Forms DateField show_hidden_initial USE_L10N = False and custom DATE_INPUT_FORMATS

[dibrovsd@…]

Hi.

if settings is:

• USE_L10N = False
• DATE_INPUT_FORMATS = ('%d.%m.%Y', '%Y-%m-%d')

then format in DateInput and HiddenInput (default hidden_widget for DateField) is different:

• DateInput: '01.01.2014'
• HiddenInput: '2014-01-01'

Field._has_changed('2014-01-01', '2014-01-01') always return True in form.changed_data

For default DATE_INPUT_FORMATS, DateInput use '%Y-%m-%d' (DATE_INPUT_FORMATS[0] for USE_L10N = False)
But if DATE_INPUT_FORMATS[0] != '%Y-%m-%d'

format HiddenInput != format DateInput

Test case:

from django import forms
from datetime import date

class TestForm(forms.Form):
    date_field = forms.DateField(show_hidden_initial=True)

form = TestForm(initial={'date_field': date.today()})

print form.as_ul()

Fix:
# add HiddenDateInput
class HiddenDateInput(forms.DateInput):

is_hidden = True
input_type = 'hidden'

# set HiddenDateInput for default hidden_widget in DateField
class DateField(fields.DateField):

hidden_widget = widgets_custom.HiddenDateInput
