Is it possible to remove an item type from a lineitem.aggregate when making a different calculation?
The delivery cost should not include % on booking, but should include % of product price if below the set delivery threshold. Both can be added to an order and at checkout only the product should attract a delivery cost, as the booking relates to buying experiences. I am unable to figure this out, so if anyone can help me I would be most grateful. Below is my model code for checkout, which includes the Order Model where the delivery is being calculated, and Order Line Item Model from where the order total is being calculated using line item aggregate. def update_total(self): """ Updates grand total each time a line item is added, takes into account delivery costs """ self.order_total = self.lineitems.aggregate( Sum('lineitem_total'))['lineitem_total__sum'] or 0 if self.order_total < settings.FREE_DELIVERY_THRESHOLD: self.delivery_cost = self.order_total * \ settings.STANDARD_DELIVERY_PERCENTAGE / 100 else: self.delivery_cost = 0 self.grand_total = self.order_total + self.delivery_cost self.save() class OrderLineItem(models.Model): order = models.ForeignKey( Order, null=False, blank=False, on_delete=models.CASCADE, related_name='lineitems') product = models.ForeignKey(Product, null=True, blank=True, on_delete=models.CASCADE) experience = models.ForeignKey(Experiences, null=True, blank=True, on_delete=models.CASCADE) quantity = models.IntegerField(null=False, blank=False, default=0) lineitem_total = models.DecimalField( max_digits=6, decimal_places=2, null=False, blank=False, editable=False ) price = models.DecimalField( max_digits=6, decimal_places=2, null=False, blank=False,) def get_price(self, *args, **kwargs): if self.product and self.experience: return self.product.price … -
Manager's annotations don't show up when traversing ForeignKey
Suppose I have such classes: class UserManager(Manager): def get_queryset(self): return super().get_queryset().annotate( full_name=Concat( F('first_name'), Value(' '), F('last_name'), output_field=CharField() ) ) class User(Model): first_name = CharField(max_length=16) last_name = CharField(max_length=16) objects = UserManager() class Profile(Model): user = ForeignKey(User, CASCADE, related_name='profiles') And I want to include an annotated field in my query: Profile.objects.filter(GreaterThan(F('user__full_name'), Value(24))) But I got a FieldError: Cannot resolve keyword 'full_name' into field. Choices are: first_name, id, last_name, profiles It's clear that I could repeat my annotation in a current query: Profile.objects.filter(GreaterThan(Concat(F("user__first_name"), Value(" "), F("user__last_name"), output_field=CharField(),), Value(24))) But as soon as my annotations will become more complex, my code become mess. Is there any workaround? -
Cookies not being set in browser when making API request from React, but work with Django REST framework
When I use the Django REST framework to send a POST request to the login endpoint, the cookies are added to the response, and I can observe them in the browser. Additionally, I can confirm that I'm receiving the correct data (user ID and password) in both cases. However, when I use my React application to send the same POST request to the login endpoint, the cookies are not being added to the response, and consequently, they aren't stored in the browser. Again, I receive the correct data (user ID and password) in this scenario as well. My django rest code : @api_view(['POST']) def loginUser(request): print("request", request.data) id_Patient = int(request.data.get('id_Patient')) print("id_Patient", id_Patient) password = request.data.get('password') print("password", password) user = Patient.objects.filter(id_Patient=id_Patient).first() if user is None: print("user is None") return JsonResponse({"message": "User not found"}, status=404) if not user.check_password(password): print("not user.check_password(password)") return JsonResponse({"message": "Incorrect password"}, status=400) payload = { 'id_Patient': user.id_Patient, 'exp': datetime.datetime.utcnow() + datetime.timedelta(minutes=60), 'iat': datetime.datetime.utcnow() } secret_key = os.urandom(32).hex() token = jwt.encode(payload, secret_key, algorithm='HS256') response = JsonResponse({"token": token}) response.set_cookie('my_cookie', 'my_value', httponly=True) # Set the cookie return response What Actually Resulted: Surprisingly, the cookies are being set correctly when I test the API request using Django's REST framework, and I'm receiving the … -

