早些时候我的文件上传到存储文件夹中。但现在我想在 s3 存储桶上上传图像。如何迁移 s3 存储桶上现有的本地数据?
我在这里找到了脚本 https://www.stefanwienert.de/blog/2018/11/05/active-storage-migrate-between-providers-from-local-to-amazon/
但是得到一个错误
NoMethodError (private method `open' called for Active Storage
那么我应该怎么做才能将我的本地数据迁移到 s3 存储桶?
有没有更简单的方法?
最佳答案
嗨,我也遇到了那个错误,我已经将脚本更改为 rake 任务,如下所示:
# frozen_string_literal: true
namespace :active_storage do
desc 'Migrate ActiveStorage files from local to Amazon S3'
task migrate: :environment do
module ActiveStorage
class Downloader
def initialize(blob, tempdir: nil)
@blob = blob
@tempdir = tempdir
end
def download_blob_to_tempfile
open_tempfile do |file|
download_blob_to file
verify_integrity_of file
yield file
end
end
private
attr_reader :blob, :tempdir
def open_tempfile
file = Tempfile.open(["ActiveStorage-#{blob.id}-", blob.filename.extension_with_delimiter], tempdir)
begin
yield file
ensure
file.close!
end
end
def download_blob_to(file)
file.binmode
blob.download { |chunk| file.write(chunk) }
file.flush
file.rewind
end
def verify_integrity_of(file)
raise ActiveStorage::IntegrityError unless Digest::MD5.file(file).base64digest == blob.checksum
end
end
end
module AsDownloadPatch
def open(tempdir: nil, &block)
ActiveStorage::Downloader.new(self, tempdir: tempdir).download_blob_to_tempfile(&block)
end
end
Rails.application.config.to_prepare do
ActiveStorage::Blob.send(:include, AsDownloadPatch)
end
def migrate(from, to)
configs = Rails.configuration.active_storage.service_configurations
from_service = ActiveStorage::Service.configure from, configs
to_service = ActiveStorage::Service.configure to, configs
ActiveStorage::Blob.service = from_service
puts "#{ActiveStorage::Blob.count} Blobs to go..."
ActiveStorage::Blob.find_each do |blob|
print '.'
file = Tempfile.new("file#{Time.now}")
file.binmode
file << blob.download
file.rewind
checksum = blob.checksum
to_service.upload(blob.key, file, checksum: checksum)
rescue Errno::ENOENT
puts 'Rescued by Errno::ENOENT statement.'
next
end
end
migrate(:local, :s3)
end
end
