Laravel’s Inertia is a popular tool for building modern, fast, and reactive applications. However, when it comes to implementing authorization policies, many developers encounter an issue where the “policy deny after login” feature does not work as expected. In this article, we’ll dive deep into the problem, explain why it happens, and provide a step-by-step guide to troubleshooting and resolving this issue.
The Problem: Policy Deny After Login Does Not Work with Inertia
When using Inertia with Laravel, you might have noticed that after a user logs in, the policy deny feature no longer works as intended. This means that even if a user doesn’t have the necessary permissions to access a specific route or resource, they can still access it. This is a major security concern and can lead to unauthorized access to sensitive data.
Why Does This Happen?
The reason for this behavior lies in how Inertia handles requests and responses. When a user logs in, Inertia stores the authenticated user’s data in the session. However, when a request is made to a protected route, Inertia doesn’t re-authenticate the user or re-validate their permissions. Instead, it relies on the initial authentication data stored in the session. This means that even if a user’s permissions change or they’re denied access to a resource, Inertia won’t pick up on these changes.
Troubleshooting and Resolution
Don’t worry; there are ways to troubleshoot and resolve this issue. Follow these steps to get your policy deny feature working again:
Step 1: Verify Your Policy Implementation
First, make sure you’ve implemented your policies correctly. Check that you’ve registered your policies in the `AuthServiceProvider` and that you’re using the correct middleware in your route definitions.
<?php
namespace App\Providers\AuthServiceProvider;
use Illuminate\Support\Facades\Gate;
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;
class AuthServiceProvider extends ServiceProvider
{
/**
* The policy mappings for the application.
*
* @var array
*/
protected $policies = [
'App\Model' => 'App\Policies\ModelPolicy',
];
/**
* Register any authentication / authorization services.
*
* @return void
*/
public function boot()
{
$this->registerPolicies();
}
}
Step 2: Update Your Middleware
Next, update your middleware to re-authenticate the user and re-validate their permissions on each request. You can do this by creating a custom middleware that wraps the `Illuminate\Auth\Middleware\Authorize` middleware.
<?php
namespace App\Http\Middleware;
use Illuminate\Auth\Middleware\Authorize;
use Illuminate\Support\Facades\Auth;
class ReAuthenticateMiddleware
{
public function handle(Request $request, Closure $next)
{
// Re-authenticate the user
Auth::authenticate();
// Re-validate permissions
$this->authorizeMiddleware->handle($request, $next);
return $next($request);
}
}
Step 3: Register the Custom Middleware
Register your custom middleware in the kernel:
<?php
namespace App\Http;
use Illuminate\Foundation\Http\Kernel as HttpKernel;
class Kernel extends HttpKernel
{
/**
* The application's route middleware groups.
*
* @var array
*/
protected $middlewareGroups = [
'web' => [
// ...
\App\Http\Middleware\ReAuthenticateMiddleware::class,
],
];
}
Step 4: Update Your Inertia Configuration
Finally, update your Inertia configuration to use the custom middleware:
<?php
namespace App\Providers;
use Inertia\InertiaMiddleware;
class InertiaServiceProvider extends ServiceProvider
{
public function boot()
{
Inertia::version('3.0');
Inertia::middleware([
// ...
\App\Http\Middleware\ReAuthenticateMiddleware::class,
]);
}
}
Conclusion
In conclusion, the “policy deny after login” feature not working with Inertia in Laravel is a common issue that can be resolved by following the steps outlined above. By re-authenticating the user and re-validating their permissions on each request, you can ensure that your application’s authorization policies are enforced correctly. Remember to verify your policy implementation, update your middleware, register the custom middleware, and update your Inertia configuration.

Frequently Asked Question
Get the scoop on the most pressing questions about policy deny after login not working with Inertia in Laravel.
What is the main reason why policy deny after login doesn’t work with Inertia in Laravel?
The primary culprit behind this issue is Inertia’s client-side rendering, which bypasses Laravel’s middleware stack, including the policy checks. This means that the policy deny after login feature is not triggered, allowing unauthorized access.
How can I troubleshoot this issue and identify the root cause?
To troubleshoot this issue, enable debug mode in Laravel, inspect the request and response data, and review the Inertia request lifecycle. You can also use tools like Laravel Debugbar or Clockwork to gain more insights into the request-processing pipeline.
Can I use a middleware to enforce policy checks in Inertia requests?
Yes, you can create a custom middleware that checks the policy and denies access if necessary. However, this approach requires careful implementation to ensure that the middleware is executed correctly in the Inertia request lifecycle.
Are there any workarounds or alternative solutions to this issue?
One possible workaround is to use JavaScript-based authorization checks in your Inertia components. This approach can provide a decent level of security, but it’s essential to implement it correctly to avoid security vulnerabilities.
Is there an official solution or fix from the Laravel or Inertia teams for this issue?
Currently, there is no official fix or solution from the Laravel or Inertia teams for this specific issue. However, the community is actively discussing and exploring ways to resolve this problem, so keep an eye on the official forums and GitHub issues for updates.
