My weird way of not rewriting all of the json for to_json and to_indexed_json

model_snippet.rb

# ...
  # Helper Function
  def index_content
    require 'open-uri'
    if self.content.present? && self.content.url.present? && self.content.url.downcase.ends_with?("pdf")
      uri = URI.join HOSTNAME, self.content.url
      io = open(uri)
      reader = PDF::Reader.new(io)
      reader.pages.collect(&:text).join
    end
  end

  # Class level helper function
  def self.index_content(filepath)
    reader = PDF::Reader.new(filepath)
    reader.pages.collect(&:text).join
  end

  #Overwrite as_json which generates the hash for to_json
  def as_json(options={})
    return super(options) if options.include?(:skip)
    default_options = {
      :methods => [:index_content]
    }

    all_options = default_options.merge(options)
    super(all_options)
  end

  #For elasticsearch indexing
  def to_indexed_json
    to_json(methods: [:tag_list]) #For instance if we also want to index the tag_list method
  end
