在Django中使用python-social-auth重定向回网站时不可用的类型

Question

我正在尝试使用Social-auth-app-django向网站添加社交媒体身份验证.

所以我为最受欢迎的社交媒体网站(Facebook,Twitter,Google +)创建了不同的应用程序,并在那里设置了回调网址.

但是,当我从Facebook重新定向回网站时,我遇到了一个错误:

    Internal Server Error: /oauth/complete/facebook/

以下是我如何配置的摘要social_django:

在settings.py:

INSTALLED_APPS = [
    'social_django',
    ...
]

AUTHENTICATION_BACKENDS = (
    'social_core.backends.google.GoogleOAuth2',
    'social_core.backends.twitter.TwitterOAuth',
    'social_core.backends.facebook.FacebookOAuth2',

    'django.contrib.auth.backends.ModelBackend',
)

SOCIAL_AUTH_FACEBOOK_KEY = 'xxx'
SOCIAL_AUTH_FACEBOOK_SECRET = 'xxx'

...

PIPELINE = {
    'PIPELINE_ENABLED': True,
    'STYLESHEETS': {...},
    'JAVASCRIPT': {...},
    'JS_COMPRESSOR': 'pipeline.compressors.NoopCompressor',
    'COMPILERS': (
        'pipeline.compilers.sass.SASSCompiler',
    )
}

之后,我显然已迁移数据库以创建新表.

请找到的版本以下Django和social_django:

• Django:1.10.5
• social_django:1.2.0

关于使用的管道,我正在使用,django-pipeline但它只是用于编译SASS文件CSS.

什么可能导致此错误？

Answer 1

添加下面的管道settings.py似乎已经解决了问题（来源）：

SOCIAL_AUTH_PIPELINE = (
    'social_core.pipeline.social_auth.social_details',
    'social_core.pipeline.social_auth.social_uid',
    'social_core.pipeline.social_auth.social_user',
    'social_core.pipeline.user.get_username',
    'social_core.pipeline.user.create_user',
    'social_core.pipeline.social_auth.associate_user',
    'social_core.pipeline.social_auth.load_extra_data',
    'social_core.pipeline.user.user_details',
    'social_core.pipeline.social_auth.associate_by_email',
)
