Easy model urls for Rails

One part url params

class Player < ActiveRecord::Base

  def url_params
    return { :controller => 'players', :action => 'info', :id => username }
  end

end

One part url_for override

class ApplicationController < ActionController::Base

  def url_for(options, *params)
    if options.include? :model then
      options = options.delete(:model).url_params.merge options
    end

    return super(options, *params)
  end

end

[Simplified due to some insight from zenspider]

Then just add :model => AR_object to anything that accepts url params:

<ul>
<% @players.each do |player| -%>
<li><%= link_to player.username, :model => player %>
<% end -%>
</ul>

And ba-bam!

<ul>
<li><a href="/players/info/herbert">herbert</a>
<li><a href="/players/info/joseph">joseph</a>
</ul>
