Sorry, I should've suggested that in my original snippet. The singular field name keeps giving me a brain freeze. You should seriously consider renaming that M2M field to sites if you need my help ;) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Sorry about top posting. This is about the 3rd time I've used google
groups before, but what you're saying makes sense. I'm sure I'll have
many more questions to get the hang of it!
for s in site:
ti.site.add(s)
almost worked. I got an error that the ManyRelatedManager wasn't
iterable. So I did a little research and found that
for s in site.all():
ti.site.add(s)
that works because the query set that it builds is iterable.
so that final snippet looked like this.
ti, created = TumbleItem.objects.get_or_create(content_type=ctype,
object_id=instance.id, pub_date=pub_date)
for s in site.all():
ti.site.add(s)
Thanks a ton. You've been a huge help.

Ah, I previously assumed that Article.site is a ForeignKey. See if you
had named it 'sites', it would've been easier to guess?
Anyway, change that previous ti.site.add(site) snippet to:
for s in site:
ti.site.add(s)
You could also try:
ti.site = site
But that will wipe out any previous values of site you may have
associated with the same ti instance.

I don't know how your Article and other such models are defined, by are you guaranteed to have a valid Site instance for instance.site or can that value be None? If you're in DEBUG mode (settings.DEBUG=True), you should be able to see the value of 'site' in your browser. If not, try printing 'site' and 'site.pk' just before you make the site.add() call.

Change that as follows:
if create:
ti, created = TumbleItem.objects.get_or_create(content_type=ctype,
object_id=instance.id, pub_date=pub_date)
ti.site.add(site)
Also, it's common practice to pluralize the names of your
ManyToManyFields...so in the above case it would be 'sites' instead of
'site'.
