使用用户名自定义 rails url [英] customize rails url with username

问题描述

我想复制 Twitter 个人资料页面并有一个用户名为http://www.my-app.com/username"，虽然我可以在地址栏中手动输入它并导航到个人资料页面，但我无法链接到自定义 URL.

I want to copy the twitter profile page and have a url with a username "http://www.my-app.com/username" and while I can manually type this into the address bar and navigate to the profile page I can't link to the custom URL.

我认为问题出在路线上 - 这是我的 routes.rb 中的代码

I think the problem is in the routes - here's the code in my routes.rb

map.connect '/:username', :controller => 'users', :action => 'show'

此外，我有 Question 和 Answer 模型，我想使用自定义 URL 链接到它们，如下所示:

Also, I have Question and Answer models and I want to link to them with the customized URL like so:

http://www.my-app.com/username/question/answer/2210

推荐答案

您的路线没有任何问题.在定义所有其他路由之后，请记住在最后定义它.我还建议使用 RESTful 路由，并且仅当您想要更好看的 URL 时才使用命名路由.不要使用 map.connect.这里有一些有关 Rails 路由的好读物.

There's nothing wrong with your route. Just remember to define it at the end, after defining all other routes. I would also recommend using RESTful routes and only if you want to have better looking URLs use named routes. Don't use map.connect. Here's some good reading about Rails routes.

这是它的样子:

map.resources :questions, :path_prefix => '/:username' do |question|
  question.resources :answers
end

map.resources :users

map.user '/:username', :controller => 'users', :action => 'show'

只是一个你可以扩展的草稿.

Just a draft you can extend.
