Do you have any news about a releasing date? =)

Yes, but here is the official package: it is out now: https://github.com/tightenco/parental

Thanks

I got thislink from https://m.habr.com/ru/post/344728/ and I dont understand getName(){which things must be here?}

Found this snippet to be still be useful in 2024, thanks!

The tightenco/parental package requires adding a type column to the parent, and I'm only utilising the extention of models as shortcuts for global scopes (with concepts that can overlap), so it felt a bit overkill/incompatible for my usecase

Also I believe an improvement can be made, instead of overriding joiningTable() can just override joiningTableSegment() (which joiningTable() now uses internally)

public function joiningTableSegment()
{
    return Str::snake(class_basename($this->getParentClass()));
}
