Help: How to save data of a related model within a Filament form?

I'm trying to make the title of a CourseResource translatable into German and English. However, the translations are not being saved to the course_translations table. How can I handle the saving of fillable attributes that are in another table (relationship between 2 models) ?

public static function form(Form $form): Form
{
    return $form->schema([
        Section::make('English Content')
            ->schema([
                TextInput::make('translations.en.course_title') <-- Here
                    ->label('Course Title')
                    ->required()
                    ->placeholder('Course Title'),
            ]),
        Section::make('German Content')
            ->schema([
                TextInput::make('translations.de.course_title') <-- Here
                    ->label('Course Title')
                    ->required()
                    ->placeholder('Course Title'),
            ]),
        ...
]);

public static function form(Form $form): Form
{
    return $form->schema([
        Section::make('English Content')
            ->schema([
                TextInput::make('translations.en.course_title') <-- Here
                    ->label('Course Title')
                    ->required()
                    ->placeholder('Course Title'),
            ]),
        Section::make('German Content')
            ->schema([
                TextInput::make('translations.de.course_title') <-- Here
                    ->label('Course Title')
                    ->required()
                    ->placeholder('Course Title'),
            ]),
        ...
]);

In the Course model I have this:

public function translations(): HasMany
{
    return $this->hasMany(CourseTranslation::class);
 }

public function translations(): HasMany
{
    return $this->hasMany(CourseTranslation::class);
 }

And in the CourseTranslations this:

public function course(): BelongsTo
{
  return $this->belongsTo(Course::class);
}

public function course(): BelongsTo
{
  return $this->belongsTo(Course::class);
}

Unfortunately Spaties Translatable plugin doesn't suit my needs. :/ The DB tables exist for both both courses and course_translations. Detailed Code with Course Model, CourseTranslation Model and Course Resource: https://gist.github.com/Synistic/b033856ec909badfd09e6573feddb98f

Your missing the relationship on the field. https://filamentphp.com/docs/3.x/forms/fields/repeater#integrating-with-an-eloquent-relationship

Thank you! I managed to setup the repeater. Is it possible to save HasMany relationsships without an repeater? In my case I will always have 2 translations in the repeater, so 2 fixed sections would be better

No you only have relationship managers or repeaters. You can set the repeater to default to only two and not allow more. https://filamentphp.com/docs/3.x/panels/resources/relation-managers#relation-managers---interactive-tables-underneath-your-resource-forms
