Rails - Jul 2006 - splitting a paragraph into words and spaces

I''m using this:

<% words = article.content.split(/ /) %>
<%= words[0..20] %>

to (ostensibly) split a paragraph into component words, with spaces in 
between, then print to html only the first 20 items, words and spaces. I 
got this (split(/ /)) from the online pickaxe book at 
http://rubycentral.com/book/ref_c_string.html#String.split . The problem 
is, the resulting array seems to contain no spaces, only words, and 
what''s being printed to html is onehugewordthatlookslikethis.

Am I doing something wrong?

try this...

<% words = article.content.split(/ /) %>
<%= words[0..20].join '' '' %>

This will join the first 20 elements with spaces in between. When you split,
it removes the text which you split on.
