在 Ruby on Rails 中使用破折号 `-` 而不是下划线 `_` 的路由

问题描述

我希望我的网址使用破折号 - 而不是下划线 _ 作为单词分隔符.例如 controller/my-action 而不是 controller/my_action.

I want my urls to use dash - instead of underscore _ as word separators. For example controller/my-action instead of controller/my_action.

我对两件事感到惊讶:

1. Google 等继续区分它们.
2. Ruby on Rails 没有一个简单的全局配置参数来在路由中将 - 映射到 _.或者是吗?

1. Google et al. continue to distinguish them.
2. That Ruby on Rails doesn't have a simple, global configuration parameter to map - to _ in the routing. Or does it?

我的最佳解决方案是使用 :as 或命名路由.

The best solution I've is to use :as or a named route.

我的想法是修改 Rails 路由以检查全局配置并将 - 更改为 _，然后再分派到控制器操作.

My idea is to modify the Rails routing to check for that global config and change - to _ before dispatching to a controller action.

有更好的方法吗?

推荐答案

使用 Rails 3 及更高版本，您可以这样做:

With Rails 3 and later you can do like this:

resources :user_bundles, :path => '/user-bundles'

另一种选择是通过初始化程序修改 Rails.不过我不建议这样做，因为它可能会在未来的版本中崩溃(在 Rails 5 中不起作用).

Another option is to modify Rails, via an initializer.I don't recommend this though, since it may break in future versions (edit: doesn't work in Rails 5).

如上所示使用 :path 更好.

Using :path as shown above is better.

# Using private APIs is not recommended and may break in future Rails versions.
# https://github.com/rails/rails/blob/4-1-stable/actionpack/lib/action_dispatch/routing/mapper.rb#L1012
#
# config/initializers/adjust-route-paths.rb
module ActionDispatch
  module Routing
    class Mapper
      module Resources
        class Resource
          def path
            @path.dasherize
          end
        end
      end
    end
  end
end
