Question

I’m trying to insert 200k records into three different tables. When I parse the CSV file and try to insert these records, Ruby locks up my entire system. Here is my code:

def upload_country
  @upload = Upload.new(:upload => params[:upload])
  if  @upload.save
  csv = CSV.parse(csv_text, :headers => true)

  csv.each_with_index do |row, index|
    unless row["name"].blank? or row["country_code"].blank? or row["destination"].blank? or row["code"].blank?
      @country = Country.new(:name => row["name"].gsub(/\s+/, " ").strip, :country_code => row["country_code"].gsub(/\s+/, " ").strip, :user_id => current_user.id, :subscriber_id => get_subscriber_id)
      @country.save

      if row["country_code"] == "1"
        p = @[e-mail]+row["code"].gsub(/\s+/, " ").strip
      else
        p = @country.country_code.to_s+row["code"].gsub(/\s+/, " ").strip
      end

      @code = DestinationCode.create(:code => p, :country_destination_id => 1, :user_id => current_user.id)
    end
  end

  @upload.destroy
  @countries = Country.find_all_by_subscriber_id(get_subscriber_id)
  render :partial => '/mycarriers/carrier_country', :layout => false
end
