Example in reference of Database Functions leads to NameError

[Michael Käufl]

The following example (just above ​https://docs.djangoproject.com/en/1.11/ref/models/database-functions/#trunc) leads to a NameError, because melb is not defined.

>>> import pytz
>>> tzinfo = pytz.timezone('Australia/Melbourne')
>>> Experiment.objects.annotate(
...     day=ExtractDay('start_datetime', tzinfo=melb),
...     weekday=ExtractWeekDay('start_datetime', tzinfo=melb),
...     hour=ExtractHour('start_datetime', tzinfo=melb),
... ).values('day', 'weekday', 'hour').get(
...     end_datetime__year=ExtractYear('start_datetime'),
... )
