Django 1.7多站点用户模型 [英] Django 1.7 multisite User model
问题描述
我想提供一个Django应用程序，它通过单个数据库为不同的用户集提供多个网站。想像一个博客应用程序，它将被不同主题的几个域使用，但是通过向模型添加一个站点字段来使用相同的数据库。
I want to serve a Django application that serves multiple web sites by single database but different user sets. Think like a blog application, it will be used by several domains with different themes, but use same database by adding a site field to models.
我使用 Django的SitesFramework 作为该作业。但是问题是，我不能为不同的站点分离用户模型。我想使用相同的用户模型，每个站点都有一个站点字段和电子邮件字段。
I use Django's SitesFramework for that job. But the problem is, I couldn't separate user models for different sites. I want to use same user model with a site field and email field that unique per site.
我试图扩展 AbstractUser 这样的模型：
I tried to extend AbstractUser model like that:
from django.contrib.auth.models import AbstractUser
from django.contrib.sites.models import Site
from django.contrib.sites.managers import CurrentSiteManager
class Member(AbstractUser):
username = None
site = models.ForeignKey(Site)
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = []
on_site = CurrentSiteManager()
class Meta:
unique_together = ('site', 'email')
但是出现这个错误：'Member.email'必须是唯一的，因为它被命名为'USERNAME_FIELD'。
该问题的最佳做法是什么？
What is the best practice for that issue?
推荐答案
我希望这种方法可以帮助你：
I hope this approach helps to you:
1）撰写用户保存前的名称：
1) Compose username before save:
from django.db import models
from django.contrib.auth.models import AbstractUser
from django.contrib.sites.models import Site
from django.contrib.sites.managers import CurrentSiteManager
class Member(AbstractUser):
site = models.ForeignKey(Site)
on_site = CurrentSiteManager()
USERNAME_FIELD = 'username'
REQUIRED_FIELDS = []
class Meta:
unique_together = ('site', 'email')
from django.db.models.signals import pre_save
from django.dispatch import receiver
@receiver(pre_save, sender=Member)
def compose_username(sender, instance, **kwargs):
instance.username = "{0}__{1}".format( instance.email, instance.site_id )
2）然后覆盖 ModelBackend 在您的自定义auth后端：
2) Then overwrite ModelBackend in your custom auth backend:
from django.contrib.auth.backends import ModelBackend
from django.contrib.auth import get_user_model
class MyModelBackend(ModelBackend):
def authenticate(self, username=None, password=None, **kwargs):
UserModel = get_user_model()
site = kwargs.get('site')
identifier = "{0}__{1}".format( username, site )
try:
user = UserModel.objects.get(username=identifier)
if user.check_password(password):
return user
except UserModel.DoesNotExist:
# Run the default password hasher once to reduce the timing
# difference between an existing and a non-existing user (#20760).
UserModel().set_password(password)
3）记住在设置中设置自定义后端：
3) Remember set your custom backend on settings:
AUTH_USER_MODEL='s1.Member'
SITE_ID = 1
AUTHENTICATION_BACKENDS = ( 'MyApp.MyModule.MyModelBackend',)
4）验证时包括网站：
4) Include site when authenticate:
>>> from s1.models import Member as M
>>> m1 = M()
>>> m1.site_id = 1
>>> m1.email = 'peter@hello.com'
>>> m1.save()
>>> m1.set_password('hi')
>>> m1.save()
>>>
>>> from django.contrib.auth import authenticate, login
>>> u=authenticate(username='peter@hello.com', password='hi', site=1)
>>> u
<Member: peter@hello.com_at_1>
>>>
