python选择日期控件_django中的自定义日期控件？

在当前基于python和django的应用程序中，我为date创建了一个自定义小部件。在from datetime import date

from django.forms import widgets

class DateSelectorWidget(widgets.MultiWidget):

def __init__(self, attrs=None):

# create choices for months, years

# example below, the rest snipped for brevity.

years = [(year, year) for year in range(1945, 2016)]

months = [(1,'Jan'),(2,'Feb')]

_widgets = (

widgets.Select(attrs=attrs, choices=months),

widgets.Select(attrs=attrs, choices=years),

)

super(DateSelectorWidget, self).__init__(_widgets, attrs)

def decompress(self, value):

if value:

return [value.month, value.year]

return [None, None]

def format_output(self, rendered_widgets):

return u''.join(rendered_widgets)

def value_from_datadict(self, data, files, name):

datelist = [

widget.value_from_datadict(data, files, name + '_%s' % i)

for i, widget in enumerate(self.widgets)]

try:

D = date(day=1, month=int(datelist[0]),

year=int(datelist[1]))

except ValueError:

return ''

else:

return str(D)

当我把表单中的一些字段加载为空的时候，我返回的表单是空的。在
