I'm having an issue where the contents of an uploaded file, via a FileField, are lost when the user resubmits form. I'm guessing the easy answer is to force the user to re-upload the file however I was wondering if there might be a workaround that can avoid having the user re-upload.
Flask-WTF File contents lost when form fails validation and user resubmits form
