Initial value is not displayed on forms.DateField with widget input type="date" when localized

[binoy...@gmail.com]

Hi

I have a form field forms.DateField and widget as follows

class CustomDateInput(forms.DateInput):
    input_type = 'date'

valid_from = forms.DateField(
        label=_("Valid from"), widget=CustomDateInput(), required=False, localize=True)

But the date is not displayed by the browser when the language is German(de). The field is rendered as follows with in:

<input type="date" name="valid_from" value="25.10.2021" class="form_item" id="id_valid_from">

But the browser is not display the initial value to the user, instead shows mm/dd/yyyy when the system language is English and dd.mm.yyyy when the system language is German.

I have also tried not passing the localize form field argument as well as localize off template tag, but both didn't work. 

I could resolve the issue by rending the field manually and setting the date form to  yyyy-mm-dd.

Is it a browser issue or as the date input supports only value in yyyy-mm-dd?

Python version: 3.8. 10 and django: 3.0.14

Hello,

I think you need a entry in settings.py with USE_L10N = True

You can make fix format in settings.py with DATE_FORMAT = 'd.m.Y'

Hi

Sorry, I missed that part.

class CustomDateInput(forms.DateInput):
    input_type = 'date'

    format = get_format(forms.DateInput.format_key) + ["%d.%m.%Y"]

and USE_L10N = True in settings.

Hello,

but why you configure this with a own class? You can configure this in settings.py...
