我正在尝试创建一个auth后端,以允许我的用户使用他们的电子邮件地址或他们在Django 1.6中使用自定义用户模型的用户名登录。当我使用用户名登录时,后端工作正常,但由于某种原因,没有电子邮件。有什么我忘记要做的事吗?
from django.conf import settings from django.contrib.auth.models import User class EmailOrUsernameModelBackend(object): """ This is a ModelBacked that allows authentication with either a username or an email address. """ def authenticate(self, username=None, password=None): if '@' in username: kwargs = {'email': username} else: kwargs = {'username': username} try: user = User.objects.get(**kwargs) if user.check_password(password): return user except User.DoesNotExist: return None def get_user(self, username): try: return User.objects.get(pk=username) except User.DoesNotExist: return None
编辑:按照建议,我已从ModelBackend继承并将其安装在我的设置中。在我的设置中,我有这个AUTHENTICATION_BACKENDS =('users.backends','django.contrib.auth.backends.ModelBackend',)并且我将后端更改为这个:
AUTHENTICATION_BACKENDS =
'users.backends','django.contrib.auth.backends.ModelBackend'
from django.conf import settings from django.contrib.auth.models import User from django.contrib.auth.backends import ModelBackend class EmailOrUsernameModelBackend(ModelBackend): """ This is a ModelBacked that allows authentication with either a username or an email address. """ def authenticate(self, username=None, password=None): if '@' in username: kwargs = {'email': username} else: kwargs = {'username': username} try: user = User.objects.get(**kwargs) if user.check_password(password): return user except User.DoesNotExist: return None def get_user(self, username): try: return User.objects.get(pk=username) except User.DoesNotExist: return None
现在我得到一个Module "users" does not define a "backends" attribute/class错误。
Module "users" does not define a "backends" attribute/class
遵循上面给我的建议并进行更改后,AUTHENTICATION_BACKENDS = ['yourapp.yourfile.EmailOrUsernameModelBackend']我遇到了错误Manager isn't available; User has been swapped for 'users.User'。这是由于我使用的是默认用户模型,而不是我自己的自定义模型。这是工作代码。
AUTHENTICATION_BACKENDS = ['yourapp.yourfile.EmailOrUsernameModelBackend']
Manager isn't available; User has been swapped for 'users.User'
from django.conf import settings from django.contrib.auth import get_user_model class EmailOrUsernameModelBackend(object): """ This is a ModelBacked that allows authentication with either a username or an email address. """ def authenticate(self, username=None, password=None): if '@' in username: kwargs = {'email': username} else: kwargs = {'username': username} try: user = get_user_model().objects.get(**kwargs) if user.check_password(password): return user except User.DoesNotExist: return None def get_user(self, username): try: return get_user_model().objects.get(pk=username) except get_user_model().DoesNotExist: return None
