Typically, gates are defined within the boot method of the App\Providers\AuthServiceProvider class using the Gate facade. Gates are simply closures that determine if a user is authorized to perform a given action. Gates are a great way to learn the basics of Laravel's authorization features however, when building robust Laravel applications you should consider using policies to organize your authorization rules. In contrast, policies should be used when you wish to authorize an action for a particular model or resource. Most applications will most likely contain some mixture of gates and policies, and that is perfectly fine! Gates are most applicable to actions that are not related to any model or resource, such as viewing an administrator dashboard. You do not need to choose between exclusively using gates or exclusively using policies when building an application. In this documentation, we'll explore gates first and then examine policies. Gates provide a simple, closure-based approach to authorization while policies, like controllers, group logic around a particular model or resource. Think of gates and policies like routes and controllers. Laravel provides two primary ways of authorizing actions: gates and policies. Laravel's authorization features provide an easy, organized way of managing these types of authorization checks. For example, even though a user is authenticated, they may not be authorized to update or delete certain Eloquent models or database records managed by your application. In addition to providing built-in authentication services, Laravel also provides a simple way to authorize user actions against a given resource.
