You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: concern.rb
    path of file: ./repos/tiny_filter/lib/tiny_filter
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module TinyFilter
  module Concern
    class << self
      def included(other)
        if defined?(ActiveRecord::Base) && other <= ActiveRecord::Base
          other.scope :filter_by, ->(args = {}) { TinyFilter::FilterFinder.find(self).f
    
      def included(other)
        if defined?(ActiveRecord::Base) && other <= ActiveRecord::Base
          other.scope :filter_by, ->(args = {}) { TinyFilter::FilterFinder.find(self).filter(self, args) }
        elsif defined?(Sequel::Model) && other <= Sequel::Model
          other.dataset_module do
            def filter_by(args = {})
              TinyFilter::FilterFinder.find(self).filter(self, args)
            end
          end
        else
          raise Error, "unable to include TinyFilter::Concern in #{other} " \
            "that is not an ActiveRecord::Base or Sequel::Model descendant"
        end
