我有 app / User.php 的用户模型类，namespace App;。此外， config / auth.php 将其标记为'model' => App\User::class。
尽管如此，我的一个控制器似乎仍然存在其命名空间导入问题。下面的控制器文件将在Model.php第765行中引发＆＃34; FatalErrorException：Class＆＃39; App / User＆＃39;如果调用orderProduct函数，则找不到＆＃34; 异常。尽管使用了User类，但调用product函数不会抛出相同的错误。我想知道错误是否与导入有关，而更多的是与User类有关，不喜欢将它与OrderHeader模型关联的尝试。

值得注意的是，AuthController与此控制器具有相同的导入功能，但在登录时没有任何问题。
<?php

use Illuminate\Foundation\Auth\AuthenticatesAndRegistersUsers;

*/
use AuthenticatesAndRegistersUsers;
/**
* Create a new authentication controller instance.
*
* @return void
*/
public function __construct()
{
$this->middleware('guest', ['except' => 'getLogout']);
}
protected $redirectPath = '/home';
/**

protected function validator(array $data)
{
return Validator::make($data, [
'name' => 'required|max:255',
'email' => 'required|email|max:255|unique:users',
'password' => 'required|confirmed|min:6',
]);
}
/**

*/
protected function create(array $data)
{
return User::create([
'name' => $data['name'],
'email' => $data['email'],
'password' => bcrypt($data['password']),
]);
}
}
为了您的利益，用户模型的内容：

OrderHeader模型。
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Relations\HasMany;
class OrderHeader extends Model
{
//
protected $table = 'OrderHeader';
protected $primaryKey = 'OrderID';
protected $fillable = array('ShippingID');
public function orderDetails(){
return $this->hasMany('App\OrderDetail','OrderHeaderID','OrderID');
}
public function shippingAddress(){
return $this->belongsTo("App/Shipping", 'ShippingID', 'ShippingID');
}
public function user(){
return $this->belongsTo("App/User", 'id', 'OrderID');
}
}
（另一方面，如果您在ProductController中发现任何其他潜在错误，请告诉我 - 由于系统中的其他问题导致无法测试，我必须编写很多我的第一个真正的控制器而不进行测试。）
答案 0 :(得分：2)
您的user()和shippingAddress()关系使用了错误的斜杠。
return $this->belongsTo("App/User", 'id', 'OrderID');
应该是：
return $this->belongsTo("App\User", 'id', 'OrderID');
