I am using Django raw function to run a SQL statement on Postgres to get a
count on the database in the view function but I could not figure out how
to setup the serializer for it. Any help will be appreciated it. Below is
my code for view and the serializer.
View:
@api_view()def count_person_time_series(request,person):
try:
serializer = RSerializer(RModel.
objects.raw( "SELECT date,count(*) from
rtable where %s =ANY(person) group by date",[person]), many=True)
except RModel.DoesNotExist:
raise Http404("person does not exist")
return Response(serializer.data)
Serilizer:
class RSerializer(serializers.ModelSerializer):
## I could not figure out this part
person_count = serializers.SerializerMethodField()
class Meta:
model = RModel
fields = '__all__'
