[Answered ]-Django + uwsgi, where to place my startup code?

Put your startup code in a separate file, for example startup.py and then alter these two files:

manage.py

# some code
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "[project name].settings")
if __name__ == "__main__":
    import startup
    # the rest of the code

[project name]/wsgi.py

# some code
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "[project name].settings")
import startup
# the rest of the code

Note the order: import is always after environ setting (might not be important, depends on what startup does).

In Django1.7 you can use ready function per application. Read this:
