Usage

Duplicate View

In your Controller class add PcWeb\DuplicateController\Behaviors\DuplicateController to the list of implemented behaviors.

public $implement = [
        'Backend\Behaviors\ListController',
        'Backend\Behaviors\FormController',
        'Backend\Behaviors\RelationController',
        'PcWeb\DuplicateController\Behaviors\DuplicateController'
    ];

in your update view or list view add an link to the duplicate/[model-id] action.

UpdateView:

<a href="<?= Backend::url('pcweb/myplugin/mycontroller/duplicate/', $formModel->id) ?>">Duplicate</a>

ListView:

<a href="<?= Backend::url('pcweb/myplugin/mycontroller/duplicate/', $recordId) ?>">Duplicate</a>

Create a file similar to the create.htm inside the controller views folder.

The file could look like follows:

<?php Block::put('breadcrumb') ?>
    <ul>
        <li>
            <a href="<?= Backend::url('pcweb/myplugin/mycontroller') ?>">MyController</a>
        </li>
        <li><?= e($this->pageTitle) ?></li>
    </ul>
<?php Block::endPut() ?>

<?php if (!$this->fatalError): ?>

    <?php Block::put('form-contents') ?>

    <div class="layout-row min-size">
        <?= $this->formRenderOutsideFields() ?>
    </div>

    <div class="layout-row">

    <div class="form-buttons">

                    class="btn btn-default">

                    data-load-indicator="<?= e(trans('backend::lang.form.deleting')) ?>"
                    data-request-confirm="<?= e(trans('backend::lang.form.confirm_delete')) ?>">

            <span class="btn-text">

You have to update all lines containing Backend::url(...

A new Model opens with all attributes duplicated.

You can customize attributes to duplicate with the $duplicates property in the model. You can also include relations in this array. Relation duplicates are handled with Defered Bindings

For example: public $duplicates = ['relBelongsToMany', 'relBelongsTo', 'relHasOne', 'relHasMany', 'name'];

Extend Duplicate Logic

you can define the method formExtendDuplicate in your controller to handle additional actions after duplication.

public function formExtendDuplicate($model, $existing)
{
// ...
}

Known issues: Many2Many relations don't get duplicated, they are linked instead. If you would like to clone the rows inside the relation table, you have to use the formExtendDuplicate in the controller.
