Eloquent model cloner
=====================

[](#eloquent-model-cloner)

This package was inspired by  and modified to also work with OctoberCMS installations.

A trait for Laravel Eloquent models that lets you clone a model and it's relationships, including files. Even to another database.

Installation
------------

[](#installation)

To get started with the Eloquent Model Cloner, use Composer to add the package to your project's dependencies:

```
composer require vdlp/eloquent-model-cloner

```

Usage
-----

[](#usage)

Your model should now look like this:

```
class Article extends Eloquent {
   use \Vdlp\EloquentModelCloner\Cloneable;
}
```

You can clone an Article model like so:

```
$clone = Article::first()->duplicate();
```

### Cloning Relationships

[](#cloning-relationships)

Lets say your `Article` has many `Photos` (a one to many relationship) and can have more than one `Authors` (a many to many relationship). Now, your `Article` model should look like this:

```
class Article extends Eloquent {
   use \Vdlp\EloquentModelCloner\Cloneable;

   protected $cloneableRelations = ['photos', 'authors'];

   public function photos() {
       return $this->hasMany('Photo');
   }

   public function authors() {
        return $this->belongsToMany('Author');
   }
}
```

The `$cloneableRelations` informs the `Cloneable` as to which relations it should follow when cloning. Now when you call `Article::first()->duplicate()`, all of the `Photo` rows of the original will be copied and associated with the new `Article`. And new pivot rows will be created associating the new `Article` with the `Authors` of the original (because it is a many to many relationship, no new `Author` rows are created). Furthermore, if the `Photo` model has many of some other model, you can specify `$cloneableRelations` in its class and `Cloner` will continue replicating them as well.

### Customizing the cloned attributes

[](#customizing-the-cloned-attributes)

By default, `Cloner` does not copy the `id` (or whatever you've defined as the `key` for the model) field; it assumes a new value will be auto-incremented. It also does not copy the `created_at` or `updated_at`. You can add additional attributes to ignore as follows:

```
class Photo extends Eloquent {
   use \Vdlp\EloquentModelCloner\Cloneable;

   protected $cloneExemptAttributes = ['uid', 'source'];

   public function article() {
        return $this->belongsTo('Article');
   }

   public function onCloning($src, $child = null) {
        $this->uid = str_random();

        if ($child) {
            echo 'This was cloned as a relation!';
        }

        echo 'The original key is: ' . $src->getKey();
   }
}
```

The `$cloneExemptAttributes` adds to the defaults. If you want to replace the defaults altogether, override the trait's `getCloneExemptAttributes()` method and return an array.

Also, note the `onCloning()` method in the example. It is being used to make sure a unique column stays unique. The `Cloneable` trait adds to no-op callbacks that get called immediately before a model is saved during a duplication and immediately after: `onCloning()` and `onCloned()`. The `$child` parameter allows you to customize the behavior based on if it's being cloned as a relation or direct.

In addition, Cloner fires events during cloning and when the model has been cloned, see:

- `\Vdlp\EloquentModelCloner\Events\Cloned`
- `\Vdlp\EloquentModelCloner\Events\Cloning`

The event payload contains the clone and the original model instances.
