网址中带有：username的路由错误 [英] routing error with :username in url

问题描述

我有一个Rails 3问题。我想让我的用户控制器显示页面具有app.com/people/username url。

I have a Rails 3 question. I want to get my users controller show page to have the app.com/people/username url.

Route

resources :users  
match "/people/:username" => 'users#show', :as => :profile

可以，但是如果用户名以。开头（点）我有一个错误：

It's work, but if username starts with "." (dot) I have an error:

没有路线匹配 /people/.G

和

<%= link_to current_user.username, profile_path(current_user.username) %>

引发例外：

没有路由匹配{：controller => users，：action => show，：username =>。G}

对不起

推荐答案

我不认为以开头。。您可以执行以下操作

I don't think starting with . is supported by default in rails routes. You can do something like

match "/people/:username" => 'users#show', :as => :profile, :username => /[\.a-zA-Z0-9_]+/

上述正则表达式将匹配。，az，AZ，0-9和_ 作为用户名的有效字符。

The above regex will match ., a-z, A-Z, 0-9 and _ as valid characters for the username.
