Hi,

Please, paste your code in the mail instead of screenshots, it makes it hard to read.

In your view, you are passing an Article instance to your serializer along with the many=True keyword which means the serializer will expect an iterable of Articles as the error suggests.

The question is, what are you trying to do and what outcome are you expecting ?

https://www.django-rest-framework.org/api-guide/serializers/#dealing-with-multiple-objects

You specify many=True in the serializer constructor; hence the serializer expects a list of objects. You provide a single object; hence you get an error about argument not being iterable.
