找不到語言時，Django將錯誤500重定向到404

Question

我注意到，當settings.py中引用一種語言時，如果網站中沒有適當的頁面，它將生成500個頁面。

舉個例子 ：

    LANGUAGES = (
    ('en', gettext('English')),
    ('fr', gettext('French')),
    ('it', gettext('Italian')),
    ('es', gettext('Spanish')),
    ('de', gettext('German')),
    ('el', gettext('Greek')),
    ('tr', gettext('Turkish')),
    ('ja', gettext('Japanese')),
    ('pt', gettext('Portuguese')),
    ('ar', gettext('Arabic')),
)

所以，在我的網站， en fr es de和ja被翻譯和現在在網站上。 其他人不是。 然后，如果您嘗試訪問：example.org/el/whatever，則會引發500錯誤。

我想要一個404，以便讓用戶進入網站。

是否有人對此問題有任何線索？ 還是我必須從設置中刪除語言？

非常感謝。

編輯：這是我有此錯誤的報告：

它以這樣的方式繼續（我還有2個大段），開頭為：

Traceback (most recent call last):
  File "/var/www/webapps/lib/python3.4/site-packages/cms/views.py", line 34,

和：

Traceback (most recent call last):
  File
 "/var/www/webapps/lib/python3.4/site-packages/django/core/handlers/base.py", line 150, in get_response
    response = callback(request, **param_dict)
  File "/var/www/webapps/proj_website/app/proj/views.py", line 84, in
 custom_page_not_found

Answer 1

您的views.py似乎出了點問題。

因此，您需要在出現問題的視圖中執行以下操作：

from django.http import Http404

def your_view(request):
    try:
       code_that_must_work_but_can_fail="goes here"
    except Exception, e:
       raise Http404

因此，我們在這里所做的只是將所有代碼都包裝在try中的view：except中：因此，如果somethng在try塊中出錯，它將移至except塊，並且有raise指令返回404頁面。 請在模板中創建404.html和500.html，即使有500個頁面也要有漂亮的頁面
