当访问管理站点时，'str'对象没有属性'resolve' [英] 'str' object has no attribute 'resolve' when access admin site

问题描述

我不断得到这个错误：
'str'对象没有属性'resolve'

I keep getting this error: 'str' object has no attribute 'resolve'

当尝试访问django管理站点，我可以'找出
为什么。
我的项目中有应用程序拥有自己的admin.py文件。
可以这样吗？
这里是我的urls.py：

when trying to accessing the django admin site and I can't figure out why. I have apps within my project that have their own admin.py files. Could this cause it? here is my 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)), 

...

According to excellent answer posted here: http://redsymbol.net/articles/django-attributeerror-str-object-no-attribute-resolve/

通常有几个错误来源：

1. 您错过了'模式关键字'：

1. You missed 'pattern keyword':

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

应该更改为： / p>

this should be changed to:

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

请注意，在Django 1.8+最好使用正则表达式列表，而不是模式。

Note that in Django 1.8+, it's better to use a list of regexes instead of patterns.

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

您在某些元组中遗漏了逗号，如：

You missed a comma in some tuple, like:

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

你评论了一些url（） -quotes

You commented out some url()s using triple-quotes

你不小心在错误的地方留下一个括号：

You carelessly leave a closing bracket in the wrong place:

(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'),

您将 ROOT_URLCONF 设置为列表

从模式元组迁移到常规列表时忘了删除模式的空的''参数。

When migrating from the pattern tuples to a regular list you forgot to remove the empty '' argument of the pattern.

如果您的代码中没有这种情况，请仔细检查。

Please check carefully if you don't have one of this cases in your code.
