ruby 通过排除路径文件中定义的路由来检查是否在列出的路由中定义了传入的URL的约束。

class OldRoutesConstraint
  def self.matches?(request)
    # TO-DO: add a check to make sure this code block runs only if no other url matches.
    path = {}
    begin
      _routes = Bangthetable::Application.routes
      _routes.disable_clear_and_finalize = true
      _routes.clear!
      _routes.draw do
        # here you can add any route you want
        # and there will only be routes that are listed below in routes.
        get "/documents/show/:id", :to => "sessions#new"
      end
      ActiveSupport.on_load(:action_controller) { _routes.finalize! }
      path = (Rails.application.routes.recognize_path(request.env["PATH_INFO"], :method => request.env["REQUEST_METHOD"].to_sym) rescue {}) || {}
    ensure
      _routes.disable_clear_and_finalize = false
      Bangthetable::Application.routes_reloader.paths.each{ |path| load(path) }
      # this is where we are reloading the original v2 routes.
      # do not remove this piece of code. Coz from next requests, app will fail.
    end
    Bangthetable::Application.routes_reloader.paths.each{ |path| load(path) }

    return path.has_key?(:controller)
  end
end