Why Django ORM filter lists all the users?
I like to make a filter where user can search based on last_name or a regio(region). I made the query but it filters well only if I using the last_name filter, but the regio gives all the users in the db.

django layout template tags with async view

Django Migration - User ForeignKey - (errno: 150 "Foreign key constraint is incorrectly formed")
I can't perform a migration for a User foreign key and I've tried everything. This is the model: class Test(TimeStampedModel): key = models.ForeignKey("users.User", on_delete=models.CASCADE) And this is the migration part (settings.AUTH_USER_MODEL is generated by makemigrations): dependencies = [ migrations.swappable_dependency(settings.AUTH_USER_MODEL), ("xxxxx", "xxxxx"), ] operations = [ migrations.CreateModel( name="Test", fields=[ ( "key", models.ForeignKey( on_delete=django.db.models.deletion.CASCADE, to=settings.AUTH_USER_MODEL, ), ), Note that I've tried to set my model variable like this: key = models.ForeignKey(User, on_delete=models.CASCADE) I've also tried to replace settings.AUTH_USER_MODEL by the user class name like: ( "key", models.ForeignKey( on_delete=django.db.models.deletion.CASCADE, to="users.User", ), ), Note also User have been created before the migration, I've checked it with this code: def check_table_exists(apps, schema_editor): if not schema_editor.table_exists('users_user'): raise RuntimeError('users_user must exist!') class Migration(migrations.Migration): dependencies = [...] operations = [ migrations.RunPython(check_table_exists), # Other operations ] Whatever the solution I'm trying I've always the same MySQLdb._exceptions.OperationalError: (1005, 'Can't create table mdc.alerts_alertchanges (errno: 150 "Foreign key constraint is incorrectly formed")') -
How to protect a single database row / Model instance?
We have customers, and Customer objects. One of these, which I was creating with a migration, was Customer( account='INTERNAL' ...) as a placeholder for when we manufacture stuff for internal consumption. Customers come and go, so the objects need to be deletable. But this single row must not be deleted. What is the best way to stop it getting accidentally deleted? I can replace all instances of Customer.objects.get(account='INTERNAL') with get_or_create so it is self-resurrecting, but it feels like storing up trouble for the future if there are ForeignKey references to it and then it gets deleted. (It can't be Models.PROTECT, because other customers can be deleted). Tagged [postgresql], because that's what we use. I suspect there might be a way to use database functionality to do what I want, but I'd appreciate it if the answer showed how to write doing that as a Django migration (if that's possible). I know more about Django than SQL and Postgres extensions. -

Run server is VScode for python/django ecommerce a "type error" pops up?
So basically I'm trying to relearn python with this course where you make a ecommerce website using Django/Python.

What does it mean that serializer validators are good because it makes it easy to switch between Model Serializer and explicit Serializer?
I've been reading the rest_framework document but I'm finding it hard to grasp the meaning of this sentence "It is easy to switch between using shortcut ModelSerializer classes and using explicit Serializer classes. Any validation behavior being used for ModelSerializer is simple to replicate." It's one of the three benefits of using serializer validators but... Why would you switch between ModelSerilzer and Serializer class defined serializers? What does it mean it's easy to replicate? Why would I replicate a validator defined for a ModelSerializer? Here is the link where it's written https://www.django-rest-framework.org/api-guide/validators/ Thank you for checking out this question! I tried looking up for the same question that talks about the replicable advantage of django serializer validators. But All I got was the fact that it's better to create model instance via serializers because serialziers have easy validating logic and that it's better to keep both serialzier validator and model validator. -
Django: dropdown is populated with the id of a ForeignKey, but i would like to populate it with its textual value (and not the id)
In the dropdown I get the campionato id, because I'm selecting a ForeignKey. I would like to populate the dropdown with the textual value of the sampled ForeignKey and not with the id. IMPORTANT: Considering that the two dropdowns are dependent, I had to use campionato of the Full_Record class (and not the one of the Campionato class) I have read several solutions and similar questions, but they didn't help me.
