Laravel attempt to read property on null

I’m using simple Gates user permissions on my Laravel.

I have a permissions table with hasOne relationship:

class User extends Authenticatable
{
 public function permissions()
    {
        return $this->hasOne(UserPermission::class);
    }
}

and in an AuthServiceProvider I have to register permission:

  public function boot()
    {
        $this->registerPolicies();

        Gate::define('is_admin', fn(User $user) => $user->permissions->is_admin);
        Gate::define('is_test_user', fn(User $user) => $user->permissions->is_test_user);

        //
    }

but when the record doesn’t exist in my permission table then I have an error: Attempt to read property "is_admin" on null.

What’s the best solution for this problem?

>Solution :

The optional helper is intended for this purpose.

optional($user->permissions)->is_admin
