Comment:

 My understanding is that only form fields (rather than model fields)
 handle those formats (e.g.
 
[https://github.com/django/django/blob/90c3b11e873a326219a68c14a3b5dca0181e7b3c/django/forms/fields.py#L409
 DateField]).

 Per the Django Docs, in settings.py if I set USE_L10N to false, I should
 be able to override the supported date formats. My settings.py has the
 following:



 {{{
 LANGUAGE_CODE = 'en-us'

 TIME_ZONE = 'UTC'

 USE_I18N = False

 USE_L10N = False

 USE_TZ = False

 DATE_INPUT_FORMATS = [
 '%Y-%m-%d', '%m/%d/%Y', '%m/%d/%y', # '2006-10-25', '10/25/2006',
 '10/25/06'
 '%b %d %Y', '%b %d, %Y',# 'Oct 25 2006', 'Oct 25, 2006'
 '%d %b %Y', '%d %b, %Y',# '25 Oct 2006', '25 Oct, 2006'
 '%B %d %Y', '%B %d, %Y',# 'October 25 2006', 'October 25,
 2006'
 '%d %B %Y', '%d %B, %Y',# '25 October 2006', '25 October,
 2006'
 ]
 }}}

 I have a model that looks like the following:

 {{{
 class DateTest(models.Model):
 date = models.DateField(blank=True, null=True)
 }}}

 When I run the following command, i get an error:


 {{{
