DateField with Django

[Edgard Matos]

Hi!

I have a model with a DateField and I'm setting the input_formats properties to "%d/%m/%Y":
birth_date = forms.DateField(input_formats=("%d/%m/%Y",))

When I go add a object in this format ("%Y/%m/%d"), the django validation validate with sucess.

But when I edit my object:
form = UserForm(instance=stored_user)
Django fill the DateField in this format: ("%Y-%m-%d")

How I do to Django fill the field in this format ("%Y/%m/%d") ?

Anybody help me?
Thanks!

Please be more patient, you've scarcely waited 3 hours before sending another email.  Remember that everyone who replies here is a volunteer, and we are scattered around the world, across many time zones, so try to wait at least a full day before "bumping" a thread.

You have reason Alex.

I'm sorry.

Hello people,

It has been over a month do I'd like to raise the same question again,
with all due respect.

Does anybody know how to control a form's output format of a stored
DateField? Unfortunately, different countries use different customs to
represent dates and I'd like to represent the date in another
international format (%d-%m-%Y). Any help would be very much
appreciated!

A major thanks,

Wim

I use the following combination of formfield and widget:

as formfield:

class DateFormField(forms.DateField):
def __init__(self, input_formats=None, *args, **kwargs):
super(DateFormField, self).__init__(*args, **kwargs)
self.input_formats = input_formats or
settings.DATE_INPUT_FORMATS

def clean(self, value):
super(forms.DateField, self).clean(value)
if value in forms.fields.EMPTY_VALUES:
return None
if isinstance(value, datetime.datetime):
return value.date()
if isinstance(value, datetime.date):
return value
for format in self.input_formats:
try:
y, m, d = time.strptime(value, format)[:3]
if y == 1900:
y = datetime.datetime.now().year
return datetime.date(y, m, d)
except ValueError:
continue
raise forms.util.ValidationError(self.error_messages
['invalid'])

note that I defined the input formats in my settings as

DATE_INPUT_FORMATS = (
'%d/%m/%Y', '%d/%m/%y', # '25/10/2006', '25/10/06'
'%d/%m', # '25/10'
'%Y-%m-%d', # '2006-10-25'
)

subclassing clean() allows me to enter dates without a year specified.
If you don't need this you can leave out the clean method definition.


and as widget:

class DateWidget(forms.DateTimeInput):
def __init__(self, attrs={}):
super(DateWidget, self).__init__
(format=settings.DATE_OUTPUT_FORMAT)

where my setting for the output format is:

DATE_OUTPUT_FORMAT = '%d/%m/%Y'

(to be honest my real widget also defines some media to use the jquery
datepicker)

Maybe this helps somebody,

cheers,

Koen
