DRF - overrige Serializer.update to update related set
I'm trying to override update method of ModelSerializer so I can update the related set of objects while updating the instance. The problem is that validated_data doesn't include ids of these objects even when I'm passing there to the serializer. def update(self, instance, validated_data): subcontracts = validated_data.pop('subcontracts') # THERE ARE NO IDS HERE contract = super().update(instance,validated_data) instance.subcontracts.exclude(id__in=[x.get('id',None) for x in subcontracts if x is not None]).delete() for subcontract in subcontracts: _id = subcontract.get('id',None) if _id: sc = SubContract.objects.get(id=_id) else: sc = SubContract() for attr, value in subcontract.items(): setattr(sc, attr, value) sc.contract = instance sc.save() return contract Basically, what I want to do: {id:4, some_data..., subcontracts:[{id:1,description:'xxx'},{id:2,description:'yyy'}]} This data would (except updating the instance) delete related subcontracts not having id 1 or 2 and update the rest. Do you know what to do? -

Django Creating Two Objects If Don't Exist
I have a django app and I need in one view function to get two objects: token and plan or create them if they don't exist, here the code I'm currently using: def get_or_create_token_and_plan(user): try: token = Token.objects.get(user=user) except ObjectDoesNotExist as e: token = Token.objects.create(user=user) try: plan = Plan.objects.create(user=user) except ObjectDoesNotExist as e: plan = Plan.objects.get(user=user) return token, plan def profile(request): user = User.objects.get(username=request.user) token, plan = get_or_create_token_and_plan(user) context = {'token':token, 'plan':plan} return render(request, 'profile.html', context) I'm trying to figure out a way of improving get_or_create_token_and_plan() function, knowing that token and plan objects will be, in theory, created initially at the same time. Except for exceptions, if I merge both try, except structures into a single one will work, like here: def get_or_create_token_and_plan(user): try: token = Token.objects.get(user=user) plan = Plan.objects.create(user=user) except ObjectDoesNotExist as e: token = Token.objects.create(user=user) plan = Plan.objects.get(user=user) return token, plan The main issue with this is that if token already exists and plan doesn't, the I will get an IntegrityError when creating it again for the same user, but as said, in theory this won't happend because both token and plan will be created only in this function, so my question is, should I change get_or_create_token_and_plan in … -

django-allauth no records in db for emailconfirmation but verification works
I've been doing some tests with django allauth, but in production with debug flags off, I'm not able to view any email confirmation records in my db (postgresql) while verification still works correctly... My understanding is that any verification emails sent is recorded in the account_emailconfirmation table in the django's database (I use postgres). I can see these records in the db and in the admin console (as model view) in local testing (with debug on), but in production, both the records and the entry for EmailConfirmation in the admin console itself is missing. Have I messed up my migration settings? What could have caused this? -

ieldError: Unsupported lookup for AutoField or join on the field not permitted
Good day, I am trying to build a system that creates an order and allows a user to add pieces. Here are the two models: class Order(models.Model): order_slug = models.SlugField(unique=True, blank=True) machine = models.ForeignKey(Machine, blank=True,on_delete=models.DO_NOTHING) production_type = models.CharField(choices=PRODUCTION_TYPE_CHOICES, max_length=30) production_bond = models.CharField(choices=PRODUCTION_BOND_CHOICES, max_length=50) profile = models.CharField(choices=PROFILE_CHOICES, max_length=50) order_number = models.CharField(max_length=50) order_colour = models.CharField(choices=ORDER_COLOUR_CHOICES, max_length=50) order_finish = models.CharField(choices=ORDER_FINISH_CHOICES, max_length=10) order_gauge = models.IntegerField(choices=ORDER_GAUGE_CHOICES) order_width = models.IntegerField() date_received = models.DateTimeField(default=datetime.now) class Meta: ordering = ["date_received", "-profile"] def __str__(self): return (str(self.order_slug)) class Piece(models.Model): order = models.ForeignKey(Order,on_delete=models.CASCADE) coil = models.ForeignKey(Cut_Material ,on_delete=models.CASCADE) piece_length = models.DecimalField(max_digits=4, decimal_places=2) prime_pieces = models.IntegerField() reject_pieces = models.IntegerField() coil_constant = models.IntegerField(blank=True) def __str__(self): return (str(self.piece_length)) class Meta: ordering = ["-order","piece_length"] Here is what I want to do. Multiply the prime_pieces by the piece_length to get running_meters for each column I want to group the pieces by order_gauge, order_number, and sum the running_meters. Proposed solution piece = Piece.objects.all() order = Order.objects.all() For step 1 rm_data = Piece.objects.annotate(running_meters=ExpressionWrapper(F('piece_length') * F('prime_pieces'), output_field=FloatField())).values() For step 2 I am not sure Can someone help me please?
