How to download multiple files from s3 on fly?

Hi,

I am able to download files from s3 as a zip by using below mentioned code.

require 'open-uri'

def download_all_files
folder_path = "#{Rails.root}/public/downloads/"
zipfile_name = "#{Rails.root}/public/archive.zip"

FileUtils.remove_dir(folder_path) if Dir.exist?(folder_path)
FileUtils.remove_entry(zipfile_name) if File.exist?(zipfile_name)
Dir.mkdir("#{Rails.root}/public/downloads")

@model_object.each do |attachment|
open(folder_path + "#{attachment.avatar.file.filename}", 'wb') do |file|
file << open("#{attachment.avatar.url}").read
end
end

input_filenames = Dir.entries(folder_path).select {|f| !File.directory? f}

Zip::File.open(zipfile_name, Zip::File::CREATE) do |zipfile|
input_filenames.each do |attachment|
zipfile.add(attachment,File.join(folder_path,attachment))
end
end

send_file(File.join("#{Rails.root}/public/", 'archive.zip'), :type => 'application/zip', :filename => "#{Time.now.to_date}.zip")

end

But by using this code, that files are storing in my application. Is there any way to download files directly from s3 or is there a way to remove files which are stored in public folder.

This is a pervasive problem that I still haven't found a solution for.

great

Deleting files in a shared folder, if not done correctly. Then you can specify at once to read files from the directory and delete them.

To download an entire bucket to your local file system, use the AWS CLI sync command, passing it the s3 bucket as a source and a directory on your file system as a destination, e.g. aws s3 sync s3://YOUR_BUCKET . . The sync command recursively copies the contents of the source to the destination
