Custom Alice Faker Function

hey mate. Thanks alot for this video series, its really great! during the very last step after i add the private $isPublished colums, i add the setter public function setIsPublished($isPublished). wehn i run the php bin/console doctrine:fixtures:load command i get the following error.

PS D:\xampp\htdocs\aqua_note> php bin/console doctrine:fixtures:load

why does is it trying to make name null at all, we only added that nullable=true stipulation to the $funFact column

also it did not do this until i added the isPublished column, before that it worked fine

This is amazing. This tool will replace my old "O Incrível Enchedor de Linguiça" !!!!

Hey guys, quick doctrine migration question. Is there a way to specify executing the last created diff? If there are old diffs in my DoctrineMigrations directory and I don't delete them it tries to run those before the latest diff. Is that normal behavior?

I need to generate a value that is less than the value faker has generated in another field. If I create a custom provider, how do I pass in the value that faker has created for the other field? i.e

stock: <numberbetween(100,5000)> //Produces 823
reorderQty: <customreorderqty($stock)> //Would return a value less than 823

Thanks

Hi Guys. First of all great work; love your tutorials. I was trying to code along using latest Alice version and obviously run into buch of problems. I tried to use there solution, however I couldn't use <i>$this->container</i> inside <em>LoadFixtures.php</em>; duno why :/ So I played with it for couple hours and came up with this:

<strong>1.</strong> I read <a>https://github.com/nelmio/alice/blob/master/doc/customizing-data-generation.md#custom-faker-data-providers&lt;/a&gt; and based on docs created my <i>GenusProvider</i> class like this:

namespace AppBundle\DataFixtures\ORM;
class GenusProvider
{
    public function genus()
    {
        $genera = [
            'Octopus',
            'Baleana',
            'Orcinus',
            'Hippocampus',
            'Asterias',
            'Amphiprion',
            'Carcharodon',
            'Aurelia',
            'Cucumaria',
            'Balistoides',
            'Paralithodes',
            'Chelonia',
            'Trichechus',
            'Eumetopias'
        ];

        $key = array_rand($genera);

        return $genera[$key];
    }
}

If you look carefully, you can see I didn't extend BaseProvider. I tried but it didn't work in my case.

<strong>2.</strong> Then you should:
<blockquote>Then you can add it to the Faker Generator used by Alice by either overriding the NativeLoader::createFakerGenerator() method.</blockquote>
This was the hardest part because in tutorial we don't mess with the loader class. This is where I spent most of the time. My solution is to extend the <i>NativeLoader</i> class like this:

namespace AppBundle\DataFixtures\ORM;

use Nelmio\Alice\Loader\NativeLoader;
use Faker\Factory as FakerGeneratorFactory;
use Faker\Generator as FakerGenerator;

class NewNativeLoader extends NativeLoader
{
    protected function createFakerGenerator(): FakerGenerator
    {
        $generator = FakerGeneratorFactory::create(parent::LOCALE);
        $generator->addProvider(new GenusProvider());
        $generator->seed($this->getSeed());

        return $generator;
    }
}

As you can see this the place where all the add-provider-magic happens. I overrode <i>createFakerGenerator</i> method and used new fance <i>GenusProvider</i>

<strong>3. </strong> Now let's go back to original <i>LoadFixtures.php</i>. Instead of using <i>NativeLoader</i> i used my <i>NewNativeLoader</i>. Code looks like this:

namespace AppBundle\DataFixtures\ORM;

use Doctrine\Bundle\FixturesBundle\Fixture;
use Doctrine\Common\Persistence\ObjectManager;

class LoadFixtures extends Fixture
{
    public function load(ObjectManager $manager)
    {
        $loader = new NewNativeLoader();

        $objectSet = $loader->loadFile(__DIR__.'/fixtures.yml')->getObjects();
        foreach($objectSet as $object) {
            $manager->persist($object);
        }
        $manager->flush();
    }
}

• All the files mentioned (<i>GenusProvider.php</i>, <i>LoadFixtures.php</i>, <i>NewNativeLoader.php</i>) live in the same ...\ORM directory
• I didn't mess with the services as it had no impact and i still ended up seeing "unknown formatter" message in the console
• I will try to put my code on github as soon as I finish the Symfony 3 tutorials

I bet there is a better way to solve this; mine just works ;)

Why is my phpstorm adding comments for the return/parameter type when I create a getter or setter using Code Generation? Abd its only calling the type "mixed". Not boolean, for example even though it's an "isPublished" type format for the name. I see your PHPStorm doesn't produce these php doc type comments. eg

/**
* @param mixed $isPublished
*/
public function setIsPublished($isPublished)
{
$this->isPublished = $isPublished;
}

If anyone is using Alice 3.0, you will need to create a GenusProvider class based off https://github.com/nelmio/alice/blob/master/doc/customizing-data-generation.md#custom-faker-data-providers. I stuck it in the same folder as my LoadFixtures.php so it had the namespace AppBundle\DataFixtures\ORM and dropped the genus() function in there.

You also need to changed services.yml to get Alice to pick up the new provider. Under the services:

AppBundle\DataFixtures\ORM\GenusProvider:
   tags: [nelmio_alice.faker.provider]

After that run ./bin/console doctrine:fixtures:load again and it should be working OK.
