I wrote this a long time ago. Maybe it's what you need:
*from *django.conf *import *settings
*from *django.contrib.sites.models *import *Site
*from *django.core.urlresolvers *import *reverse
*from *django.db *import *models
*class PublicModel(*models.Model*): *"""A model that has a place on the site.
Specifically, this adds the following method to the model: -
get_absolute_url(): the
url from the base of the site to the detail view of the model. It is
implemented as
the get_absolute_url() method so that the Django admin will provide a
"View on
site" link. The default implementation returns the url associated with:
appname.views.modelname and is decorated with the permalink decorator.
Additionally the following property is added (implemented as a getter and
setter): -
fully_qualified_url: A url that specifies the server and protocol as well
as the
absolute url. It is intended to be used for: - out of band communications
like email;
- setting or changing the protocol security; - changing or setting the
associated
site; The general purpose of the model is to make it easier to get this
information
in a template and handle it in a view. """ _site_id *= None *_protocol
*= None
@models.permalink def get_absolute_url(*self*): *model_name *=
*self._meta.object_name.lower*() *viewname *=
'{}_detail'*.format*(*model_name*) return *viewname, [*/str/(*self.pk*)*]
absolute_url *= /property/(*get_absolute_url, doc*="Absolute url")
def get_fully_qualified_url(*self*): *site_id *= *self._site_id *or
