I tried to look up but can only find documents related to count() by group. Hope someone can help me what i need to create this custom query :) -

Difficulty adding slug to Generic Detail View in Django

Django Rest Framework: Prevent duplicate objects when using CreateModelMixin
I have a Viewset where a user can create reviews for a specific product and list their all the reviews they have created for all products: class ProductReviewViewset(CreateModelMixin, ListModelMixin, GenericViewSet): serializer_class = ProductReviewSerializer def get_queryset(self): # Return all reviews for user that are not marked as deleted user = self.request.user return ProductReview.objects.filter(user=user, deleted=False).order_by('review__name') def perform_create(self, serializer): # Add user to review object before saving user = self.request.user serializer.save(user=self.request.user) The problem is that this allows the user to create multiple reviews for the same object. I wanted to prevent this, and only allow to create a review if there is no other review already created for that product (reviews marked as "deleted" will not be counted). So far I was able to override the .create() method and do the serialization, validation and checking for duplicates in there. class ProductReviewViewset(CreateModelMixin, ListModelMixin, GenericViewSet): serializer_class = ProductReviewSerializer def get_queryset(self): # Return all reviews for user that are not marked as deleted user = self.request.user return ProductReview.objects.filter(user=user, deleted=False).order_by('review__name') def create(self, request, *args, **kwargs): # Override create method to prevent duplicate object creation serializer = ProductReviewSerializer(data=self.request.data) serializer.is_valid(raise_exception=True) user = self.request.user product = serializer.validated_data['product'] exists = ProductReview.objects.filter(user=user, product=product, deleted=False).exists() if not exists: serializer.save(user=user) return Response(status=status.HTTP_201_CREATED) else: return … -
No user matches given query even though the user exists
I'm fairly new to Django and am working on making user profile pages accessible by using the user's username in the url, e.g. mysite.com/profile/someusername I'll be having links to the profile in a couple places, but the first place I'm experimenting on is in my navbar to access the logged-in user's page. base.html <a class="dropdown-item" href="{% url 'fillups:user_profile' username=user.username %}" class="btn btn-simple">Overview</a> This correctly displays the currently logged-in user's name, for the case of this example we'll user the username seconduser This is the url pattern I'm using for this: path('profile/<str:username>/',views.UserProfile.as_view(),name='user_profile') So far, the navbar will display the username, seconduser, and when I click the button I'm brought to the url /profile/seconduser/, which is what I want. The problem is, I'm not able to now use the username in my view to query the objects for the given user. Here is what I have for this view so far views.py class UserProfile(TemplateView): template_name = 'fillups/user_profile.html' slug_field = "username" slug_url_kwarg = "username" def get_context_data(self, **kwargs): context = super(UserProfile, self).get_context_data(**kwargs) usr = get_object_or_404(User, username=self.kwargs.get("username")) overview_stats = { 'total_cars': Car.objects.filter(username=usr).count(), 'total_fillups': Fillup.objects.filter(username=self.request.user).count(), 'total_distance': Fillup.objects.filter(username=self.request.user).aggregate(Sum('trip_distance')), 'total_gallons': Fillup.objects.filter(username=self.request.user).aggregate(total_gallons = Round(Sum('gallons'),4)), 'avg_price': Fillup.objects.filter(username=self.request.user).aggregate(avg_price = Round(Avg('price_per_gallon'),3)), 'total_spent': sum_total_sale(Fillup.objects.filter(username=self.request.user)), 'avg_mpg': avg_mpg(Fillup.objects.filter(username=self.request.user)) } context['stats'] = overview_stats context['active_cars'] = Car.objects.filter(status='Active').filter(username=self.request.user) … -

