一段时间以来，我一直在尝试使单选按钮显示在Django网站上，并且一直遇到问题。我终于找到了有关手动呈现的表单字段的方法，并且一直在使用它。当我显示它们时，便无法选择它们。如果我能够选择它们，那么我似乎永远无法将这些信息推送到模型中。我尝试了很多不同的方法，但是一直空着。我阅读了这篇文章“ How to Render Django Forms Manually”，希望对您有所帮助，但我不确定我是否理解他在做什么和我在做什么之间的区别。如果这是关于不声明值（这是我所理解的），那么我不知道如何以使按钮显示的方式来实现它。另外，当我能够选择单选按钮和POST时，除了没有将其发布到模型之外，我还在控制台内部收到此错误+----------------+-----------+---------------+-------------+

那是因为我正在使用MaterializeCSS。一旦删除它，它就开始工作。为将来的项目所注意，请勿使用Materialize
