Laravel 5.1“给予”；类别'；应用程序/用户'；“未找到”；尽管名称空间、config/auth.php和文件位置正确

我在app/User.php中有一个用户模型类，带有

名称空间app。另外，config/auth.php将其标记为
'model'=>App\User:：class

尽管如此，我的一个控制器的名称空间导入似乎仍然存在问题。如果调用
orderProduct
函数，下面的控制器文件将抛出“Model.php第765行中的FatalErrorException:类'App/User'not found”异常。调用
product
函数不会抛出相同的错误，尽管它使用了User类。我想知道错误是否与导入关系不大，而与不喜欢尝试将其与OrderHeader模型关联的用户类关系更大

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');

您的

你能发布完整的错误吗

return $this->belongsTo("App\User", 'id', 'OrderID');
