How can modify request.data in django REST framework

Question

I am using Django REST Framework

request.data = '{"id": "10", "user": "tom"}' 

I want to add extra attribute like "age": "30" before sending it to further like

    request.data = new_data     response = super().post(request, *args, **kwargs) 

I have two issues

1. Why request.data is coming as string rather than dict
2. How can i update the request.data

Answer 1

In case your API is APIView then you should use update function to expand your request data object without losing the data sent from the client-side.

request.data.update({"id": "10", "user": "tom"}) 

Answer 2

request.data should be an immutable QueryDict, rather than a string. If you need to modify it:

if isinstance(request.data, QueryDict): # optional     request.data._mutable = True request.data['age'] = "30" 

The only reason you might check if it's an instance of QueryDict is so it's easier to unit test with a regular dict.
