An Example ActiveRecord model

user.php

<?php
// Need to add 'activerecord' to your packages in config.php
namespace Fuel\Application;

use ActiveRecord;

class Model_User extends ActiveRecord\Model {

	// This will eventually be "guessed"
	protected static $table_name = 'users';

	protected $columns = array('id', 'name');
	
}

welcome.php

<?php
/**
 * Example Usage of the ActiveRecord Model.
 * Associations do not currently work
 */
namespace Fuel\Application;

class Controller_Welcome extends Controller\Base {

	public function action_index()
	{
		$user = Model_User::find(2);
		echo $user->name;
		$user->name = 'Jacob';
		$user->save();
		
		$user = new Model_User();
		$user->name = 'Joe Smith';
		$user->save();
	}
}

Storing columns in the model really shouldn't be needed and can easily be guessed using a DESCRIBE query :) https://github.com/YorickPeterse/Awesome-Record/blob/develop/libraries/Awesome_record.php#L241

That is just temporary. It will go away soon.
