Django SelectDateWidget показывать только месяц и год

есть фрагмент здесь, который устанавливает день 1 (предполагая, что у вас есть DateField что это значение будет в конечном итоге, вам нужно будет получить какой-то день).

код выглядит так (на случай, если фрагменты Django исчезнут):

import datetime

from django.forms.widgets import Widget, Select
from django.utils.dates import MONTHS
from django.utils.safestring import mark_safe

__all__ = ('MonthYearWidget',)

RE_DATE = re.compile(r'(\d{4})-(\d\d?)-(\d\d?)$')

    """
    A Widget that splits date input into two <select> boxes for month and year,
    with 'day' defaulting to the first of the month.
