Overview

This package allows you to duplicate any Eloquent model record along with its underlying relationships.

Relationship types that can and will make sense to be duplicated: hasOne, morphOne, hasMany, morphMany, belongsToMany, morphToMany

Installation

Install the package via Composer:

composer require neurony/laravel-duplicate

Usage

Step 1

Your Eloquent models should use the Neurony\Duplicate\Traits\HasDuplicates trait and the Neurony\Duplicate\Options\DuplicateOptions class.

The trait contains an abstract method getDuplicateOptions() that you must implement yourself.

Here's an example of how to implement the trait:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;
use Neurony\Duplicate\Options\DuplicateOptions;
use Neurony\Duplicate\Traits\HasDuplicates;

class YourModel extends Model
{
    use HasDuplicates;
    
    /**
     * Get the options for duplicating the model.
     *
     * @return DuplicateOptions
     */
    public function getDuplicateOptions(): DuplicateOptions
    {
        return DuplicateOptions::instance();
    }
}

Step 2

Once you've used the Neurony\Duplicate\Traits\HasDuplicates trait in your Eloquent models, you can duplicate model records by using the saveAsDuplicate() method present on that trait.

$model = YourModel::find($id);

$duplicatedModel = $model->saveAsDuplicate(); // returns the newly duplicated model instance

Customisations

Exclude certain columns

When duplicating a model, you can exclude certain columns from being duplicated by using the excludeColumns() method in your definition of the getDuplicateOptions() method.

The fields specified in the excludeColumns() method will be saved with their default value (null, false, 0, etc.)

/**
 * Get the options for duplicating the model.
 *
 * @return DuplicateOptions
 */
public function getDuplicateOptions() : DuplicateOptions
{
    return DuplicateOptions::instance()
        ->excludeColumns('column_one', 'column_two');
}

Specify unique columns

When duplicating a model, you can save certain columns in an unique format by using the uniqueColumns() method in your definition of the getDuplicateOptions() method.

The fields specified in the uniqueColumns() method will be saved in a unique format by appending (n) at the end.
Example: original name (1), original name (2)

/**
 * Get the options for duplicating the model.
 *
 * @return DuplicateOptions
 */
public function getDuplicateOptions() : DuplicateOptions
{
    return DuplicateOptions::instance()
        ->uniqueColumns('column_one', 'column_two');
}

Exclude entire relations

By default, when duplicating a model, all of its "child" relations (see Overview) are also duplicated along with it.

You can exclude certain relations from being duplicated by using the excludeRelations() method in your definition of the getDuplicateOptions() method.

The relations specified in the excludeRelations() method will not be duplicated along with the targeted model, meaning that the newly duplicated model will not have any records associated to it for the specified relations.

/**
 * Get the options for duplicating the model.
 *
 * @return DuplicateOptions
 */
public function getDuplicateOptions() : DuplicateOptions
{
    return DuplicateOptions::instance()
        ->excludeRelations('relationOne', 'relationTwo');
}

Exclude certain columns from certain relations

When duplicating a model, you can exclude certain columns of its "child" relations from being duplicated by using the excludeRelationColumns() method in your definition of the getDuplicateOptions() method.

This method accepts only one parameter which should be an associative array containing:
key -> the name of a relation
value -> an array containing the columns to exclude for that relation

The fields specified in the excludeRelationColumns() method will be saved with their default value (null, false, 0, etc.)

/**
 * Get the options for duplicating the model.
 *
 * @return DuplicateOptions
 */
public function getDuplicateOptions() : DuplicateOptions
{
    return DuplicateOptions::instance()
        ->excludeRelationColumns([
            'relationOne' => ['column_one', 'column_two'],
            'relationTwo' => ['column_one'],
        ]);
}

Specify unique columns for certain relations

When duplicating a model, you can save certain columns of its "child" relations in an unique format by using the uniqueRelationColumns() method in your definition of the getDuplicateOptions() method.

This method accepts only one parameter which should be an associative array containing:
key -> the name of a relation
value -> an array containing the unique columns for that relation

The fields specified in the uniqueRelationColumns() method will be saved in an unique format by appending (n) at the end.
Example: original relation name (1), original relation name (2)

/**
 * Get the options for duplicating the model.
 *
 * @return DuplicateOptions
 */
public function getDuplicateOptions() : DuplicateOptions
{
    return DuplicateOptions::instance()
        ->uniqueRelationColumns([
            'relationOne' => ['column_one', 'column_two'],
            'relationTwo' => ['column_one'],
        ]);
}

Duplicate only the targeted model

If you only want to duplicate your targeted model without duplicating any relations whatsoever, you can specify this by using the disableDeepDuplication() method in your definition of the getDuplicateOptions() method.

When using this method, all relations of all types will be ignored when duplicating the model.

/**
 * Get the options for duplicating the model.
 *
 * @return DuplicateOptions
 */
public function getDuplicateOptions() : DuplicateOptions
{
    return DuplicateOptions::instance()
        ->disableDeepDuplication();
}

Events

The duplicate functionality comes packed with two Eloquent events: duplicating and duplicated

You can implement these events in your Eloquent models as you would implement any other Eloquent events that come with the Laravel framework.

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;
use Neurony\Duplicate\Options\DuplicateOptions;
use Neurony\Duplicate\Traits\HasDuplicates;

class YourModel extends Model
{
    use HasDuplicates;

    /**
     * Boot the model.
     *
     * @return DuplicateOptions
     */
    public static function boot()
    {
        parent::boot();

        static::duplicating(function ($model) {
            // your logic here
        });

        static::duplicated(function ($model) {
            // your logic here
        });
    }
    
    /**
     * Get the options for duplicating the model.
     *
     * @return DuplicateOptions
     */
    public function getDuplicateOptions(): DuplicateOptions
    {
        return DuplicateOptions::instance();
    }
}
