Displaying Laravel Nova Resources Multiple Times with Different Conditions

Laravel Nova is a powerful administration panel used to manage your application's resources with ease. However, one common question developers often have is: is it possible to display a Laravel Nova resource multiple times under different conditions? This guide will walk you through how to achieve that in an efficient way. Specifically, we will address a scenario involving notifications and messages, similar to what many developers face in real-world applications.

The Problem

Consider you have a Notification resource in your Laravel application. You want to manage this resource in two different ways:

Display all notifications, excluding those that are of type \App\Message.

Create a separate view for Messages that only shows notifications where the type is equal to \App\Message.

You may be wondering if it’s feasible to display the same resource under these different conditions in Laravel Nova, and the answer is: Yes, it is possible!

The Solution

To solve this problem, you can create two different resources that reference the same underlying model (for instance, the Notification model) and apply different conditions to each resource. Here’s how you can do it step by step.

Step 1: Create a New Resource

First, you need to create a new resource. This resource will be the one that displays only the messages. You can do this easily with the Artisan command:

Step 2: Define the Index Query

In your new resource file (e.g., MessageNotification.php), you should specify the condition that will filter the resources. You do this by overriding the indexQuery method. Here’s an example:

Step 3: Modify the Existing Resource

Next, you will want to modify your existing Notification resource to exclude messages. Open the existing resource file (e.g., Notification.php) and again override the indexQuery method:

Step 4: Register Both Resources

Now that you have created two separate resources with the necessary conditions, make sure to register them in your Nova service provider. You can do this by specifying both in the resources method:

Conclusion

By following the above steps, you can successfully display a Laravel Nova resource multiple times with different conditions. This approach provides flexibility in managing resources that share the same model yet serve different purposes depending on the context of the application.

Now you can easily manage notifications and messages through their respective Nova interfaces, ensuring a smoother experience for both developers and users alike.
