Django l10n dateformat只适用于en

Question

我正在使用l10n设置来翻译我的网站。 一切正常，除了浏览器语言设置为“en” 当我打印get\u language（）并获取语言日期格式时。它们返回正确的值（'en'，'m/d/Y'）

但是，当我检查模板中的日期时，它是Y-m-d

对于其他任何语言，它都能正常工作

# settings.py
LANGUAGE_CODE = 'nl-NL'
USE_I18N = True
USE_L10N = True

# forms
# DatePickerForm is needed to also setup the bvootstrap-datepicker
class DatePickerForm(forms.Form):
""" hidden inputs to make bootstrap-datepicker work with django locale """

FORMAT_MAP = {
    # 'locale': [datepicket_lang, datepicker-pattern]
    # 'en-US': ['en', 'mm/dd/yyyy']
    'en': ['en', 'mm/dd/yyyy'],
    'nl': ['nl', 'd-m-yyyy'],
    'pl': ['pl', 'dd.mm.yyyy'],
    'de': ['de', 'dd.mm.yyyy'],
}

locale_language = forms.CharField(widget=forms.HiddenInput())
locale_date_format = forms.CharField(widget=forms.HiddenInput())

def __init__(self, *args, **kwargs):
    self.locale_language = get_language()
    super(DatePickerForm, self).__init__(*args, **kwargs)
    self.initial['locale_language'] = self.datepicker_language()
    self.initial['locale_date_format'] = self.datepicker_format()
    print self.locale_language

def datepicker_format(self):
    if self.locale_language in DatePickerForm.FORMAT_MAP:
        return DatePickerForm.FORMAT_MAP[self.locale_language][1]
    else:
        return DatePickerForm.FORMAT_MAP['nl'][1]

def datepicker_language(self):
    if self.locale_language in DatePickerForm.FORMAT_MAP:
        return DatePickerForm.FORMAT_MAP[self.locale_language][0]
    else:
        return DatePickerForm.FORMAT_MAP['nl'][0]

class TotalForm(DatePickerForm):
""" date range input for totals """

begin = forms.DateField(label='')
end = forms.DateField(label='')

有人知道为什么会出问题吗？你知道吗
