CSV Into ActiveRecord

My CSV file (obyek.csv) is look like:
"title","description","latitude","longitude"

And my table structure is:

create_table  byeks do |t|
   t.column :title,	:string, :limit => 40
   t.column :description, :text
   t.column :latitude, :decimal, :precision => 20, :scale => 17
   t.column :longitude, :decimal, :precision => 20, :scale => 17
   t.column :created_at, :datetime
   t.column :updated_at, :datetime
   t.column :created_by, :integer
   t.column :updated_by, :integer
end

From my rails directory
$ ruby script/console
>>require 'csv'
>>o = CSV.readlines('obyek.csv')
>>i = 0
>>while (i < o.length)
>>Obyek.create(:title => o[i][0], :description => o[i][1], :latitude => o[i][2], :longitude => o[i][3])
>>i += 1
>>end
