lI'm trying to develop an app to manage media files I have a folder with 
pictures, audio and video files I'm using Dir.glob to list the directory in 
my controller and in my views i'm 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's 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 %>
