剛剛更新到Django的1.4和獲得 'WSGIRequest' 對象有沒有屬性 '成功' 的錯誤

Question

我剛剛升級到Django的1.4和我得到以下錯誤：

'WSGIRequest' object has no attribute 'SUCCESS'

回溯：

File "/Users/nb/Desktop/myenv2/lib/python2.7/site-packages/django/core/handlers/base.py" in get_response 
    111.       response = callback(request, *callback_args, **callback_kwargs) 
File "/Users/nb/Desktop/spicestore/apps/account/views.py" in login 
    87.    messages.add_message(request.SUCCESS, 

Exception Type: AttributeError at /account/login/ 
Exception Value: 'WSGIRequest' object has no attribute 'SUCCESS' 

任何人都知道是什麼原因造成的？

下面是views.py的實際代碼：

messages.add_message(request.SUCCESS, 
     ugettext(u"Successfully logged in as %(user)s.") % { 
      "user": user_display(form.user) 
     } 

Answer 1

messages.add_message(request, 
       messages.SUCCESS, 
       ugettext(u"Successfully logged in as %(user)s.") % { "user": user_display(form.user) }) 

或更快：

messages.success(request, 
       ugettext(u"Successfully logged in as %(user)s.") % { "user": user_display(form.user) })
