activerecord to write to database

I created a db with rake migrate and added to columns, symbol and
cur_price in a table call Financials. I want to use activererecord from
a script to write the data from the script to the database. Could
someone please provide an example.

class Financials < ActiveRecord::Base
  attr_accessible :symbol, :cur_price

Ruby Script parameters:

symbols = [ 'csco","c","bac"

cur_prices = ['10','20','30']

Thanks in advance
