Question

从Rails 2.3.x + gem subdomain_routes移植时，我遇到了有关Rails 3中子域的路由问题。使用subdomain_routes gem，我可以通过模型轻松映射路径，如下所示：

# config/routes.rb
map.subdomain :model => :site do |site|
  resources :pages
end

这会生成网址助手，例如site_pages_url，可以像这样使用：

# console
@site = Site.find_by_subdomain(“yehuda”)
app.site_pages_url(@site) => http://yehuda.example.com/pages
app.site_page_url(@site, @page) => http://yehuda.example.com/page/routes-rock

在Rails 3中，这大致会转化为：

# config/routes.rb
class SiteSubdomain  
  def self.matches?(request)
    request.subdomain.present? && request.subdomain != 'www' &&
      request.params[:site_id].present?
  end  
end

Blog::Application.routes.draw do
  resources :sites do
    constraints(SiteSubdomain) do
      resources :pages
    end
  end
end

并且重载标准url_for应该基本上像在subdomain_routes中一样工作：

module UrlFor

  def with_subdomain(subdomain)  
    subdomain = (subdomain || "")  
    subdomain += "." unless subdomain.empty?  
    [subdomain, request.domain, request.port_string].join  
  end  

  def url_for(options = nil)  
    if options.kind_of?(Hash) && options.has_key?(:subdomain)  
      options[:host] = with_subdomain(options.delete(:subdomain))  
    end  
    super  
  end

end
ActionDispatch::Routing::UrlFor.send(:include, UrlFor)

但是，网址助手仍然无法生成site_pages_url(@site) #=> http://www.example.com/pages之类的正确网址，而不是预期的http://yehuda.example.com/pages

Answer 1

您已将该课程命名为

SiteSubdomain

这实际上意味着，您的路由应该具有SiteSubdomain而不是Subdomain。修改为

Blog::Application.routes.draw do
  resources :sites do
    constraints(SiteSubdomain) do
      resources :kases
    end
  end
end
