laravel 關(guān)聯(lián)模型報(bào)錯(cuò)！failed to open stream

數(shù)據(jù)庫

用戶表:

• id
• name
• password
• email

客訴表:

• id
• title
• content
• uid *關(guān)聯(lián)user表id*

客訴日志表:

• id
• text
• cc_id *關(guān)聯(lián)客訴id*

Rma 模型

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Rma extends Model
{
    /**
     * Rename table name.
     * @var string
     */
    protected $table = 'oacustomercomplaint';

    /**
     * The attributes that are mass assignable.
     * @var array
     */
    protected $fillable = [];

    /**
     * 關(guān)聯(lián)rma日志記錄
     * @return \Illuminate\Database\Eloquent\Relations\HasMany
     */
    public function logs()
    {
        return $this->hasMany('App\Models\Rmalog', 'cc_id');
    }

    /**
     * 關(guān)聯(lián)user表
     * @return \Illuminate\Database\Eloquent\Relations\HasOne
     */
    public function user()
    {
        return $this->belongsTo('App\User', 'uid');
    }
}

Rma 控制器

public function getRmaList(){
    $rmas = Rma::with('user')->orderBy('cc_time', 'desc')->get();
    return $rmas;
}

User model我是獨(dú)立放在app目錄下面的
其它的模型都在models目錄下

User 模型

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class User extends Model
{
    /**
     * Rename table name.
     * @var string
     */
    protected $table = 'user';

    /**
     * All fields can be written.
     * @var array
     */
    protected $guarded = [];

    /**
     * Hidden fields.
     * @var array
     */
    protected $hidden = [
        'password'
    ];
}

當(dāng)我試圖關(guān)聯(lián)user模型獲取用戶數(shù)據(jù)時(shí)出現(xiàn)了以下錯(cuò)誤：

(1/1) ErrorException
include(/Library/WebServer/Documents/LaravelOA): failed to open stream: Undefined error: 0

我以為是權(quán)限問題，我試圖將項(xiàng)目目錄的權(quán)限改為777，似乎也沒用。
可是我關(guān)聯(lián)logs日志表的時(shí)候獲取的數(shù)據(jù)又是正常的，求大佬解答
