This is based on Phallstrom's excellent Ruby library to provide server side functionality for elFinder: https://github.com/phallstrom/el_finder

This version provides a Rails backend for elFinder that uses an FTP server as its file storage, rather than the local filesystem. elFinder is an open-source file manager for web, written in JavaScript using jQuery UI.

This version provides a partial implementation of the 2.x API (the portions that can be used with FTP).

Operations such as archive, copy, duplicate, etc are not possible using FTP. Needless to say, thumbnails are also not supported.

Net::FTP is used to communicate with the FTP server.

• Install elFinder (http://elrte.org/redmine/projects/elfinder/wiki/Install_EN)
• Do whatever is necessary for your Ruby framework to tie it together.

• Add gem 'el_finder_ftp' to Gemfile

• % bundle install

• Switch to using jQuery instead of Prototype

• Add the following action to a controller of your choosing.

• Use ElFinderFtp::Action and el_finder_ftp, which handles most of the boilerplate for an ElFinderFtp action:

  require 'el_finder_ftp/action'

  class MyController < ApplicationController
    include ElFinderFtp::Action

    el_finder_ftp(:action_name) do
      {
        :server => { host: 'my.ftp.com', username: 'username', password: 'password' },
        :url: "/ftp",
        :perms => {
           /^(Welcome|README)$/ => {:read => true, :write => false, :rm => false},
           '.' => {:read => true, :write => false, :rm => false}, # '.' is the proper way to specify the home/root directory.
           /^test$/ => {:read => true, :write => true, :rm => false},
           'logo.png' => {:read => true},
           /\.png$/ => {:read => false} # This will cause 'logo.png' to be unreadable.  
                                        # Permissions err on the safe side. Once false, always false.
        },
      }
    end
  end

• Add the appropriate route to config/routes.rb such as:

  match 'ftp' => 'my_controller#action_name'

• Add the following to your layout. The paths may be different depending on where you installed the various js/css files.

  <%= stylesheet_link_tag 'jquery-ui/base/jquery.ui.all', 'elfinder' %>
  <%= javascript_include_tag :defaults, 'elfinder/elfinder.min' %>

• Add the following to the view that will display elFinder:

  <%= javascript_tag do %>
    $().ready(function() { 
      $('#elfinder').elfinder({ 
        url: '/ftp',
        lang: 'en'
      })
    })
  <% end %>
  <div id='elfinder'></div>

• That's it.
