Ruby on Rails route for wildcard subdomains to a controller/action

Question

I dynamically create URLs of the form username.users.example.com:

bob.users.example.com
tim.users.example.com
scott.users.example.com

Answer 1

I think, you just need to do the following :

create a class Subdomain in lib :

  class Subdomain  
    def self.matches?(request)  
      request.subdomain.present? && request.host.include?('.users')
    end  
  end

and in your routes :

constraints Subdomain do
  match '', to: 'my_controller#show'
end
