In Rails, how to see all the "path" and "url" methods added by Rails's routing? (update: using Rails console)
提问by nonopolarity
[update: by not using rake routes, just to understand Rails console a little more]
[更新：不使用rake routes，只是为了多了解 Rails 控制台]
It seems like inside of "rails console" for Rails 3, we can use controller, but in Rails 2.2 or 2.3, we need to use @controller
似乎在 Rails 3 的“rails 控制台”内部，我们可以使用controller，但在 Rails 2.2 或 2.3 中，我们需要使用@controller
And in Rails 3, we can print out all the routes added by Rails routing for a scaffold foo:
而在 Rails 3 中，我们可以打印出所有由 Rails 路由添加到脚手架的路由foo：
ruby-1.9.2-p0 > puts controller.public_methods.grep(/path|url/).grep(/foo/).sort.join("\n")
edit_foo_path
edit_foo_url
foo_path
foo_url
foos_path
foos_url
new_foo_path
new_foo_url
but on Rails 2.3.8, it gives a bunch of formatted_foos_path, etc, and gives nothing for Rails 2.2.2. How to make it print out for Rails 2.3.8 and 2.2.2?
但是在 Rails 2.3.8 上，它给出了一堆formatted_foos_path，等等，而在 Rails 2.2.2 中什么也没有。如何为 Rails 2.3.8 和 2.2.2 打印出来？
Details for Rails 2.3.8:
Rails 2.3.8 的详细信息：
ruby-1.8.7-p302 > puts @controller.public_methods.grep(/path|url/).grep(/foo/).sort.join("\n")
formatted_edit_foo_path

formatted_foo_path
formatted_foo_url
formatted_foos_path

formatted_new_foo_path

helpers = Rails.application.routes.named_routes.helpers
This will get you all the named route methods that were created. Then you can do helpers.map(&:to_s), and whatever regex you want to get your foo versions
这将为您提供所有已创建的命名路由方法。然后你可以做helpers.map(&:to_s)，以及你想要得到你的 foo 版本的任何正则表达式

Well in Rails 4, I use rake routes. Is it that you need?
在 Rails 4 中，我使用rake routes. 是你需要的吗？

or load up localhost_path/rails/info/routesin your browser.
或localhost_path/rails/info/routes在浏览器中加载。
