Pretty Permalinks on Rails

Hot dang it’s so easy! I am using Rails 3, and it’s as easy as adding .parameterize to an attribute.

For example, if you want something like

http://mywebsite/posts/123-it-is-so-easy

You do

class Post
  def to_param
    "#{id}-#{title.parameterize}"
  end
end

That’s it!
