list to object

[Anuj Techsmart]

Dear All,
I am working on rest framework api and trying to get data from two models. like this

class UserAllNFTS(viewsets.ModelViewSet):

"""

Fetchig all nfts for home page data

"""

if(UserNFTDetails.objects.filter(nft_product_status=0).exists()):

nft_image = ''

minted_nfts = []

userData = UserNFTDetails.objects.filter(nft_product_status=0)

for nftdata in userData:

#### fetching product images

userTotalInfo = UserNFTInfo.objects.get(product_id = nftdata.product_id)

product_image = userTotalInfo.product_image

#### fetching creator image & creator name

creatordata = UserRegister.objects.get(id = nftdata.user_id)

creator_name = creatordata.user_full_name

creator_image = creatordata.userimage

#### fetching total likes of products

if ProductTotalLikes.objects.filter(product_id = nftdata.product_id).exists():

pro_data = ProductTotalLikes.objects.get(product_id = nftdata.product_id)

product_total_likes = str(pro_data.total_likes)

else:

product_total_likes = 0

minted_nfts.append(

{

"nft_productID":nftdata.product_id,

"nft_title":nftdata.nft_title,

"nft_descriptions":nftdata.nft_descriptions,

"nft_collection":nftdata.nft_collection,

"nft_price":nftdata.nft_price,

"nft_royalties":nftdata.nft_royalties,

"nft_image":product_image,

"symbol": userTotalInfo.symbol,

"creator_name":creator_name,

"profile_image":'uploads/'+str(creator_image),

"total_likes":product_total_likes

}

)

serializer_class = UserSerializer

and i got error 
 assert queryset is not None, '`basename` argument not specified, and could ' \
AssertionError: `basename` argument not specified, and could not automatically determine the name from the viewset, as it does not have a `.queryset` attribute.

Please help me.
