yeah I changed my code, but is there any possibility to do this with Q, so that I can just execute one query in the end? I want to build a complex nested search/filter and Q gives me the possibility to negate queries. Is there a possibility to split those two Q's to behave in a way that would be useful for my case. > > Cheers > > Tom > thx for your tip !! > -- > You received this message because you are subscribed to the Google Groups > "Django users" group. > To post to this group, send email to django-us...@googlegroups.com. > To unsubscribe from this group, send email to > django-users+unsubscr...@googlegroups.com. > For more options, visit this group > athttp://groups.google.com/group/django-users?hl=en. -- You received this message because you are subscribed to the Google Groups "Django users" group.
