Dates are somehow cached

[adi-]

I need to enable only few dates in calendar and I initiate a form like this:

widgets = {
            'pickup_date': DatePickerInput(
                options=FlatpickrOptions(
                    enable=get_working_days_formated(
                        arrow.get(timezone.now().date()).shift(days=1),
                        arrow.get(timezone.now().date()).shift(days=2)
                    )
            ),
        }

Not sure if this is DatePicker problem or Django's/Python's caching, but when one day passes in real date, DatePicker still uses the same dates as were compiled for the first time. Any clues what could be wrong?

Hi, I don't know if you still need this, but I've faced a similar thing in the past. The issue is that your piece of code is probably executed when the server starts and doing so it fixes the result of timezone.now(). To solve the problem you need to provide the result in a lazy way. You can use lazy wrapper from django.utils.functional and instead of using timezone.now(), you use lazy(timezone.now, timezone.datetime)().

I don't rememberer now exactly, but it was a mistake of a initial value cached by python itself, I guess:)
