Convert function base view to class based view (DRF) - django

Question

can someone help me convert this function component to class based view (rest framework concrete view)?
I tried converting but landed with errors where serializer is false.
Product image is required in the query.
class Product(models.Model):
title = models.CharField(max_length=200, unique=True)
slug = models.SlugField(max_length=200, unique=True)
description = models.TextField()
price = models.DecimalField(max_digits=10, decimal_places=2, null=True, blank=True)
stock = models.IntegerField()
is_available = models.BooleanField(default=True)
brand = models.ForeignKey(Brand, on_delete=models.CASCADE)
category = models.ForeignKey(Category, on_delete=models.CASCADE)
created_date = models.DateTimeField(auto_now_add=True)
updated_date = models.DateTimeField(auto_now=True)
class ProductImage(models.Model):
image = models.ImageField(upload_to=get_upload_path)
product = models.ForeignKey(Product, on_delete=models.CASCADE, related_name="product_images")
def store(request, category_slug):
cat = None
products = None
if category_slug != None:
cat = get_object_or_404(Category, slug=category_slug)
products = Product.objects.filter(category=cat)
product_count = products.count()
else:
products = Product.objects.filter(is_available=True)
products.count()
context = {
'products': products,
'product_count': product_count
}
return render(request, 'store.html', context)
what i tried with rest framework.
Serializers:
class ProductImageSerializer(serializers.ModelSerializer):
class Meta: model = ProductImage
fields = ('image',)
class ProductSerializer(serializers.ModelSerializer):
product_images = ProductImageSerializer(many=True, read_only=True)
class Meta:
model = Product
fields = "__all__"
def create(self, validated_data):
profile_data = validated_data.pop('product_images')
product = Product.objects.create(**validated_data)
return product
View:
I tried with concrete views, product is filtered by category.
class Store(generics.ListCreateAPIView):
queryset = Product.objects.filter(is_available=True)
serializer_class = ProductSerializer
lookup_field = 'category_slug'
lookup_url_kwarg = 'category_slug'
def list(self, request, *args, **kwargs):
queryset = self.get_queryset()
cat_slug = self.kwargs.get('category_slug')
products = None
if cat_slug is not None:
category = get_object_or_404(Category, slug=cat_slug)
products = queryset.filter(category=category, is_available=True)
else:
products = queryset.filter(is_available=True)
if products.count() == 1:
serializer = ProductSerializer(data=products.first())
elif products.count() > 1:
serializer = ProductSerializer(data=products, many=True)
if not serializer.is_valid():
print(serializer.errors)
data = serializer.data
return Response(data, status=status.HTTP_200_OK)
any help is appreciated.
