README

Adds "soft"-delete support to CakePHP tables.

Install

Using Composer:

composer require muffin/trash

You then need to load the plugin. You can use the shell command:

bin/cake plugin load Muffin/Trash

Usage

In your table(s), add the behavior like you would for any other behavior:

// in the initialize() method
$this->addBehavior('Muffin/Trash.Trash');

By default, the behavior expects your table to have a nullable DATETIME column named deleted or trashed. Or you could customize the name when adding the behavior:

// in your table's initialize() method
$this->addBehavior('Muffin/Trash.Trash', [
    'field' => 'deleted_at'
]);

or, at the global level, in bootstrap.php:

Configure::write('Muffin/Trash.field', 'deleted_at');

Finally, if you would like to keep the default cake behavior when running find() or delete() operations and explicitly call the behavior when you need 'trash'-ing functionality, just disable the event(s):

// in the initialize() method
$this->addBehavior('Muffin/Trash.Trash', [
    'events' => ['Model.beforeFind'] // enables the beforeFind event only, false to disable both
]);

or use the purge option:

$table->delete($entity, ['purge' => true]);

Detecting trashing

If you need to distinguish between deletion and trashing the behavior adds the ['trash' => true ] option to the afterDelete event it creates when trashing.

Cascading deletion

If you'd like to have related records marked as trashed when deleting a parent item, you can just attach the behavior to the related table classes, and set the 'dependent' => true, 'cascadeCallbacks' => true options in the table relationships.

This works on relationships where the item being deleted in the owning side of the relationship. Which means that the related table should contain the foreign key.

If you don't want to cascade on trash:

// in the initialize() method
$this->addBehavior('Muffin/Trash.Trash', [
    'cascadeOnTrash' => false,
]);

Custom Finders

• onlyTrashed - helps getting only those trashed records.
• withTrashed - when filtering out the trashed records by default, this method comes in handy to have them included as part of certain calls.

Extras

• emptyTrash() - permanently deletes all trashed records.
• restoreTrash($entity = null, array $options = []) - restores one (or all) trashed records.
• cascadingRestoreTrash($entity = null, array $options = []) - restores one (or all) trashed records including those of dependent associations.
• trash($entity, array $options = []) - like delete() but for a soft-delete (handy when Model.beforeDelete is disabled by default).
• trashAll(array $conditions) - like deleteAll() but for soft-deletes.

Patches & Features

• Fork
• Mod, fix
• Test - this is important, so it's not unintentionally broken
• Commit - do not mess with license, todo, version, etc. (if you do change any, bump them into commits of their own that I can ignore when I pull)
• Pull request - bonus point for topic branches

To ensure your PRs are considered for upstream, you MUST follow the CakePHP coding standards.
