How can i access QueryString values in Serializer Django Rest Framework

Question

I am trying to access querystring values in serializer class.

class OneZeroSerializer(rest_serializer.ModelSerializer):      location = rest_serializer.SerializerMethodField('get_alternate_name')      def get_alternate_name(self, obj):         view = self.context['view']         print view.kwargs['q']  #output is {}         return 'foo'       class Meta:         model = OneZero          fields = ('id', 'location') 

Views

class OneZeroViewSet(viewsets.ModelViewSet):     serializer_class = OneZeroSerializer     queryset = OneZero.objects.all() 

Is this right way to access querystring?

Answer 1

When using ViewSets, you can access the request in the serializer context (like you access the view). You can access the query params from this

def get_alternate_name(self, obj):     request = self.context['request']     print request.query_params['q']     return 'foo' 

The attribute view.kwargs contains the named arguments parsed from your url-config, so from the path-part.
