Userpermission pivot-function is only accessible via the Auth class

I have a simple Userpermission System consisting of 3 tables: users, permissions and the pivot table permission_user.

This is the User model:

<?php

namespace App;

use IlluminateContractsAuthMustVerifyEmail;
use IlluminateFoundationAuthUser as Authenticatable;
use IlluminateNotificationsNotifiable;

class User extends Authenticatable
{
    use Notifiable;

    /**
     * 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',
    ];

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];

    public function permissions()
    {
        return $this->belongsToMany('AppPermission');
    }

}

and here is the Permission Model:

<?php

namespace App;

use IlluminateDatabaseEloquentModel;

class Permission extends Model
{
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'description', 'level', 'parentpermission',
    ];

    public function users()
    {
        return $this->belongsToMany('AppUser');
    }


}

Now when I try to get all the permissions of the currently logged in user with this:

 $user_permissions = Auth::user()->permissions()->get();

it works without problems.

But when I try to get another Users Permissions like this:

$user_permissions = User::where('id', '=', $userid)->permissions()->get();

I get the following error:

Method IlluminateDatabaseEloquentCollection::permissions does not exist.

How do I proceed?

Answer

I think you’re missing first() here, since you can’t get relations of a query builder object. Try this :

$user_permissions = User::where('id', '=', $userid)->first()->permissions()->get();

This first() will actually return User object, and then you can load its relations.
