rails 3 在route中重定向-优快云博客

本文介绍了一种使用Rails 3 Route Globbing技术处理未定义路由的方法。通过配置特定的路由规则，可以将所有不存在的URL指向一个统一的错误控制器，并提供自定义的404页面。

Yourapp::Application.routes.draw do
  #Last route in routes.rb
  match '*a', :to => 'errors#routing'
end
NOTE: The "a" is actually a parameter in the Rails 3 Route Globbing technique. For example, if your url was /this-url-does-not-exist, then params[:a] equals "/this-url-does-not-exist". So be as creative as you'd like handling that rogue route.

app/controllers/errors_controller.rb

Here, I handle my routing errors. I leverage previous 404 handling code from my original ApplicationController mentioned above. So, my errors_controller.rb looks like this:

class ErrorsController < ApplicationController
  def routing
    render_404
  end
end
However, feel free to modify to fit your individual needs. Everyone's situation will be slightly different. For example, if you're not going to reuse your 404 error handling logic, then here's the full ErrorsController without inheritance:

class ErrorsController < ApplicationController
  def routing
   render :file => "#{Rails.root}/public/404.html", :status => 404, :layout => false
  end
end


match "/posts/github" => redirect("http://github.com/rails.atom")
match '*path' => redirect('/')   unless Rails.env.development?

match ':graphs/:id(/:method)' => 'pages#something'
