django-slug-preview 2.0.1

Special model URLS

When a model has a custom URL layout (not just /{slug}/), you can add a get_absolute_url_format() method in the model. For example:

from django.db import models
from slug_preview.models import SlugPreviewField

class Page(models.Model):
    parent = models.ForeignKey('self')
    slug = SlugPreviewField(_("Slug"))
    # ...


    def get_absolute_url(self):
        if self.parent_id:
            return "{0}{1}/".format(self.parent.get_absolute_url(), self.slug)
        else:
            return "/{0}/".format(self.slug)

    def get_absolute_url_format(self):
        if self.parent_id:
            return "{0}{{slug}}/".format(self.parent.get_absolute_url())
        else:
            return "/{slug}/"

For a blog, you can add the /blog/{year}/{month}/ format too:

from django.core.urlresolvers import reverse
from django.db import models
from django.utils.timezone import now
from slug_preview.models import SlugPreviewField

class Article(models.Model):
    slug = SlugPreviewField(_("Slug"))
    pubdate = models.DateTimeField(default=now)
    # ...

    def get_absolute_url(self):
        root = reverse('article_list')
        return "{root}/{year}/{month}/{slug}/".format(
            root=reverse('article_list').rstrip('/'),
            year=self.pubdate.strftime('%Y'),
            monthy=self.pubdate.strftime('%M'),
            slug=self.slug
        )

    def get_absolute_url_format(self):
        root = reverse('article_list')
        pubdate = self.pubdate or now()
        return "{root}/{year}/{month}/{{slug}}/".format(
            root=reverse('article_list').rstrip('/'),
            year=pubdate.strftime('%Y'),
            monthy=pubdate.strftime('%M'),
        )
