Yes, it sounds like a custom manager will do the job. Here's what I
added:
class CurrentManager(models.Manager):
def get_query_set(self):
return super(CurrentManager,
self).get_query_set().filter(event_date
> datetime.date.today())
class Event(models.Model):
ATTIRE_CHOICES = (
('C', 'Casual'),
('F', 'Formal'),
)
slug = models.SlugField(prepopulate_from=('name',), unique=True,
help_text='This field will prepopulate from the name field.')
name = models.CharField(max_length=200)
location = models.ForeignKey('Location')
description = models.TextField(help_text='Please use <a
href="http://daringfireball.net/projects/markdown/syntax";>Markdown
syntax</a>.')
event_date = models.DateField()
start_time = models.TimeField()
finish_time = models.TimeField()
attire = models.CharField(max_length=1, choices=ATTIRE_CHOICES)
featured_event = models.BooleanField()
featured_event_photo = models.ForeignKey(Photo, blank=True,
raw_id_admin=True, null=True)
category = models.ForeignKey(Category)
objects = models.Manager()
current = CurrentManager()
Only, when I try to get the current Event objects via the Django
shell, I receive an error:
>>> Event.current.all()
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "/home/ypknox/webapps/django/lib/python2.5/django/db/models/
manager.py", line 67, in all
return self.get_query_set()
File "/home/ypknox/webapps/django/ypknox/apps/events/models.py",
line 8, in get_query_set
return super(CurrentManager,
self).get_query_set().filter(event_date > datetime.date.today())
NameError: global name 'event_date' is not defined
It sounds like I'm using "event_date" without defining it first. But
the examples in the Django documentation do the same thing. What am I
doing wrong?
