Django - 使用电子邮件登录 [英] Django - Login with Email
问题描述
我希望 django 通过电子邮件而不是用户名对用户进行身份验证.一种方法可以提供电子邮件值作为用户名值，但我不想要那样.原因是，我有一个 url /profile/，因此我不能有一个 url /profile/abcd@gmail.com/.
I want django to authenticate users via email, not via usernames. One way can be providing email value as username value, but I dont want that. Reason being, I've a url /profile/<username>/, hence I cannot have a url /profile/abcd@gmail.com/.
另一个原因是所有电子邮件都是唯一的，但有时会发生用户名已被占用的情况.因此，我将用户名自动创建为 fullName_ID.
Another reason being that all emails are unique, but it happen sometimes that the username is already being taken. Hence I'm auto-creating the username as fullName_ID.
如何更改让 Django 使用电子邮件进行身份验证?
How can I just change let Django authenticate with email?
这就是我创建用户的方式.
This is how I create a user.
username = `abcd28`
user_email = `abcd@gmail.com`
user = User.objects.create_user(username, user_email, user_pass)
我是这样登录的.
email = request.POST['email']
password = request.POST['password']
username = User.objects.get(email=email.lower()).username
user = authenticate(username=username, password=password)
login(request, user)
除了先获取用户名之外，还有其他登录方式吗?
Is there any other of of login apart from getting the username first?
推荐答案
您应该编写自定义身份验证后端.像这样的东西会起作用:
You should write a custom authentication backend. Something like this will work:
from django.contrib.auth import get_user_model
from django.contrib.auth.backends import ModelBackend
class EmailBackend(ModelBackend):
def authenticate(self, request, username=None, password=None, **kwargs):
UserModel = get_user_model()
try:
user = UserModel.objects.get(email=username)
except UserModel.DoesNotExist:
return None
else:
if user.check_password(password):
return user
return None
然后，在您的设置中将该后端设置为您的身份验证后端:
Then, set that backend as your auth backend in your settings:
AUTHENTICATION_BACKENDS = ['path.to.auth.module.EmailBackend']
已更新.从 ModelBackend 继承，因为它已经实现了像 get_user() 这样的方法.
Updated. Inherit from ModelBackend as it implements methods like get_user() already.
