This package allows you to map your model attributes to database columns when the type in the PHP model does not match the type in the database column.

This could be using $model->ip_address as a string in your eloquent model but storing it as a BINARY(16) in the database for efficiency. Or having a string always encrypted in the DB but readable in clear form within your models.

$ composer require weebly/laravel-mutate

To use this package, you'll need to add the ServiceProvider to the providers array in config/app.php if you are not using automatic package discovery:

Weebly\Mutate\LaravelMutatorServiceProvider::class

You'll also need to publish the config to config/mutators.php with:

$ php artisan vendor:publish --provider='Weebly\Mutate\LaravelMutatorServiceProvider'

When creating an Eloquent model, you'll need to extend Weebly\Mutate\Database\Model and add $mutate property it:

<?php

namespace App\Models;

use Weebly\Mutate\Database\Model;

class User extends Model
{
    /**
     * {@inheritdoc}
     */
    protected $table = 'users';

    /**
     * {@inheritdoc}
     */
    protected $mutate = [
        'id' => 'uuid_v1_binary'
    ];
}

This will automatically serialize/unserialize the id attribute on the User model when getting/setting the attribute from the database. This allows you to no longer need to set accessors/mutator methods on the model directly.

Note: Unlike the built in Laravel accessors/mutators, this package will serialize the attribute values when they are passed to an Eloquent query builder.

• uuid_v1_binary Will take a uuid version 1, re-order its bytes so that if uuidA was generated before uuidB, then storedUuidA < storedUuidB, and store it in the database as 16 bytes of data. For more information on the re-ordering of bytes, see: https://www.percona.com/blog/2014/12/19/store-uuid-optimized-way/.
• ip_binary Will take a string representation of an IPv4 or IPv6 and store it as 16 bytes in the database.
• encrypt_string Will take a non encrypted string and encrypt it when going to the database.
• hex_binary Will take any hexadecimal string attribute and store it as binary data.
• unix_timestamp Will take a Carbon date but store it as an integer unix timestamp.

To define a custom mutator, you'll need to create a class that implements Weebly\Mutate\Mutators\MutatorContract, and add it to the enabled array in config/mutators.php.

Note: All attributes are cached on a model instance automatically, so you should not need to add any caching logic at the mutator level.

When building and registering a Mutator, it is important to know that they are resolved automatically from the Laravel IOC container, which means you may create service providers for them if they require custom constructor arguments.

<?php

namespace App\Mutators;

use Weebly\Mutate\Mutators\MutatorContract;

class ExampleEncryptMutator implements MutatorContract
{
    /**
     * {@inheritdoc}
     */
    public function serializeAttribute($value)
    {
        return encrypt($value);
    }

    /**
     * {@inheritdoc}
     */
    public function unserializeAttribute($value)
    {
        return decrypt($value);
    }
}
