- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我有一个 Rails 3.0 应用程序(正在升级 3.2),每当有人请求一个不存在的模板时,它都会在生产中给出 500 错误。例如,mysite.com/blog_posts/532 将 ID 为 532 的帖子作为 HTML 发回没有问题,但如果出于某种原因请求 mysite.com/blog_posts/532.txt,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在那里。它更应该是 404 错误,或者可能只是显示 HTML 模板。
如何让应用程序为所有缺失模板错误显示 404 错误,或显示默认 HTML 模板而不是 500?

在您的 applicationController 中,您应该能够从丢失的模板中拯救出来,然后重新引发 404 。
class ApplicationController > ActionController::Base
rescue_from ActionView::MissingTemplate do |exception|
raise ActionController::RoutingError.new('Not Found')
end
end
