Displaying Resource Names Instead of IDs in Laravel Nova

In Laravel Nova, presenting data clearly and effectively is crucial for a good user experience. One common challenge developers encounter is displaying resource names, such as first and last names, in the ID field instead of the actual ID values. While Laravel Nova does allow this automatically for relationships, it doesn't provide a straightforward way to implement this for all resources out of the box. If you're grappling with this issue, you're in the right place! In this post, we’ll dive into how to solve this problem while retaining the functionality you need.

Understanding the Problem

Imagine you have a model that contains users' first and last names, and you want these names to appear in the ID field on your Nova resource index. You want it to be clickable, taking users to the respective resource details, but when you try to create a new ID field using the first name, it queries the model incorrectly. Here’s what a typical setup may look like:

This doesn’t achieve our goal as it still displays the numerical ID of the resource. Therefore, to meet the requirements, we need a custom approach.

The Solution

Instead of using the ID field in a conventional manner, we can create a new field that combines both the first name and the last name into a clickable link. Here’s how to implement this step-by-step:

Step 1: Create a Custom Text Field

You will need to create a Text field that concatenates the first name and last name while linking to the resource's detail page.

Breaking it Down:

We create a Text field named "Name" and link it to the firstname attribute.

A closure function is used to define the link's URL, combining the resource's URI key and ID.

Finally, we format the name as an HTML link, ensuring it opens the resource detail when clicked.

Step 2: Make the Field Sortable

To sort the records based on the first name field, we need to override the indexQuery function within the resource. Here’s how it looks:

Key Points

The $defaultSort variable is set to 'firstname', which determines the column on which the records will be sorted.

The indexQuery function ensures that the sorting process works as expected based on the defined default sort field.

Conclusion

By implementing a custom text field and overriding the indexQuery function, you can seamlessly display users' names in the ID column while still linking them to the corresponding detail pages. This solution enhances the usability of your Laravel Nova dashboard, allowing for both clarity and functionality. With these steps, you'll create a more intuitive experience for users interacting with your resource listings.

Give this approach a try, and watch how it transforms the way your Nova resources are displayed!
