how to implement multiple request values for single field in django

Question

With this curl command I am requesting for only "Books" for field "ProductName"

curl -X POST http://localhost:8000/Productfilter/ -d '{"ProductName":"Books"}' -H "Content-Type:application/json"

Api code:

 def Productfilter(self, request, format=None)
   queryset = Model.objects.filter(ProductName=request['ProductName'])
   ser = ModelSerializer(queryset, many=True)
      for item in ser.data:
         sendData.append({"ProductUrl": item['ProductUrl']}]   
   return sendData

I want to implement for multiple request values for same field. Like I want something like this--->

curl -X POST http://localhost:8000/Productfilter/ -d '{"ProductName":"Books","Pencil","Copy"}' -H "Content-Type:application/json"

Please suggest the curl command for this type of requests and what modification to be done in coding of def Productfilter .

views.py

class Productfilter(APIView):
    def post(self, request, format=None):

        request.data['PubIp'] = getUserIP(request)
        returnData = ApiFiltReq.Productfilter(self, request.data, format=None)
        if returnData == "RECORD_NOT_FOUND":  # bad request
            return Response(ErrorCodes.ERROR_CODE_LIST[returnData], status=status.HTTP_400_BAD_REQUEST)
        elif returnData == "DJANGO_ENTRY_FAILED":
            return Response(ErrorCodes.ERROR_CODE_LIST[returnData], status=status.HTTP_400_BAD_REQUEST)
        else:
            return Response(returnData, status=status.HTTP_202_ACCEPTED)

Answer 1

First thing, if you're only asking for data you should use a GET request.

Second thing, I assume that this ProductName=request['ProductName'] is a typo and you're really using request.POST[xxx] (which should be request.GET[xxx] actually cf first point above)

wrt/ how you can get multiple values for the same key on the Django side, you just have to use request.GET.getlist(xxx) and change your query to Model.objects.filter(ProductName__in=yyy) :

def Productfilter(self, request, format=None)
    names = request.GET.getlist('ProductName')
    queryset = Model.objects.filter(ProductName__in=names)
    # etc

for the cURL part you'll have to check the FineManual but IIRC this should work:

curl -G http://localhost:8000/Productfilter/ --d ProductName=Books -d ProductName=Pencil -d ProductName=Copy

or just pass a plain querystring in your url:

curl -G http://localhost:8000/Productfilter/?ProductName=Books&ProductName=Pencil&ProductName=Copy

Answer 2

Try this:

def Productfilter(self, request, format=None)
   queryset = Model.objects.filter(ProductName=request.data['ProductName'], Pencil=request.data['Pencil'])
   ser = ModelSerializer(queryset, many=True)
      for item in ser.data:
         sendData.append({"ProductUrl": item['ProductUrl']}]   
   return sendData 

and the curl command will look like this:

curl -X POST \
http://localhost:8000/Productfilter/ \
-d ProductName=Books
-d Pencil=Copy
-H "Content-Type:application/json"

Hope it helps!
