How to add new language dynamically

[camohub]

Hi there,
can somebody tell me please how to achieve this.
I need to add new language to the app dynamically.
There is config/translatable.php which contains

    'locales' => ['en', 'cs', 'cz', 'sk', 'pl',  'de', 'hu',  'uk',  'us', 'gb', ],

This does not allow to add new language which is not defined in this array. I have a controller which want to add new languages and tries to do it this way.

        config([
            'translatable.locales'         => $newLocales,
            'translatable.locale'          => $data['default_language'],
            'translatable.fallback_locale' => $data['default_language'],
        ]);

I thought this will cange the config and library will add new language. But the library allow only the languages which are in config file array.
How can I dynamically add new languages to the application?
Thanks.

Hi, @camohub. It does not work, because the library does not access directly to the configurations and works with the helper class Locales. In general, after setting new locales you need to reload it with method load

config([
    'translatable.locales'         => $newLocales,
    'translatable.locale'          => $data['default_language'],
    'translatable.fallback_locale' => $data['default_language'],
]);

resolve(Locales::class)->load();

You can check how it's works in test suite:

laravel-translatable/tests/LocalesTest.php

Lines 21 to 36 in 0d065da

	public function it_loads_the_locales_from_the_configuration(): void
	{
	$this->app['config']->set('translatable.locales', [
	'de',
	]);
	$this->app->make('translatable.locales')->load();
	self::assertEquals(['de'], $this->app->make('translatable.locales')->all());
	$this->app['config']->set('translatable.locales', [
	'de',
	'en',
	]);
	self::assertEquals(['de'], $this->app->make('translatable.locales')->all());
	$this->app->make('translatable.locales')->load();
	self::assertEquals(['de', 'en'], $this->app->make('translatable.locales')->all());
	}

Thank you very much. It seems it works.
Where in the documentation I can find this?
