Do I need to always have a server running to make every command after starting an app?
I'am reading a book Python Crash Course 2nd Edition 3rd project, creating a django web app. It's said that to start an app I need to have the server running in other terminal tab. In the first tab: python manage.py runserver And in the second tab: python manage.py startapp learning_logs And after these manipulations I need to further do those: defining a model, activating a model, and making migration, etc. Do I need to have a server running to make other commands after starting an app? Or do I only need it running to start an app? So for example, do I need to have server running when further making a migration? python manage.py makemigrations learning_logs -

Module not found error with Django Channels
I'm completely new to using channels, but have tried two separate installations, and setups to just get a basic version of channels running and am encountering a small issue. I'm assuming I'm probably just missing a small thing, but I cannot figure it out. The error is at handshake error I'll also show the current file structure, as well as the files that I've actually made modifications to. asgi.py settings.py settings.py consumers.py consumers.py routing.py Originally, in settings.py having ASGI_APPLICATION set as mysite.asgi.application was resulting in an error so I changed that to mysite.settings and it seemed to work correctly when starting. However, on handshake now this issue occurs, so I feel like that could potentially contribute to it. I've tried on different projects and both encounter this issue. -

How should I serve my API? (authentication without password)
My question on itself isn't a problem in coding, instead I'm having doubts in the design of the user authentication of my API. Sorry if this isn't a question fit for stack overflow I'm developing an API in Django that serves HTML templates. It's going to be served to pages, each one has a set of users. I was planning in following the design described here: Why and when to use API keys So basically, each page will have its own API key, and in order for the users to use the API, the page will request a temporary token for the user. My question is, how could I generate the temporary tokens? Is there a library that deal with this? I had no luck searching. -

How to add global ranking annotation to subsequent Django queries?
I have a Django model that looks like this: class LeaderboardScore(models.Model): score = models.FloatField() player_account = models.ForeignKey(PlayerAccount, on_delete=models.CASCADE) timestamp = models.DateTimeField() This represents top scores in a game. The scores are ranked by score descending and timestamp ascending, so if two scores are the same, the earliest score is ranked higher. Every time I do a query on the leaderboards, I'd like to include the global ranking of each instance in the query result. I can do that successfully when I'm querying all the scores like so: lq = LeaderboardScore.objects.filter(leaderboard__id=1).annotate( rank=Window( expression=DenseRank(), order_by=[F('score').desc(), F('timestamp').asc()] ) ) This will correctly at a rank field with the ranking. But if I take the above query and filter it by player_account like so: # rank will be 1, but should be the global ranking lq.filter(player_account__id=123)[0].rank then the ranking resets so that the first item in the query has the rank of 1, even though its global rank should be different. How do I preserve the global ranking? -

How can I run a kafka consumer in a django project so that messages will passed to django project
I am running my kafka consumer (from the confluent_kafka library) in a separate django management command. (I did this because I couldn't find a way of running a kafka consumer within the runserver process in django without blocking up the runserver process. If there is a better way of doing this I would love to hear suggestions) My projects requirements are: djnago rest api project will receive kafka message for designated topic project will create an instance of model1. creation of model1 will propagate further actions/logic such as creating/updating other models + sending further kafka messages. My issue comes when designing logic to meet my requirements. Requirement 3 can be met using django signals and there is already code that implements these further actions/logic. My problem comes requirement 2 and a bit of 1. My consumer lives in a separate process from my server process so I need to a way of communicating the messages consumed to my server process. What would be the best way of doing this? Using a cache will require another process to read this cache for updates and that leaves me in the same situation as before.
