Thank you very much for quick response. I just found what's the real
problem: in
./env/nodeshot/lib/python2.7/site-packages/django_hstore/query.py
actually HStoreGeoQuerySet definition is under condition:
if GEODJANGO_INSTALLED:
which is defined in
./env/nodeshot/lib/python2.7/site-packages/django_hstore/apps.py that
check if there's a "postgis" in database ENGINE setup of settings.py. So
in case there's no "postgis" pattern in ENGINE string, HStoreGeoQuerySet
is just got missed and it"s not a circular import problem.
Then after I changed ENGINE from
'django.db.backends.postgresql_psycopg2' to
'django.contrib.gis.db.backends.postgis', everything worked perfectly
and my nodeshot site is now up in AWS.
Best regards,
Hui Yu
