Introduction

If you’re working with Django Rest Framework (DRF) to develop APIs, you may encounter a situation where you need to modify your JSON response structure. Specifically, you might find yourself wanting to convert a standard array of JSON objects into a more structured key/attribute JSON object.

This type of transformation is useful because it allows clients to access data in a more intuitive way by using unique identifiers as keys. Let's delve into how you can achieve this transformation in your Django Rest Framework application.

The Problem

Imagine you receive a JSON array from your backend that looks like this:

Is It Possible?

Yes, you can easily configure your Django Rest Framework application to return data in this desired format. Below are the methods to accomplish this.

Solution

1. Modify Data Before Sending It

If your use case allows you to modify your data right before sending it as a response, you can achieve the desired format with the following code:

2. Using a Serializer

If you are utilizing serializers in your Django app, the process is slightly different but still straightforward. You can use the to_representation method to transform the data while it is being serialized. This approach has no performance drawbacks compared to the default representation.

Here is how you could implement it:

Conclusion

By following the above methods, you can easily transform your JSON responses in Django Rest Framework to a key/attribute format. This allows clients to access data in a more user-friendly manner, directly referencing records by their unique identifiers. Whether you choose to manipulate the data before sending it or leverage serializers to format it during serialization, these techniques can enhance the usability of your API.

Now that you know how to return a structured JSON object in Django Rest Framework, feel free to implement it in your projects to streamline data access for your clients!
