我正在创建仅需要电子邮件和密码的注册,登录和注销。当我使用user = models.OneToOneField(User,on_delete = models.CASCADE)时,我也遇到了错误,因为它也需要用户名。如何仅从用户那里获取电子邮件和密码并将其保存到用户?

您可以使用
AUTHENTICATION_BACKENDS = ('path_to_file.EmailAuthBackend', 'django.contrib.auth.backends.ModelBackend',)
在设置中
和后端文件:
from django.contrib.auth.backends import ModelBackend
from django.contrib.auth import get_user_model
from django.contrib.auth.hashers import check_password
from django.contrib.auth.models import User
class EmailAuthBackend(object):
@staticmethod
def authenticate(self, username="", password="", **kwargs):
user_model = get_user_model()
try:
user = user_model.objects.get(email=username)
if check_password(password, user.password):
return user
else:
return None
except user_model.DoesNotExist:
return None
@staticmethod
def get_user(user_id):
try:
return User.objects.get(pk=user_id)
except User.DoesNotExist:
return None
并在模型中添加唯一的电子邮件规则
from django.contrib.auth.models import User
User._meta.get_field('email')._unique = True
