I'm a Django newbie,
I am following a tutorial and I had to create two models shown below:
import datetime
from django.db import models
from django.utils import timezone
class Poll(models.Model):
question = models.CharField(max_length=200)
pub_date = models.DateTimeField('date published')
def __unicode__(self):
return self.question
def was_published_recently(self):
return self.pub_date >= timezone.now() - datetime.timedelta(days=1)
class Choice(models.Model):
poll = models.ForeignKey(Poll)
choice_text = models.CharField(max_length=200)
votes = models.IntegerField()
def __unicode__(self):
return self.choice_text
The following code is from the tutorial. I should get True.
# Make sure our custom method worked.
>>> p = Poll.objects.get(pk=1)
>>> p.was_published_recently()
True
But when I type (same lines as tutorial):
>>> p = Poll.objects.get(pk=1)
>>> p.was_published_recently()
I get the following error message:
models.py line 12 in was_published_recently
NameError: global name 'datetime' is not defined..
I imported datetime
and timezone
... I don't see why I get that error message.
Couldn't reproduce the problem, your code works for me. You could try with something like this:
from datetime import timedelta as tdelta
...
def was_published_recently(self):
return self.pub_date >= timezone.now() - tdelta(days=-1)
