ruby-on-rails - 如何在 Rails 4 中进行路由约束

Question

这不起作用：

get '/' => 'addresses#show', :constraints => Subdomain

库/子域.rb：

class Subdomain  
  def self.matches?(request)  
    request.subdomain.present? && request.subdomain != 'www'  
  end  
end

这条路线被忽略了......

谢谢你

Answer 1

Solution:

the specified route has to go before

root to: 'home#index' 

Answer 2

这工作得很好，只有你需要在你的路由中手动添加 subdomain.rb

get '/' => 'addresses#show', :constraints => Subdomain

库/子域.rb：

class Subdomain  
  def self.matches?(request)  
    request.subdomain.present? && request.subdomain != 'www'  
  end  
end

添加routes.rb

  require 'subdomain'

是的，指定的路线必须先走

root to: 'home#index'
