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: statistic_saver.rb
    path of file: ./repos/sparkler/app/models
    
    the code of the file until where you have to start completion: class StatisticSaver
  def initialize(feed)
    @feed = feed
    @properties = Property.all.includes(:options).to_a
  end

  def save_params(params, user_agent)
    params = params.clone

    params.de
    
  def save_params(params, user_agent)
    params = params.clone

    params.delete('appName')
    params.delete('controller')
    params.delete('action')
    params.delete('id')

    date = Date.today
    app_version = user_agent.split(' ').first.split('/').last
    subtype = params.delete('cpusubtype')

    if subtype && params['cputype']
      subtype = "#{params['cputype']}.#{subtype}"
    end
