Get current site inside model
Max
Vijay Khemlani
otherwise it doesn't make sense
For example, when calling the method from the shell (not a web
request) what will you expect it to return?

{{obj.get_url}} <- error Site does not exists [set site_id or use 1)]
return 'http://{}{}'.format(Site.objects.get_current(????).domain,
reverse(viewname='product',
args=[self.slug]))

available inside the method, then what do you expect it to return? I'm
not asking programatically, but logically,
If you only care about the template the you can concatenate the domain
and the absolute path in the template itself
{{ domain }}{{ ob.get_absolute url }}
where the absolute url is something like '/model/5' or something like
that, without the domain.

Once again, if you don't have a default site_id or the request object
available inside the method, then what do you expect it to return? I'm
not asking programatically, but logically,

You could generate the urls on the view and pass them already
generated to the template

I thought about it.

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 getattr(settings, 'SITE_ID', 1)
protocol = self._protocol or 'http'
try:
site = Site.objects.get(pk=site_id)
except Site.DoesNotExist:
raise ImproperlyConfigured(
'Site with id {} does not exist'.format(site_id))
url = '{}://{}{}'.format(protocol, site.domain, self.absolute_url)
return url
def set_fully_qualified_url(self, protocol, site_id_or_obj=None):
if site_id_or_obj is None:
site_id = self._site_id or getattr(settings, 'SITE_ID', 1)
site = Site.objects.get(pk=site_id)
elif isinstance(site_id_or_obj, Site):
site = site_id_or_obj
else:
site = Site.objects.get(pk=site_id_or_obj)
self._site_id = site.pk
self._protocol = protocol
fully_qualified_url = property(
get_fully_qualified_url, set_fully_qualified_url,
doc="Fully qualified url (includes protocol and domain)"
)
def get_list_url(self):

return reverse(viewname)
