BUG！！！======>django实战,djangoframework : type object 'URLObject' has no attribute 'parse'; u'djangorestframework' is not a registered namespace

    在学习django的过程当中，跟着学习了一篇CSDN内心求法的文章http://blog.csdn.net/thinkinside/article/details/7236807，在这个部分中，需要安装一个django的可选的REST framework，选用了djangoframework。废话不多说，按照步骤会出现这个问题：

AttributeError at /API/cart/items

type object 'URLObject' has no attribute 'parse'

Request Method:
GET
Request URL:
http://127.0.0.1:8000/API/cart/items
Django Version:
.4
Exception Type:
AttributeError
Exception Value:
type object 'URLObject' has no attribute 'parse'
Error during template rendering
In template C:\Python27\lib\site-packages\djangorestframework-0.3.2-py2.7.egg\djangorestframework\templates\renderer.html, error at line 68
type object 'URLObject' has no attribute 'parse'

在网上找了许多解决办法，最后发现原文作者的django版本是基于1.3的，但是现在大部分用的1.4的版本，所以有可能问题是djangoframework的版本不够，重新将其卸载掉，然后下了一个0.4.0的版本，安装以后，旧的问题没有了，又出现了一下的问题：

u'djangorestframwork' is not a registered namespace

我找到了这篇文章

django 1.4 = u'djangorestframwork' is not a registered namespace

也提问了这个问题，重新安装了找到了解决的办法如下:

Login / Logout
Django REST framework includes login and logout views that are needed if you’re using the self-documenting API.

Make sure you include the following in your urlconf:

from django.conf.urls.defaults import patterns, url

urlpatterns = patterns('',
    ...
    url(r'^restframework', include('djangorestframework.urls', namespace='djangorestframework'))
)

方法参考：http://django-rest-framework.readthedocs.org/en/latest/howto/setup.html#setup
