Last active May 6, 2016 03:55
Closes the db connection when it's gone because of a long period of inactivity (solves this issue https://code.djangoproject.com/ticket/21597). It forces django to use a new fresh connection.
from django.db import connection
from functools import wraps
def check_db_connection(f):
@wraps(f)
def inner(*args, **kargs):
try:
connection.connection.ping()
except:
connection.close()
return f(*args, **kargs)
