How to get total number

Question

How to get the total number of loved clicked? My attempt is below, but it is not working.

This is my model:

class Review(models.Model):
    reviewer    = models.ForeignKey(User, related_name='review', on_delete=models.CASCADE)
    product     = models.ForeignKey(Product, related_name='review', on_delete=models.CASCADE, null=True)
    date_time   = models.DateTimeField(auto_now_add=True)
    comment     = models.TextField(max_length=250, blank=True, null=True)
    rating      = models.CharField(choices=RATING_CHOICES, max_length=150)
    loved       = models.BooleanField(default=False)

This is my view:

class ListReviewAPIView(generics.ListAPIView):
      queryset = Review.objects.filter(loved="True").count()
      serializer_class = ReviewSerializers

The serializers

class ReviewSerializers(serializers.ModelSerializer):
class Meta:
    model = Review
    fields = ['product', 'comment', 'rating', 'loved', 'date_time', 'reviewer']

Answer 1

Can't you just override get method to simplify what you want to do?

class GetReviewRate(APIView):
    def get(self, request, *args, **kwargs):
        count = Review.objects.filter(loved=True).count()
        return Response({'loved_count': count})

Also Boolean values are False/True , not "False"/"True" , they're not strings. Remember about that.
