README

A Laravel package for managing reivision of database. (This package is for Laravel 5+)

• Note: This package is inspired by VentureCraft/revisionable. Thank you, VentureCraft!

Installation

Execute the following composer command.

composer require sukohi/back-then:1.*

then set BackThenServiceProvider in your config/app.php.

Sukohi\BackThen\BackThenServiceProvider::class, 

Preparation

To make a table for this package, execute the following commands.

php artisan vendor:publish --provider="Sukohi\BackThen\BackThenServiceProvider"

and

php artisan migrate

Add BackThenTrait to your model like so.

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;
use Sukohi\BackThen\BackThenTrait;

class Product extends Model
{
    use BackThenTrait;

That's all.
Now when you create, update or delete record, this package automatically will save revision record(s).

Usage

You can save and delete record as usual like so.

$product = new \App\Product();
$product->name = 'xxxxxxx';
$product->save();   // Revision record will be saved.

$product = \App\Product::find(1);
$product->name = 'yyyyyyy';
$product->save();   // Revision record will be saved.

$product->delete();   // Revision record will be saved.

Save user ID

You can save ID of user who saved/deleted through revision_user_id.

$product = \App\Product::find(1);
$product->revision_user_id = 1; // User ID you want to save.
$product->save();

Retrieve Current Revision ID and Unique ID

echo $product->revision_id;
echo $product->revision_unique_id;

• You can change revision you want via revision ID or unique ID.

Change Revision

via changeRevisionById

$revision_id = 1;

if($product->hasRevisionId($revision_id)) {

    $product->changeRevisionById($revision_id); // This has old values.

}

or via changeRevision

$unique_id = '5a906ea1934196bc065f1b22eafd90c9';

if($product->hasRevisionUniqueId($unique_id)) {

    $product->changeRevision($unique_id); // This has old values.

}

Note: Once you call changeRevisionById() or changeRevision(), the model has old values.
This means if you save it, of cause, the latest value will be replaced with the old ones.
So don't forget to call clearRevision() if you need to save at the same time.

Return to the Latest Revision

$product->clearRevision();

Revision Columns

If you'd like this package to save specific revision record.
Set column names in your model like so.

protected $revisions = ['column_name'];

or

protected $ignore_revisions = ['column_name'];

Retrieve Revision data

$histories = $product->revisionHistory; // All revisions

or

$revision = $product->getRevisionById(1);   // A specific revision
$revision = $product->getRevision('5a906ea1934196bc065f1b22eafd90c9');// A specific revision
