Date format localization problem (Django displays dates in format it doesn't accept)

[Ludwik Trammer]

Hi,

There is quite a serious problem with Django 1.2's format localization
and forms. At first I noticed Djnago ignores L10N date formats when
displaying dates in form fields, but calendar widgets in admin don't.
So when you try using the calendar, date format goes back and forth
between localized and unlocalized versions. I opened a ticket couple
of days ago (#13591) calling it an "usability" problem (because it is
utterly confusing to have a date format changing, when the only thing
you expected to be changed was a date).

It turned out however, that the issue is much more serious (and not
contained to Django Admin only). Look at the StackOverflow question:

http://stackoverflow.com/questions/2929388/django-1-2-dates-in-admin-forms-dont-work-with-locales-i10ntrue

It turnes out date formats for some countries, shipped with Django,
doesn't include the "universal" YYYY-MM-DD formats as accepted date
format (DATE_INPUT_FORMATS). Which at first seems logical, but in
conjunction with the fact that Django always uses the YYYY-MM-DD
format to display dates in forms, ignoring localization settings, the
result is people are getting form validating errors, when trying to
edit their models. In other words Django populates form fields with
data in format it doesn't accept itself.

Did you already try the patch I attached at
http://code.djangoproject.com/ticket/13621 ? Perhaps this solves your
problem too :-)
