Django：反向函数失败并出现异常

我正在关注 Django 教程，但在教程的第 4 部分遇到了错误。我已经到了编写vote视图的部分，它使用reverse重定向到另一个视图。由于某种原因，反向失败，但出现以下异常：

import() 参数 1 必须是字符串，而不是实例方法

目前我的项目的 urls.py 看起来像这样：

from django.conf.urls.defaults import *
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    (r'^polls/', include('mysite.polls.urls')),
(r'^admin/(.*)', include(admin.site.root)),
)

应用程序 urls.py 是：

from django.conf.urls.defaults import *

urlpatterns = patterns('mysite.polls.views',
     (r'^$', 'index'),
     (r'^(?P<poll_id>\d+)/$', 'details'),
     (r'^(?P<poll_id>\d+)/results/$', 'results'),
     (r'^(?P<poll_id>\d+)/vote/$', 'vote'),
)

投票视图是：（我已将其简化为仅包含错误的行）

def vote(request, poll_id):
    return HttpResponseRedirect(reverse('mysite.polls.views.results', args=(1,)))

当我从项目的 urls.py 中删除管理 urls 时，即使其变为：

urlpatterns = patterns('',
    (r'^polls/', include('mysite.polls.urls')),
#(r'^admin/(.*)', include(admin.site.root)),
)

它有效。

我尝试了很多事情，但无法理解我做错了什么。

原文

I'm following the Django tutorial and got stuck with an error at part 4 of the tutorial. I got to the part where I'm writing the vote view, which uses reverse to redirect to another view. For some reason, reverse fails with the following exception:

import() argument 1 must be string, not instancemethod

Currently my project's urls.py looks like this:

from django.conf.urls.defaults import *
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    (r'^polls/', include('mysite.polls.urls')),
(r'^admin/(.*)', include(admin.site.root)),
)

and the app urls.py is:

from django.conf.urls.defaults import *

urlpatterns = patterns('mysite.polls.views',
     (r'^
And the vote view is: (I've simplified it to have only the row with the error)
def vote(request, poll_id):
    return HttpResponseRedirect(reverse('mysite.polls.views.results', args=(1,)))

When I remove the admin urls include from the project's urls.py, i.e. making it into:
urlpatterns = patterns('',
    (r'^polls/', include('mysite.polls.urls')),
#(r'^admin/(.*)', include(admin.site.root)),
)

it works. 
I've tried so many things and can't understand what I'm doing wrong.

     (r'^(?P<poll_id>\d+)/
And the vote view is: (I've simplified it to have only the row with the error)
