On page 19 of the Django documentation release 1.3.1 It tells you to
add
import datetime
#...
class Poll(models.Model):
def was_published_today(self):
return self.pub_date.date() == datetime.date.today()
I have added this to the models.py code as including the other
__unicode__ additions as:
-----------------------------------------------------------------
start
code------------------------------------------------------------------------
from django.db import models
# Create your models here.
import datetime
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_today(self):
return self.pub_date.date() == datetime.date.today()
class Choice(models.Model):
poll = models.ForeignKey(Poll)
choice = models.CharField(max_length=200)
votes = models.IntegerField()
def __unicode__(self):
return self.choice
-----------------------------------------------------------------
start
code------------------------------------------------------------------------
when I type in the following python commands:
>>> Poll.objects.get(id=3)
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "/usr/local/lib/python2.7/dist-packages/django/db/models/
manager.py", line 132, in get
return self.get_query_set().get(*args, **kwargs)
File "/usr/local/lib/python2.7/dist-packages/django/db/models/
query.py", line 349, in get
% self.model._meta.object_name)
DoesNotExist: Poll matching query does not exist.
>>> Poll.objects.get(pk=1)
<Poll: what's up?>
It all works fine until:
>>> p = Poll.objects.get(pk=1)
>>> p.was_published_today()
Traceback (most recent call last):
File "<console>", line 1, in <module>
AttributeError: 'Poll' object has no attribute 'was_published_today'
I know I'm probably being a thicko (i haven't programmed anything
except a C-64 years ago as a kid), so i'm a n00b!
What am i doing wrong??
Thanks
