old rails 2 rake task to dump db data into YAML files

fx.rake

namespace :generate do
  desc "Overwrite all fixture files with the contents of all existing tables"
  task :all => :environment do 
    tables = ActiveRecord::Base.connection.tables
    tables.each do |table_name|
      if not table_name == "schema_migrations"
        File.open("db/seed_fixtures/#{table_name}.yml", 'w') do |file|          
          data = ActiveRecord::Base.connection.select_all("SELECT * FROM #{table_name}")
          rows = {}

          data.each do |record|
            fixture_name = record['symbolic_name'].blank? ? 
              "#{table_name}_#{record['id']}" : 
              record['symbolic_name'].downcase
            rows[fixture_name] = record
          end

          file.write rows.to_yaml
        end
      end
    end      
  end
end
