Missing docs for translated nested modules

i had problems with translated nested slugs: even if they work as intended the child will always take the parent component in the default language in the slug. After a lot of fiddling and reverse enginnering i came with a solution: https://twillcms.com/docs/modules/nested-modules.html#content-working-with-self-nested-items Original code:

class PageController extends NestedModuleController
{
    //...
 
    protected function form(?int $id, TwillModelContract $item = null): array
    {
        $item = $this->repository->getById($id, $this->formWith, $this->formWithCount);
 
        $this->permalinkBase = $item->ancestorsSlug;
 
        return parent::form($id, $item);
    }
}

class PageController extends NestedModuleController
{
    //...
 
    protected function form(?int $id, TwillModelContract $item = null): array
    {
        $item = $this->repository->getById($id, $this->formWith, $this->formWithCount);
 
        $this->permalinkBase = $item->ancestorsSlug;
 
        return parent::form($id, $item);
    }
}

This code will only return the parent slug in only one language so it does NOT work as intended; to fix it we need to implement the getLocalizedPermalinkBase() function that does not have an item. To fix it i came with this solution:

class PageController extends NestedModuleController
{
    //...
    /// we will store localized slugs here:
    protected array $localizedPermalinkBase = [];
    protected function form(?int $id, ?TwillModelContract $item = null): array
    {
        $item = $this->repository->getById($id, $this->formWith, $this->formWithCount);

        ///default locale ancestor slug
        $this->permalinkBase = $item->ancestorsSlug;
        ///multiple locale ancestor slugs
        $locales = config('translatable.locales');
        $this->localizedPermalinkBase = [];
        foreach (config('translatable.locales') as $locale) {
            $this->localizedPermalinkBase[$locale] = $item->getAncestorsSlug($locale);
        }

        return parent::form($id, $item);
    }
    protected function getLocalizedPermalinkBase(): array
    {
        /// this function is called on parent::form so we should be safe
        return $this->localizedPermalinkBase;
    }
}

class PageController extends NestedModuleController
{
    //...
    /// we will store localized slugs here:
    protected array $localizedPermalinkBase = [];
    protected function form(?int $id, ?TwillModelContract $item = null): array
    {
        $item = $this->repository->getById($id, $this->formWith, $this->formWithCount);

        ///default locale ancestor slug
        $this->permalinkBase = $item->ancestorsSlug;
        ///multiple locale ancestor slugs
        $locales = config('translatable.locales');
        $this->localizedPermalinkBase = [];
        foreach (config('translatable.locales') as $locale) {
            $this->localizedPermalinkBase[$locale] = $item->getAncestorsSlug($locale);
        }

        return parent::form($id, $item);
    }
    protected function getLocalizedPermalinkBase(): array
    {
        /// this function is called on parent::form so we should be safe
        return $this->localizedPermalinkBase;
    }
}

If you have a more elegant solution or wnat to update the documentation please do so.

Furthermore if you translated the path you should also consider adding the permalinkBase

class PageController extends NestedModuleController
{
    //...

    protected function form(?int $id, ?TwillModelContract $item = null): array
    {
        $item = $this->repository->getById($id, $this->formWith, $this->formWithCount);

        ///default locale ancestor slug
        $this->permalinkBase = $item->ancestorsSlug;
        ///multiple locale ancestor slugs
        $locales = config('translatable.locales');
        $this->localizedPermalinkBase = [];
        foreach (config('translatable.locales') as $locale) {
            $baseFolder = \Lang::get('routes.articles', [], $locale);///or whatever your translation is called
            $slug = $item->getAncestorsSlug($locale);

            $this->localizedPermalinkBase[$locale] = $baseFolder . ($slug != '' ? '/' : '') . $slug;
        }

        return parent::form($id, $item);
    }

)

class PageController extends NestedModuleController
{
    //...

    protected function form(?int $id, ?TwillModelContract $item = null): array
    {
        $item = $this->repository->getById($id, $this->formWith, $this->formWithCount);

        ///default locale ancestor slug
        $this->permalinkBase = $item->ancestorsSlug;
        ///multiple locale ancestor slugs
        $locales = config('translatable.locales');
        $this->localizedPermalinkBase = [];
        foreach (config('translatable.locales') as $locale) {
            $baseFolder = \Lang::get('routes.articles', [], $locale);///or whatever your translation is called
            $slug = $item->getAncestorsSlug($locale);

            $this->localizedPermalinkBase[$locale] = $baseFolder . ($slug != '' ? '/' : '') . $slug;
        }

        return parent::form($id, $item);
    }

)

Note: using setPermalinkBase on setupController was ignored and overridden
