A quick and dirty way to download files from s3 to local for development

carrierwave.rb

CarrierWave.configure do |config|

  if Rails.env.development? || Rails.env.test?
    config.storage = :file
  else
    config.storage = :fog
    config.fog_credentials = {
      provider: 'AWS',
      aws_access_key_id: Rails.application.secrets.aws_access_key_id,
      aws_secret_access_key: Rails.application.secrets.aws_secret_access_key
    }
    config.fog_directory = Rails.application.secrets.s3_bucket_name
  end

end

s3_to_local.rb

s3 = "https://***.s3.amazonaws.com"
Post.find_each {|post| (post.remote_logo_url = "#{s3}#{post.logo.url}"; post.save!) if post.logo.blank?   }
