S3 で既存または新しく作成されたファイルにテキストを追加する方法。私が使用fog
していて、次のコードがあります
require 'fog'
file = "abc.csv"
bucket = 'my_bucket'
storage = Fog::Storage.new(:provider => 'AWS', :aws_access_key_id => 'XXXXXXXX', :aws_secret_access_key => 'YYYYYYYY')
dir = connection.directories.new(:key => bucket) # no harm, if this bucket already exists, if not create one
buffer = ["big_chunk1", "big_chunk2", "big_chunk3", "big_chunk4", "big_chunk5"]
# I need help after this line. No changes above.
buffer.each do |chunk|
# this will not work as it will not append text below the existing file or
# newly created one. I am not looking for solution suggesting, buffer.join('')
# and then write whole chunk at once. I have to write in chuck for some specific reason.
# Also I dont want to first read existing data and then take in to memory
# and then append and finally write back.
dir.files.create(:key => file, :body => chunk, :public => false)
end
