Django 身份验证失败，出现 403，没有详细消息

Question

我把一些非常简单的东西放在一起。我有一个像这样的小表格:

<form id="loginForm" action>
    <input name="email_address" type="text" placeholder="Email">
    <input name="password" type="password">
    <a id="loginButton">Login</a>
</form>

我的 JavaScript 执行以下操作:

$("#loginButton").click(function(){
    $.post("/login/",$("#loginForm").serialize(), function(data) {
        console.log("login.");
    });
});

我编写了一个自定义的 Django 身份验证后端:

from my.custom.project.models import User

class MyBackend:

    def authenticate(self, email_address=None, password=None):
        print "Trying to auth"
        try:
            return User.objects.get(email_address=email_address, password=password)
        except User.DoesNotExist:
            return None

    def get_user(self, user_id):
        try:
            return User.objects.get(pk=user_id)
        except User.DoesNotExist:
            return None

我在我的 settings.py 中配置了这个，如下所示:

AUTHENTICATION_BACKENDS = (
    "my.custom.project.auth.MyBackend",
)

在我对 /login/ 路径的实际 View 中，这是我所拥有的:

from django.contrib import auth

def login(request):
    print "Trying to auth..."
    email_address = request.POST['email_address']
    password = request.POST['password']

    user = auth.authenticate(email_address=email_address, password=password)

    if user != None:
        auth.login(request, user)

    direct_to_template(request, "my/login/template.json")

这是我的网址映射:

from django.conf.urls.defaults import * 
from django.contrib import admin
from django.contrib.staticfiles.urls import staticfiles_urlpatterns

admin.autodiscover()

urlpatterns = staticfiles_urlpatterns

urlpatterns += patterns('',
    (r'^admin/', include(admin.site.urls)),
    (r'^admin/doc', include('django.contrib.admindocs.urls')),
)

urlpatterns += patterns('my.project.views',
    (r'^$', 'root'),
    (r'^login/?$', 'login'),
    (r'^logout/?$', 'logout'),
)

谁能看出我在这里做错了什么？我在 Django 服务器输出中得到的是:

[16/Sep/2011 20:17:47] "POST /login/ HTTP/1.1" 403 2326

我是在吃疯狂的药吗？我忽略了什么？

都是因为Django内置的CSRF系统:https://docs.djangoproject.com/en/dev/ref/contrib/csrf/
