我已经阅读了很多答案,但没有人回答我的确切问题。新手。 Django教程(来自django网站)卡在第2部分 - admin

我做了第一部分,民意调查。我开始部分2,管理员,但是,runserve后,当我尝试存取权限的页面,这里是错误我得到(我的项目的名字是约翰):

Page not found (404) 
Request Method: GET 
Request URL: http://127.0.0.1:8000/ 
Using the URLconf defined in john.urls, Django tried these URL patterns, in this order: 
^admin/ 
The current URL, , didn't match any of these. 
You're seeing this error because you have DEBUG = True in your Django settings file. `` 

我的代码 - urls.py:

from django.conf.urls import patterns, include, url 

# Uncomment the next two lines to enable the admin: 
from django.contrib import admin 
admin.autodiscover() 

urlpatterns = patterns('', 
    # Examples: 
    # url(r'^$', 'newgrid.views.home', name='home'), 
    # url(r'^newgrid/', include('newgrid.foo.urls')), 

    # Uncomment the admin/doc line below to enable admin documentation: 
    # url(r'^admin/doc/', include('django.contrib.admindocs.urls')), 

    # Uncomment the next line to enable the admin: 
    url(r'^admin/', include(admin.site.urls)), 
) 

Models.py:

from django.db import models 
import datetime 
from django.utils import timezone 

# Create your models here. 
from django.db import models 

class Poll(models.Model): 
    question = models.CharField(max_length=200) 
    pub_date = models.DateTimeField('date published') 
    def __unicode__(self): 
     return self.question 
    def was_published_recently(self): 
     return self.pub_date >= timezone.now() - datetime.timedelta(days=1) 


class Choice(models.Model): 
    poll = models.ForeignKey(Poll) 
    choice = models.CharField(max_length=200) 
    votes = models.IntegerField()

     return self.choice

您是否记得重新启动它? – 2012-08-10 21:55:56

很好的问题。如果你指的是:“manage.py runserver”,那么是的。我做了CTRL-C并再次运行该命令。同样的结果。 – 2012-08-10 21:57:52

请仔细阅读本教程。在本教程的第3部分之前,您将无法访问'/'(索引页)。请参阅http://stackoverflow.com/questions/11832178/404-error-in-django-when-visiting-runserver-returns-no-errors-though/11832382#11832382 – supervacuo 2012-08-10 21:58:37

您正在导航到错误的URL。作为the tutorial says

现在,打开Web浏览器并转到/admin/在您的本地域名 - 例如http://127.0.0.1:8000/admin/。您应该看到管理员的登录屏幕:

在URLconf,你还没有定义的根URL一个观点,这就是为什么,如果你的浏览器指向的URL与admin/

取消注释开始下面的行应用程序将只工作:

# url(r'^$', 'newgrid.views.home', name='home'), 

并将'newgrid.views.home'更改为现有视图,可能是呈现包含一些临时链接的纯模板的东西。

谢谢你,supervacuo和dschulz。你们俩都是对的。这是我的不好,教程明确指出/ admin。我不知何故错过了那部分。我的错。还要感谢解决方案的代码。 – 2012-08-10 22:05:37

我知道这是很久以前问过的,但也许人们仍然在寻找对我来说是同一个问题的答案。对我来说,我做的问题是,其中 urls.py我改变了。关键是更改PROJECT urls.py,而不是APP urls.py文件。

例如,如果你的项目被称为“mysite的”和APP是“民意调查”你想改变就设在这里的文件:

/mysite/urls.py 

并非该应用的版本(位于/调查/网址的.py)。

此外,您可能会发生我执行的错误,即将/polls/urls.py更改为新的“命名空间”语法,然后,在对/mysite/urls.py进行更改后,忘记更改/polls/urls.py回到教程3(https://docs.djangoproject.com/en/1.7/intro/tutorial03/)的“编写更多视图”部分给出的原始代码

希望这可以帮助某人。 (这将是我第一次贡献给StackOverflow!)

我也通过本教程工作,并在第3部分中返回了相同的错误;我的困惑是目录结构。

我写过网址。目录中的文件的py我以为指定的教程,但它是~/mysite/urls.py而教程实际上指定~/mysite/mysite/urls.py

文件~mysite/polls/urls.py,该教程还提示我们创建,位于正确的,我应该一直怀疑这两组指令只列出了内部目录(pollsmysite)。我不得不重新阅读教程的第1部分有这个问题后,但后来我终于从它的理解下面的文字:

mysite/目录是实际的Python包为您的项目。

您应该在“mysite/mysite/urls.py”文件中的urlpatterns类下尝试使用此语句“url(r'^ polls /',include('polls.urls'))”,然后您可以看到什么ü希望

我有同样的问题,现在得到了解决两种方式,通过编辑[mysite的/ mysite的/ urls.py]的urls.py或改变ROOT_URLCONF在设置urls.py如果您已经在manage.py所在的路径中编辑了urls.py。
