我想实现具有以下能力的blog \news应用程序:

1. 显示root的所有帖子: example.com/
2. 显示所有回答某些年份的帖子: example.com/2012/
3. 显示所有回答某些年份和月份的帖子: example.com/2012/07/
4. 按日期和slug显示一些帖子: example.com/2012/07/slug-of-the-post

match "/posts" => redirect("/")
match "/posts/" => redirect("/")

# Get /posts/2012/?page=1
match "/posts/:year", :to => "posts#index",
  :constraints => { :year => /\d{4}/ }

# Get /posts/2012/07/?page=1
match "/posts/:year/:month", :to => "posts#index",
  :constraints => { :year => /\d{4}/, :month => /\d{1,2}/ }

# Get /posts/2012/07/slug-of-the-post
match "/posts/:year/:month/:slug", :to => "posts#show", :as => :post,
  :constraints => { :year => /\d{4}/, :month => …
