I'm not directly modifying any code in a .py file I am simply adding a value to the database table but I am unable to see the change reflected in my drop down lists until I restart the server. Is there a better way of populating choices for my drop down menu? Or could I simply add a cron job that restarts the server periodically(this seems like not a great solution).
