How to integrate Cognito SSO with Django grapehene
We have an up and running django project that already uses graphene and graphql_jwt (along with django's internal auth). We are attempting to integrate SSO with cognito for this project, but since graphene and graphql_jwt already have their inbuilt auth mechanisms, its becoming hard to make sense of how to integrate Cognito with these. My guess was that I will mostly be needing to only add an authentication backend, that sets the user using the cognito. But this is causing issues with the graphql's existing authentication and it is unable to recognise that the user has already been authenticated. How can the cognito's authentication be added to the existing graphql_jwt flow? -

In Django, how do I construct my queryset to filter by time over slices of time?
I'm using Python 3.9 and Django 3.2. I have this price model class Price(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) price = models.FloatField(null=False) created = models.DateTimeField(null=False, default=datetime.now) If I want to get the price per hour over the last 24 hours, I can run a method like this def _get_prices_per_time_slice(self, last_hours=24): now = timezone.now() end_time = now.replace(second = 0, microsecond = 0) start_time = end_time - timedelta(hours=last_hours) qset = Price.objects.filter( created__range=[start_time, end_time], created__minute=end_time.minute ).values('price') return [r['price'] for r in qset] but let's say I want to get the price every last X hours. def _get_prices_per_time_slice(self, last_hours=24, time_slice_in_hours=4): so if the current time is midnight (and zero seconds and minutes), I would want to get the prices for midnight, 8 pm, 4 pm, noon, 8 am and 4 am. How do I add a filter to screen for prices every X hours? -

Django 3.2 update AutoField to BigAutoField backward compatibility with foreign key relations
I'm running into a problem after updating my project from Django 2.2 to Django 3.2. In Django 2.2 primary keys are created using AutoField meaning in MySql they are considered int(11) and all foreign keys from this table must also be int(11) In Django 3.2 primary keys are now created with BigAutoField which in MySql creates type bigint(20) therefor I can't create any foreign key relations with old tables. According to the documentation this can be changed in settings using DEFAULT_AUTO_FIELD = 'django.db.models.AutoField'. This works in creating primary keys as int(11) however foreign key fields are still being created as bigint(20) meaning a relation can't be created because they must be of the same type. Here says that you can change all your existing tables to BigAutoField but this also doesn't take care of foreign key relations. Is there any way to change all primary keys and their relations to a different type easily? Am I missing something in the Django documentation where they also provide compatibility to related keys and well as primary keys? I would obviously prefer to change all my current data to work with BigAutoField if all future releases of Django will now use this as … -

Where are variables passed into the view in Django?
I'm refactoring code in a Django view. I'm working with a view with the below arguments: def title_views(request, key, group, sort): group = get_object_or_404(Group, group=group, main_id = key) default_sort = sort I know by default each view should have the request argument. But in terms of key, group, sort, where can I expect these items to be passed? Is it through the template that the view is called in? I come here for help because the documentation isn't that clear on this, at least in my experience. Thanks! -
