Comment (by brosner):
Ok, I have looked a bit more deeply into this problem. The test case
provided above is slightly misleading. The data provided is invalid data
and the reporter is expecting this to fail. When in reality that isn't a
good test case. Here is an improved case clearly showing the problem:
{{{
# Handle when forms are missing in the POST data
##############################
# See http://code.djangoproject.com/ticket/8171
###############################
>>> ChoiceFormSet = formset_factory(Choice)
>>> data = {
... 'choices-TOTAL_FORMS': '3', # the number of forms rendered
... 'choices-INITIAL_FORMS': '0', # the number of forms with initial
data
... 'choices-0-choice': 'Calexico',
... 'choices-0-votes': '100',
... # choices-1, choices-2, choices-3 are missing. Possibly due to
some
... # Javascript add/delete of the elements.
... 'choices-4-choice': 'The Decemberists',
... 'choices-4-votes': '200',
... 'choices-5-choice': '',
... 'choices-5-votes': '',
... }
>>> formset = ChoiceFormSet(data, auto_id=False, prefix='choices')
>>> formset.is_valid()
True
>>> [form.cleaned_data for form in formset.forms]
[{'votes': 100, 'choice': u'Calexico'}, {'votes': 200, 'choice': 'The
Decemberists'}, {}]
}}}
