Django code changes not reflecting on production server
You have to restart your server (WSGI, UWSGI or whatever your use on production environment)
I changed a .py file and changes reflected on local dev. server for Django after deleting .pyc. 
The production server does not even have .pyc for this specific file. Tried touching apache wsgi and restarting apache on prod. server but no luck.
Even deleting this .py file makes application work the same. There is memcached installed but I don't have much idea how it caches, there is .git as well and 5 servers are hosting - one main, 4 load balancers. 
Regards !
