Question

这是我previous post的延续，我尝试使用一个提交按钮一次提交多个表单。我试图在评论部分解决这个问题，但是我没有成功。

代码似乎没问题，但由于某些原因我收到403错误（ CSRF验证失败。请求已中止）。而且，这是我在命令提示符中得到的：

UserWarning: A {% csrf_token %} was used in a template, but the context did not provide the value. This is usually caused by not using RequestContext. "A {% csrf_token %} was used in a template, but the context "

有人可以帮我弄清问题是什么吗？

Django版本1.9.2
