{ needs_verification: false }
elsif params[:admin]
{ User.roles.name => 'admin' }
else
{ needs_verification: true }
end)

eltiare / copy-to-s3.rb
Created November 22, 2012 18:34
Multithreaded file copying to S3 via Fog and JRuby
#!/usr/bin/env jruby
# Usage:
# Save this file to /usr/local/bin/copy-to-s3.rb
# You'll want to chmod +x this file to use it on the command line (Linux/OS X: chmod +x /usr/local/bin/copy-to-s3.rb)
# If you're having trouble using JRuby, check out RVM (https://rvm.io/)
# Install the fog gem: gem install fog (after running rvm use jruby, if required)
# This only works if the environment variable JRUBY_OPTS=--1.8. e.g.: export JRUBY_OPTS=--1.8 (Linux/OS X)
# You'll have to edit the options in the file at the top to match your S3 settings.
