I am still learning Django, and appreciate all of the help I have
received. I spent a few hours on this and just cannot figure out how
to pull off the get_absolute_url() function the way I describe it
below for the Photo class. I want to use the slugs for related models
and step through multiple relations. I can get to the id's of the
related models as shown in the shell transcript below, but not the
slugs yet.
extracted from models.py
====================
class State(models.Model):
state = models.CharField(max_length=100, unique=True)
slug = models.SlugField(prepopulate_from=('state',))
class City(models.Model):
state = models.ForeignKey(State)
featured_place = models.ForeignKey('Place', related_name='place',
null=True, blank=True)
city = models.CharField(max_length=100, unique=True)
slug = models.SlugField(prepopulate_from=('city',))
class Place(models.Model):
city = models.ForeignKey(City)
featured_gallery = models.ForeignKey('Gallery',
related_name='gallery', null=True, blank=True)
class Gallery(models.Model):
user = models.ForeignKey(User)
place = models.ForeignKey(Place)
featured_photo = models.ForeignKey('Photo', related_name='photo',
null=True, blank=True)
pub_date = models.DateTimeField(_('date published'),
default=datetime.now)
title = models.CharField(_('title'), max_length=100, unique=True)
slug = models.SlugField(_('slug'), prepopulate_from=('title',),
unique=True,
help_text=_('A "Slug" is a unique URL-
friendly title for an object.'))
is_public = models.BooleanField(_('is public'), default=True,
help_text=_('Public galleries will
be displayed in the default views.'))
photos = models.ManyToManyField('Photo', related_name='galleries',
verbose_name=_('photos'), filter_interface=models.HORIZONTAL)
class Photo(models.Model):
user = models.ForeignKey(User)
place = models.ForeignKey(Place)
image = models.ImageField(_('photograph'), upload_to=PHOTOLOGUE_DIR
+"/photos/%Y/%b/%d")
pub_date = models.DateTimeField(_('date published'),
default=datetime.now)
title = models.CharField(_('title'), max_length=100, unique=True)
slug = models.SlugField(_('slug'), prepopulate_from=('title',),
unique=True,
help_text=('A "Slug" is a unique URL-
friendly title for an object.'))

def get_absolute_url(self):
return ('photo-detail', None, { 'state' :
self.photo.place.city.state_slug , 'city' :
self.photo.place.city_slug, 'place' : self.photo.place_slug, 'slug':
self.slug })
***Shell output
>>> from photologue.models import *
>>> photo = Photo.objects.get(slug='golf-course-3')
>>> photo.place.city.state_slug
Traceback (most recent call last):
File "<console>", line 1, in ?
AttributeError: 'City' object has no attribute 'state_slug'
>>> photo.place.city.state_id

>>> photo.get_absolute_url()
return ('photo-detail', None, { 'state' :
self.photo.place.city.state_slug , 'city' :
self.photo.place.city_slug, 'place' : self.photo.place_slug, 'slug':
self.slug })
AttributeError: 'RelatedManager' object has no attribute 'place'
Any hints would be appreciated.
