在django中获取此错误"login()缺少1个必需的位置参数:'user'"

Question

我是一个新的Django用户,我刚刚在Django 1.11中为我的网站创建了一个注册和登录系统.当我去我网站的登录部分时,我很震惊.我得到的错误如上所述"login()缺少1个必需的位置参数:'user'"我无法弄清楚登录功能和变量'user'有什么问题.请帮助我.提前致谢.这是我的代码:

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})

你输入错了.您需要导入login视图:

from django.contrib.auth.views import login

您已导入login实际记录用户的功能.

login您正在使用的视图在Django 1.11中已弃用.您可以切换到新的基于类LoginView:

from django.contrib.auth.views import LoginView

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