Giving a directory listing [RoR]

[ppknight]

I'm trying to display a directory listing, my idea was to populate an array with a list of files, and then display this array. (using the array would also allow me to access the filenames/path's at a later date) This is my current effort, can anyone suggest what the problem is?

class MyTestController < ApplicationController

def dirlisting(dirname)
thelisting=[]
Dir[dirname].each do |f|
thelisting.push(f)
end
end

render_text (thelisting[1])

end

def index
render_text "Showing available media"
dirlisting("\")
end

end


Thanks in advance,
Paul

Problems:

1. You have too many "end"s after "dirlisting"
2. You shouldn't render more than once (render isn't like php's echo)
3. "\" -- the slash needs to be escaped: "\\"

class MyTestController < ApplicationController
  def index
    render_text "Showing available media: " + Dir["\\"].join("\n")
  end
end

Or (better):

controllers/my_test_controller.rb:

class MyTestController < ApplicationController
  def index
    @dirs = Dir["\\"]
  end
end

views/mytest/index.rhtml:

<h1>Available media</h1>
<ul>
  <% for dir in @dirs %>
  <li><%= dir %></li>
  <% end %>
</ul>

Tried using your (better) code, unfortunately this resulted in no errors, but it just showed the 'Available media' heading.
In addition, how would I go about referring to individual files, (I later intend to enable them to be clicked which will open the selected file in an embedded media player).
Would it be simply 'dir[1]' 'dir[2]' etc. ?

Try this code:

class MyTestController < ApplicationController
  def index
    @dirs = Dir["*"]
  end
end

You can create links in the <li>'s to an action that shows the file in a media player:

<%= link_to file, :action => 'show_file_in_player', :id => file %>

Excellent, thank you!
