Django 1.8 AttributeError：模块没有属性'urls'

我正在做一个练习来显示“hello world！”，但是当我打开网站时，django发出了一个异常。我该如何解决这个问题？Django 1.8 AttributeError：模块没有属性'urls'

唯一的例外是：

AttributeError at/
module 'apps.release_news' has no attribute 'urls' 
Request Method: GET 
Request URL: http://127.0.0.1:8000/ 
Django Version: 1.8.7 
Exception Type: AttributeError 
Exception Value:  
module 'apps.release_news' has no attribute 'urls' 
Exception Location: C:\software\development\PythonProject\DemoGuitarProject\DemoGuitarProject\urls.py in <module>, line 24

@Sayse我想刚才删除的密钥，但它仍然没有给予例外的工作：提高ImproperlyConfigured（以下简称“ SECRET_KEY设置不能为空。“） –

@KamiWan，@Sayse希望你从你发布的代码中移除SECRET_KEY，它可能被利用。您绝对不应该在公开可访问的代码中包含这样的敏感数据。 – mic4ael

@ mic4ael，@ Sayse我已经做到了。谢谢你提醒我。 –

从代码DemoGuitarProject/urls.py

from apps import release_news

读取文件apps/release_news/__init__.py

我猜这个文件是空的。添加到该文件：

from apps.release_news import urls

或更改DemoGuitarProject/urls.py

from apps.release_news import urls as release_news_urls 

urlpatterns = [ 
    url(r'^admin/', include(admin.site.urls)), 
    url(r'^release_news/', include(release_news_urls)), 
]

你的猜测是正确的，你的建议真的有用！我仍然对为什么使用'from apps import release_news'这个语句不能让django在release_news目录中找到urls.py文件感到困惑？ –
