Yes. That is the recommended way (foreign key mapping).
The User object has a property "posts" holding the the related "Post" 
objects. But the Post object has no property like userId (or user_id).

This is not recommended. A possible solution could be to add a property 
"user" to the Post object holding the (single) User object. And then say 
inside your Controller

$post = $this->postRepository->findLatestPost(); // for example
$userPosts = $this->postRepository->findByUser($post->getUser());

In Extbase (and FLOW3) Domain Models are plain PHP classes with no 
(public) magic methods.