Django inheritance on model
I'm using DRF and I have what appears to be a design issue with my models: Background: I'm doing a personal project for finance administration, so I have models for SavingsAccount, CreditCard, Incomes (this is really simplified but I think that is enough to see the problem). The problem: In incomes I should be able to track to which account I added the money, but that could be to a savings account or to a credit card, so I made another model with the common attributes for both called Account. I'm using InheritanceManager to make it a little bit easier. from model_utils.managers import InheritanceManager class Account(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) name = models.CharField(max_length=120) balance = models.DecimalField(decimal_places=4, max_digits=12) objects = InheritanceManager() def get_child(self): return Account.objects.get_subclass(pk=self.pk) class SavingsAccount(Account): bank = models.CharField(max_length=120) is_investment = models.BooleanField(default=0) class CreditCard(Account): cut = models.IntegerField() pay = models.IntegerField() bank = models.CharField(max_length=120) credit = models.DecimalField(decimal_places=4, max_digits=12) @property def used(self): return self.credit - self.balance class Income(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) amount = models.DecimalField(decimal_places=4, max_digits=12) account = models.ForeignKey(Account, on_delete=models.PROTECT, related_name="incomes") description = models.TextField() date = models.DateField() with this I'm able to interact with the account with things like: income = Income.objects.select_related("account").first() and then income.account.get_child() to retrieve the SavingsAccount or … -

Django how to debug a frozen save operation on a queryset object

Best way to DRY in create/update model forms in django
How do you manage your model forms for create or updated operations?. I want to look if there is way to respect the DRY django’s philosophy, like one more dynamic ModelForm class or something like that to handle both operations instead of two classes: class EmployeeCreateForm(forms.ModelForm): class Meta: ... class EmoloyeeUpdateForm(forms.ModelForm): .... I use model form factory and instance parameter: Employeeform = model_form_factory() form = EmployeeForm(instance=SomeModel.objects.get....) But what if I want to keep any model pk field as read only during updating (i.e. Employeer id), changing widget fields (i.e. model foreign keys by default shows as html select tag but i want them as character field, that’s why I’m using instance parameter). Actually I achieved this with what i mentioned, creating 2 classes for its related operations and defining widgets with attrs. Thanks. -

Storing multiple strings to a single field in Django model
I am trying to create a simple test program for a site. Basically the user will enter in a large amount of JSON. Then I will parse the JSON and get 10 random properties from the JSON.

Basically I want to keep track of property user_answer correct_answer But I would like to keep it as a single item. -
Many-To-One Using Django Allauth
I am creating a website where teachers can have many students and students can have one teacher. So far I have just been using the default Django Allauth User model. I now want to separate teachers from students and give them relationships. I was thinking I would: Add an is_teacher flag to the default user class (this way I could simply determine if a user is a student or a teacher in my templates). I also think I should be able to add this to my current Allauth User models without causing any problems (doing this should keep my Allauth User models as-is but add the extra is_teacher field shouldnt it?). class User(AbstractUser): is_teacher = models.BooleanField('teacher status', default=False) Create additional student and teacher tables to hold extra data specific to either students or teachers and hold my student-teacher relationships: class Student(models.Model): student = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) teacher= models.OneToManyField(Teacher) extra_field_example = # field to hold students age class Teacher(models.Model): teacher = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) student = models.OneToManyField(Student) extra_field_example = # field to hold teachers current number of students Create a signal which creates a Student profile and attaches it to the user whenever a new user is created (id manually create … -

DRF Django File Upload ModelViewSet: why do we have to override perform_create?
I can't really figure this out. Given this model: class AppRelease(models.Model): name = models.CharField(null=False, max_length=250) file = models.FileField(upload_to=app_release_directory_path, storage=OverwriteStorage(), null=True) In order to achieve a working POST with a file upload, if we want it to work, we have to override perform create and pass the variables in the save method. class AppReleaseViewSet(viewsets.ModelViewSet): queryset = AppRelease.objects.all() serializer_class = AppReleaseSerializer parser_classes = (MultiPartParser, FormParser, JSONParser) def perform_create(self, serializer) -> None: serializer.save(name=self.request.data.get('app_id'), file=self.request.data.get('file')) What I don't understand is, why do we need to override perform_create if we are not really adding any extra data. Why doesn't it work out of the box if the parameters sent are the same? I want to know this, because, even if I know how to make it work, I prefer to reduce the code I write, in order to make everything more readable. And this seems like repeating something just for the sake of it, without adding anything. Is there, maybe, another way of doing it? Thanks for your insight. -

My AJAX is working and I want to know why
