README

Nice and easy way to handle revisions of your db.

• Handles the revisions in bulk - one entry covers all the created/updated fields, what makes it really easy to eg. compare 2 given versions or get all the data changed during single action.

Requirements

• This package requires PHP 5.4+
• Currently it works out of the box with Laravel5 + generic Illuminate Guard, tymon/jwt-auth OR cartalyst/sentry 2/sentinel 2

Usage (Laravel5 basic example - see Customization below as well)

1. Download the package or require in your composer.json:

    "require": {
        ...
        "sofa/revisionable": "~1.0@dev",
        ...
    },

2. Add the service provider to your app/config/app.php:

    'providers' => array(

        ...

        'Sofa\Revisionable\Laravel\ServiceProvider',
    ),

3. Publish the package config file:

~$ php artisan vendor:publish [--provider="Sofa\Revisionable\Laravel\ServiceProvider"]

this will create config/sofa_revisionable.php file, where you can adjust a few settings:

<?php

return [

    /*
    |--------------------------------------------------------------------------
    | User provider (auth) implementation.
    |--------------------------------------------------------------------------
    |
    | By default Laravel generic Illuminate\Auth\Guard.
    |
    | Supported options:
    |  - illuminate
    |  - sentry
    |  - sentinel
    |  - jwt-auth
    */
    'userprovider' => 'illuminate',


    /*
    |--------------------------------------------------------------------------
    | User field to be saved as the author of tracked action.
    |--------------------------------------------------------------------------
    |
    | By default:
    |
    |  - id for illuminate
    |  - login field (email) for sentry/sentinel
    |  - id or ANY field in User model for tymon/jwt-auth
    */
    'userfield'    => null,


    /*
    |--------------------------------------------------------------------------
    | Table used for the revisions.
    |--------------------------------------------------------------------------
    */
    'table'        => 'revisions',


    /*
    |--------------------------------------------------------------------------
    | Set timezone
    |--------------------------------------------------------------------------
    */
    'timezone'     => 'Asia/Manila',


    /*
    |--------------------------------------------------------------------------
    | Set date time format
    |--------------------------------------------------------------------------
    */
    'datetime_format'     => 'Y-m-d H:i:s',

];

4. Run the migration in order to create the revisions table:

~$ php artisan migrate [--database=custom_connection]

You can provide additional --database param if you want the migration to be run using non-default db connection.

5. Add revisionable trait and contract to the models you wish to keep track of:

<?php namespace App;

use Sofa\Revisionable\Laravel\RevisionableTrait; // trait
use Sofa\Revisionable\Revisionable; // interface

class User extends \Eloquent implements Revisionable {

    use RevisionableTrait;

    /*
     * Set revisionable whitelist - only changes to any
     * of these fields will be tracked during updates.
     */
    protected $revisionable = [
        'email',
        'name',
    ];

And that's all to get your started!

Customization in L5

Default behaviour:

namespace App\Models;

use Sofa\Revisionable\Revisionable;
use Sofa\Revisionable\Laravel\RevisionableTrait;


class Ticket extends \Eloquent implements Revisionable {

    use RevisionableTrait;
}

$ php artisan tinker

>>> $ticket = App\Models\Ticket::first();
=> <App\Models\Ticket>

>>> $revision = $ticket->latestRevision;
=> <Sofa\Revisionable\Laravel\Revision>

>>> $revision->getDiff();
=> [
       "customer_id"    => [
           "old" => "1",
           "new" => "101"
       ],
       "item_id"        => [
           "old" => "2",
           "new" => "1"
       ],
       "responsible_id" => [
           "old" => "8",
           "new" => "2"
       ]
   ]

>>> $revision->old('item_id');
=> "2"

>>> $revision->new('item_id');
=> "1"

>>> $revision->isUpdated('item_id');
=> true

>>> $revision->isUpdated('note');
=> false

>>> $revision->label('item_id');
=> "item_id"

>>> $revision->old;
=> [
       "defect"         => "nie dziala",
       "note"           => "wrocilo na gwarancji",
       "customer_id"    => "1",
       "item_id"        => "2",
       "responsible_id" => "8",
       "status_id"      => "6"
   ]

>>> $revision->action;
=> "updated"

But here's where you can leverage bundled Presenter in order to make useful adjustments:

namespace App\Models;

use Sofa\Revisionable\Revisionable;
use Sofa\Revisionable\Laravel\RevisionableTrait;


class Ticket extends \Eloquent implements Revisionable {

    use RevisionableTrait;

    protected $revisionPresenter = 'App\Presenters\Revisions\Ticket';
}

namespace App\Presenters\Revisions;

use Sofa\Revisionable\Laravel\Presenter;

class Ticket extends Presenter {

    protected $labels = [
        'item_id'        => 'Przedmiot',
        'customer_id'    => 'Klient',
        'status_id'      => 'Status',
        'responsible_id' => 'Serwisant',
        'defect'         => 'Usterka',
        'note'           => 'Uwagi',
    ];

    protected $passThrough = [
        'item_id'        => 'item.name',
        'customer_id'    => 'customer.name',
        'responsible_id' => 'serviceman.name',
        'status_id'      => 'status.name',
    ];

    protected $actions = [
        'created'  => 'utworzony',
        'updated'  => 'edytowany',
        'deleted'  => 'usunięty',
        'restored' => 'przywrócony',
    ];

}

then

$ php artisan tinker

>>> $ticket = App\Models\Ticket::first();
=> <App\Models\Ticket>

>>> $revision = $ticket->latestRevision; // automatically wrapped in presenter
=> <App\Presenters\Revisions\Ticket>

>>> $revision->old('item_id'); // value fetched from the relationship
=> "komputer pc"

>>> $revision->new('item_id'); // value fetched from the relationship
=> "laptop acer"

>>> $revision->label('item_id'); // custom label defined in the presenter
=> "Przedmiot"

>>> $revision->action; // custom action name defined in the presenter
=> "edytowany"
