Well, I'm not sure what the matter was, maybe some bad cache or
something, but the problem seems to have corrected itself. Weird!

Re: Trouble with DateField

Hi Brian,

Yes, I've also made certain that the value returned for effective date
from form.cleaned_data['effective_date'] is a valid Python datetime
object.

Something seems to be amiss. The exception is happening in: django/db/
models/fields/__init__.py in to_python, line 473

If I put a print statement in there to print the 'value' variable
handed to the 'to_python' function, it doesn't return None or the
value, in fact it prints an empty line, which is making me think it's
an empty string...?

Here:

activity_code.effective_from = form.cleaned_data['effective_from']

You are assigning a string to what I assume is a models.DateTimeField
or DateField. I don't think that works. You need to turn the string
into a Python datetime object first. I think this is done
automatically for you if you were using a ModelForm.

Trouble with DateField

[Brandon Taylor]

Hi everyone,

I need a sanity check here. I'm using a jQueryUI DatePicker, with the
dateFormat option set to 'yy-mm-dd', which is returning a date in -
MM-DD format, if I check my request.POST values.

I have a DateField - "effective_from", on my model, and am using a
corresponding ModelForm. When I check the form.cleaned_data
['effective_from'], I get a Python datetime object as: 2009-04-13.

However, I'm getting an exception error for the view, saying:
ValidationError at /codes/create/
Enter a valid date in -MM-DD format.

I have also parsed the date by hand:
, MM, DD = map(int, request.POST['effective_from'].split('-'))
effective_from = datetime.date(, MM, DD)


The portion of the view in question is:
form = ActivityCodeForm(request.POST)
if form.is_valid():
activity_code = form.save(commit=False)
activity_code.created_by = request.user
activity_code.category = Category.objects.get(pk=int
(form.cleaned_data['kategory']))
activity_code.effective_from = form.cleaned_data
['effective_from']
activity_code.slug = slugify(form.cleaned_data['title'])
activity_code.save()

Can anyone see what I'm doing wrong here?
TIA,
Brandon
