# Versions

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

The package does not installed by default in Enso.

To install:

1. add the package using composer composer require laravel-enso/versions
2. use the Versions trait on the models you want versioning on
3. ensure the models/tables have the required column, to hold the version
4. add and set the protected $versioningAttribute = 'version' attribute on the versioned models

# Features

• the package uses a column on your model to store the version (the column name is configurable)
• by using the Versions trait on a model, versioning is handled automatically
• by default the trait sets the version to 1, just before the model is created
• the version attribute can be set by using protected $versioningAttribute = 'customVersionAttribtue' on the model
• the trait can be used on models that already have records in the database, the versioning will start with the first retrieval of those models
• throws a ConflictHttpException if the version does not match on update
