Graphene-django: AttributeError: 'ForeignKey' object has no attribute 'rel'

[eyalch]

As I was following the docs for Graphene and Django Tutorial using Relay I ran into this error (relevant part):

During handling of the above exception, another exception occurred:

Same here. Is there a fix?

[ericfrederich]

This seems fixed on master: see here

If you just run pip install graphene-django you'll get 2.0.0 which does not have this fix. Use pip pinstall graphene-django==2.1rc1 or whatever the latest is.
