I'd like to run a Django app on a linux machine using miniconda as a tool for managing packages and virtual environment. Systemctl will launch gunicorn as a dedicated system user, say my_app_user. Sources will be on /opt/my_app with permission only for my_app_user. What is the correct / secured way to install miniconda for such use case ? -

Use BytesIO instead of NamedTemporaryFile with openpyxl
I understand that with openpyxl>=3.1 function save_virtual_workbook is gone and preferred solution is using NamedTemporaryFile. I want it to be done without writing to filesystem, only in memory, just like BytesIO did. Before update I had: wb = Workbook() populate_workbook(wb) return BytesIO(save_virtual_workbook(wb)) Now I need: wb = Workbook() populate_workbook(wb) tmpfile = NamedTemporaryFile() wb.save(tmpfile.name) return tmpfile As in https://openpyxl.readthedocs.io/en/3.1/tutorial.html?highlight=save#saving-as-a-stream As I'm using django probably I could use InMemoryUploadedFile but I don't want to. How can I use BytesIO or something similar in elegant fashion ie. without hacks and additional packages? -
