如何在Rails 4中做路由约束

Question

这不起作用：

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

LIB / subdomain.rb：

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

这条路线被忽略......

谢谢

Answer 1

<强>解决方案：

指定的路线必须先行

root to: 'home#index' 

Answer 2

只有您需要手动在路线中添加subdomain.rb

，这才能完美运行

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

LIB / subdomain.rb：

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

添加routes.rb

  require 'subdomain'

是的，指定的路线必须先行

root to: 'home#index'
