问题
I'm new to Django and trying to build a simple login system for my webpage using django.contrib.auth.views.login with Django 1.4. I have a base template containing the following login form which is then extended by other template pages on my website:
<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>
However when I try to login I get the following message:
"Forbidden (403) CSRF verification failed. Request aborted. Reason given for failure: CSRF token missing or incorrect."
Relevant snippets from urls.py:
url(r'^accounts/login/$', 'django.contrib.auth.views.login')
and 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',
)
Any suggestions?

Let me briefly explain how to use standard auth through the user model in Django:
appname/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))
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')
)
settings.py:
...
LOGIN_REDIRECT_URL='/mainmenu/'
...
templates/registration/login.html:
{% 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 %}
