At the beginning of this year I wrote gem 'html_slicer' to simplify HTML
truncation stuff like that.
The general idea was to implement pagination ability for long htmlised articles
and strings, and on the other hand to resize included <iframe>, <img>, <object>
tags, having a width parameter (YouTube objects for example).
Basic setup:
class Article < ActiveRecord::Base
slice :content, :as => :paged, :slice => {:maximum => 300, :text_break =>
"..."}, :resize => {:width => 300}
end
Try it.
