【问题描述】：

我已经为我的网站安装了 django-facebook-4.0.8。该软件包已成功安装，但会出现不同类型的错误。请帮忙！

我正在使用 AUTH_PROFILE_MODULE = 'django_facebook.FacebookProfile'。

将用户注册为 AUTH 用户，但未在 django_facebook_facebookprofile 表中注册。注册后，'AnonymousUser' 对象没有属性'backend'

这是我的回溯：

标签： python django facebook authentication django-facebook

【解决方案1】：

基本上你在打电话

self.login(request, user)

无需调用

authenticate(username=user, password=pwd)

第一

当你调用 authenticate 时，django 会在用户身上设置 backend 属性，注意要使用哪个后端，更多详细信息请参见此处https://docs.djangoproject.com/en/dev/topics/auth/#django.contrib.auth.authenticate
