ruby script/plugin install http://chrisfarms.googlecode.com/svn/rails/plugins/acts_as_friendly_param

declare a field in your model that you wish to use for the textual slug with the acts_as_friendly_param macro.

class Post < ActiveRecord::Base
    acts_as_friendly_param :name
end

The result of the Post#name method will be appended to the URL

helpers like:

<%= link_to 'view post', :action => 'show', :id => @post %>

will produce URLs like
/posts/12-monkies-are-coming


Unicode Concerns
================
Although many unicode characters are actually valid in URIs, the rails url helpers are quite strict with their escaping and you can end up with some pretty ugly urls. It is also good for searching if e and é are treated equally.

So.. friendly-param will try to tidy up the following:
- remove any accents from characters
- strip out any plain-crazy characters (Omega, Pi etc)
- convert spaces into hyphens


SEO Concerns
============
To prevent multiple URLs pointing to the same resource, and having a negative effect on search-engine ranking, friendly-url will use 301 redirects on any ambiguous GET requests.

The following behavior should be expected
- trailing slashes will be removed from URLs
- requests for resources using incorrect slugs will be redirected to the the correct URL
- if the routes file is drastically modified then any old URLs that

still work will be redirected to there new equivalent.

There is currently no advanced documentation for this plugin.
