I encountered this while trying to migrate from 1.10 to 1.11, ModelFormSet
that was valid on 1.10 became invalid on 1.11.
Here's test case:
{{{
from django.db import models
from django.test import TestCase
from django.forms.models import modelformset_factory
class Price(models.Model):
quantity = models.PositiveIntegerField()
class ModelFormsetTest(TestCase):
def test_modelformset_validate_min_and_initial(self):
data = {
'form-TOTAL_FORMS': '2',
'form-INITIAL_FORMS': '0',
'form-0-quantity': '1',
}
FormSet = modelformset_factory(Price, fields=('quantity',),
min_num=1, validate_min=True)
formset = FormSet(data, initial=[{'quantity': 1}])
self.assertTrue(formset.is_valid())
}}}
Bisected to f5c6295797b8332134fd89e0209a18a1d1d45e0c.
