[Answer]-Openshift doesn't perform syncdb on push

From the cartridge docs:

For backward compatibility, the wsgi/application path is selected as default WSGI entry-point > with higher priority. You can customize the path using the OPENSHIFT_PYTHON_WSGI_APPLICATION > environment variable.

But it looks like your application is in the right path so, I would check your action_hooks in the repo under ~/.openshift/action_hooks/ to see if there are some custom actions defined.
