Penggunaan :

  1. Pastikan Anda sudah membuat folder Simple/Services didalam folder app.
    Seperti ini:
- laravel/
  |-- app/
      |-- Smile
          |-- Services
              |-- Creators
                  |-- Creator.php
                  |-- CreatorException.php
                  |-- CreatorInterface.php
  1. Buat class yang meng-extend ke class Simple\Services\Creators\Creator.
    Dan jangan lupa untuk meletakannya di folder app/Smile/Services/Creators juga.
    Contohnya seperti dibawah ini.
<?php namespace Smile\Services\Creators;

use Smile\Services\Creators\CreatorException;

class UserCreator extends Creator
{
    protected $model = 'User';

    protected $rules = [
        'username'      => 'required|max:15',
        'email'         => 'required|email',
        'password'      => 'required',
    ];

    public function create($input)
    {
        if($this->isValid($input))
        {
            $this->model->create($input);
            return true;
        }
        throw new CreatorException($this->getErrors());     
    }
}
  1. Nanti di controller nya gini:
<?php

use Smile\Services\Creators\UserCreator as Creator;

class UsersController extends BaseController
{
    protected $creator;

    public function __construct(Creator $creator) {
        $this->creator = $creator;
    }

    public function store()
    {
        try
        {
            $this->creator->create(Input::all());
            return Redirect::route('users.index')
                ->withFlashSuccess('Pengguna baru berhasil dibuat.')
            ;
        }
        catch(CreatorException $e)
        {
            return Redirect::back()
                ->withInput()
                ->withErrors($e->getErrors())
                ->withFlashError('Whoops, ada yang error.');
            ;
        }
    }
}
  1. Selesai
