Question

我有用户和用户组表。

在用户表中，它包含：id，name，email，usergroup_id [fk]

在usergroup表中，它包含：id [pk]，usergroup

对于名字，我可以这样：

{{Auth::User()->name}}

usergroup.usergroup怎么样？

Answer 1

您可以为此创建关系one to many。

user.php的的

public function userGroup(){
 $this->belongsTo('Usergroup');
}

Usergroup.php

public function users(){
 $this->hasMany('User');
}

现在你可以通过以下方式获得：

Auth::user()->userGroup->usergroup;

它可能有效：）

Answer 2

用户模型：

// here we saying that User belongs to a User group 
public function userGroup(){
     return $this->belongsTo(UserGroup::class,'usergroup_id');
}

UserGroup Model：

// here we saying that User group has many users 
public function user(){
    return $this->hasMany(User::class,'usergroup_id','id');
}

从用户对象中可以执行以下操作：

$userGroupObj = Auth::user()->userGroup();
// this would be a userGroup Object
// so now to get usergroup you can do
$userGroup = $userGroupObj->usergroup;

// Please make sure you check if($userGroupObj) before doing $userGroup = $userGroupObj->usergroup;

// So I would do something like
$userGroup = null;
$userGroupObj = Auth::user()->userGroup();
if($userGroupObj){
    $userGroup = $userGroupObj->usergroup;  
}

您可以从UserGroupObject执行以下操作：

$userObjCollection = $userGroupObject->user();
// this would be a user collection giving you all users in that group.

加入Auth :: User Laravel 4的其他表
