How to use ActiveRecord none method properly?

I have the following in my controller:

@registrations = Registration.where('id > 1000000000')
Event.unarchived.each do |event|
  event.registrations.by_submitted.each do |reg|
    @registrations << reg
  end
end

There has to be a better way to do this. I've tried replacing the first line with:

@registrations = Registration.none

But when I do that, the final @registrations variable always comes up with zero records.

What is the proper way to use the none method here?

I would recommend you to do it this way:

registration_ids = []
Event.unarchived.each do |event|
  registration_ids << event.registrations.by_submitted.pluck(:id)
end
@registrations = Registration.where(id: registration_ids.flatten)
