Doctrine get repository of all models that extends given abstract class

Question

I have two models: NoteItem and TaskItem . Both extends from AbstractStreamItem :

abstract class AbstractCommentsItem
{
    …
}

class CommentItem extends AbstractCommentsItem
{
    …
}

class TaskItem extends AbstractCommentsItem
{
    …
}

Now I want to get repository of both models in one getRepository command.

Is it possible somehow? I thought about single table inheritance, but not sure if it's the right approach.

Answer 1

Yes, Single Table Inheritance is a valid solution here. You will be able to do:

$entityManager->getRepository(AbstractCommentsItem::class);

to get a single repository for all subtypes.

I'm actually doing that in my current project.
