Rails:获取当前请求的控制器和动作 [英] Rails: Get the controller and action of the current request
问题描述
在我的 Rails 应用程序中，我在视图/布局/应用程序中使用 <html id=<%= params[:controller] + "_" + params[:action] %>.html.erb.
In my Rails application, I use <html id=<%= params[:controller] + "_" + params[:action] %> in views/layouts/application.html.erb.
奇怪的是，params[:controller] 和 params[:action] 的值总是滞后 1 个请求 如果它高于打开 标签.
The strange thing is, the values of params[:controller] and params[:action] always lag by 1 request if it is anywhere above the opening <body> tag.
因此，如果我在 users/1 上，但我来自 users/，则上面打开 的值将是控制器:用户"和动作:索引".params[:action] 不应该是show"吗?
So if I'm on users/1, but I came from users/, the values above opening <body> will be controller: "users" and action: "index". Shouldn't params[:action] be "show"?.
然后，如果我刷新页面，它会赶上"并正确地具有控制器:用户"和操作:显示".
Then if I refresh the page, it 'catches up' and correctly has controller: "users" and action: "show".
为什么会这样?如何获取当前请求控制器和操作?在第一次调用 yield 之前，这些参数不会更新吗?
Why is this happening? How can I get the current requests controller and action? Will these params not be updated until the first time yield is called?
