ...

    public function __construct($attributes = [])
    {
        parent::__construct($attributes);        

        $this->connection = env('APP_ENV');
    }

    ...
}

因为我的类上有一个扩展 Eloquent 的 Model 的构造函数，所以在我做任何事情之前我还需要调用 Model 的构造函数。
