This plugin add RevisionableController a Controller Behavior for display revisions history on the backend

1. Ensure your model have the Revisionable Trait
2. Add behavior \Inetis\Revisionable\Behaviors\RevisionableController::class to your Controller
   This will make available the list of model changes at this URL vendor/plugin/model/history/$id
3. Add "Show history" button on Preview (preview.htm) file of your controller

   <a href="<?= Backend::url('vendor/plugin/model/history/' . $formModel->id) ?>"
      class="btn btn-default oc-icon-history">
       <?= e(trans('inetis.revisionable::lang.btn_show_history')) ?>
   </a>

If your revisions also store the user id (see documentation) you can register the relation in your Plugin.php file for that the name of the user be displayed in history table.

use October\Rain\Database\Models\Revision;

class Plugin extends PluginBase
{
    // [ ... ]

    public function boot()
    {
        // [ ... ]

        Revision::extend(function (Revision $revision) {

            // If you use Backend user
            $revision->belongsTo['user'] = [\Backend\Models\User::class];

            // or if you use Frontend user
            $revision->belongsTo['user'] = [\RainLab\User\Models\User::class];

        });
    }
}

You can override the default rendering of the history page (plugins/inetis/revisionable/behaviors/revisionablecontroller/partials/_container.htm) by creating a _revisionable_container.htm file in the views directory of your controller.

By default the Backend user timezone is used but you can override that by creating a file in /config/inetis/revisionable/config.php with you desired timezone (see below)

<?php

return [

    /**
     * Timezone used for display modification date 
     * by default use Backend timezone : \Backend\Models\Preference::get('timezone')     
     * but you can override it to a regional timezone e.g.: 'Europe/Zurich'
     */
    'timezone' => 'Europe/Zurich',

];
