Creating an API to Book a Call with an Advisor Using Django REST Framework

In today's fast-paced digital world, many applications require seamless integration of booking systems for appointments or consultations. If you're using Django REST Framework (DRF) and want to create an API endpoint that allows users to book a call with an advisor, you're in the right place. This guide will walk you through the process of creating a robust booking API, highlighting how to extract parameters from the URL while allowing users to submit booking times.

Understanding the Problem

You want to create an endpoint where users can book a call with an advisor, structured like this:

When making a request to the API, you aim to provide the following:

user_id: The ID of the user booking the advisor.

advisor_id: The ID of the advisor being booked.

Booking time: A DateTime string representing when the call should occur.

Initially, you might have structured your API endpoint but found challenges when trying to get the user_id and advisor_id from the URL while only sending the booking time as a request body parameter.

Let's break down how to resolve this issue.

Step-by-Step Solution

1. Modifying the Serializer

To create an API that works as intended, the first step is to adjust your BookingSerializer. We need to set user and advisor fields to be read-only because those values will be set by the URL parameters and should not be directly provided in the request body.

2. Setting Up the View

Now that your serializer is set up to handle the user and advisor IDs appropriately, the next step is to organize your view. You will use the CreateAPIView provided by Django REST Framework since you are creating new booking instances.

3. Updating Your URL Configuration

Make sure your URL configuration captures the user_id and advisor_id as part of the query parameters. Your urls.py should look like this:

4. Testing the Endpoint

With everything put in place, you can now test your API using Postman:

Endpoint: POST /user/<user_id>/advisor/<advisor_id>/

Body (JSON):

Make sure to include appropriate headers for authentication.

Once you send this request, it should create a new booking with the specified advisor for the user while allowing you to specify only the booking time in the request body.

Conclusion

Implementing an API for booking calls with advisors using Django REST Framework can be streamlined by correctly structuring your serializer and views. By extracting necessary parameters from the URL and only passing the booking time as part of the request body, you can build an efficient and user-friendly booking system.
