附表标签的功能：

@register.inclusion_tag('schedule/_create_event_options.html', takes_context=True)

    context.update({
        'calendar': calendar,

    }
    context['create_event_url'] = '%s%s' % (
        reverse('calendar_create_event', kwargs=lookup_context),
        querystring_for_date(slot))
    return context

url：

re_path(r'^event/create/(?P<calendar_slug>[-\w]+)/$',
        CreateEventView.as_view(),
