This question is for anyone who has experience with the Ruby Gem Shrine for File Uploads.
I am trying to scan file uploads for viruses using ClamAV. The scan works well however the file is already auto uploaded to cloud storage by Shrine prior to validation.
- Is there a hook/callback in Shrine we can use to run the scan prior to file is uploaded?
- Is there are an alternative approach?
Here is the code at the moment.
Attacher.validate do
if file
tmp_file = file.download
# raise Services::Clamav::Client::FileContainVirus
errors << "virus file" if Services::Clamav::Client.virus?(tmp_file.path)
end
end
Any thoughts/answers will help. Thank you.
