Ruby on rails 如何在URL中获取日期

我的路由器.rb

resources :post_categories, :path => '', :only => [:show] do
    resources :posts, :path => '', :only => [:show]
end

我能得到你需要的

/category/id
/category

如何获取此URL

/category/2015/11/08/id

我想做这样的事

  resources :post_categories, path: '', only: :show do
    resources :posts, path: '/:year/:month/:day', only: :show, constraints: { year: /\d{4}/, month: /\d{2}/, day: /\d{2}/ }
  end

但是我不知道如何让员工

你考虑过把日期作为一个查询放在url中吗

/category/：id？date=2015-11-08
