Static Files and Upload, process, and download in Django
I've made a desktop app in Python to process .xls files with openpyxl, tkinter and other stuff. Now i'm looking to run this App on www.pythonanywhere.com. I was expecting to make an app to upload the file to the server, process it and then retrieve it changed to the user. But after long months struggling with Django i`ve reached the problem of static media. As I understood Django doesn’t serve files in production mode. Does this means that I can’t upload-process-download as I was planning? Or I can run in the view function the process algorithm on the request.file and then retrieve it changed, regardless of not serving static files? Am I missing something? Does Flask has the same issue? What’s the optimal solution? Apologize me for the many doubts. PD: I took the time to read many similar questions and seems to be possible to upload and download, but then im missing something on handling static files and what that means -

Using SweetAlert2 in Django
I'm using SweetAlert to have better javascript alerts. In the documentation of sweetalert, says this: A HTML description for the popup. [Security] SweetAlert2 does NOT sanitize this parameter. It is the developer's responsibility to escape any user input when using the html option, so XSS attacks would be prevented. I know that Django autoescapes by default to prevent XSS attacks. My question is if django autoescapes automatically the HTML written by javascript. -
