Installation django-rest-Auth 'Nameerror: name 'FacebookLogin' ist nicht definiert'

Question

I http://django-rest-auth.readthedocs.io/en/latest/installation.html#registration-optional gefolgt

Als django-rest-Auth Installation doc sagte, ich installiert django-allauth zuerst, aber url(r'^rest-auth/facebook/$', FacebookLogin.as_view(), name='fb_login'), NameError: name 'FacebookLogin' is not defined kommt, und Ich weiß nicht, wie ich das lösen soll.

Blog/views.py url (r '^ rest-Auth/facebook/$', FacebookLogin.as_view() name = 'fb_login'), Nameerror: name 'FacebookLogin' ist nicht definiert

from rest_framework import status

from rest_framework import generics 
from django.contrib.auth.decorators import login_required 
from allauth.socialaccount.providers.facebook.views import FacebookOAuth2Adapter 
from rest_auth.registration.views import SocialLoginView 


class FacebookLogin(SocialLoginView): 
    adapter_class = FacebookOAuth2Adapter 

Blog/urls.py

    url(r'^rest-auth/facebook/$', FacebookLogin.as_view(), name='fb_login'), 
    ]

Warum dieser Fehler aufgetreten ist?

Was ist meine Schuld?

Danke fürs Lesen.

Answer 1

Fehler ist selbsterklärend, dass FacebookLogin nicht in urls.py definiert ist.

Fehler - Sie verwenden FacebookLogin, aber haben es nicht in urls.py importiert.

Lösung:

Sie haben blog.views im urls.py importiert, so ersetzen FacebookLogin.as_view() mit views.FacebookLogin.as_view()

from django.conf.urls import url, patterns 
from blog import views 
from rest_framework.urlpatterns import format_suffix_patterns 


urlpatterns = [ 
    url(r'^blog/$', views.post_list, name='list'), 
    url(r'^blog/create/$', views.post_create, name='create'), 
    url(r'^blog/(?P<pk>[0-9]+)$', views.post_detail, name='detail'), 
    url(r'^rest-auth/facebook/$', views.FacebookLogin.as_view(), name='fb_login'), 
    ] 

urlpatterns = format_suffix_patterns(urlpatterns) 

OR

importieren Sie die Klasse selbst from blog.views import FacebookLogin.
