在Django中出现此错误“ login（）缺少1个必需的位置参数：'user'”

Question

I am a new Django user and I just created a registration and login system for my website in Django 1.11. I am struck when I go to login section of my website. I get the error as mentioned "login() missing 1 required positional argument: 'user'" and I can't figure out what's wrong with the login function and the variable 'user'. Kindly help me. Thanks in advance. Here is my code:

urls.py:

from django.conf.urls import url
from . import views
from django.contrib.auth import login


app_name='one'

urlpatterns = [
    url(r'^games$',views.games,name='games'),
    url(r'^others$',views.others,name='others'),
    url(r'^about$',views.about,name='about'),
    url(r'^upload$',views.UploadFile.as_view(),name='upload'),
    url(r'^register$',views.UserFormView.as_view(),name='register'),
    url(r'^login/$', login, name='login'),

]

views.py:

from django.shortcuts import render,redirect
from django.contrib.auth import authenticate, login
from django.views.generic.edit import CreateView
from .models import file
from django.views.generic import View
from .forms import user_form
class UserFormView(View):
    form_class = user_form
    template_name = 'one/register_form.html'

    def get (self,request):
        form = self.form_class(None)
        return render(request,self.template_name,{'form':form})

    def post (self,request):
        form = self.form_class(request.POST)
        if form.is_valid():
            user = form.save(commit = False)
            username= form.cleaned_data['username']
            password= form.cleaned_data['password']
            user.set_password(password)
            user.save()

            user= authenticate(username=username, password=password)

            if user is not None:

                if user.is_active:
                    login(request, user)
                    redirect('one:profile')

        return render(request,self.template_name,{'form':form})

You've got the import wrong. You need to import the login view:

from django.contrib.auth.views import login

At the moment you have imported the login function that actually logs the user in.

The login view you are using is deprecated in Django 1.11. You can switch to the new class-based LoginView :

from django.contrib.auth.views import LoginView

url(r'^login/$', LoginView.as_view(), name='login'),
