点击提交账单地址表单会在登录时重定向我，而不是将我重定向到送货地址表单

大佬教程收集整理的这篇文章主要介绍了点击提交账单地址表单会在登录时重定向我，而不是将我重定向到送货地址表单，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

如何解决点击提交账单地址表单会在登录时重定向我，而不是将我重定向到送货地址表单？

我正在学习解释如何使用 django 构建电子商务应用程序的教程。

我有一个购物车部分 [s1]，客户可以在其中查看他/她在购物车中的产品的简历。
在这里，客户可以点击“结帐”按钮，根据教程，

如果客户已登录：

• 应将他/她带到收货地址部分 [s2]，他/她可以在此填写收货地址表单。
  

其他：

• 应引导他/她进入访客身份验证部分 [s2-b] 在那里他/她可以继续作为访客（要求客户提交他/她的电子邮件地址）或登录（要求客户提交用户名和密码），然后到达收货地址表单部分 [s2]。
  

然后，应用应将客户引导至帐单地址表单 [s3]，然后引导至完成部分 [s4]。

我的问题是我无法通过送货地址部分 [s3]，因为当我点击提交按钮时，应用程序会将我重定向到登录表单，（即使我已经登录也会发生这种情况）用户和密码文件都显示“此字段是必需的”消息，当我输入这些信息并按提交按钮时，应用程序将我返回到主页。所以我永远无法到达帐单地址表 [s4]。

我不明白出了什么问题，这是我的代码：
