Question

如果子域名不是www＆＃39;，我想将请求路由到特殊控制器。

www.example.com    // home#index
section1.example.com // section#index
section1.example.com/name123  // section#name 
section9.example.com // section#index

routes.rb

root 'home#index'

如何强制请求使用具有上述条件的节控制器？

Answer 1

#config/routes.rb
scope constraints: Section do                 #-> only subdomain routes (non WWW)
   resources :section, path: "", only: :show  #-> http://sectionx.url.com/:id
end
root "home#index" #-> should be last so that above routes are parsed first


#lib/section.rb
module Section

    def initializer(router)
        @router = router
    end

    def self.matches?(request)
        Section.exists?(request.subdomain) if request.subdomain.present? && request.subdomain != "www"
    end

end
