No module named settings error django elastic beanstalk
I'm trying to deploy a django app to elastic beanstalk. Beanstalk can't find the settings file when loading wsgi.py. I've seen this in a few other SO questions, but none of those solved my issue. I get the following error: ModuleNotFoundError: No module named 'kairos_app.prod_settings' Target WSGI script '/opt/python/current/app/kairos_app/kairos_app/wsgi.py' cannot be loaded as Python module.

Using python and django to test for reference value
I am someone who is both a doctor and researcher. I want to improve the work process of our department nurses by creating python code (which partly I already made in python) to help most beginning nurses. The issue i can get my head around is trying to link my python code (input) to a webform like in django and for it to return the conditions i have set. Ideally I want to end up for a webpage with a form asking multiple questions (multiple choice), which will return and action for the nurses to perform. I am sorry if this is a very basis and easy question. -

Display success message in Django after download
I am trying to trigger a download of an AWS S3 object using Django 3. views.py def pagelanding(request,slug): if some_condition: URL='URL_to_s3_file' return redirect(URL) So far everything works fine, when I trigger the condition in my template, the download is triggered.
