Atlas ORM Integration with Symfony - Paul M. Jones

Are you using Symfony 4? Do you want to use Atlas with it? We now have a Symfony bundle and Flex recipe that makes installation and integration a breeze. Two commands and one .env file edit, and you’re ready to go:

composer config extra.symfony.allow-contrib true
composer require atlas/symfony ~1.0

Build out all your mapper files from your database tables with a single command:

php bin/console atlas:skeleton

Then let Symfony inject the Atlas ORM object in your controller or application service constructors automatically (no further configuration needed):

<?php
namespace App;

use Atlas\Orm\Atlas;
use App\DataSource\Thread\Thread
use App\DataSource\Thread\ThreadRecord;

class ApplicationService
{
    public function __construct(Atlas $atlas)
    {
        $this->atlas = $atlas;
    }

    public function fetchThreadById($thread_id) : ThreadRecord
    {
        return $this->atlas->fetchRecord(Thread::class, $thread_id);
    }
}

That’s it – you can now use Atlas for all the heavy lifting of your database work:

• Defining relationships between mappers

• Fetching Records and RecordSets

• Working with Records and RecordSets

• Managing transactions

• Adding behaviors

• Handling events

• Direct lower-level queries

• Other issues such as custom mapper methods, single table inheritance, many-to-many relationships, and automated validation

If you’re looking for a good persistence model data mapper, give Atlas a try!
