错误 django：属性错误：模块 'django.contrib.auth.views' 没有属性 'Home'

Question

我目前正在尝试实现登录和注销django站点的功能，在虚拟环境中尝试使用命令python manage.py runserver时遇到以下错误。我正在使用django 2.2

我的项目：

realtime
|-core
|-nodejs
|-realtime
|-templates
| |-index.html
|-url.py

我的代码url.py

from django.conf.urls import include, url
from django.contrib import admin
from django.contrib.auth import views 
urlpatterns = [
url(r'Home/$', views.Home, name='Home'),
url(r'^node_api$', views.node_api, name='node_api'),
url(r'^accounts/login/$', auth_views.LoginView.as_view(template_name='myapp/login.html')),
url(r'^login/$', views.LogoutView.as_view(template_name=template_name), name='logout'),
]

core\views.py

from core.models import Comments, User
from django.shortcuts import render
from django.http import HttpResponse, HttpResponseServerError
from django.views.decorators.csrf import csrf_exempt
from django.contrib.sessions.models import Session
from django.contrib.auth.decorators import login_required
import redis
@login_required
def home(request):
comments = Comments.objects.select_related().all()[0:100]
return render(request, 'index.html', locals())
@csrf_exempt
def node_api(request):
try:
#Get User from sessionid
session = Session.objects.get(session_key=request.POST.get('sessionid'))
user_id = session.get_decoded().get('_auth_user_id')
user = User.objects.get(id=user_id)
#Create comment
Comments.objects.create(user=user, text=request.POST.get('comment'))
#Once comment has been created post it to the chat channel
r = redis.StrictRedis(host='localhost', port=6379, db=0)
r.publish('chat', user.username + ': ' + request.POST.get('comment'))
return HttpResponse("Everything worked :)")
except Exception as e:
return HttpResponseServerError(str(e))

在线

url(r'Home/$', views.Home, name='Home'),

视图Home是从模块views加载的，该模块引用该导入：

from django.contrib.auth import views 

由于django.contrib.auth.views没有定义任何类或函数Home，因此会出现错误。

您可能忘记导入应用程序的views模块：

from django.conf.urls import include, url
from django.contrib import admin
from django.contrib.auth import views as auth_views
import core.views as my_app_views
urlpatterns = [
url(r'Home/$', my_app_views.home, name='Home'),
url(r'^node_api$', my_app_views.node_api, name='node_api'),
url(r'^accounts/login/$', auth_views.LoginView.as_view(template_name='myapp/login.html')),
url(r'^login/$', auth_views.LogoutView.as_view(template_name=template_name), name='logout'),
]

请注意，在此新版本中，django.contrib.auth.views的导入名称为auth_views，而您的自定义应用程序的views的导入名称则为my_app_views。这将防止从一个应用程序或另一个调用视图时出现任何混乱
