django - 你如何将 Django 的 SelectDateWidget 的顺序更改为日、月、年？

Question

这是表格:

from django.forms.extras.widgets import SelectDateWidget


class EntryForm(forms.ModelForm):

    class Meta():
        model = Entry

    def __init__(self, *args, **kwargs):
        super(EntryForm, self).__init__(*args, **kwargs)
        this_year = datetime.date.today().year
        years = range(this_year-100, this_year+1)
        years.reverse()
        self.fields["date_of_birth"].widget = SelectDateWidget(years=years)

出生日期字段是这样呈现的



如何更改它以使其呈现为日、月、年？

从这个小部件的源代码我看到下拉的顺序是由 DATE_FORMAT 定义的环境:

    format = get_format('DATE_FORMAT')
    escaped = False
    output = []
    for char in format:
        if escaped:
            escaped = False
        elif char == '\\':
            escaped = True
        elif char in 'Yy':
            output.append(year_html)
        elif char in 'bFMmNn':
            output.append(month_html)
        elif char in 'dj':
            output.append(day_html)    

尝试改变 DATE_FORMAT在 settings.py 到 j N, Y例如。
