I am having some trouble designing API endpoint for my Django App (DRF)

More efficient way to update multiple model objects each with unique values
I am looking for a more efficient way to update a bunch of model objects. Every night I have background jobs creating 'NCAABGame' objects from an API once the scores are final. In the morning I have to update all the fields in the model with the stats that the API did not provide. As of right now I get the stats formatted from an excel file and I copy and paste each update and run it like this: NCAABGame.objects.filter( name__name='San Francisco', updated=False).update( field_goals=38, field_goal_attempts=55, three_points=11, three_point_attempts=24, ... ) The other day there were 183 games, most days between 20-30 so it can be very timely doing it this way. I've looked into bulk_update and a few other things but I can't really find a solution. I'm sure there is something simple that I'm just not seeing. I appreciate any ideas or solutions you can offer. -

Django: Issue displaying updates for a MultipleChoiceField, template keeps displaying initial values
First post, apologies in advance for errors. My problem: I initialize my model fields from a proprietary db. These fields are displayed correctly in my template (I can see the html reflects the values in my proprietary db). I then change the initial selection options (for the MultiSelectField) in my template, and save these changed options to the Django db (verified its saved via the admin function) via post overloading in my views. My success_url is setup in urls.py to redisplay the same view. I have overloaded get_context_data in views to load the form data from the Django database, and to update context data with this loaded data, the idea being that when the templates redisplays, my form should now displays the from data loaded from the Django db (not the initial values). What's happening, though, is that the initial values seems to be displayed, as opposed to the changed values I have loaded from the Django db. I would really appreciate help wrt understanding why the template displays values other than what I have loaded from the Django db. my models.py: class LiquidAssetModel(models.Model): #Get my initial values from an external db unq_assets = Jnance_base_data_main.get_unq_assets() init_values = Jnance_base_data_main.get_liq_indexes() liq_dates = … -

I want to redirect a user to checkout page that is automatically generated by the payment gateway. Anytime a user submits a request, the payment gateway returns a response in the format below. What i want to do is redirect the user to the checkout page to make payment. "status": true, "message": "Authorization URL created", "data": { "authorization_url": "https://checkout.paystack.com/eddno1f6rf411p0", "access_code": "eddno1f6rf411p0", "reference": "bpozkels2v" def paystack(request): url = 'https://api.paystack.co/transaction/initialize' transaction_id = random.randint(100000000000, 999999999999) data = { "key": "PUBLIC_KEY", "ref": transaction_id, "amount": "000000000100", "callback": f"http://127.0.0.1:8000", "email": "email@me.com", } headers = { 'Content-Type': 'application/json', 'Authorization': 'Bearer SECRET_KEY', 'Cache-Control': 'no-cache' } res = requests.post(url, data=json.dumps(data), headers=headers) response_data = res.json() print(response_data["authorization_url"]) redirect(response_data["authorization_url"]) The error i get is KeyError at /paystack 'authorization_url' -
SSL certificates and https for AWS hosted django site
I have a django site hosted on elastic beanstalk. I have obtained a AWS SSL certificate and this has been associated with the load balancer 443 HTTPS port. In my config file I have: MIDDLEWARE = [ ... "django.middleware.csrf.CsrfViewMiddleware", ] CSRF_COOKIE_HTTPONLY = False SESSION_COOKIE_HTTPONLY = True With this setup I am able to login to the site but the browser displays 'not secure' in the address bar, and if I prepend 'https://' to the urls I get a page stating the connection is not private. If I add SESSION_COOKIE_SECURE = True CSRF_COOKIE_SECURE = True Then it becomes impossible to login (the login page just reloads) or if I got to a incognito browser I get a 'CSRF verification failed. Request aborted.' message. It may be related but I am also receiving emails stating 'Invalid HTTP_HOST header: ’52.XX.X.XXX’. You may need to add ’52.XX.X.XXX’ to ALLOWED_HOSTS. The ip address relates to one of the ec2 instances running the site but my understanding was that only the address for the elastic beanstalk environment and my domain name needed to be added here. Apologies for the log question, I've just tried to include ay detail that may be relevant -
