「海峽」對象有沒有屬性「決心」當訪問管理站點

Question

我不斷收到此錯誤： 「海峽」對象有沒有屬性「決心」

試圖訪問Django管理站點時

，我可以」不知道爲什麼 。 我有我的項目中有自己的admin.py文件的應用程序。 這可能導致它嗎？ 這裏是我的urls.py：

from django.conf.urls.defaults import * 
import settings 
from django.contrib.auth.views import login, logout 
from views import index, simple, complex 
from django.views.generic.simple import direct_to_template 

# Uncomment the next two lines to enable the admin: 
from django.contrib import admin 
admin.autodiscover() 
urlpatterns = patterns('', 
    # Example: 
    # (r'^django_jchat/', include('django_jchat.foo.urls')), 
    # Uncomment the admin/doc line below and add 'django.contrib.admindocs' 
    # to INSTALLED_APPS to enable admin documentation: 
    (r'^admin/doc/', include('django.contrib.admindocs.urls')), 
    # Uncomment the next line to enable the admin: 
    (r'^admin/', include(admin.site.urls)), 

...

根據出色答卷張貼在這裏： http://redsymbol.net/articles/django-attributeerror-str-object-no-attribute-resolve/

通常有這個錯誤的幾個來源：

1. 你錯過了 '模式關鍵字'：

   urlpatterns = ('', 
   (r'^$', direct_to_template, {'template' : 'a.html'}), 
   # ... 
   

   本應改爲：

   urlpatterns = patterns('', 
   (r'^$', direct_to_template, {'template' : 'a.html'}), 
   # ... 
   

   注意，在Django 1.8+，這是更好地使用正則表達式，而不是patterns的列表。

   urlpatterns = [ 
       (r'^$', direct_to_template, {'template' : 'a.html'}), 
       ... 
   ] 
   

2. 你在一些元組錯過了一個逗號，如：

   (r'^hello/$' 'views.whatever') 
   

3. 你的評論了一些網址（）s，使用三引號

4. 你不小心留下一個右括號中錯誤的地方：

   (r'^(?P\d{4})/$', 'archive_year', entry_info_dict), 'coltrane_entry_archive_year', 
   

   而不是：

   (r'^(?P\d{4})/$', 'archive_year', entry_info_dict, 'coltrane_entry_archive_year'), 
   

5. 您設置ROOT_URLCONF是list

6. 當從模式遷移元組，你忘了刪除模式的空''參數常規列表。

請仔細檢查，如果你沒有在你的代碼中的這種情況之一。

Answer 2

對於我來說，這引起了問題：

urlpatterns = patterns('', 
    url(r'^all/$', 'album.views.albums'), 
    """ 
    url(r'^create/$', 'album.views.create'), 
    url(r'^get/(?P<album_id>\d+)/$', 'album.views.album'), 
    url(r'^like/(?P<album_id>\d+)/$', 'album.views.like_album'), 
""" 
) 

，這解決了它：

urlpatterns = patterns('', 
    url(r'^all/$', 'album.views.albums'), 
) 
""" 
    url(r'^create/$', 'album.views.create'), 
    url(r'^get/(?P<album_id>\d+)/$', 'album.views.album'), 
    url(r'^like/(?P<album_id>\d+)/$', 'album.views.like_album'), 
"""
