我可以使用Django的身份验证系统的自定义模型吗?

I wrote a custom backend for my application to process logins in a sort-of unique way, as I have specific needs for this project. Here's my backend:

我为我的应用程序编写了一个自定义后端，以某种独特的方式处理登录，因为我对这个项目有特定的需求。这是我的后端:

from my.project.models import User 
from hashlib import sha512

class MyBackend:

    def authenticate(self, email_address=None, password=None):
        print "Trying to auth: " + email_address

        try: 
            user = User.objects.get(email_address=email_address)
            password = sha512(password + user.password_salt).hexdigest()

            if user.password != password:
                return None
            else:
                return user
        except User.DoesNotExist:
            return None

    def get_user(self, user_id):
        try:
            return User.objects.get(pk=user_id)
        except User.DoesNotExist:
            return None

Here's my User class:

这是我的用户类:

class User(models.Model):
    email_address = models.EmailAddressField()
    password = models.CharField(max_length=128)
    password_salt = models.CharField(max_length=128)

It's pretty simple, but I've already built the rest of my models around this 'User' class.

它非常简单，但是我已经围绕这个“User”类构建了我的其余模型。

Is there a way to make this work so as to have the best of both worlds, or should I ditch this approach and just use Django's built-in model for users?

是否有一种方法可以使这一功能发挥到极致，或者我应该抛弃这种方法，只对用户使用Django的内置模型?

Extending the user can best be done by using user profiles. Define a user profile-model and at the bottom, add something like this:

扩展用户可以通过使用用户配置文件来完成。定义一个用户概要文件模型，在底部添加如下内容:

User.profile = property(lambda u: Profile.objects.get_or_create(user=u)[0])

I think this approach might be better than replacing the User-model

我认为这种方法可能比替换用户模型更好
