Bad Request when accessing request.data

Question

I want to send data via Ajax to my Django Server. But when I want to read these data I get a bad request error back. I dont know why, other methods like request.method or request.stream work well.

This is the Ajax Call:

jQuery.ajax({
        type: 'post',
        url: 'http://127.0.0.1:8000/termin/get-journey-time/',
        contentType: 'application/json; charset=utf-8',
        data: {
            'method': 'get_journey_time',
            'mandant_id': 1,
            'customer_address': customer_address,
            'staff_group': staff_group_id
        },
        success: function (resultData) {
            console.log(resultData)
        });

This is my view for this post request:

class get_journey_time(generics.ListAPIView):
    """
    Handle Ajax Post to calculate the journey time to customer for the selected staff group
    """
    permission_classes = (AllowAny,)

    def post(self, request, *args, **kwargs):
        body = request.data
        return Response(body)

I get error code 400 Bad Request. Do you know why?

def post(self, request, *args, **kwargs):
        body = request.method
        return Response(body)

or

def post(self, request, *args, **kwargs):
        body = request.stream
        return Response(body)

Work well

Answer 1

You are getting HTTP 400 because your code is raising an exception. Since other methods work, it must be the body = request.data part. After reading the docs I assume there must be something wrong with parsing the data you are POSTing. Like, isn't serializer needed here?

Answer 2

I found my mistake.

After reading the django rest framework documentation I figured out that I have called the wrong parameters in the post method.

def post(self, request, format=None): instead of def post(self, request, *args, **kwargs) worked for me. Thanx all, best!
