Question

我有一个MonthArchiveView用于我网站上的活动。如果没有提交年份和月份（例如，如果用户只访问/ events /？

，如何将存档默认设置为当前月份而不是提出例外情况？

# urls.py
url(r'^events/$', EventMonthView.as_view(), name="event_month"),
url(r'^events/(?P<year>[0-9]{4})/(?P<month>[0-9]+)/$', EventMonthView.as_view(month_format='%m'), name="event_month"),

#views.py
class EventMonthView(MonthArchiveView):
    template_name = "events.html"
    queryset = Event.objects.all()
    date_field = "date"
    allow_future = True
    month_format='%m'
    year_format='%Y'

您可以覆盖get_month和get_year方法，以便它们返回默认值：

from django.http import Http404
from django.utils.timezone import now
from django.views.generic import MonthArchiveView


class EventMonthView(MonthArchiveView):
    # ...

    def get_month(self):
        try:
            month = super(EventMonthView, self).get_month()
        except Http404:
            month = now().strftime(self.get_month_format())

        return month

    def get_year(self):
        try:
            year = super(EventMonthView, self).get_year()
        except Http404:
            year = now().strftime(self.get_year_format())

        return year

默认为MonthArchiveView中的当前月份
