Updating User and Profile Models through One View in Django

In the world of web development, especially when working with Django and Django Rest Framework, crafting a smooth user experience often involves efficiently handling data updates. If you’re working with multiple related models, such as User and Profile, the question arises: How do you update these models seamlessly with a single request? In this post, we’ll explore this challenge and provide a clear solution.

The Challenge

You have two models, User and Profile. The Profile model is connected to the User model through a one-to-one relationship. Your goal is to update both user details and profile settings simultaneously through a single PUT request. Here’s the model structure to keep in mind:

And User is built on Django’s AbstractUser. When you send an update request, the expected payload looks like this:

With this scenario, the challenge lies in processing both models with one request, ensuring the user details and profile are updated accordingly. Let’s dive into the solution.

The Solution: Overriding the Serializer Update Method

To accomplish this, we can override the update method in the serializer. This allows us to manipulate the incoming data before saving it into the database. Here's how to implement this in your Django application:

Step 1: Create a Custom User Serializer

Start by creating a serializer for your User model. This is where we’ll handle the logic of updating both the User and Profile models:

Step 2: Explanation of the Code

Data Extraction: We begin by using the pop method to remove the profile-related fields from validated_data. This is crucial as we need to handle these separately.

Profile Update Logic: Next, we check if based_location or is_available are provided. If they are, we update the respective fields in the Profile and save these changes.

Final User Update: After updating the profile, we call the superclass's update method to ensure any remaining data for the User model is saved correctly.

Conclusion

By overriding the update method in your serializer, you can manage complex updates involving multiple models seamlessly. This approach ensures that your application remains efficient and your data stays consistent. With this method, you not only simplify your API usage but also enhance the overall user experience.

Now you’re equipped with the knowledge to update the User and Profile models with a single PUT request in Django. Next time you encounter a similar challenge, you’ll know exactly how to tackle it!
