Serializer handing Foreign Key in Django REST Framework
In this video, we explore how to create a product using Django REST Framework while associating it with a user by their username instead of the user ID. You'll learn how to modify your ProductSerializer to accept a username as input for the user field and convert it into a User instance during the product creation process.
We'll walk you through the updated serializer, including how to validate the username and fetch the corresponding User object from the database. By the end of the video, you'll be able to send a POST request from Postman with the username and successfully create a product linked to the user. Don't forget to check the code and debugging tips to ensure everything works seamlessly.
