Rails - Apr 2006 - How do I allow downloading pdf & and other files?

I have a library of .pdf and .doc files in the public folder of my Rails 
app.  What''s the best way to configure routes.rb so that I can provide 
links to download these files from my webrick server?

I put my pdf files in a public/pdf folder.  You should be able to just 
download directly: http://localhost:3000/pdf/a-pdf-file.pdf

But if you want the browser to open the files you will need to send a 
mime type.  You can edit webrick''s mime types in htmlutils.rb, but pdf 
and doc are already there in Ruby 1.8.4

If you want to handle everything in rails, try this in the routes.rb

# You may dynamically add additional assests for the
  #  application in these folders under the public folder:
  #  audio, pics, pic2, files (typo upload folder),
  #  pdf and video.  Access them in your post like this:
  #  "Text User Will See that is the Link":/files/filenam.ext
  #  where /files is either /audio, /pics, /pic2, /files, /pdf
  #    /video.
  #  OR for images
  #  !/pics/image.ext!
  #  where ext is png, jpg, and so forth.

  #/audio
  map.audio ''audio/:filename'',
    :controller => ''static'', :action =>
''static_audio''
  #/pics
  map.pics ''pics/:filename'',
    :controller => ''static'', :action =>
''static_images''
  #/pic2
  map.pic2 ''pic2/:filename'',
    :controller => ''static'', :action =>
''static_images2''
  #/files
  map.files ''files/:filename'',
    :controller => ''static'', :action =>
''static_files''
  #/pdf
  map.pdf ''pdf/:filename'',
    :controller => ''static'', :action =>
''static_pdf''
  #/video
  map.video ''video/:filename'',
    :controller => ''static'', :action =>
''static_video''

The static controller looks like this:

class StaticController < ApplicationController
	session :off

  def static_audio
    render_static_item(:audio, params[:filename])
  end

  def static_images
    render_static_item(:pics, params[:filename])
  end

  def static_images2
    render_static_item(:pic2, params[:filename])
  end

  def static_files
    render_static_item(:files, params[:filename])
  end

  def static_pdf
    render_static_item(:pdf, params[:filename])
  end

  def static_video
    render_static_item(:video, params[:filename])
  end

  private

  def render_static_item(type, file, mime = mime_for(file))
    render :text => "Not Found", :status => 404 and return if 
file.split(%r{[\\/]}).include?("..")
    send_file "/#{type}/#{file}", :type => mime, :disposition =>
''inline'', :stream => false
  end

  def mime_for(filename)
    case filename.downcase
    when /\.avi$/
      ''video/x-msvideo''
    when /\.bmp$/
      ''image/bmp''
    when /\.doc$/
      ''application/msword''
    when /\.gif$/
      ''image/gif''
    when /(\.jpg|\.jpe|\.jpeg)$/
      ''image/jpeg''
    when /\.mov$/
      ''video/quicktime''
    when /\.mp3$/
      ''audio/mpeg''
    when /\.png$/
      ''image/png''
    when /\.pdf$/
      ''application/pdf''
    when /\.ppt$/
      ''application/vnd.ms-powerpoint''
    when /(\.rm|\.ram)$/
      ''audio/x-pn-realaudio''
    when /\.swf$/
      ''application/x-shockwave-flash''
    when /(\.tiff|\.tif)$/
      ''image/tiff''
    when /(\.txt|\.asc)$/
      ''text/plain''
    when /\.wav$/
      ''audio/x-wav''
    when /\.zip$/
      ''application/zip''
    else
      ''application/binary''
    end
  end
end
