Ruby on Rails目录浏览器

Question

I'm trying to write a simple RoR app that lists all directories in a specific path then allows me to click that file or directory to either open the file or open the directory. I'm using the following code which works to list the directories but I can't figure out how to open the file or directory from here. When clicking the directory I get a "No route matches [GET] "/selected file" error.

controller
    @file = Dir.foreach ("/specifiedpath/")

view
<% @file.each do |file| %> 
    <tr>
        <td><%= link_to file, file %></td>
    </tr>
<% end %> 

Any help would be appreciated!

You need something in your routes.rb that looks like this:

get '/browse/*path' => 'browse#show', as: :browse

In your browse_controller , you'll want a show action that does something like:

class BrowseController < ApplicationController

  def show
    @path = params[:path] || '/some/default'
    @files = Dir.foreach(path)
  end

Finally, in your browse/show.html.haml (I prefer HAML, sorry) view, something like:

- @files.each do |file|
  %tr
    %td= link_to file, browse_path(File.join(@path, file))

(Pardon me if it all doesn't work outright—haven't time to fully test a fleshed out solution right now—but I can delve into it a little more if you have trouble getting it to work yourself.)
