我需要帮助才能从数据库中的用户、角色和权限之间的关系获取数据。请看下面...
数据库:
用户
id name role_id
1 Phil 1
2 Rob 1
3 Dave 2
用户角色
id name
1 Admin
2 Staff
权限
id endpoint
1 /users
2 /roles
用户角色权限
user_role_id permissions_id
1 1
1 2
1 2
从用户模型中，我希望能够从权限表中获取数据，这样我就知道用户拥有什么访问权限。
这是模型:
用户.php
class User extends Model implements AuthenticatableContract, AuthorizableContract
{
use Authenticatable, Authorizable, SoftDeletes;
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [
'name', 'role_id'
];
/**
* The attributes excluded from the model's JSON form.
*
* @var array
*/
protected $hidden = [
'password',
];
protected $dates = [
'deleted_at'
];
public function role()
{
return $this->belongsTo('App\User');
}
public permissions()
{
?????
}
}
用户角色.php
class UserRole extends Model {
protected $fillable = ['name'];
protected $hidden = [];
public function users()
{
return $this->hasMany('App\User');
}
public function permissions()
{
return $this->belongsToMany('App\Permission', 'user_role_permissions');
}
}
权限.php
class Permission extends Model {
protected $fillable = ['endpoint'];
protected $hidden = [];
public function roles()
{
return $this->belongsToMany('App\UserRoles','user_role_permissions');
}
}
请帮忙!
最佳答案
您已正确定义了所有必需的关系。您可以像这样使用它:
User::with('role.permissions')->first();
// It gives you all the permissions that are assigned to the role assigned to the underlying user :)
// Pretty vague to explain though
您不需要在 User 模型上定义 permission()。
