Question

我在一个多月前成功跟进了这篇博文：http://www.artandlogic.com/blog/2014/04/tutorial-adding-facebooktwittergoogle-authentication-to-a-django-application/

当我创建新环境并重新创建步骤时，我现在在模板渲染过程中遇到导入错误no module named google_auth。

它追溯到这一行：

<a href="{% url 'social:begin' 'google-oauth2' %}?next={{ request.path }}">Login</a>

看起来django没有在社交应用中查找正确的模板处理？关于为什么不再有效的任何想法？

#settings.py
INSTALLED_APPS = (... , 'social.apps.django_app.default', ...)

AUTHENTICATION_BACKENDS = ('social.backends.google.GoogleOAuth2', 'django.contrib.auth.backends.ModelBackend')

TEMPLATE_CONTEXT_PROCESSORS = ('django.contrib.auth.context_processors.auth',
'django.core.context_processors.debug',
'django.core.context_processors.i18n',
'django.core.context_processors.media',
'django.core.context_processors.static',
'django.core.context_processors.tz',
'django.contrib.messages.context_processors.messages',
'social.apps.django_app.context_processors.backends',
'social.apps.django_app.context_processors.login_redirect')

#urls.py
urlpatterns = patterns('', 
url('', include('social.apps.django_app.urls', namespace='social')),
url('', include('django.contrib.auth.urls', namespace='auth')),
url(r'^$', 'app.views.home', name='home'),
)

Answer 1

如果它是你的选择，我建议改用django-allauth。我使用了django-allauth和Python Social Auth，并亲自发现使用django-allauth更容易。所以，如果你有机会，试一试

Answer 2

这是一个难题。

错误，堆栈跟踪的第一行给出了一个线索：＆＃34; Traceback：.... wrapped_callback ....＆＃34; social.apps.django_app.views.auth视图被调用并包含在装饰器psa中。这最终会产生错误，但我认为django.core.handlers.base.get_response隐藏了实际的异常源。我认为重新加注会使堆栈跟踪不完整。

异常可能发生在from social.backends.utils.get_backend中。但是从远处调试很难。

您可以在文件response = wrapped_callback(request, *callback_args, **callback_kwargs)中的django.core.handlers.base行周围注释掉try-catch。加载页面时获得的新堆栈跟踪是什么？
