Create Initial versions of model.

[mansoorkhan96]

Thanks for amazing work on this really hand package ❤️

I found an issue with version keeping, so here is an explaination.

Problem

When saving a Model for first time, It does not save the existing state of the model, instead it starts saving the new state of the model.

Steps to reproduce

Assuming, we have a Model with existing data:

$existingPost = [
  'id' => 1,
  'title' => 'Existing Title',
];

Update the title of model

$post->update([
  'title' => 'New Title'
]);

Expected behaviour:

We expect a version with title = Existing Title and optionally another version with title = New Title which matches the state of original/source Model.

Actual behaviour:

We are losing a version where title = Existing Title.

Possible Solution

It should create an initial version of the model first and then start saving the new versions.

Work around

I have a single Model called Post which uses the Versionable trait. So I created a console command SetupVersionable to create the initial versions of the Post model, before writers/users start changing the content.

use Overtrue\LaravelVersionable\Version;

class SetupVersionable extends Command
{
    protected $signature = 'app:setup-versionable';

  
    public function handle()
    {
        Post::all()
            ->each(fn (Post $post) => Version::createForModel($post, $post->only($post->versionable)));
    }
}
