RuntimeWarning: DateTimeField received a naive datetime
I m trying to send a simple mail using IPython. I have not set up any models still getting this error. What can be done?
Error : /home/sourabh/Django/learn/local/lib/python2.7/site-packages/django/db/models/fields/ init .py:827: RuntimeWarning: DateTimeField received a naive datetime (2013-09-04 14:14:13.698105) while time zone support is active. RuntimeWarning)
Tried : The first step is to add USE_TZ = True to your settings file and install pytz (if possible).
Error changed:
(learn)sourabh@sL:~/Django/learn/event$ python manage.py shell
/home/sourabh/Django/learn/local/lib/python2.7/site-packages/django/db/backends/sqlite3/base.py:53: RuntimeWarning: SQLite received a naive datetime (2013-09-05 00:59:32.181872) while time zone support is active.
RuntimeWarning)
The problem is not in Django settings, but in the date passed to the model. Here's how a timezone-aware object looks like:
>>> from django.utils import timezone
>>> import pytz
>>> timezone.now()
datetime.datetime(2013, 11, 20, 20, 8, 7, 127325, tzinfo=pytz.UTC)
And here's a naive object:
>>> from datetime import datetime
>>> datetime.now()
datetime.datetime(2013, 11, 20, 20, 9, 26, 423063)
So if you are passing email date anywhere (and it eventually gets to some model), just use Django's now() . If not, then it's probably an issue with an existing package that fetches date without timezone and you can patch the package, ignore the warning or set USE_TZ to False.

使用django.utils.timezone.make_aware函数使您的天真日期时间对象能够识别时区，并避免出现这些警告。
