Marty MacFly

Marty MacFly - Back to the Future to write your Symfony fixtures Marty MacFly allows you to quickly and easily create fixtures to simplify development and testing for Symfony.

Main features

Installing

PHP 8.0+ and Composer are required.

composer req --dev Marty/McFly

You need to create a fixture file per entity and extend Marty\McFly\Fixture instead of Doctrine\Bundle\FixturesBundle\Fixture.

<?php
// src/DataFixtures/CompanyFixtures.php

namespace App\DataFixtures;

use Doctrine\Persistence\ObjectManager;
use Marty\McFly\Fixture;

class CompanyFixtures extends Fixture
{
    public function load(ObjectManager $manager): void
    {
        // $product = new Product();
        // $manager->persist($product);

        $manager->flush();
    }
}

By adding Marty\McFly\Fixture, you must adhere to the Marty\McFly\Interface\CreateInterface interface and add a generate() function.

⚠️ The create() function was renamed to generate() between v1 and v2 to avoid breaking changes. The create() function is still compatible but it is recommended to migrate to generate() to benefit from the new features.

<?php
// src/DataFixtures/CompanyFixtures.php

namespace App\DataFixtures;

use Doctrine\Persistence\ObjectManager;
use Marty\McFly\Fixture;

class CompanyFixtures extends Fixture
{
    public function load(ObjectManager $manager): void
    {
        // $this->generate();

        $manager->flush();
    }

    public function generate(?array $properties = null, array|string|null $references = null): object
    {
        // TODO: Implement generate() method.
        throw new \RuntimeException("The generate() method is not implemented.");
    }
}

Configure your template (generate() is a factory, work with Reflection without setters or _construct)

<?php
// src/DataFixtures/CompanyFixtures.php

namespace App\DataFixtures;

use App\Entity\Company;
use Doctrine\Persistence\ObjectManager;
use Marty\McFly\Fixture;

class CompanyFixtures extends Fixture
{
    public function load(ObjectManager $manager): void
    {
        // Create a random Company, persist it (for database), and automatically add a reference to use it in other fixtures.
        $this->generate();

        // Create 10 randoms Companies to "Paris" (Since 2.0)
        $this->generateMany(10, [
            'city' => 'Paris',
            'postalCode' => '75000'
        ]);

        // Finally, flush to the database
        $manager->flush();
    }

    public function generate(?array $properties = null, array|string|null $references = null): object
    {
        return $this->createAndSave(Company::class, $properties,
            [
                'name'       => self::$faker->company(),
                'address'    => self::$faker->address(),
                'city'       => self::$faker->city(),
                'postalCode' => self::$faker->postcode(),
            ],
            $references
        );
    }

}

Configure your template : The alternative style (using setter if you have) :

<?php
// src/DataFixtures/CompanyFixtures.php

namespace App\DataFixtures;

use App\Entity\Company;
use Doctrine\Persistence\ObjectManager;
use Marty\McFly\Fixture;

class CompanyFixtures extends Fixture
{
    public function load(ObjectManager $manager): void
    {
        // Create a random Company, persist it (for database), and automatically add a reference to use it in other fixtures.
        $this->generate();

        // Alternative : Create 10 randoms Companies to "Paris" with setter
        for ($i=0 ; $i<10 ; $i++) {
            $this->generate()
                ->setCity('Paris')
                ->setPostalCode('75000');
        }

        // Finally, flush to the database
        $manager->flush();
    }

    public function generate(?array $properties = null, array|string|null $references = null): object
    {
        $company = (new Company())
            ->setName(self::getFaker()->company())
            ->setAddress(self::getFaker()->address())
            ->setCity(self::getFaker()->city())
            ->setPostalCode(self::getFaker()->postcode());

        $this->save($company, $references);

        return $company;
    }
}

Usage

Create a random entity

<?php

// ...

class CompanyFixtures extends Fixture
{
    public function load(ObjectManager $manager): void
    {
        // Create a random Company
        $this->generate();

        // Finally, flush to the database
        $manager->flush();
    }

    // ... generate() definition
}

Creating an entity by setting only the necessary properties (recommandation style).

<?php

// ...

class CompanyFixtures extends Fixture
{
    public function load(ObjectManager $manager): void
    {
        // Create a random Company to "Paris"
        $this->generate([
            'city'       => 'Paris',
            'postalCode' => '75000',
        ]);

        // Finally, flush to the database
        $manager->flush();
    }

    // ... generate() definition
}

Creating an entity by setting only the necessary properties (alternative style).

⚠️ With this syntax, the entity is create and change after.

<?php

// ...

class CompanyFixtures extends Fixture
{
    public function load(ObjectManager $manager): void
    {
        // Create a random Company to "Paris"
        $this->generate()
            ->setCity('Paris')
            ->setPostalCode('75000');

        // Finally, flush to the database
        $manager->flush();
    }

    // ... generate() definition
}

Create multiple entities while customizing certain properties.

<?php

// ...

class CompanyFixtures extends Fixture
{
    public function load(ObjectManager $manager): void
    {

        // Create 10 random Company to "Paris"
        $this->generateMany(10, [
            'city'       => 'Paris',
            'postalCode' => '75000',
        ]);

        // Finally, flush to the database
        $manager->flush();
    }

    // ... generate() definition
}

Create multiple entities while customizing certain properties with random values for each element.

<?php

// ...

class CompanyFixtures extends Fixture
{
    public function load(ObjectManager $manager): void
    {

        // Create 10 random Company to "Paris"
        $this->generateMany(10, function() {
            return [
                'city'       => 'Paris',
                'postalCode' => self::$faker->randomElement(['75000', '75100', '75200']),
            ];
        });

        // Finally, flush to the database
        $manager->flush();
    }

    // ... generate() definition
}

Create multiple entities while customizing certain properties (alternative.

<?php

// ...

class CompanyFixtures extends Fixture
{
    public function load(ObjectManager $manager): void
    {

        // Create 10 random Company to "Paris"
        for ($i=0 ; $i<10 ; $i++) {
            $this->generate()
                ->setCity('Hill Valley')
            ;
        }

        // Finally, flush to the database
        $manager->flush();
    }

    // ... generate() definition
}

        $company = $this->getRandomReferenceByClass(Company::class);

        // ..
    }

    public function getDependencies(): array
    {
        return [

                'createdAt' => new DateTimeImmutable(),
                'number'    => InvoiceFixture::count(),                                 // the current number, auto-incrementation on save()
                'user'      => $this->getRandomReferenceByClass(User::class),           // a random User
                'status'    => self::randomValue(Status::cases()),                      // randomly a value of Status Enum,
                'confirmed' => self::randomValue([True, False]),                        // randomly True or False
                'comment'   => self::randomValue([null, self::getFaker()->sentence()]), // Add random sentence or randomly NULL
                'product'
            ],
            $references
        );

        // Add RandomProduct
