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: tags.rb
    path of file: ./repos/mastodon/app/models/trends
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

class Trends::Tags < Trends::Base
  PREFIX = 'trend
    
  def request_review
    tags = Tag.where(id: currently_trending_ids(false, -1))

    tags.filter_map do |tag|
      next unless would_be_trending?(tag.id) && !tag.trendable? && tag.requires_review_notification?

      tag.touch(:requested_review_at)
      tag
    end
  end
