CSRF验证失败。请求被中止。Python 1.8

下午好

我是django的新手，我正在创建一个登录门户，但我遇到以下错误| CSRF验证失败。请求被中止

我正在使用Django1.8和Python3.4，请帮助我，如果您还需要什么，请告诉我

以下是我的视图.py：

from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth.forms import AuthenticationForm
from django.contrib.auth import login, authenticate, logout
from django.contrib.auth.decorators import login_required
from django.shortcuts import render_to_response
from django.template import RequestContext

def nuevo_usuario(request):
if request.method == 'POST':
    formulario = UserCreationForm(request.POST)
    if formulario.is_valid():
        formulario.save()
        return HttpResponseRedirect('/')
else:
    formulario = UserCreationForm()
return render_to_response('registration/nuevo_usuario.html', {'formulario':formulario}, context_instance = RequestContext(request))

def ingresar(request):
if request.method == 'POST':
    formulario = AuthenticationForm(request.POST)
    if formulario.is_valid():
        usuario = request.POST['username']
        clave = request.POST['password']
        acceso = authenticate(username=usuario, password=clave)
        if acceso is not None:
            if acceso.is_active:
                login(request, acceso)
                return HttpResponseRedirect('/privado')
            else:
                return render_to_response('registration/noactivo.html', context_instance = RequestContext(request))
        else:
            return render_to_response('registration/nousuario.html', context_instance = RequestContext(request))
else:
    formulario = AuthenticationForm()
return render_to_response('registration/ingresar.html', {'formulario':formulario}, context_instance = RequestContext(request))

Este es mi archivo Ingrear.html

{% extends 'base.html' %}
{% block titulo %}Ingresa al sistema{% endblock %}
{% block encabezado %}

{% block content %}
<div class="main">
    <div class="login-form">

        <div class="head">

        </div>
        <form id = 'formulario' method = 'post' action = ''> {% csrf_token %}
            <input type="text" class="text" placeholder="Username" required autofocus>
            <input type="password" placeholder="Password" required>
            <div class="submit">

            </div>
            <p><a href="#">Forgot Password ?</a></p>
        </form>
    </div>

{% endblock %}

]您需要django提供的csrf令牌。。。（包括德扬戈·蒂恩在内）

只需添加csrf标签，什么都不做？谢谢朋友：D你救了我；）
