Rails：根据域​​名选择不同的root_to路由

Question

我的想法是，如果您访问www.my-website.com，我想显示一个“选择国家/地区”登录页面，并链接到我的各个国家/地区的网站，例如www。 my-website.dk，www.my-website.de等等，等等

我犯了这样的一个的routes.rb：

MyApp::Application.routes.draw do 
    constraints subdomain: /\Awww\b/ do 
    apipie # For API documentation, see initializers/apipie.rb 
    draw :api_v1_v2_v3 
    draw :api 

    constraints ->(request) {request.host =~ /my-website\.com/ } do 
     root to: 'my_website_dot_com#landing_page' # anyone going to http://www.my-website.com/ will get this action 
    end 

    root to: 'my_website#front_page' 

    get 'sitemap', to: 'my_websiteouncle#sitemap' # anyone going to http://www.my-website.de/ or http://www.my-website.dk/ etc. will get this action 
    end 
end 

问题是，我不能有多个root_to与轨4.2因此如何我可以更改routes.rb来实现这种行为吗？

Answer 1

我落得这样做：

constraints ->(request) { request.host =~ /my-website\.com$/ } do 
    get '/' => 'my_website_dot_com#landing_page', locale: :en 
end 

constraints ->(request) { !(request.host =~ /my-website\.com$/) } do 
    root to: 'my_website#front_page' 
end
