Why delete option not coming in the http://127.0.0.1:8000/store/products when we override Destroy method.

Please assist ASAP. I am using the same code which Mosh is using in Django., I am in Routers Video of Django_Part 2.

Remove the delete method completely and for destroy method write the following code:

    def destroy(self, request, *args, **kwargs):
        if OrderItem.objects.filter(product_id=kwargs['pk']).count() > 0:
            return Response({'error': 'Product cannot be deleted as it is associated with an order item.'},
                            status=status.HTTP_405_METHOD_NOT_ALLOWED)
        return super().destroy(request, *args, **kwargs)

This may help

So, my query here is why implementing the def destroy method removes the Delete

button from he product list in the below code:

class ProductViewSet(ModelViewSet):

queryset = Product.objects.select_related('collection').all()

serializer_class = ProductSerializer

filter_backends = [DjangoFilterBackend]

filterset_fields = ['collection_id']



def get_serializer_context(self):

    return {'request':self.request}



def destroy(self, request,*args , **kwargs):

    if OrderItem.object.filter(product_id=kwargs['pk']).count() > 0:

        return Response({'error': 'Product cannot be deleted because it is associated with an order item.'}, status=status.HTTP_405_METHOD_NOT_ALLOWED)

    return super().destroy(request,*args,**kwargs)

while, keeping the “def delete” method retain the Delete button from product-list.

def delete(self,request,pk):

    product = get_object_or_404(Product, pk=pk)

    if product.orderitems.count() > 0:

        return Response({'error': 'Product cannot be deleted because it is associated with an order item.'}, status=status.HTTP_405_METHOD_NOT_ALLOWED)

    product.delete()

    return Response(status=status.HTTP_204_NO_CONTENT)

Why having the “def destroy” enables the Delete button in only Product list not in Product Detail, this is my query. please assist
