Laravel Limit user by subscription plan

@stephanegadzhev A policy is probably the best place, given you have the authenticated user instance (the user trying to create the resource) and the resource type to hand:

use App\Models\User;
use Illuminate\Auth\Access\Response;

class LocationPolicy
{
    public function create(User $user)
    {
        $count = $user->locations()->count();

        $limit = match ($user->plan_id) {
            'plan-silver' => 10,
            'plan-gold' => 20,
        };

        return ($count < $limit)
            ? Response::allow()
            : Response::deny('You have exceeded your plan limit.');
    }
}

You can now just check if a user can create a location, knowing that plan limits will be automatically checked:

public function store(StoreLocationRequest $request)
{
    $this->authorize('create', Location::class);

    $user = $request->user();

    $location = $user->locations()->create($request->validated());

    // TODO: Return response
}

Or, if you’re using resource controllers, then you can just automatically authorise all actions so long as you’re sticking to Laravel’s conventions:

class LocationController extends Controller
{
    public function __construct()
    {
        $this->authorizeResource(Location::class);
    }

    public function create()
    {
        return view('locations.create');
    }

    public function store(StoreLocationRequest $request)
    {
        $user = $request->user();

        $location = $user->locations()->create($request->validated());

        // TODO: Return response...
    }
}
