Thanks Mladen Ilic for your reply. I think I am getting closer to the solution I need.
You should be able to access the attachment with > `record.attachment_changes['pv_file']`. > I must be doing something wrong, as I can't figure out how to access the actual file contents/octet-stream. post_body << self.attachment_changes['pv_file'] throws Zlib::Data Error incorrect header check post_body << self.attachment_changes['pv_file'].blob.download throws Aws::S3::Errors::NoSuchKey post_body << self.attachment_changes['pv_file'].blob.open throws ActiveStorage::FileNotFoundError I am sure I am showing my Ruby ignorance here. Any help is appriciated. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.
