Change Faker Locale in Laravel 5.2

Is there a way to specify the Faker locale in the database/factories/ModelFactory.php file ? Here is my non functioning attempt at doing so >,<

$factory->define(App\Flyer::class, function (Faker\Generator $faker) {

    // What is the correct way of doing this?
    $faker->locale('en_GB'); 

    return [
        'zip' => $faker->postcode,
        'state' => $faker->state,  
    ];
});

Thanks for reading!

Faker locale can be configured in the config/app.php configuration file. Just add the key faker_locale.

e.g.: 'faker_locale' => 'fr_FR',

THIS ANSWER IS ONLY VALID FOR LARAVEL <=5.1 OR WHEN YOU WANT TO USE MANY DIFFERENT LOCALES see this answer for a solution in Laravel >=5.2.

To use a locale with Faker, the generator needs creating with the locale.

$faker = Faker\Factory::create('fr_FR'); // create a French faker

From the faker documentation:

If no localized provider is found, the factory fallbacks to the default locale (en_EN).

Laravel by default, binds the creation of a faker instance in the EloquentServiceProvider. The exact code used to bind is:

// FakerFactory is aliased to Faker\Factory
$this->app->singleton(FakerGenerator::class, function () {
    return FakerFactory::create();
});

It would appear that Laravel has no way to modify the locale of the faker instance it passes into the factory closures as it does not pass in any arguments to Faker.

As such you would be better served by using your own instance of Faker in the factory method.

$localisedFaker = Faker\Factory::create("fr_FR");

$factory->define(App\Flyer::class, function (Faker\Generator $faker) {

    // Now use the localisedFaker instead of the Faker\Generator
    // passed in to the closure.
    return [
        'zip' => $localisedFaker->postcode,
        'state' => $localisedFaker->state,  
    ];
});

I prefer to use it:

$fakerBR = Faker\Factory::create('pt_BR');

$factory->define(App\Flyer::class, function (Faker\Generator $faker) use (fakerBR) {

    return [
        'name'  => $fakerBR->name,
        'cpf'   => $fakerBR->cpf,
        'zip'   => $faker->postcode,
        'state' => $faker->state,  
    ];
});

Late in the party, but after some research I've found this in faker documentation:

[...] since Faker starts with the last provider, you can easily override existing formatters: just add a provider containing methods named after the formatters you want to override.

That means that you can easily add your own providers to a Faker\Generator instance.

So you can do something like this

$faker->addProvider(new Faker\Provider\pt_BR\Person($faker));

Just before return [] and then use specific providers, like (in this case) $faker->cpf;

Tested on Laravel 5.3
