问题 I need to get the path to the file on disk which is using ActiveStorage . The file is stored locally. When I was using paperclip, I used the path method on the attachment which returned the full path. Example: user.avatar.path While looking at the Active Storage Docs, it looked like rails_blob_path would do the trick. After looking at what it returned though, it does not provide the path to the document. Thus, it returns this error: No such file or directory @ rb_sysopen - Background I need
