Re: get_absolute_url() using related models slugs
Thank you Malcolm and Karen, I had to step for the day but when I got
home I read your comments and fixed the issue which was exactly as you
both pointed out.
this helped make my photo model much more search friendly.
@permalink
def get_absolute_url(self):
return ('photo_detail', None, { 'state' :
self.place.city.state.slug , 'city' : self.place.city.slug, 'place' :
self.place.slug, 'slug': self.slug })
and in my views.py
#photo
url(r'^photo/(?P[-\w]+)/(?P[-\w]+)/(?P[-\w]+)/
(?P[\-\d\w]+)/$',
view = 'photologue.views.photo_detail',
name = 'photo_detail',
),

As Malcolm said, within get_absolute_url, self is already the Photo
instance, so it is confusing what you are trying to get at when you use
'self.photo' here. In fact given the models you have defined, self.photo is
referencing the model manager for the set of Gallery instances that have
self as 'featured_photo'. (I think you might want to rethink that
related_name specification, since it seems to be confusing enough to have
tripped you up here.)
Within get_absolute_url, to refer to the photo instance, just use self, not
self.photo. When you fix that you are going to hit an error because the
Place model does not have a slug field, and yet you are trying to access it
when you code self.place.slug. I don't know what you are really intending
to specify here.

Re: get_absolute_url() using related models slugs
Thank you, I updated get_absolute_url to take into consideration the
fact that I was erroneously using state_slug instead of state.slug and
the same with photo.slug and place.slug
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 })
>>> from photologue.models import *
>>> photo = Photo.objects.get(slug='golf-course-3')
>>> photo.get_absolute_url()
still getting this error:
AttributeError: 'RelatedManager' object has no attribute 'place'

I have no idea what "self.photo" is referring to there, since "self" is
the Photo instance and it doesn't have a "photo" attribute. I'm pretty
tired at the moment, so maybe I'm missing something, or maybe you didn't
post your actual code. In any case, it looks like the "self.photo" bit
is just wrong, so I'd start by fixing that.

would give a bigger picture.

You're accessing a non-existent attribute on the City model. Maybe you mean to state.slug instead of state_slug or maybe you mean something else there. In any case, there is no state_slug attribute.

get_absolute_url() using related models slugs
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.'))
@permalink
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 "", line 1, in ?

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.
