CMDB 知识点

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' ,
)
