Laravel - Authorization - Policy Auto Discovery

Instead of manually registering model policies, Laravel can automatically discover policies as long as the model and policy follow standard Laravel naming conventions. Specifically, the policies must be in a Policies directory at or above the directory that contains your models. So, for example, the models may be placed in the app/Models directory while the policies may be placed in the app/Policies directory. In this situation, Laravel will check for policies in app/Models/Policies then app/Policies. In addition, the policy name must match the model name and have a Policy suffix. So, a User model would correspond to a UserPolicy policy class.

If you would like to define your own policy discovery logic, you may register a custom policy discovery callback using the Gate::guessPolicyNamesUsing method. Typically, this method should be called from the boot method of your application's AuthServiceProvider:

    
    use Illuminate\Support\Facades\Gate;
    
    Gate::guessPolicyNamesUsing(function ($modelClass) {
        // Return the name of the policy class for the given model...
    });
	
Any policies that are explicitly mapped in your AuthServiceProvider will take precedence over any potentially auto-discovered policies.
