| - | If you don’t have access to the request object, you can use the ''get_current()'' method of the Site model’s manager. You should then ensure that your settings file does contain the ''SITE_ID'' setting. | + | <code python> |

| - | <code> | + | |
| from django.contrib.sites.models import Site | from django.contrib.sites.models import Site | ||
| + | from django.contrib.sites.managers import CurrentSiteManager | ||
| + | from django.db import models | ||
| - | def my_function_without_request(): | + | class Photo(models.Model): |

| - | if current_site.domain == 'foo.com': | + | photographer_name = models.CharField(max_length=100) |
| - | # Do something | + | pub_date = models.DateField() |
| - | pass | + | site = models.ForeignKey(Site, on_delete=models.CASCADE) |

| + | Having this we can: | ||
| + | * Query all Photo objects in the database with ''Photo.objects.all()''. | ||
| + | * Query only the Photo objects associated with the current site (according to the ''SITE_ID''): ''Photo.on_site.all()'' | ||
