class PatchedArrayConnection < GraphQL::Pagination::ArrayConnection
  # The default ArrayConnection uses `find_index(item)` which uses `==` to get
  # the index. Unfortunately submission histories are saved through versionable
  # which returns an array of submission histories that all share the same id,
  # and active record overrides the `==` method to check for equality based on
  # said id. When dealing with submissions, change the comparator to look at the
  # submitted_at time (what submission#submission_history is doing) instead of
  # by id so cursors don't break.
  def cursor_for_submission_node(submission)
    submission_idx = items.find_index { |i| i.submitted_at.to_i == submission.submitted_at.to_i }
    idx = submission_idx + 1
    encode(idx.to_s)
  end
