一、ITIL即IT基础架构库(Information Technology Infrastructure Library, ITIL，信息技术基础架构库)由英国政府部门CCTA(Central Computing and Telecommunications Agency)在20世纪80年代末制订，现由英国商务部OGC(Office of Government Commerce)负责管理，主要适用于IT服务管理（ITSM）。ITIL为企业的IT服务管理实践提供了一个客观、严谨、可量化的标准和规范。

二、Django用户自定义认证

1、创建models.py

from django.db import models

import hashlib

#自己的后台数据库表.account

class Account(models.Model):

username = models.CharField(u"用户名",blank=True,max_length=32)

password = models.CharField(u"密码",blank=True,max_length=50)

domain = models.CharField(u"可操作域名",blank=True,max_length=256,help_text='填写多个域名，以,号分隔')

is_active = models.IntegerField(u"is_active",blank=True)

phone = models.CharField(u"电话",max_length=50)

mail = models.CharField(u"邮箱",max_length=50)

def __unicode__(self):

return self.username

def is_authenticated(self):

return True

def hashed_password(self, password=None):

if not password:

return self.password

else:

return hashlib.md5(password).hexdigest()

def check_password(self, password):

if self.hashed_password(password) == self.password:

#if password == self.password:

return True

return False

class Meta:

db_table = "account"

2、auth.py

rom django.contrib.auth.models import User

from myauth.models import Account

class MyCustomBackend:

def authenticate(self, username=None, password=None):

try:

user = Account.objects.get(username=username)

except Account.DoesNotExist:

return None

else:

if user.check_password(password):

try:

django_user = User.objects.get(username=user.username)

except User.DoesNotExist:

#当在django中找不到此用户，便创建这个用户

django_user = User(username=user.username,password=user.password)

django_user.is_staff = True

django_user.save()

return django_user

else:

return None

def get_user(self, user_id):

try:

return User.objects.get(pk=user_id)

except User.DoesNotExist:

return None

3、把自己创建的表也加入到进去，admin.py

from myauth.models import Account

from django.contrib import admin

admin.site.register(Account)

4、在settings.py中添加认证：

AUTHENTICATION_BACKENDS = (

'myauth.auth.MyCustomBackend' ,

)
