laravel關係的表

Question

我有4個表：

用戶（ID，ROLE_ID）

角色（ID）

permission_role（ROLE_ID，permission_id）

許可（ID，姓名）

用戶模型

<?php 

namespace App; 

use Illuminate\Notifications\Notifiable; 
use Illuminate\Foundation\Auth\User as Authenticatable; 
use Zizaco\Entrust\Traits\EntrustUserTrait; 

class User extends Authenticatable 
{ 
    use Notifiable; 
    use EntrustUserTrait; 

    /** 
    * The attributes that are mass assignable. 
    * 
    * @var array 
    */ 
    protected $fillable = [ 
     'name', 'email', 'password', 
    ]; 

    /** 
    * The attributes that should be hidden for arrays. 
    * 
    * @var array 
    */ 
    protected $hidden = [ 
     'password', 'remember_token', 
    ]; 
    public function roles() 
{ 
    return $this->hasOne('App\Role', 'id', 'role_id'); 
} 
} 

榜樣

<?php 

namespace App; 

use Illuminate\Database\Eloquent\Model; 
use Zizaco\Entrust\EntrustRole; 

class Role extends EntrustRole 
{ 
    public function users() 
{ 
    return $this->belongsTo('App\User','role_id','id'); 
} 
public function permissions() 
    { 
     return $this->belongsToMany('App\Permission','permission_role'); 
    } 
} 

權限模型：

<?php 

namespace App; 

use Illuminate\Database\Eloquent\Model; 
use Zizaco\Entrust\EntrustPermission; 

class Permission extends EntrustPermission 
{ 
    public function roles() 
    { 
     return $this->belongsToMany('App\Role','permission_role'); 
    } 
} 

，我想在我的控制器進行測試，看是否通過用戶如果條件有權限delete_article，任何幫助嗎？並感謝

Answer 1

在你角色模型 像這樣的事情，你需要做的（多對多）

//....................... 
public function permissions() 
{ 
    return $this->belongsToMany('App\Permission','permission_role''role_id', 'permission_id'); 
} 
//...................... 

見多對多關係：Link

並獲取數據進入你的控制器

//.......................................... 
$user = get data with role and permission 
$roles= $user->roles; 
foreach($roles as $role){ 
    foreach($role->permissions as $permission){ 
     $permissiona_name = $permission->name; 
    } 
} 
//........................... 

用的var_dump（$用戶）首先檢查

Many to many with pivot（見Retrieving Intermediate Table Columns部分）

return $this->belongsToMany('App\Role')->withPivot('column1', 'column2');
