select_related() - suddenly to result

Hi,

I have the following query:

Buch = Buchung.objects.filter(Produkt = int(POSTvalues['Produkt']))

Later I'm using stuff like:

Buch.Produkt.Bestell_Nr

To speed things up i wan't to use select_related() on the query but no mather where I add it if I add it i get 0 entries as a result where without select_related() I do get entries.

I've tried this:

Buch = Buchung.objects.filter(Produkt = int(POSTvalues['Produkt'])).select_related()

and

Buch = Buchung.objects.select_related().filter(Produkt = int(POSTvalues['Produkt']))

Any ideas why the results are wrong if I use select_related()

cheers
