Creating object with generics CreateApiView 'request' required - django

Question

This is my serializer and Viewset, i want to create an instance of Like if someone likes a product (Post request 'products/product:id/like'). But i get an error that 'request' is required.
class LikeSerializer(serializers.ModelSerializer):
user = serializers.PrimaryKeyRelatedField(read_only=True, default=serializers.CurrentUserDefault())
product = serializers.PrimaryKeyRelatedField(read_only=True)
class Meta:
model = Like
fields = ('user', 'product',)
class LikeProductApi(generics.CreateAPIView):
queryset = Like.objects.all()
serializer_class = LikeSerializer
def create(self, request, *args, **kwargs):
product_id = self.kwargs['pk']
product = ProductInStore.objects.get(id=int(product_id))
if Like.objects.filter(user=self.request.user, product=product).exists():
raise ValidationError(_("This user already likes this product"))
else:
return super().create(user=self.request.user, product_id=product_id, **kwargs)

Do you have any idea why?

Answer 1

You are making a super() call with the wrong parameters, it should be:
def create(self, request, *args, **kwargs):
product_id = self.kwargs['pk']
if Like.objects.filter(user=self.request.user, product_id=product_id).exists():
raise ValidationError(_("This user already likes this product"))
else:
return super().create(request, *args, **kwargs)

Answer 2

The issue is how you're calling create()
Try the below:
In the PythonKuba/api/ecommerce/views.py file
return super().create(request=self.request, product_id=product_id, **kwargs)
At the moment you are sending in the user, not the request
