我如何才能知道我在Django中遇到了哪些500錯誤？

當我在我的Django應用程序訪問的網頁（http://68.123.151.234/static/quickstart.html）通過Django的催生了一個服務器上提供服務，頁面讀取我如何才能知道我在Django中遇到了哪些500錯誤？

A server error occurred. Please contact the administrator.

我收到此回溯。

TemplateDoesNotExist: 500.html

此追溯只告訴我，我需要一個500模板 - 而不是實際的服務器錯誤。我如何知道服務器錯誤是什麼？

我檢出了Django文檔（https://docs.djangoproject.com/en/1.4/topics/http/views/），它指導我創建一個500錯誤模板作爲潛在的解決方案。但是，它沒有提供關於如何在這樣的模板中顯示錯誤的指示。

你的'DEBUG'是否設置爲'True'？ Django不會以'DEBUG'設置爲'False'顯示回溯。 – dgel

正如Alasdair所說，一個基本的500.html方便有用，可能會揭示出一些敏感的東西。

但是，如果調試了以負責任的方式在網絡是客觀的，一個基本的nondefault500.html模板爲您的網站模板目錄看起來像

<html><head><body> 
<!-- starting with sys.exc_info but hey, it's python --> 
Type: {{ type }} <br /> 
Value: {{ value }} <br /> 
Traceback: {{ traceback }} <br /> 
</body></head></html>

和新的處理程序將填充這種情況下這樣：

def this_server_error(request, template_name='nondefault500.html'): 
    """ 
    500 error handler. 

    Templates: `500.html` 
    Context: sys.exc_info() results 
    """ 
    t = loader.get_template(template_name) # You need to create a 500.html template. 
    ltype,lvalue,ltraceback = sys.exc_info() 
    sys.exc_clear() #for fun, and to point out I only -think- this hasn't happened at 
        #this point in the process already 
    return http.HttpResponseServerError(t.render(Context({'type':ltype,'value':lvalue,'traceback':ltraceback})))

，有需要是由URL配置調整，

handler500 = 'mysite.views.this_server_error'

謝謝！這就是訣竅。 – dangerChihuahua007

我相信你需要一個500.html模板，當DEBUG設置爲False。

創建一個並把它放在你的模板目錄

將顯示給用戶，只要有一個500錯誤。

如果您正在測試您的網站，請設置DEBUG=True然後Django將顯示回溯。

一旦網站正常運行，您可能不希望在錯誤頁面上顯示回溯，因爲它可能包含敏感信息。

如果添加500個模板。然後，Django將向ADMINS設置中列出的用戶發送包含回溯的電子郵件。

有關更多信息，請參閱Error Reporting上的文檔。

TemplateDoesNotExist: 500.html

我想你應該在你的模板目錄中創建500.html。
