Dump models into fixtures. (See related posts)

This snippet of code will look in app/models for all models, then dump their contents into the corresponding fixture file found in test/fixtures. At the moment, it can not differentiate between regular models and mailer models, so just remove the extension then run the script. Same goes for models you don't want dumped. I'm working on adding only and except as well.

require 'find'

namespace :db do
  namespace :fixtures do
    desc 'Dumps all models into fixtures.'
    task :dump => :environment do
      models = []
      Find.find(RAILS_ROOT + '/app/models') do |path|
        unless File.directory?(path) then models << path.match(/(\w+).rb/)[1] end
      end
  
      puts "Found models: " + models.join(', ')
      
      models.each do |m|
        puts "Dumping model: " + m
        model = m.capitalize.constantize
        entries = model.find(:all, :order => 'id ASC')
        
        formatted, increment, tab = '', 1, '  '
        entries.each do |a|
          formatted += m + '_' + increment.to_s + ':' + "\n"
          increment += 1
          
          a.attributes.each do |column, value|
            formatted += tab
            
            match = value.to_s.match(/\n/)
            if match
              formatted += column + ': |' + "\n"
              
              value.to_a.each do |v|
                formatted += tab + tab + v
              end
            else
              formatted += column + ': ' + value.to_s
            end
            
            formatted += "\n"
          end
                    
          formatted += "\n"
        end
      
        model_file = RAILS_ROOT + '/test/fixtures/' + m.pluralize + '.yml'
        
        File.exists?(model_file) ? File.delete(model_file) : nil
        File.open(model_file, 'w') {|f| f << formatted}
      end
    end
  end
end
