Hey, I had the same error though not necessarily the same situation:
We were working with old Django 1.7, and had some HStores and used
django_hstore lib since Django didn't natively support HStore back then.
anyways, when migrating to 1.11 just now, I dropped the usage of
django_hstore and used the native HStoreField. however, I imported it wrong
in the model, and instead of:
from django.contrib.postgres.fields import HStoreField
I used:
from django.contrib.postgres.fields import hstore
and instead of:
process_status = HStoreField(default={}, blank=True)
I used:
process_status = hstore.HStoreField(default={}, blank=True)
it was working, but in DRF it failed with this error.
also, and maybe that was the real thing, I forgot to add
'django.contrib.postgres',
to my INSTALLED_APPS.
hope this helps someone as clumsy as me :)
