Django form: Allow user to insert a date in dd-mm-yyyy format and then convert in yyyy-mm-dd

[MarcoS]

Hi all,
I'm implementing a form in django with a DateField field in forms.py.
My purpose is to allow a user to insert a date in european format (dd/
mm/yyyy) and then, obviously, convert it in the yyyy/mm/dd format to
let's django check if it's a valid date and save it in a db.

currently I've a javascript code that intercept the "submit command"
in the html form and converts the date in yyyy/mm/dd.

My ask is: It's possible to implement the convertion, not in a
javascript function, but directly in views.py or forms.py before
cleaning the date?

Hi,

check the DateField form widget. It allows you to specify what format
the date should be in.

Hi Adi, thanks for your reply!

I had just tried the DateField.input_formats, but the problem was that
I'm using the date admin widgets.
If I specify input_formats like: '%d.%m.%y', I can't use the admin
widgets 'cause it insert the date in the format: '%Y-%m-%d' (how you
can see in django/contrib/admin/media/js/admin/DateTimeShortcuts.js
line 239)...

Marco,

look at my solution here: http://groups.google.be/group/django-users/msg/50eba033580c7536

to use the admin date picker, you need to tell your widget to add the
correct attrs so the last line becomes something like this:

super(DateWidget, self).__init__(format=settings.DATE_OUTPUT_FORMAT,
attrs={'class': 'vDateField'})

good luck,

Koen

The Problem with the Admin is that the DateField doesn't respect any output formats.

Thanks for your replies, Koeb and Ady.

Ady, if I understood I've to place the code from

http://code.djangoproject.com/attachment/ticket/3672/ticket%233672--patch-test.diff

to

- python/site-packages/django/forms/forms.py and
- python/site-packages/django/forms/widgets.py

and then I call the form with the follow field:

date = forms.DateField(widget=DateTextInput(format='d/m/y'),
input_formats=['%d/%m/%y'])

It's correct?

Yes, basically. 

and then I call the form with the follow field:

date = forms.DateField(widget=DateTextInput(format='d/m/y'),
input_formats=['%d/%m/%y'])

It's correct?

In the diff file there are some regression tests which show you how to use the Fields.
