Hi all,
I'd like to add a small note of warning about queryset caching in dos,
in topics/db/queries.txt "Caching and QuerySets" section,
something like:
Keep in mind when looping through a queryset and altering data that
might be returned by the same queryset, that instances might not
be "fresh".
You might want to refresh the instance before calling some table-wide
data-altering
method on it::
>>> for obj in Entry.objects.all():
>>> obj = Entry.objects.get(pk=obj.pk)
>>> obj.alter_some_other_entries()
Should I open a ticket or maybe it's a too specific use-case?
Cheers,
Marco
