在route.rb中的Rails访问请求以获取动态路由 [英] Rails access request in routes.rb for dynamic routes

问题描述

我们的网站应允许显示与给定URL相关的不同内容..诸如wordpress中的多站点，其中我们有一个安装并根据URL提供内容。

Our websites should allow to show different contents related to the given url .. something like a multisite in wordpress where we have one installation and serve the content according to the url.

因为必须以正确的语言显示路线，所以我想使用动态路线方法来投放正确的内容。现在的问题是，如果动态的话，我找不到在route.rb中提供正确路线的方法。

as it is necessary to have the routes in the correct language I want to use a "dynamic route" approach to serve the right content. My problem is now that I dont find a way how to serve the proper routes in routes.rb if they are dynamic.

如何访问或传递 请求对象到routes.rb文件内的任何方法中

How can I "access" or "pass" the request object into any method inside the routes.rb file

fe像这样

  Frontend::Application.routes.draw do
    DynamicRouter.load request
  end

app / models / dynamic_router .rb

app/models/dynamic_router.rb

class DynamicRouter
  def self.load request
    current_site = Site.find_by_host(request.host)
    Frontend::Application.routes.draw do
      current_site.routes do |route|
        get "#{route.match}", to: "#{route.to}"
      end
    end
  end
end

此操作无效，因为在route.rb中未定义请求。

this doesnt work because request is undefined in routes.rb

推荐答案

一种可行的解决方案是在route.rb上创建默认规则，并添加一个可以根据域转换路径的机架中间件

A possible soluction is to create the default rules on routes.rb and add a rack middleware that can transform a path according to the domain

# routes.rb
get '/category/:id', :to => 'categories#show'

在中间件中，您可以将 categoria /：id之类的路径转换为如果应用程序访问路由器层之前域与 .es匹配，则为 / category /：id。

In the middleware you can transform a path like 'categoria/:id' to '/category/:id' if the domain matches '.es', before the application hits the router layer.
