There is way too much code here. Which part is generating the error? — tadman

It's the home function in the views.py the Rsponse don't accepte multiple dictionaries to return. when I give it only one instance it work fine. but I would like to pass more than one dictionaries. — E.Mohammed

You're passing four separate dictionaries to Response here. You should pass a single one:

return Response(
  {
    'place_list': PlaceSerializer(place_list,many=True).data, 
    'place_order': PlaceSerializer(place_order,many=True).data, 
    'disliked_list': PlaceSerializer(disliked_list,many=True).data,  
    'preferred_list': PlaceSerializer(preferred_list,many=True).data
  }
)

Thank you @Daniel Roseman, It's that the problem. there is no way to pass multiple instances to Response ?

Daniel Roseman Over a year ago

I don't understand your comment. Yes you can pass multiple instances by putting them in a single list or dict.

Thank you return Response({'shop_order': ShopSerializer(shop_order,many=True).data,'disliked_list': ShopSerializer(disliked_list,many=True).data, 'preferred_list': ShopSerializer(preferred_list,many=True).data},)this worked fine, I didn't pay attention to the syntax you gave.

place_list = user.disliked.all()
respose=PlaceSerializer(place_list,many=True)\
return Response(response.data,status=status.HTTP_200_OK)
