【问题描述】：

我正在使用 Eloquent 在我的 Laravel 应用程序中创建模型。我不确定我做了什么更改，但现在当我尝试创建 AppUser 的新实例时收到此错误：

Next exception 'Illuminate\Database\QueryException' with message 'SQLSTATE[42S02]: Base table or view not found: 1146 Table 'gonote.appusers' doesn't exist (SQL: select count(*) as aggregate from `appUsers` where `email` = user-4720@gonote.co)' in /Users/james/projects/GoNote/laravel/vendor/laravel/framework/src/Illuminate/Database/Connection.php:647

查询失败是有道理的，因为表名为app_users 而不是appUsers。但是，我对所有查询都使用 Eloquent，所以我没有手写任何内容。我尝试将protected $table = 'app_users' 添加到我的AppUser 模型类中，但它似乎仍在查询错误的表。

这是创建模型的函数：

protected function create(array $fields)
{
    return AppUser::create([
        'email' => $fields['email'],
        'name' => $fields['name'],
        'photo' => $fields['photo'],
        'phone' => $fields['phone'],
        'password' => bcrypt($fields['password'])
    ]);
}

模型/AppUser.php

<?php

namespace App\Models;

use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Database\Eloquent\Model;
use Backpack\CRUD\CrudTrait;
use Laravel\Passport\HasApiTokens;

class AppUser extends Authenticatable
{
    use CrudTrait, HasApiTokens;

    protected $table = 'app_users';
    //protected $primaryKey = 'id';
    // public $timestamps = false;
    // protected $guarded = ['id'];
    protected $fillable = ['email', 'password', 'name', 'photo', 'phone', 'api_token'];
    protected $hidden = ['password'];
    // protected $dates = [];

    /*
    |--------------------------------------------------------------------------
    | FUNCTIONS
    |--------------------------------------------------------------------------
    */
    public function getAuthIdentifier() {
        return $this->getKey();
    }

    public function getAuthPassword() {
        return $this->password;
    }

    public function findForPassport($username) {
        return $this->where('email', $username)->first();
    }
}

【问题讨论】：

当您将protected $table = 'app_users' 添加到您的模型时，您会收到与您的问题中的错误消息相同的错误消息吗？
@jackel414 添加不会改变任何东西。我也粘贴了错误的错误。我在帖子中更正了。
您可以粘贴您的型号代码吗？如果它很大，则不是所有内容 - 只是声明和相关方法
当然。已将其添加到帖子中。

【解决方案1】：

看起来问题是由验证引起的 - 失败的查询似乎是唯一的验证器。检查您在哪里对电子邮件地址进行唯一验证并正确传递表名。

【讨论】：

添加评论，因为这个答案引导我走向正确的方向。在进行功能测试时，assertDatabaseHas 还需要正确的表名。我打错了一个字符并返回同样的错误。

【解决方案2】：

查看堆栈跟踪。您正在添加一个新用户，并且有一个 Validator 和 email|unique:appUsers 规则。您只需在此处修复表名即可。

    return Validator::make($data, [
        'name' => 'required|max:255',
        'email' => 'required|email|max:255|unique:app_users', // here
        'password' => 'required|min:6|confirmed',
    ]);

这就是问题所在。谢谢你。我接受了另一个答案，因为他的发布时间稍早。
