A Laravel Eloquent Model trait for adding and using a uuid with models.
The trait listens to the creating event. It generates a new UUID and saves it in the uuid column on the model.

composer require jamesmills/eloquent-uuid
In order to use this in your models, just put use HasUuidTrait;
<?php
namespace App;
use JamesMills\Uuid\HasUuidTrait;
class User extends Eloquent
{
use HasUuidTrait;
}In order to use this trait, your schema must be something like:
<?php
// ...
Schema::create('users', function (Blueprint $table) {
$table->primary('id');
$table->uuid('uuid')->unique(); // this will create a CHAR(36) field
$table->string('username', 32);
$table->string('password', 50);
// ...
});You may use the findByUuidOrFail method to try and fetch a model directly:
<?php
Route::get('/user/{uuid}', function($uuid) {
try {
return App\User::findByUuidOrFail($uuid);
} catch (Illuminate\Database\Eloquent\ModelNotFoundException $e) {
abort(404);
}
});Since uuid gets registered as Route Key using implicit binding[https://laravel.com/docs/5.8/routing#implicit-binding], your resource controllers will use uuid instead of default id column.
<?php
php artisan make:controller UserController --resource/users/{user} route uses uuid i.e. /users/bff37872-1450-47c7-b9f7-9a6d917796cf
You may also use the withUuid and withUuids local query scopes with the query builder.
<?php
Route::get('/user/{uuid}', function($uuid) {
$user = App\User::withUuid($uuid)->first();
if (! $user) {
// Do something else...
}
});<?php
Route::delete('/users', function(Request $request) {
// Receive an array of UUIDs
$uuids = $request->input('uuids');
// Try to get the Users
$users = App\User::withUuids($uuids)->all();
// Handle the delete and return
$users->delete();
});
