what actually it is doing (data=request.data)?

def post(self,request):
        serializer=NameSerializers(data=request.data)
        if(serializer.is_valid):
            name=serializer.data.get('name')

            msg='hello {} Wish you happy New Year'.format(name)
            return Response({'msg':msg})
        return Response(serializer.errors,status=400)

My questions are:

  1. Is data=request.data getting the data the client app has been sending in JSON?
  2. Is serializer.is_valid an in-built function of serializer class to check the data we have received is valid data or not?
  3. What is serializer.data.get('name') doing?

  1. request.data is basically data sent in the request body from the client.
  2. serializer.is_valid(), yes, it is a function to check data received from the request, you can pass serializer.is_valid(raise_exception=True) to raise an exception in case of invalid data received.
  3. serializer.data is a python dictionary which is being saved in the model, so .get('var_name') is actually accessing the value from the dictionary.

Hope this helps :) Happy Coding
