Hi guys. how do i check birthday of user in background and send a birthday wish to his/her email (even if user is not online on website)? can you guys PLEASE give me a good resource to learn more about this?
you are looking for async tasks. there are many different options on how to do them. for example you can have a cron process running every 24 hours that triggers a management command from django (which goes through users and sends the appropriate emails).
