-----------------------------------------------------------------

相关代码如下：

views.py 

from django.shortcuts import render

# Create your views here.
def login(request):
   if request.method == 'POST':
       pass
   elif request.method == 'GET':
       return render(request, 'login.html', {})

------------------------------------------------

urls.py  :

from django.conf.urls import url
from django.contrib import admin
from django.views.generic import TemplateView

import xadmin

from users import views

urlpatterns = [
   url(r'^xadmin/', xadmin.site.urls),
   url('^$', TemplateView.as_view(template_name='index.html'), name='index'),
   url('^login/$', views.login, name='login'),
]

Bobby 老师，

   从错误信息来看:    url('^login/$', views.login, name='login'),

AttributeError: module 'users.views' has no attribute 'login' 

  的确是说，users.views 中没有 login。 以下是 

views.py 内容: 其中明确定义了 login() 函数，以下加粗部分。

from django.shortcuts import render

# Create your views here.
def login(request):
   if request.method == 'POST':
       pass
   elif request.method == 'GET':
       return render(request, 'login.html', {})

  这是我定义的 login() 函数：
  views.py 
  
  from django.shortcuts import render
  
  # Create your views here.
  def login(request):
     if request.method == 'POST':
         pass
     elif request.method == 'GET':
         return render(request, 'login.html', {})
  
  其中明确定义了 login()
