如何为Rails路由设置特定的子域？

Question

I am trying to setup a subdomain for my site in rails. I followed to rails cast to do this. http://railscasts.com/episodes/221-subdomains-in-rails-3?view=comments

I am having an issue. I want to state that for a specific static subdomain as a secondary homepage.

  constraints(Subdomain) do
    match '/' => 'static_pages#secondary_home'
  end

  root to: 'static_pages#home'

lib/subdomain.rb

class Subdomain
  def self.matches?(request)
    request.subdomain.present? && request.subdomain.eql? "secondaryhome"
  end
end

so now I expect only secondaryhome.lvh.me:3000 to point to my secondary homepage. (lvh.me is and external domain that points to localhost) .However, any subdomain I have (for instance abc.lvh.me:3000) seems to be pointing to the secondary home, while i want it to default to my primary root. What should i do?

We've done the equivalent of this:

#config/routes.rb
constraints({ subdomain: "secondaryhome" }) do
    match '/' => 'static_pages#secondary_home'
end

This sets a route for lvh.me:3000 with constraint { subdomain: "secondaryhome" } - only that should work
