django.core.exceptions.ImproperlyConfigured: Error loading cx_Oracle module: libclntsh.so.11.1: cannot open shared object file: No such file or directory
Is this resolvable on Ubuntu?
You need to install both cx_Oracle and an Oracle Client.
cx_Oracle can be found here.
An appropriate Oracle Client can be found here.
You will also need to set the LD_LIBRARY_PATH variable before you start your application. This can usually be done (for example):
export LD_LIBRARY_PATH=/usr/lib/oracle/11.2/client64/lib
Now you should be able to get past the cx_Oracle error message.
First things first - is this actually a Django problem, or just a cx_Oracle problem? Is cx_Oracle installed correctly? Can you connect to your Oracle database in a Python shell session?
import cx_Oracle
conn = cx_Oracle.connect('/') # user/password#dsn
cursor = conn.cursor()
If this doesn't raise an exception, you have connected successfully.
try easy_install cx_Oracle, it will compile cx_Oracle module from source

You shouldn't normally use django-admin, except when you do django-admin startproject.
After you have created the project, it is easier to use manage.py to run the dev server, because it takes care of setting the path and settings module for you.
./manage.py runserver
See the docs for more information.
Maybe you used another python version? It is python 2.7 now, and it seems you don't installed django properly for python2.7. You can try
python3 manage.py runserver
for using python3 in ubuntu (it is installed by default and accessibler with python3), or try to define how to run it with another python version.

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.}
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.
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.
I was using Django with Python 2.7 on Windows 7 and I installed XAMPP and used the PHPMyAdmin MySQL included with it to create a database to use in Django, but when I went and used the "python manage.py syncdb" command, I got this error:

You need to install mysql lib for windows.
http://www.codegood.com/archives/4
http://www.lfd.uci.edu/~gohlke/pythonlibs/#mysql-python
http://www.codegood.com/archives/129
You require a dependency
easy_install mysql-python
I followed the steps here https://developers.google.com/cloud-sql/docs/django and it ran well with django 1.3.1. Now up to Django 1.4 and gives a funny stack trace. I would paste the relevant part of the message here

Error was: cannot import name Thing2Literal
Any help? Some one said it needs to be compiled http://django-irc-logs.com/2012/mar/27/ ?
I had the same issue. Since the problem is with importing Thing2Literal that is used by adapt_datetime_with_timezone_support function from django/db/backends/mysql/base.py and according to this:
https://code.djangoproject.com/changeset/17596/django/trunk/django/db/backends/mysql/base.py this is important only to datetime objects that bypass the model layer and are used with raw sql. So i decided it is not important for me and I messed a bit my django/db/backends/mysql/base.py: comment out code that causes trouble (import of Thing2Literal, adapt_datetime_with_timezone_support function and line 83 where the function is called)
Of course I upload my django 1.4 customized that way to appengine together with my project and it works.
I would appreciate feedback from those who understand django internals better, whether what i've done is ok assuming i don't use raw sql at all.
As you can see in the documentation you've linked, Google App Engine support only Django up to version 1.3 (actually 1.3.1).
