Question

我正在尝试使用Python社交身份验证登录Facebook，但是当我登录并且facebook返回我的网站时，我收到以下消息：

NoReverseMatch at /
Reverse for 'begin' with arguments '(u'facebook',)' and keyword arguments '{}' not found. 1 pattern(s) tried: [u'$login/(?P<backend>[^/]+)/$']

以下是我的观点：

def home(request):
    """Home view, displays login mechanism"""
    if request.user.is_authenticated():
        return redirect('done')
    return render_to_response('home.html', {
        'plus_id': getattr(settings, 'SOCIAL_AUTH_FACEBOOK_KEY', None)
    }, RequestContext(request))


@login_required
def done(request):
    """Login complete view, displays user data"""
    scope = ' '.join(FacebookAuth.DEFAULT_SCOPE)
    return render_to_response('done.html', {
        'user': request.user,
        #'plus_id': getattr(settings, 'SOCIAL_AUTH_GOOGLE_PLUS_KEY', None),
        #'plus_scope': scope
    }, RequestContext(request))

这是整个Traceback：

Answer 1

在https://docs.djangoproject.com/en/1.6/topics/http/shortcuts/#redirect检查Django redirect文档，您的redirect('done')应该引用一个视图名称，该视图名称会查看您未定义的urls.py，因此您尝试重定向用户指向您未注册的URL。

为了使其有效，请尝试将此条目添加到urls.py

...
url(r'^done$', 'reviews.views.done', name='done')
...

使用Python Social Auth / Facebook登录的NoReverseMatch
