Question

我是Django的新手，并尝试使用带有Django 1.4的django.contrib.auth.views.login为我的网页构建一个简单的登录系统。我有一个包含以下登录表单的基本模板，然后由我网站上的其他模板页面进行扩展：

<form method="post" action="/accounts/login/">
{% csrf_token %}
<p><label for="id_username">Username:</label> <input id="id_username" type="text" name="username" maxlength="30" /></p>
<p><label for="id_password">Password:</label> <input type="password" name="password" id="id_password" /></p>
<input type="submit" value="Log in" />
<input type="hidden" name="next" value="{{ request.get_full_path }}" />
</form>

但是当我尝试登录时，我收到以下消息：

“禁止（403） CSRF验证失败。请求中止。失败的原因： CSRF令牌丢失或不正确。“

来自urls.py的相关摘录：

url(r'^accounts/login/$', 'django.contrib.auth.views.login')

和settings.py:

TEMPLATE_CONTEXT_PROCESSORS = (
'django.core.context_processors.request',
)

.....

INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
'django.contrib.staticfiles',
)
.....
MIDDLEWARE_CLASSES = (
'django.middleware.common.CommonMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
)

有什么建议吗？

简单的登录/注销系统可以找到here

让我简要解释如何通过Django中的用户模型使用标准身份验证：

<强> 应用程序名称/ views.py：

from django.http import HttpResponse
from django.contrib.auth import authenticate, login
from django.contrib.auth.decorators import login_required
from django.template import Context, loader, RequestContext
from django.shortcuts import render_to_response
from django.template import 

@login_required
def stat_info(request):
return render_to_response('stat_info.html',
  {'is_auth':request.user.is_authenticated()},
  context_instance=RequestContext(request))

@login_required
def mainmenu(request):
return render_to_response('mainmenu.html',{},
  context_instance=RequestContext(request))

<强> urls.py：

from django.conf.urls import patterns, include, url
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    url(r'^admin/', include(admin.site.urls)),
    (r'^statinfo/$', 'appname.views.stat_info'),
    (r'^accounts/login/$', 'django.contrib.auth.views.login'),
    (r'^accounts/logout/$', 'django.contrib.auth.views.logout', {'next_page' : '/accounts/login'}),
    (r'^mainmenu/$', 'appname.views.mainmenu')
)

<强> settings.py：

...        
LOGIN_REDIRECT_URL='/mainmenu/'
...

<强> 模板/注册/ login.html的：

{% extends "base.html" %}
{% block content %}
    {% if form.errors %}
    <p>Your username and password didn't match. Please try again.</p>
    {% endif %}
    <form method="post" action="{% url django.contrib.auth.views.login %}">
    {% csrf_token %}
    <table>
        <tr>
            <td>{{ form.username.label_tag }}</td>
            <td>{{ form.username }}</td>
        </tr>
        <tr>
            <td>{{ form.password.label_tag }}</td>
            <td>{{ form.password }}</td>
        </tr>
    </table>
    <input type="submit" value="login" />
    <input type="hidden" name="next" value="{{ next }}" />
    </form>
{% endblock %}

<强> 模板/ base.html文件：

<!DOCTYPE html>

    <ul>
        <li><a href="/">Home</a></li>

        {% if user.is_authenticated %}
            <li><a href="/accounts/logout">Logout</a></li>
        {% else %}
            <li><a href="/accounts/login">Login</a></li>
        {% endif %}
    </ul>
    {% endblock %}
</div>
<div id="content">
    {% block content %}{% endblock %}
</div>
</body>
</html>

<强> 模板/ mainmenu.html：

<!DOCTYPE html>
{% extends "base.html" %}
<html>
<head>
    <title>{% block title %}templates/mainmenu.html{% endblock %}</title>

<div id="content">
    {% block content %}
    Mainmenu
    <a href="/statinfo/">stat info</a>

Answer 2

模型：

类UserProf（models.Model）：

"""
Create  ``RegistrationProfile for User``
"""
user = models.OneToOneField(User)

""" Other fields here """
address1 = models.CharField(max_length=100,blank=True)
address2 = models.CharField(max_length=100,blank=True)
city = models.CharField(max_length=40,blank=True)
country = models.CharField(max_length=40,blank=True)
age = models.IntegerField(blank=True)

的观点：

来自django.contrib.auth import authenticate，login

def user_authenticate（request）：

"""
    check username and password and displays its appr. user_profile page
"""

username = password = ''
if request.POST:
    username = request.POST.get('username')
    password = request.POST.get('Password')

    user = authenticate(username=username, password=password)
    if user is not None:
        if user.is_active:
            login(request,user)
            return HttpResponseRedirect('/profile/')

    else:
        return HttpResponseRedirect('/qioness/connect/')
else:
    return HttpResponseRedirect('/qioness/connect/')

URL（R '^简档/ $'，show_detail），

模板：

          <form action="/qioness/" method="post">
                       <label>

                        <strong class="email-label">Username</strong>

                        <input type="text"  id="Email" name="username">

                        <span class="login_error"></span>

                      </label>

                      <label>
                          <strong class="passwd-label">Password</strong>
                          <input type="password" id="Passwd" name="Password">

                          <span class="login_error">  </span>
                      </label>

                   <input name="Add" type="submit" value="Log" class="Submit_btn" />


                          <label class="remember">
                              <input type="checkbox" value="yes" id="PersistentCookie" name="PersistentCookie">
                              <strong class="remember-label">
                                   Remember Me
