How to show all company who has photo attachment?

company:

id | name 

user:

id | name | company_id

post:

post_attachment:

id | post_id | path | type

company model:

public function users() {
  return $this->hasMany('App\User')->orderBy('id', 'ASC');
}

user model:

public function posts() {
  return $this->hasMany('App\Post');
}

posts model:

public function images(){
  return $this->hasMany('App\PostsAttachment')->where("type", "image");

I want to get all company who have user(s) that have post(s) with minimal 2 images attachment. Anyone can help me?

I tried Company::has('users.posts.images', '<', 2)->get(); but it also give companies who has user image below 2.

Using eloquent you could write your logic as

$companies = Company::has('users.posts.images')->get();
