Hi Jacob,
I've just updated to revision 3654.
I was trying to populate a context with two different lists of news
entries. The second list shouldn't display entries already shown in the
first, so I used exclude with 'id__in' to separate the results.
Also, I'm using a custom manager to show only public entries.
The problem appeared when the first list was empty, the second list
filter gives an error.
Here is the relevant code:
def home(request):
# Initialize the context
context = []
# Get 5 hot news
context['hot_news_list'] = Entry.public.filter(hot=True)[:5]
# Get the hot news IDs to ignore in the next queries
ids = [entry.id for entry in context['hot_news_list']]
# Get 4 simple news
context['simple_news_list'] = Entry.public.exclude(id__in=ids)[:4]
return render_to_response('home.html', context)
