Name: Policies Description: Centralised authorization logic for a given Eloquent model. Policies define per-ability access control and are enforced at the controller level. Compatible Agents: general-purpose, backend Tags: app/Policies/**/*.php, laravel, php, backend, policy, authorization, auth

Rules

  • Policy classes live in app/Policies/
  • Naming: PascalCase with a Policy suffix, named after the model they protect: InvoicePolicy, PostPolicy
  • Policies centralise all authorization logic for a given model in one place
  • Create one policy for each model
  • Define one method per ability — use standard names: viewAny, view, create, update, delete, restore, forceDelete
  • Always enforce authorization at the controller level — never inside actions or services
  • Laravel auto-discovers policies that follow the ModelPolicy naming convention
  • For custom locations, register manually in AuthServiceProvider

Examples

namespace App\Policies;

use App\Models\Invoice;
use App\Models\User;

class InvoicePolicy
{
    public function viewAny(User $user): bool
    {
        return $user->isAdmin();
    }

    public function view(User $user, Invoice $invoice): bool
    {
        return $user->id === $invoice->user_id || $user->isAdmin();
    }

    public function create(User $user): bool
    {
        return $user->hasVerifiedEmail();
    }

    public function update(User $user, Invoice $invoice): bool
    {
        return $user->id === $invoice->user_id && $invoice->isDraft();
    }

    public function delete(User $user, Invoice $invoice): bool
    {
        return $user->isAdmin();
    }
}

// Usage in controller
public function update(UpdateInvoiceRequest $request, Invoice $invoice): InvoiceResource
{
    $this->authorize('update', $invoice);
    // ...
}

// Usage in Form Request
public function authorize(): bool
{
    return $this->user()->can('update', $this->route('invoice'));
}

// Usage via route middleware
Route::put('/invoices/{invoice}', [InvoiceController::class, 'update'])
    ->middleware('can:update,invoice');

Anti-Patterns

  • Putting authorization logic directly in controllers, actions, or models
  • Creating global gates instead of model-specific policies when model-based auth is appropriate
  • Not creating a policy for each model
  • Putting business logic inside a policy method (belongs in Actions or Services)
  • Using return true in authorize() without documenting the intent
