Django的NameError

Question

我安裝Python和Django和只是想建立一個簡單的應用程序「mysite的」

我創建了根文件夾中的views.py，而我的urls.py是根/ mysite的/ 當我調用/ hello它給我以下錯誤。我應該怎麼做才能解決它？

Answer 1

c:\Python27\Django-1.5\mysite\mysite\urls.py in <module> 
         ('^hello/$', hello), 

您還沒有定義hello，我相信你既可以進口興田功能或引用它作爲一個字符串在下面的網址線

from mysite.myapp.views import hello 

或

'mysite.myapp.views.hello' 

Answer 2

變化.py

('^hello/$', hello), 

到

('^hello/$', 'views.hello'), 

，或者如果您使用的前綴然後做

('^hello/$', 'hello'), 

或做

from views import hello
