Prevents update conflicts using the optimistic lock pattern in Laravel

This package can work independently of the Liberu ecosystem.

For live examples and demos, you may visit


  1. install the package composer require laravel-liberu/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).


  • 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
