Introduction
A simple drop-in solution for providing UUID support for the IDs of your
Eloquent models.
Both v1 and v4 IDs are supported out of the box, however should you need
v3 or v5 support, you can easily add this in.
Installing
Reference the table below for the correct version to use in conjunction with the
version of Laravel you have installed:, Laravel, This package, -------, ------------, v5.8.*, v1.*, v6.*, v6.*, You can install the package via composer:
composer require goldspecdigital/laravel-eloquent-uuid:^v6.2
Usage
There are two ways to use this package:
- By extending the provided model classes (preferred and simplest method).
- By using the provided model trait (allows for extending another model class).
Extending model
When creating a Eloquent model, instead of extending the standard Laravel model
class, extend from the model class provided by this package:
<?php
namespace App\Models;
use GoldSpecDigital\LaravelEloquentUUID\Database\Eloquent\Model;
class BlogPost extends Model
{
//
}
Extending user model
The User model that comes with a standard Laravel install has some extra
configuration which is implemented in its parent class. This configuration only
consists of implementing several interfaces and using several traits.
A drop-in replacement has been provided which you can use just as above, by
extending the User class provided by this package:
<?php
namespace App\Models;
use GoldSpecDigital\LaravelEloquentUUID\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
//
}
Using trait
As an alternative to extending the classes in the examples above, you also have
the ability to use the provided trait instead. This requires a more involved
setup process but allows you to extend your models from another class if needed:
<?php
namespace App\Models;
use GoldSpecDigital\LaravelEloquentUUID\Database\Eloquent\Uuid;
use Illuminate\Database\Eloquent\Model;
class BlogPost extends Model
{
use Uuid;
/**
* The "type" of the auto-incrementing ID.
*
* @var string
*/
protected $keyType = 'string';
/**
* Indicates if the IDs are auto-incrementing.
*
* @var bool
*/
public $incrementing = false;
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $guarded = [];
}
Generating UUIDs
If you don't specify the value for the primary key of your model, a UUID will
be automatically generated. However, if you do specify your own UUID then it
will not generate one, but instead use the one you have explicitly provided.
This can be useful when needing the know the ID of the model before you have
created it:
// No UUID provided (automatically generated).
$model = Model::create();
echo $model->id; // abb034ae-fcdc-4200-8094-582b60a4281f
// UUID explicity provided.
$model = Model::create(['id' => '04d7f995-ef33-4870-a214-4e21c51ff76e']);
echo $model->id; // 04d7f995-ef33-4870-a214-4e21c51ff76e
Specifying UUID versions
By default, v4 UUIDs will be used for your models. However, you can also
specify v1 UUIDs to be used by setting the following property/method on your
model:
When extending the class
<?php
namespace App\Models;
use GoldSpecDigital\LaravelEloquentUUID\Database\Eloquent\Model;
class BlogPost extends Model
{
/**
* The UUID version to use.
*
* @var int
*/
protected $uuidVersion = 1;
}
When using the trait
<?php
namespace App\Models;
use GoldSpecDigital\LaravelEloquentUUID\Database\Eloquent\Uuid;
use Illuminate\Database\Eloquent\Model;
class BlogPost extends Model
{
use Uuid;
/**
* The UUID version to use.
*
* @return int
*/
protected function uuidVersion(): int
{
return 1;
}
}
Support for v3 and v5
Should you need support for v3 or v5 UUIDs, you can simply override the
method which is responsible for generating the UUIDs:
<?php
namespace App\Models;
use GoldSpecDigital\LaravelEloquentUUID\Database\Eloquent\Model;
use Ramsey\Uuid\Uuid;
class BlogPost extends Model
{
/**
* @throws \Exception
* @return string
*/
protected function generateUuid(): string
{
// UUIDv3 has been used here, but you can also use UUIDv5.
return Uuid::uuid3(Uuid::NAMESPACE_DNS, 'example.com')->toString();
}
}
Creating models
In addition of the make:model artisan command, you will now have access to
uuid:make:model which has all the functionality of the standard make:model
command (with exception of not being able to create a pivot model):
php artisan uuid:make:model Models/Post --all
Database migrations
The default primary ID column used in migrations will not work with UUID primary
keys, as the default column type is an unsigned integer. UUIDs are 36 character
strings so we must specify this in our migrations:
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateUsersTable extends Migration
{
/**
* Run the migrations.
*/
public function up(): void
{
Schema::create('users', function (Blueprint $table): void {
// Primary key.
$table->uuid('id')->primary();
});
}
}
class CreatePostsTable extends Migration
{
/**
* Run the migrations.
*/
public function up(): void
{
Schema::create('posts', function (Blueprint $table): void {
// Primary key.
$table->uuid('id')->primary();
// Foreign key.
$table->uuid('user_id');
$table->foreign('user_id')->references('id')->on('users');
});
}
}
Running the tests
To run the test suite you can use the following commands:
# To run both style and unit tests.
composer test
# To run only style tests.
composer test:style
# To run only unit tests.
composer test:unit
If you receive any errors from the style tests, you can automatically fix most,
if not all of the issues with the following command:
composer fix:style
