#Looking for the best way to update items in a table in mass below is the best I've come up with but it seems hacky and I've read that update() is depreciated

class Table < ActiveRecord::Base
  
  ...
  
  class << self
  
    def big_update
      items = Table.all
      saves=[]

      items.each do |item|
        item.value = rand(10)
        saves << item.as_json
      end

      saves = Hash[*saves.map{ |p| [p["id"], p] }.flatten]
      self.update(saves.keys, saves.values)
    end
