就这样。哦,是的,我在WinXP中。在您的URLconf中,您还没有定义根URL的视图,这就是为什么只有当您将浏览器指向以
admin/
取消对以下行的注释:
# url(r'^$', 'newgrid.views.home', name='home'),
并将“newgrid.views.home”更改为现有视图,可能会呈现包含一些临时链接的普通模板。您导航到了错误的URL。作为 现在,打开Web浏览器并转到本地域上的
/admin/
,例如http://127.0.0.1:8000/admin/
。您应该看到管理员的登录屏幕:
我知道这是很久以前提出的问题,但也许人们仍然在这里寻找同一问题的答案,就像我一样。对我来说,问题是我更改了哪个url.py。关键是更改项目url.py,而不是APP url.py文件 例如,如果您的项目名为“mysite”,而应用程序名为“polls”,则您要更改的文件位于此处:
/mysite/urls.py
不是应用程序版本(位于/polls/url.py中)
此外,您可能犯了我所犯的错误,即将/polls/url.py更改为新的“名称空间”语法,然后在对/mysite/url.py进行更改后,忘记将/polls/url.py更改回教程3(“编写更多视图”)部分中给出的原始代码()
希望这对别人有帮助。(这将是我第一次参与StackOverflow!)我也完成了本教程,在第3部分中遇到了一个问题,返回了相同的错误;我对目录结构感到困惑 我在我认为教程指定的目录中编写了url.py文件,但它是
~/mysite/url.py
,而教程实际上指定了~/mysite/mysite/url.py
教程还提示我们创建的文件~mysite/polls/urls.py
的位置正确,我应该怀疑这两组指令只列出了内部目录(polls
或mysite
)。遇到这个问题后,我不得不重新阅读教程的第1部分,但后来我终于从中理解了以下内容:
内部的mysite/
目录是项目的实际Python包
您应该在“mysite/mysite/urls.py”文件的urlpatterns类下尝试此语句“url(r'^polls/”,include('polls.urls')”,然后您就可以看到您想要什么了。我也有同样的问题,现在通过在[mysite/mysite/urls.py]中编辑url.py,以两种方式得到了解决方案或者,如果您已经在manage.py存在的路径中编辑了url.py,则将设置中的ROOT_URLCONF更改为url.py。您记得重新启动它吗?好问题。如果您指的是“manage.py runserver”,则是。我执行了CTRL-C并再次运行该命令。同样的结果。仔细阅读教程。在本教程第3部分之前,您将无法访问
/
(索引页)。谢谢你,supervacuo和dschulz。你们两个都是对的。这是我的错,教程明确指出指向/admin。我不知怎么错过了那部分。我的错。还感谢您提供解决方案的代码。
