php - Laravel 5.2 - 使用字符串作为 Eloquent 表的自定义主键变为 0

Question

我正在尝试使用电子邮件作为我表的主键，所以我 Eloquent 代码是-

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class UserVerification extends Model
{
    protected $table = 'user_verification';
    protected $fillable =   [
                                'email',
                                'verification_token'
                            ];
    //$timestamps = false;
    protected $primaryKey = 'verification_token';
}

我的数据库是这样的-

但如果我这样做-

UserVerification::where('verification_token', $token)->first();

我收到了-

{
  "email": "sdfsdf@sdfsdf.sdf",
  "verification_token": 0,
  "created_at": "2016-01-03 22:27:44",
  "updated_at": "2016-01-03 22:27:44"
}

所以，验证 token /主键变为0。

有人可以帮忙吗？

这是 added to the upgrade documentation on Dec 29, 2015 ，所以如果你之前升级过，你可能会错过它。

从模型中获取任何属性时，它会检查该列是否应转换为整数、字符串等。

默认情况下，对于自增表，此方法中ID假定为整数:

https://github.com/laravel/framework/blob/5.2/src/Illuminate/Database/Eloquent/Model.php#L2790

所以解决办法是:

class UserVerification extends Model
{
    // if your key name is not 'id'
    // you can also set this to null if you don't have a primary key
    protected $primaryKey = 'your_key_name';

    public $incrementing = false;

    // In Laravel 6.0+ make sure to also set $keyType
    protected $keyType = 'string';
}
