Limiting Size of Output Field

Hi!

I have a really stupid/simple question. How do you go about limiting the size of a field for the output? For example, I have a field that says...

  <td><%= response.description %></td>

in my list.rhtml file. However, the description, at times, is rather long. How can I limit it to say, 15 or so characters and then just chop off the rest of the text?

Thanks! Mike

truncate(response.description, 15)

   truncate(text, length = 30, truncate_string = "...")

If text is longer than length, text will be truncated to the length of length and the last three characters will be replaced with the truncate_string.

   truncate("Once upon a time in a world far far away", 14)     => Once upon a...

Just be careful about chopping it right in the middle of an html tag...
