| + | <code python> | ||
| + | from django.contrib.sites.models import Site | ||
| + | |||
| + | def my_function_without_request(): | ||
| + | current_site = Site.objects.get_current() | ||
| + | if current_site.domain == 'foo.com': | ||

| + | <code python> | ||
| + | from django.contrib.sites.models import Site | ||
| + | from django.contrib.sites.managers import CurrentSiteManager | ||
| + | from django.db import models | ||
| + | |||
| + | class Photo(models.Model): | ||
| + | photo = models.FileField(upload_to='photos') | ||
| + | photographer_name = models.CharField(max_length=100) | ||
| + | pub_date = models.DateField() | ||
| + | site = models.ForeignKey(Site, on_delete=models.CASCADE) | ||
| + | objects = models.Manager() | ||
| + | on_site = CurrentSiteManager() | ||
| + | </code> | ||
| + | |||
| + | 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()'' | ||
