ImportError: Settings cannot be imported, because environment variable DJANGO_SETTINGS_MODULE is undefined.
settings.py and manage.py are in the same directory and I did not have this issue before adding this plugin.
the settings.py for database section is as follows:
# Activate django-dbindexer for the default database
DATABASES['native'] = DATABASES['default']
DATABASES['default'] = {'ENGINE': 'dbindexer', 'TARGET': 'native'}
AUTOLOAD_SITECONF = 'indexes'
INSTALLED_APPS = (
# 'django.contrib.admin',
'django.contrib.contenttypes',
'django.contrib.auth',
'django.contrib.sessions',
'djangotoolbox',
'autoload',
'dbindexer',
# social_auth

'social_auth',
#userena
'userena',
'guardian',
'easy_thumbnails',
'accounts',
# djangoappengine should come last, so it can override a few manage.py commands
'djangoappengine',
)
and this is once I runserver

[edited]
I remove the non django project from INSTALL_APP, import the django.models to my accounts/MyProfile, and chmod 777 on the .datastore since it shouldn't ask for permission every time modify it.
{File "/git/ePapyri/epapyri-django/djangoappengine/db/base.py", line 160, in _value_for_db
raise DatabaseError("Only strings and positive integers "
django.db.utils.DatabaseError: Only strings and positive integers may be used as keys on GAE.}

Answer 1

Why are you using django-admin.py to run syncdb and runserver? You should be using manage.py.
And you should definitely not be using sudo to run either of these.
(Also note your INSTALLED_APPS seems to be nonsense: it contains a whole lot of plain Python libraries like httplib2 and oauth2 which have no business at all being there.)
Edited
Firstly, you should have edited your question to add the traceback.
Secondly, the error message is very clear: you have not imported django.db.models in your accounts/models.py file.
Thirdly, it is still nonsense to include non-Django libraries in INSTALLED_APPS. There is simply no need to do so. And your datastore should not have been created with sudo in the first place - either delete and recreate it, or use chmod to make it accessible to a normal user.

Answer 2

I find out the problem is solved by adding a PIL to libraries in GAE, and yaml file would solve the issue, since it was complaining about image library in python. the link to all supported libraries for django is https://developers.google.com/appengine/docs/python/tools/libraries27, so add all the needed libraries to .yaml file and to the INSTALL_APP.
