Rails 3：子域路由
我正在尝试从rails 2.3.x（带有 subdomain_routes 插件）转换一些子域路由，如下所示：
map.subdomain :biz do |biz|
biz.resources :users
biz.resources :projects
biz.root :controller => 'home'
end
使用这些路由，我得到如下网址：
http://biz.example.com/users # :controller => 'biz/users', :action => 'index', :subdomain => 'biz'
使用rails3，没有 subdomain_routes 并且我无法创建相同类型的路线（即使我读过这是可能的）。尝试过这个：
scope :module => :biz, :as => :biz do
constraints(:subdomain => 'biz') do
resources :users
resources :projects
root :to => 'Biz::HomeController#index'
end
end
但是在控制台上尝试时，我没有得到子域，因此： app.biz_users_url # http://www.example.com/users 但不是 http://biz.example.com/users
我也阅读/观看了这些资源，但没有解决我的具体问题：
http://railscasts.com/episodes/221-subdomains-in-rails- 3 http://yehudakatz.com/2009/12 /26/the-rails-3-router-rack-it-up
有什么建议吗？提前致谢；）

I'm trying to convert some subdomain routes from rails 2.3.x (with subdomain_routes plugin) like these:
map.subdomain :biz do |biz|
biz.resources :users
biz.resources :projects
biz.root :controller => 'home'
end
with those routes, i got urls like this:
http://biz.example.com/users # :controller => 'biz/users', :action => 'index', :subdomain => 'biz'
with rails3, there isn't subdomain_routes and I can't create the same kind of routes (even if I've read that is possible). Tried with this:
scope :module => :biz, :as => :biz do
constraints(:subdomain => 'biz') do
resources :users
resources :projects
root :to => 'Biz::HomeController#index'
end
end
but when trying on console, I don't get subdomain, so for:
app.biz_users_url # http://www.example.com/users but not http://biz.example.com/users
I've also read/watched these resources, but there's no solution to my specific problem:
http://railscasts.com/episodes/221-subdomains-in-rails-3

any suggestions? thanks in advance ;)

上面的路由是正确的，主要问题是它们不能与 locahost 一起使用。使用 http://lvh.me （指向 127.0.0.1 的虚拟域）作为假域解决
the above routes are correct, tha main problem was that they doesn't work with locahost. solved using http://lvh.me (a virtual domain that points to 127.0.0.1) as fake domain
您可以通过以下调用获取带有子域的 URL app.biz_users_url(subdomain: 'biz')
You can get the URL with the subdomain making the following call app.biz_users_url(subdomain: 'biz')
