Python 为什么我的表单没有保存到管理员数据库？

我正在尝试使用Django为一家在线商店开发一个网站。我想使用Ajax来处理提交后的签出表单视图。提交表格后，我希望它转到：

返回HttpResponseRedirect（反向（str（下一页））+“？address\u added=True”）

，即

但出于某种原因，它不会去那里。而是被重定向到

http://127.0.0.1:8000/checkout/?csrfmiddlewaretoken=W4iXFaxwpdtbZLyVI0ov8Uw7KWOM8Ix5GcOQ4k3Ve65KPkJwPUKyBVcE1IjL3GHa&address=123+Main+Street&address2=&state=MA&country=USA&zipcode=55525&电话=%28877%29+314-0742&账单=on

因此，表单数据也无法保存。我在想是不是因为新版本的Django

我想做的是，在他们提交PlaceOrder按钮后，表单将为None，即消失，然后我将在那里添加一张信用卡表单进行支付。但事实并非如此。这里怎么了？我该怎么做，或者有更好的方法吗

My forms.py：

您是否已将其添加到admin.py文件中，如下所示：

admin.site.register(Name of Model)

@zack turners的回答是正确的。我确实将模型添加到了admin.py文件@andypaling1中。我看到您的代码中有很多错误，但第一个错误是JavaScript。您没有执行event.preventDefault（），并且您没有在请求中包含表单数据（该请求最初不是使用Ajax提交的），您能告诉我正确的方法吗？故意和浪费时间的自我复制：是的，我添加了它，这里还有什么问题吗？您进行了迁移吗是的，我进行了迁移
