Building an rails app to manage media files?

Question

I am trying to develop an app to manage media files I have a folder with pictures, audio and video files.

I am using Dir.glob to list the directory in my controller and in my views I am using match with regular expressions to test if the file ends in mp3 jpg mp4 3gp wav etc ... the code I wrote seems to almost work The variable @file is passed on from the controller and here is my view.

Is this a sensible way of trying to do this?

<% if @file.match("mp4") %>
 <video width="320" height="240" controls>
  <source src= <%= @file %> type="video/mp4">
 </video> 
<% elsif @file.match("mp3") %>
 <audio controls preload="auto">
  <source src = <%= @file %> >
 </audio>
<% elsif @file.match("jpg") %>
 <img src= "<%= @file %>">
<% end %>

Do you have a File model? If so then provide either instance or class methods to do the file type testing rather than having code for them in the view. If you don't have a File model then create one (not ActiveRecord based) to manage the logic.
