It creates a new SQL statement that returns one objects,
without ever 
having done the original query, so there is no performance
hit.  To do 
the PK query client side would mean you'd have to replicate
all the 
features of the DB in Python.

Hi

Thanks for your responses. Thats what I thought, just wanted
to make
sure. The all() just seems unitutive to me, but given that
Djangos
syntax is so easy, a little bit of something here and there
is no
biggie.

Thanks again.

PS I just posted a patch for the generic views on the
developers list
to add a template model name: http://code
.djangoproject.com/ticket/1399
