Laravel Auth::user relationship
提问by El Hombre Sin Nombre
In Laravel, i′m trying to show relation elements between Auth::user(Users) and Departments. In Usertable i have id, name, and department_id. In Departmentstable I have idand name.
在Laravel 中，我试图显示Auth::user( Users) 和Departments之间的关系元素。在User表中，我有id、name和department_id。在Departments表中，我有id和name。
In user model i create
在我创建的用户模型中
public function department()
{
return $this->belongsTo('App\Models\Department');
}
Then, in blade template I try
然后，在刀片模板中我尝试
Auth::user()->department
Auth::user()->部门
But return null and doesn′t show linkeddepartments. Null is incorrect, all usershave departments. Soo, ?Any help? ?What′s wrong in relation?
但是返回 null 并且不显示链接的部门。Null 不正确，所有用户都有部门。有什么帮助吗？？有什么关系？

You should add 'department_id' as a second parameter ($foreignKey) when calling belongsTo method, because it will searching for departmento_id by default.
在调用belongsTo 方法时，您应该添加'department_id' 作为第二个参数（$foreignKey），因为它默认会搜索departmento_id。
public function departamento()
{
return $this->belongsTo('App\Models\Departamento', 'department_id');
}
Or just rename User::departamento() method to User::department()
或者只是将 User::departamento() 方法重命名为 User::department()
public function department()
{
return $this->belongsTo('App\Models\Departamento');
}

You can try this User::with('departmento')->find(Auth::id());
你可以试试这个 User::with('departmento')->find(Auth::id());

Relation works with Model. Auth uses the session it not uses relation
关系适用于模型。身份验证使用它不使用关系的会话
Use UserModel instead
改用User模型
optional(User::find(Auth::id())->departmento)->department_name
