Always get None from Django api request as result

Question

I am going to get whitebg_url result from sqlite database according to matched items and made the api request using django like this.

@api_view(['POST'])
def getUrlFromAttributes(request):

    try: 
        print('>>>>>>>>>>>>>>>>>>>>>', request)
        hairstyle = request.data.get("hairstyle")
        haircolor = request.data.get("haircolor")
        skincolor = request.data.get("skincolor")
        print("error>>1", str(hairstyle), str(haircolor), str(skincolor))

        basic_query = BasicSetup.objects.all().filter(skin_color=skincolor, hair_color=haircolor, hair_style=hairstyle, isDeleted= 0)
        print('returned basic query : ', basic_query)
        lists_basicSetup = list(basic_query.values( 'whitebg_url'))
        print('returned lists_basicSetup : ', lists_basicSetup)
        return JsonResponse({'result': lists_basicSetup})       
    except Exception as error:
        print("error", str(error))       
        return JsonResponse({'result': str(error)})

But as you can see the result at the below image, response is always None. I tried to find the solution from google, but can't do it.

I already add rest_framework at INSTALLED_APPS in settings.py file.

and path is like defined. path('getUrlFromAttributes', views.getUrlFromAttributes, name='getUrlFromAttributes'),

I tried to do this using Postman, but the result was same.

Anyone knows why I was getting None as result?

Answer 1

The GET parameters are not stored in request.data. Check request.GET. See documentation

Answer 2

Take a look at the (your) image above. Do you notice the Hairstyle, haircolor skincolor, etc parameters in the url?

That happens with a GET request. Yes, the log shows POST, meaning a POST event did happen.

There's all likeness that your data aren't actually POSTed, that's why you don't get them in the view function.

Suggestions:

1. Cross check your JS file responsible for the POSTing (you can share here if you want).
2. Try grabbing the parameters off the url instead (GET method, if non-sensitive information) if Your POSTing isn't working, just to test my theory.

request.query_params
