Model::findOrFail a lot in Laravel. Recently, I realized it’s not always the best option.
findOrFail is great because it ensures you’ll end up with a model instance. No more “Attempt to read property on null” exceptions.
$title = Post::findOrFail($id)->title;
Another benefit is that Laravel returns a 404 response for you when the model doesn’t exist. (This is handled in Laravel’s base exception handler) The 404 response is a double-edged sword. It’s a great feature in controllers and other outer layers of your application, but can be harmful in core business logic.
Validating that a model exists should generally happen in a request object or a controller action. When I’m deep inside the application — like in an action or a service class — a missing model often means there’s an inconsistency in my database state. That’s not the same as a missing resource. Inconsistent database states should generally return a 500 status code, not 404.
In addition, Laravel doesn’t report model not found exceptions to error trackers. This makes sense for 404 responses. But if a model wasn’t found in my core business logic, it means I need to validate earlier or catch the error and deal with it.
I stopped using
findOrFail in actions, aggregate roots, and other core business classes. In those places, I’d rather throw a plain exception that my error tracker will pick up.
