Use text file to add test data

Hi, Im trying to make an application based on the 'depot' app from 'Agile web development with Rails'. Instead of putting the data in add_test_data.rb itself (p.89), I want to read it in from a txt file like this (gg.txt has a list of front and last names):

class AddTestData < ActiveRecord::Migration     def process(k)     k.chop!     ary = k.split     Zwemmer.create(:lastname => ary[1,3].join(' '), :frontname => ary[0].to_s.downcase, :group => 'gg', :image_url => '/images/ggs.png')   end

  def self.up       Zwemmer.delete_all       myfile =File.new("gg.txt", "r")       myfile.each {|line| process(line)}             myfile.close     end

    def self.down     end end

error: rake aborted! No such file or directory - gg.txt

gg.txt is in the same directory as add_test_data.rb. Where should i put the txt file? How should i read it in?

Rake sets the work directory to the root of the rails app. You're also trying to call an instance method from a class method, which won't work.

Thanks for the speedy reply Fred. I've relocated gg.txt to the right directory, and now a new error pops up, as you have foreseen: Undefined method 'process' ...

What can i do to solve this?

I made process a class method too, now it works..
