# Versioning

Prevents update conflicts using the optimistic lock pattern in Laravel.

This package can work independently of the Enso ecosystem.

For live examples and demos, you may visit laravel-enso.com

# Installation

Comes pre-installed in Enso.

To install outside of Enso:

1. install the package composer require laravel-enso/versioning
2. run the migrations
3. use the Versionable trait on the models you want versioning on.

By default, the version value is kept in a 'version' attribute, but this can be customized (see below).

# Features

• the package creates a versionings table where it holds versions for all the versionable models
• by using the Versionable trait on a model, versioning is handled automatically
• by default the trait appends a version attribute after the model is retrieved, used for tracking versions and expects the same attribute to be present on the model when the update is called
• the default versioning attribute can be customized by using protected $versioningAttribute = 'customVersionAttribte' on the model
• the trait can be used on models that already have records in the database, the versioning starts with the first retrieval of those models
• when a versionable model is deleted, its versioning is deleted also. If the model uses SoftDeletes, the versioning is not deleted, unless doing a forceDelete
• throws a ConflictHttpException if the version does not match on update
• tests are included with the package
