Query on User related Object in Django
In my Application I am trying to query a field which in depth requires a reverse lookup. Let me explain by Models Models.py class User(AbstractUser): is_employee = models.BooleanField(default=False) is_client = models.BooleanField(default=False) class Client(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) client_name = models.CharField(max_length=500, default=0) class MaterialRequest(models.Model): owner = models.ForeignKey(User, on_delete=models.CASCADE) flows = models.ManyToManyField(MaterialRequestFlow) is_allocated = models.BooleanField(default=False) class Allotment(models.Model): transaction_no = models.IntegerField(default=0) dispatch_date = models.DateTimeField(default=datetime.now) send_from_warehouse = models.ForeignKey(Warehouse, on_delete=models.CASCADE) sales_order = models.ForeignKey(MaterialRequest, on_delete=models.CASCADE) Now I want to query Allotment which are created by a particular Client. In the frontend I have a dropdown of Clients which sends the id of the Client Here's my function for this: Views.py class AllotmentReport(APIView): permission_classes = (permissions.IsAuthenticated,) def get(self, request, *args, **kwargs): cname = self.kwargs['cname'] if self.kwargs['cname']: items = Allotment.objects.filter(sales_order__owner??? = cname).order_by('-id') #Need Help Here else: items = Allotment.objects.all().order_by('-id') serializer = AReportSerializer(items, many=True) return Response(serializer.data, status=status.HTTP_201_CREATED) Also I'd like to know If there is a better alternative to do that -
How can I sort a list of models considering one element of a many-to-many relation?
We're building an API using Django Rest Framework where I have the following schema: class Main(models.Model): name = models.CharField(default=None, max_length=200, blank=True, null=True) # [...] class Attribute(models.Model): main = models.ForeignKey('Main', on_delete=models.CASCADE, related_name='attrs') code = models.CharField(max_length=50, null=True) value = models.CharField(max_length=50, null=True) I want to build a queryset (paginated) for a list of Main objects and I would like to sort them using the "value" of certain Attribute "code". For example, if we suppose three attributes are: "age" (8-18), "grade" ("A", "B", "C", etc.), "stars" (0-5) and Main were "students" I would like to be able to build a queryset for the list of students ordered by "age" and "grade" values. I've tried something like: queryset = Main.objects.filter(id__in=ids).filter(attrs__code='age').order_by(attrs_value) Extra: Woud I be able to reach a multiple attr order? -

Reducing queries on serialization with SerializerMethodField
I currently have a serializer which uses two SerializerMethodField that access the same nested object, resulting in two db calls: # models.py class Onboarding(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) is_retailer_created = models.BooleanField(default=False) is_complete = models.BooleanField(default=False) # views.py class StateView(RetrieveAPIView): serializer_class = serializers.UserSerialiser def get_object(self): return self.request.user # serializers.py class UserSerialiser(serializers.ModelSerializer): is_onboarded = serializers.SerializerMethodField() is_loyalty_onboarded = serializers.SerializerMethodField() class Meta: model = models.User fields = ('is_onboarded', 'is_loyalty_onboarded') def get_is_onboarded(self, obj): onboarding = obj.onboarding_set.first() if onboarding: return onboarding.is_retailer_created return False def get_is_loyalty_onboarded(self, obj): onboarding = obj.onboarding_set.first() if onboarding: return onboarding.is_complete return False I'd like to roll this into one call if possible. Normally it would be possible to just use prefetch_related, but since the get_object is returning the specific user (and not a queryset) I don't think that solution works here. Is there a way to prefetch the Onboarding model with the user? Or failing that have a single call to Onboarding instead of two? -

How to use VSCODE Live Server with templated html?
I'm a web developer who primarily uses Django and is used to using templatized code with Jinja and what not. The Live Server vscode extension is SUPER valuable, but seems to not be able to work with ANY Templating from what I've researched (actually, I couldn't even find another question, but I'm sure it's out there.) I want to use Live Server without having to copy and paste the stuff in the head tag, or the same navbar / footer over and over and over again. Do I have to choose between having templated HTML and using Live Server? If not, how can I do this with Live Server? For example: base.html <!-- DOCTYPE html --> <html> <head> </head> <body> <main> <!-- Where I want the other page's code to be --> </main> </body> </html> Then with my other html pages, I want to not link the other pages: other_page.html <!-- Between the main tag in the other page --> <div>Added code but on a different page</div> <!-- End of the code --> I'm more than open to using some front-end framework like view or react if this will work with liveserver. Thanks in advance! :) -
