Django error object has no attribute 'update'

Question

UPDATE

I was doing some maintenance on the server and rebooted... once it came back the code worked just fine... which actually makes me to worry ju

Answer 1

I have had similar case, but it worked when using construction like:

this_spot = Spot.objects.filter(pk=obj.spot.pk)
this_spot.update(friendly_rate=rating_to_be_persisted)

but not working in case, where I wanted access directly single instance, e.g from foreign key side class. Returning 'Spot' object has no attribute 'update'.

The reason is simply the way update() works described in django documentation:

The way around is approach like shown on the django site:

>>> b = Blog.objects.get(pk=1)

# Update all the headlines belonging to this Blog.
>>> Entry.objects.select_related().filter(blog=b).update(headline='Everything is the same')
