使用django-cas (using django-cas)

步骤：

$ git clone <your project> && cd <your project>

$ load your virtualenv for python 

$ hg clone https://bitbucket.org/cpcc/django-cas

$ python setup.py install

$ pip install MySQL-python

if you met problems installing python-dev in ubuntu13, try this approach: 
$ echo "deb http://us.archive.ubuntu.com/ubuntu/ precise-updates main restricted" | sudo tee -a /etc/apt/sources.list.d/precise-updates.list
sudo apt-get update
sudo apt-get install python2.7-dev

$ use django's auth module, even if you are using mongodb. (see: https://docs.djangoproject.com/en/dev/topics/auth/ )setup your local database:

$ create a database named 'm_tv_box_ms'
$ create a table named 'user'
$ 

$ 向 settings.py 中加入以下内容：

# tv_cms/manage.py:
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "tv_cms.settings")

# tv_cms/wsgi.py:
os.environ['DJANGO_SETTINGS_MODULE'] = 'tv_cms.settings'

# tv_cms/tv_cms/wsgi.py
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "tv_cms.settings")

== Installation == (follow https://bitbucket.org/cpcc/django-cas/ ) 

Run `python setup.py install`, or place the `django_cas` directory in your
`PYTHONPATH` directly. (Note: If you're using Python 2.4 or older, you'll need
to install [http://pypi.python.org/pypi/elementtree/ ElementTree] to use
CAS 2.0 functionality.)

Now add it to the middleware and authentication backends in your settings.
Make sure you also have the authentication middleware installed. Here's what
mine looks like:

{{{
MIDDLEWARE_CLASSES = (
'django.middleware.common.CommonMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django_cas.middleware.CASMiddleware',
'django.middleware.doc.XViewMiddleware',
)

AUTHENTICATION_BACKENDS = (
'django.contrib.auth.backends.ModelBackend',
'django_cas.backends.CASBackend',
)
}}}

Set the following required setting in `settings.py`:

* `CAS_SERVER_URL`: This is the only setting you must explicitly define.
Set it to the base URL of your CAS source (e.g.
http://sso.some.edu/cas/).

your settings.py:
