python - ajax 请求在 Django 中查看产生 404

Question

对于我的 ajax 请求，我收到 404

[06/Feb/2015 06:46:27] "POST /contact/ HTTP/1.1" 404 2149

我是 AJAX 新手，但我认为我的逻辑是向 /contact/ url 发送 POST 请求。这会将请求发送到我的 View 中的 contact 函数并打印出一些文本(目前用于测试目的)。我不知道为什么会收到 404 错误。总的来说，我对 Django 和 Web 开发还很陌生。

js:

    function create_post() {
        console.log("create post is working");
        var firstName = document.getElementById("firstname");
        var lastName = document.getElementById("lastname");
        var email = document.getElementById("email");
        var phoneNumber = document.getElementById("phonenumber");
        var message = document.getElementById("message");
        var contactInfo = {
            "first_name": firstName.value,
            "last_name": lastName.value,
            "email": email.value,
            "phone_number": phoneNumber.value,
            "message": message.value
        };

        $.ajax({
            url: "/contact/",
            type: "POST",
            data: contactInfo,
            success: console.log(contactInfo),
            error: console.log("ajax fail")

        });
    };


//    Contact form submit
    var contactForm = document.getElementById("contact-form");
    $(contactForm).on('submit', function(event) {
        event.preventDefault();
        console.log("form submitted");
        create_post();
    });

我猜这可能是我的网址？

home/urls.py:

urlpatterns = patterns('',
    url(r'^$', load_home_content),
    url(r'^contact/$', contact, name="contact"),
)

url.py:

urlpatterns = patterns('',
    url(r'^admin/', include(admin.site.urls)),
    url(r'^$', include('home.urls'), name='home'),
) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

home/views.py:

def contact(request):
    if request == "POST":
        print request.POST
        form = ContactForm(request.POST)
        print form.first_name, form.last_name, form.email, form.phone_number
        if form.is_valid():
            print "form valid"
        else:
            print "form invalid"
    return render(request, 'home/home.html', {'form': ContactForm})

开发人员工具输出:

从包含网址中删除 $ 符号:

url(r'^', include('home.urls'), name='home'),
