Question

在我的django应用程序中，当我运行服务器时，我收到错误。

来自。导入视图来自django.core.context_processors导入csrf ImportError：没有名为＆＃39; django.core.context_processors＆＃39;

的模块

我的views.py文件是

   from django.views.generic import View
from django.utils import timezone
from django.shortcuts import render, get_object_or_404,render_to_response,redirect
from django.http import HttpResponseRedirect
from django.contrib import auth
from django.contrib.auth import authenticate,login
from django.core.context_processors import csrf
from .forms import UserForm

# Create your views here.

def home(request):
    return render(request, 'fosssite/home.html')

def login(request):
    c={}
    c.update(csrf(request))
    return render_to_response('fosssite/login.html',c)

def UserFormView(request):
    form_class=UserForm
    template_name='fosssite/signup.html'

    if request.method=='GET':
        form=form_class(None)
        return render(request,template_name,{'form':form})


        #validate by forms of django
    if request.method=='POST':
        form=form_class(request.POST)

        if form.is_valid():
            # not saving to database only creating object
            user=form.save(commit=False)
            #normalized data
            username=form.cleaned_data['username']
            password=form.cleaned_data['password']
            #not as plain data
            user.set_password(password)
            user.save() #saved to database

            user=auth.authenticate(username=username,password=password)
            if user is not None:
                auth.login(request,user)
                return HttpResponseRedirect('/')#url in brackets

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

def auth_view(request):
    username=request.POST.get('username', '')
    password=request.POST.get('password', '')
    user=auth.authenticate(username=username,password=password)

    if user is not None:
        auth.login(request,user)
        return HttpResponseRedirect('/profileuser')#url in brackets
    else:
        return HttpResponseRedirect('/invalid')

def profileuser(request):
    return render_to_response('fosssite/profileuser.html',{'fullname':request.user.username})

def logout(request):
    auth.logout(request)
    pass

def edit_user_profile(request):
    pass

def invalid_login(request):
    return render_to_response('fosssite/invalid_login.html')

Answer 1

尝试将此导入更改为from django.template.context_processors import csrf。您当前的导入似乎已折旧（通过https://docs.djangoproject.com/en/1.9/releases/1.8/#django-core-context-processors）

Answer 2

首先，删除导致错误的无效导入

from django.core.context_processors import csrf

接下来，render_to_response快捷方式已过时，您应该使用render代替。例如：

from django.shortcuts import render

def login(request):
    c={}
    return render(request, 'fosssite/login.html', c)

render快捷方式使用RequestContext自动，因此您无需手动管理视图中的csrf令牌。

在views.py
