Using custom faker data providers without standard doctrine fixtures

[reypm]

I am setting up NelmioAlice and Faker in a Symfony2 project through AlixeFixturesBundle. I need a composed fixture like for example:

representative{1..100}:
    veeva_rep_id (unique): qlv_005800000067SwzAAE

which is a qlv_ prefix followed by a random 18 characters string. The best way I found to get this done (if anyone knows another one or a better way to get this done let me know) was using a custom faker and I wrote this piece of code:

<?php
/**
 * FakerProvider: VeevaProvider.
 */

namespace PDI\PDOneBundle\DataFixtures;

use ReverseRegex\Lexer;
use ReverseRegex\Random\SimpleRandom;
use ReverseRegex\Parser;
use ReverseRegex\Generator\Scope;

class VeevaProvider extends \Faker\Provider\Base
{
    public function veevaRepId()
    {
        $lexer = new  Lexer('[a-zA-Z0-9]{18}');
        $gen = new SimpleRandom(10007);
        $result = '';

        $parser = new Parser($lexer, new Scope(), new Scope());
        $parser->parse()->getResult()->generate($result, $gen);

        return 'qlv_' . $result;
    }
}

As explain here in Faker docs. Now, here at NelmioAlice the author explain how to add Custom Faker Data Providers but it uses Doctrine Fixtures which I don't so, having this, how do I load and use the provider I wrote on the fixtures? Any advice around this? How the custom provider should be added and used on this bundle?

Using custom FakerProvider is the way to generate domain-specific data like you have there.
But i cant see, why the Provider has to extend \Faker\Provider\Base, because it does not use anything of that class.

There is a quite straigtforward example in AliceDemo.
Have a look for the provider itself here: https://github.com/h4cc/AliceDemo/blob/master/src/h4cc/AliceDemoBundle/DataFixtures/Alice/Provider/CategoryProvider.php
And the registration of such a provider using dependency injection here: https://github.com/h4cc/AliceDemo/blob/master/src/h4cc/AliceDemoBundle/Resources/config/services.yml
