If you attempt to use ``CurrentSiteManager`` and pass a field name that doesn't If you attempt to use ``CurrentSiteManager`` and pass a field name that doesn't
exist, Django will raise a ``ValueError``. exist, Django will raise a ``ValueError``.
Finally, note that you'll probably want to keep a normal (non-site-specific)
``Manager`` on your model, even if you use ``CurrentSiteManager``. As explained
in the `manager documentation`_, if you define a manager manually, then Django
won't create the automatic ``objects = models.Manager()`` manager for you.
Also, note that certain parts of Django -- namely, the Django admin site and
generic views -- use whichever manager is defined *first* in the model, so if
you want your admin site to have access to all objects (not just site-specific
ones), put ``objects = models.Manager()`` in your model, before you define
``CurrentSiteManager``.
