Rails 7 -- scope for associated records

Question

There are answers for this, but not for Rails 7 which I think added a better way to do this:

Answer model: `belongs to :question`
Question Model: `has_many :answers`

Then, in Question Model:

  scope :answered, -> { where.associated(:answers) } #1
  scope :unanswered, -> { includes(:answers).where(answers: {id: nil})} #2

I found the first one, where.associated(:answers). But I believe theres a better way to do the second one, that is analogous to the first one. But I can't find or get that to work.

Answer 1

from here it looks as if the syntax is:

scope :unanswered, -> { where.missing(:answers) }
