Django Rest Framework: How GET Requests Retrieve and Serialize Data into JSON
In this video, I'll walk through the process of how Django Rest Framework (DRF) handles GET requests and how it retrieves data from the database. When a GET request is made, we fetch the data using Django's ORM with Category.objects.all(), which returns a QuerySet containing all the records from the Category table.
This QuerySet is then passed to the CategorySerializer, which converts it into a Python dictionary. Once serialized, the data is automatically converted into JSON format by DRF before it's sent back as a response to the client, such as Postman or any frontend application.
This process is what allows your application to interact with the database, convert data to a usable format, and return it as JSON for easy consumption. Stay tuned as we explore this workflow in more detail!
