如何在 Ruby on Rails 中创建一个包罗万象的路由?

本文介绍了如何在 Ruby on Rails 中创建一个包罗万象的路由?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我希望所有满足特定约束的请求都转到特定控制器.所以我需要一个包罗万象的路线.我如何在 Rails 中指定它?是这样的吗?

I want to have all requests that satisfy a certain constraint to go to a specific controller. So I need a catch-all route. How do I specify that in Rails? Is it something like this?

match '*', to: 'subdomain_controller#show', constraints: {subdomain: /.+.users/}

那真的能捕获所有可能的路线吗?重要的是，即使有很多嵌套目录，也不能漏掉.

Will that really catch all possible routes? It's important that none slip through even if there are many nested directories.

使用 Ruby on Rails 3.2，但准备升级到 4.0.

UPDATE:'*path' 似乎有效.但是，我遇到的问题是，只要文件存在于我的 public 目录中，Rails 就会呈现它.

UPDATE: '*path' seems to work. However, the issue I'm running into is whenever the file exists in my public directory, Rails renders that instead.

推荐答案

我认为您需要对这种方法稍作调整，但您明白了:

I think you need minor tweaks in this approach but you get the point:

更新:

#RAILS 3 #make this your last route. match '*unmatched_route', :to => 'application#raise_not_found!' #RAILS 4, needs a different syntax in the routes.rb. It does not accept Match anymore. #make this your last route. get '*unmatched_route', :to => 'application#raise_not_found!'

和

class ApplicationController < ActionController::Base ... #called by last route matching unmatched routes. #Raises RoutingError which will be rescued from in the same way as other exceptions. def raise_not_found! raise ActionController::RoutingError.new("No route matches #{params[:unmatched_route]}") end ... end
