Last active August 29, 2015 13:56 — forked from louisgillies/paperclip_migration.rake
# 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|
