如何路由/foo到/public/foo.htmlRails中的显示？

我有一个Rails 3.0应用程序(工作在3.2升级),每当有人请求一个不存在的模板时,它会在生产中产生500错误.例如,mysite.com/blog_posts/532将ID为532的帖子作为HTML发送回来没有问题,但如果由于某种原因请求mysite.com/blog_posts/532.txt,该应用程序会引发500 ActionView :: MissingTemplate错误.

这不应该发生,因为模板首先不应该存在.它应该更恰当地是404错误,或者只是显示HTML模板.

如何让应用程序显示所有缺失模板错误的404错误,或显示默认的HTML模板而不是500？
