How does the rest framework work in Django?
Django Rest Framework. DRF takes care of the heavy lifting of transforming our database models into a RESTful API. There are two main steps to this process: first a serializer is used to transform the data into JSON so it can be sent over the internet, then a View is used to define what data is sent.

Can you build a blog app with Django?
In this tutorial we will build the API for a blog app featuring CRUD (Create-Read-Update-Delete) functionality with Django Rest Framework.

— Django documentation. REST framework supports HTTP content negotiation by providing a Response class which allows you to return content that can be rendered into multiple content types, depending on the client request. The Response class subclasses Django’s SimpleTemplateResponse.
Which is a response object in the rest framework?
REST framework also introduces a Response object, which is a type of TemplateResponse that takes unrendered content and uses content negotiation to determine the correct content type to return to the client. return Response(data) # Renders to content type as requested by the client.
How does the response class work in Django?
The Response class subclasses Django’s SimpleTemplateResponse. Response objects are initialised with data, which should consist of native Python primitives. REST framework then uses standard HTTP content negotiation to determine how it should render the final response content.
When is an exception raised in Django rest?
Raised when an incoming request occurs that does not map to a handler method on the view. By default this exception results in a response with the HTTP status code “405 Method Not Allowed”. Raised when an incoming request occurs with an Accept header that cannot be satisfied by any of the available renderers.
