Assuming ACT is your class name: ct = #... get the content type instance to extend here, or obtain the pk in whatever way ct_pk= ct.pk existing_ct_as_dict=ContentType.objects.get(pk=ct_pk).values()[0] act = ACT(**existing_ct_as_dict #, your extended keyword vars) act.save()
You must fetch and set all the fields in the content type, if you save from the child, and you haven't set the fields other than the pk, they will be overwritten with default values On Apr 29, 11:46 pm, medhat <[EMAIL PROTECTED]> wrote: > Hi, > > QS-rf in general and model inheritance in particular are really cool. > I have been waiting for them for a long time, thanks :-) > > I am trying now to use them.
