我正在尝试将 django-schedule 合并到我的项目中。Django-schedule 的源代码在这里。我不喜欢这些网址,因为它们都捕获了一个蛞蝓。我的项目将只允许每个用户使用一个日历,因此捕获 sl 没有意义。因此,我像这样包装了 django-schedule 视图(使用当前用户查找 slug,并将其传递给 django-schedule 的视图):
from schedule.views import calendar_by_periods
from schedule.models import Calendar
from schedule.periods import Month
def cal_by_periods_wrapper(view):
def new_view(request, *args, **kwargs):
kwargs['calendar_slug'] = Calendar.objects.get_calendars_for_object(obj=request.user, distinction="owner")[0].slug
return view(request, *args, **kwargs)
return new_view
这是 urls.py 中的相关部分:
urlpatterns = patterns('',
url(r'^$',
cal_by_periods_wrapper(calendar_by_periods),
name = "month_calendar",
kwargs={'periods': [Month], 'template_name': 'schedule/calendar_month.html'}),
这可以正常工作,直到它遇到 django-schedule prev_url 中包含的模板标签之一:
@register.simple_tag
def prev_url(target, slug, period):
return '%s%s' % (
reverse(target, kwargs=dict(calendar_slug=slug)),
querystring_for_date(period.prev().start))
此功能引发:
TemplateSyntaxError at /teacher/calendar/
Caught an exception while rendering: Reverse for 'month_calendar' with arguments
'()' and keyword arguments '{'calendar_slug': u'asdf'}' not found.
我怎样才能包装这个视图并仍然使反向调用工作?
