django - 在 MonthArchiveView 中默认为当前月份

Question

我有一个 MonthArchiveView 用于我网站上的事件。如果没有提交年份和月份(例如，如果用户仅访问/events/？

# 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
