Created December 30, 2011 23:58
A 'super' method for backbone.js (plain javascript)
// This method gives you an easier way of calling super
// when you're using Backbone in plain javascript.
// It lets you avoid writing the constructor's name multiple
// times. You still have to specify the name of the method.
//
// So instead of having to write:
//
// User = Backbone.Model.extend({
// save: function(attrs) {
// this.beforeSave(attrs);

Created October 26, 2010 11:36
Quick and dirty one off migration task for paperclip plugin to move files from local filesystem to Amazon S3.
# First configure your models to use Amazon s3 as storage option and setup the associated S3 config.
# Then add the classes your want to migrate in the klasses array below.
# Then run rake paperclip_migration:migrate_to_s3
# Should work but this is untested and may need some tweaking - but it did the job for me.
namespace :paperclip_migration do
desc "migrate files from filesystem to s3"
task :migrate_to_s3 => :environment do
klasses = [:model_1, :model_2] # Replace with your real model names. If anyone wants to this could be picked up from args or from configuration.
klasses.each do |klass_key|
