Strict None Paginator

Define a strict_none paginator. Nothing when offset > 0

Avoids possibly infinite pagination bugs

JSONAPI.configure do |config|
  config.default_paginator = :offset

  # NOTE: If we're not going to show the number, be sure
  # to use the paginator :strict_none
  config.top_level_links_include_pagination = false
end

app/models/strict_none_paginator.rb

# frozen_string_literal: true

# Usage in resource:
#   paginator :strict_none
#
require 'jsonapi/paginator'
class StrictNonePaginator < OffsetPaginator
  # attr_reader :limit, :offset

  def self.requires_record_count
    false
  end

  def apply(relation, _order_options)
    if @offset > 0
      relation.respond_to?(:none, true) ? relation.none : []
    else
      relation
    end
  end
end
