使用对话框使用openpyxl下载/上传Excel工作簿

Question

I'm using Django and Openpyxl to create an app that can write an Excel workbook using data from the app and then save the file locally.

When I used:

wb = Workbook()
wb.save('test.xlsx')

The file was saved in my Django project's root folder.

How can I have the file download to the browser's download folder as opposed to saving directly in the root directory of the app on its server?

Thanks.

openpyxl provides a function to save a file to a StringIO object:

from openpyxl.writer.excel import save_virtual_workbook
stream = save_virtual_workbook(wb)

However, for larger files it might be preferable to save to somewhere in the file system and let the http server handle the download.
