I want a push notification system here. How can I implement this in Django? -

Django: Access images via templates, stored on AWS S3
To keep performance I outsourced a machine learning task to AWS Lambda. The result are images saved in an S3 bucket. My challenge is now: How can I access these images through my .html templates? My framework is Django. <img src="s3://BUCKET_NAME/188.png" alt=""> So far I only get access denied. I could make the file public, but my initial goal was to only let my page access these files. Is there a simple solution to grant access without setting up S3Storage (I already have that, but I use a separate account for this machine learning task). -

Django save aggregation in master/detail (many to one relationship)?
I have two models, Order and OrderRow (1:n). What I would like is when something changes on the OrderRow (added, removed, price change, etc.) that that "effect" is calculated to the parent Order. In this case, sum the total of all the OrderRow in Order. The OrderRow (a admin.TabularInline subclass) is setup as inlines on Order. I did implement the django.db.models.signals.post_save but the problem here is that the Order post_save is fired before the OrderRow updates. Is there any nice way (besides implementing a db trigger) for updating this the 'django-way' ? All this under Django Admin -

How can I generate a rest viewset for all child models based on a parent model

Can this be done within standard django rest? -
Why do i get an error when creating a charge with Stripe API in django?

Angular: differentiate between sessions in different tabs
I'm developing a web application. The front end is with Angular and back-end is a Rest API with django rest framework. For some customer requirements, I need that the django rest api is able to differentiate between polling requests with a sessionid. After some searches I found that I can identify the session in the REST API side with the value of: request.session.session_key But that isn't the best choice, because for two different tabs I get the same session_key and the desired sessionId that the rest api receives in the request should identify session for specific tab. So not sessionid for different PCs and host IP address, or browsers only, but also it should get two different sessionids for two different tabs. Does django request object contain other id to identify host tabs? I guess that the solution can be found in Angular side. Is there a way in Angular and typescript to identify tabs sessions? -
Django annotation with multiple rows in Subquery , is it possible?
I have a a question regarding annotation. Firstly, I have 2 related models, that are used in annotation subquery. Secondary model. class UserBriefcaseAttribute(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='user_briefcase_attributes') briefcase_attribute = models.ForeignKey( BriefcaseAttribute, on_delete=models.CASCADE, related_name='+' ) amount = models.IntegerField(default=0) and primary mode for this one class BriefcaseAttribute(models.Model): code = models.CharField(max_length=45) display_name = models.CharField(max_length=45) basically I want to do something like this: SomeModel.objects.filter(**filtering).annotate( result = Subquery(UserBriefcaseAttribute.objects.filter(user=self.request.user, briefcase_attribute__code__in=('silver', 'gold', 'black')).values(‘amount’)) ) Obviously, it doesn't work as subquery returns 3 rows instead of one. I dont know how to deal with it, tried a lot of things already. Expected result should be something like: {‘silver’: 30, ‘gold’: 20, ‘black’: 8} for example or any structure that would be possible to use in DRF serializer Dictfield, or JsonField or Lisfiled or any appropriate field that would be able to render pairs of code: amount (read_only=True). It is possible to do it in separate query but I would prefer to do it via annotation somehow to have only one query. Thanks. -
