+==== Querying depending on the site ====
+<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()''
