This is a simple plugin extracted from Mephisto for creating permalinks from attributes.

  class Article < ActiveRecord::Base
    has_permalink :title
  end

This will escape the title, making it fit to use in a URL in the after_validation callback.

Use PermalinkFu.escape to escape a string manually if you like.

This is a very concise plugin with little-to-no documentation. It'll get the job done, but you're flying blind for the most part.

I wasn't able to update all the existing objects I had, after adding the plugin. I had to change a line in permalink_fu.rb in order to fix an invalid SQL condition that was sent to the DB. Something like : "WHERE (permalink='', 'permalink-title-value' AND ID!=1)

Line 74
```
#base    = send(&quot;#{self.class.permalink_field}=&quot;, send(self.class.permalink_field)[0..limit - 1])
base    = send(self.class.permalink_field)[0..limit - 1]
```
I also used the howto tutorial for this plugin written by Eadz here : http://www.seoonrails.com/even-better-looking-urls-with-permalink_fu

Most of the plugins including this one assumes that everyone knows everything. So they contain very little or no information. For example, permalink_fu does not have instructions on how to use it for an existing project (where records already exist). very disappointing.
