This package can be used in Laravel 5.8 or higher.
This package uses Laravel's Gate layer to provide Authorization capabilities.
The Gate/authorization layer requires that your `User` model implement the `Illuminate\Contracts\Auth\Access\Authorizable` contract.
Otherwise the `can()` and `authorize()` methods will not work in your controllers, policies, templates, etc.
In the `Installation` instructions you'll see that the `HasRoles` trait must be added to the User model to enable this package's features.
Thus, a typical basic User model would have these basic minimum requirements:
```php
use Illuminate\Foundation\Auth\User as Authenticatable;
use Spatie\Permission\Traits\HasRoles;
class User extends Authenticatable
{
use HasRoles;
// ...
}
```
Additionally, your `User` model/object MUST NOT have a `role` or `roles` property (or field in the database), nor a `roles()` method on it. Those will interfere with the properties and methods added by the `HasRoles` trait provided by this package, thus causing unexpected outcomes when this package's methods are used to inspect roles and permissions.
Similarly, your `User` model/object MUST NOT have a `permission` or `permissions` property (or field in the database), nor a `permissions()` method on it. Those will interfere with the properties and methods added by the `HasPermissions` trait provided by this package (which is invoked via the `HasRoles` trait).
