== How to fix it in Laravel

=== Code examples

==== Noncompliant code example

The ``++define++``, ``++before++``, and ``++after++`` methods of a https://laravel.com/docs/master/authorization#gates[Gate] are not compliant when they return only an affirmative decision (``++true++`` or ``++Response::allow()++``):

[source,php,diff-id=101,diff-type=noncompliant]
----
class NoncompliantGuard
{
    public function boot()
    {
        Gate::define('xxx', function ($user) {
            return true; // Noncompliant
        });

        Gate::define('xxx', function ($user) {
            return Response::allow(); // Noncompliant
        });
    }
}
----

==== Compliant solution

The ``++define++``, ``++before++``, and ``++after++`` methods of a https://laravel.com/docs/master/authorization#gates[Gate] should return a negative decision (``++false++`` or ``++Response::deny()++``) or abstain from making a decision (``++null++``):

[source,php,diff-id=101,diff-type=compliant]
----
class CompliantGuard
{
    public function boot()
    {
        Gate::define('xxx', function ($user) {
            if (foo()) {
                return true;
            }
            return false;
        });

        Gate::define('xxx', function ($user) {
            if (foo()) {
                return Response::allow();
            }
            return Response::deny();
        });
    }
}
