Repository.php

<?php namespace Acme\Abstracts;

use Acme\Repositories\RepositoryInterface;

/**
 * The Abstract Repository provides default implementations of the methods defined
 * in the base repository interface. These simply delegate static function calls 
 * to the right eloquent model based on the $modelClassName.
 */

abstract class Repository implements RepositoryInterface {
	
	protected $modelClassName;

	public function create(array $attributes)
	{
		return call_user_func_array("{$this->modelClassName}::create", array($attributes));
	}

	public function all($columns = array('*'))
	{
		return call_user_func_array("{$this->modelClassName}::all", array($columns));
	}

	public function find($id, $columns = array('*'))
	{
		return call_user_func_array("{$this->modelClassName}::find", array($id, $columns));
	}
	
	public function destroy($ids)
	{
