I need do allow user to download pdf files directly from s3 bucket.
I figured out a method, which works correctly, but I cannot open downloaded files, getting Permission denied.

If I do it from console, everything is fine, and I can open downloaded pdf files afterwards.

Here's my method

 def download_pdf
 pdf_url = @file.pdf_url
 f = open(pdf_url)
 FileUtils.mv(f.path, "#@file.id.pdf")
 end

What can be wrong? I tried to close TempFile, as described here, but it didn't help

  Are the files on S3 public (yes: just use the link and let them download; no: use send_data to access and send)? Are you uploading them there with ActiveStorage to begin with?

  No, they are not. And I don't want to use send_data since I try to avoid streaming

  If you compare the file sizes between what you can pull from the command line and what's saved with your download_pdf function, are they the same?
