Beginner Django: How to order a queryset by a property
I have a model: class Project(models.Model): title = models.CharField("Project title", max_length=128) start_date = models.DateField("Project start date", blank=True, null=True) end_date = models.DateField("Project end date", blank=True, null=True) @property def has_ended(self): return self.end_date is not None and self.end_date < timezone.now().date() And I want to order projects by two fields: start_date (desc) and also show projects that have not ended first. I know I can't ordery by a property, so I tried the following solution: class ProjectViewSet(viewsets.ModelViewSet): queryset = Project.objects.all().order_by("-start_date") queryset = sorted(queryset, key=lambda a: a.has_ended) serializer_class = ProjectSerializer permission_classes = [permissions.IsAuthenticated] which is the one that has already been answered on other posts with this question. However, I still get the following error: AttributeError: 'list' object has no attribute 'model' I also tried using Django annotations like this: queryset = Project.objects.annotate(has_ended=F('start_date')-F('end_date')).order_by('has_ended', '-start_date') But server returns this error: File "/usr/local/lib/python3.8/site-packages/django/db/models/query.py", line 78, in __iter__ django_1 | setattr(obj, attr_name, row[col_pos]) django_1 | AttributeError: can't set attribute I ran out of ideas on how to achieve the behavior I want. Can someone please give me a hand on that? -

I am working on a small university project. And I want to add voting to my app. I've decided to use django-vote for it.

Django : use @property in success_url KO . while using it with get_success_url is OK (class based view)
I found a workaround for my issue but I need to know why the first above case doesn't work. I need to pass a parameter (reman_pk) to my view but when I try : class RepairCreateView(LoginRequiredMixin, CreateView): @property def reman_pk(self): return int(self.kwargs['reman_pk']) [...] success_url = reverse_lazy( 'reman:update-reman', kwargs={'pk': reman_pk}) [...] ... I got an error django.urls.exceptions.NoReverseMatch: Reverse for 'update-reman' with keyword arguments '{'pk': <property object at 0x10c20bbd0>}' not found. 1 pattern(s) tried: ['reman/update/(?P[0-9]+)/$'] But when in the same class based view I use : def get_success_url(self, **kwargs): if kwargs != None: return reverse_lazy('reman:update-reman', kwargs={'pk': self.reman_pk}) ... it's OK : an int is well passed in my URL. I tried to pass int(reman_pk) in the first method ... not better. I've already use @property in the past and always got a value (int/str) and not property object. -

How to send form data in POST request in Nuxt 3 to django DRF
I am trying to use Nuxt 3 as a server to pass through API requests. I would like to make FormData requests to a Django DRF API through my Nuxt server to POST data and images. basically, the usecase is filling a simple form with data and images and send the formdata to a django backend.

Django annotate with dynamic value
Hi in my model i have property that fully is in cache, not in database class Model(models.Model): .... @property def _get_last_seen_cache_name(self) -> str: return f'{self.hostname.upper()}_last_seen' @property def last_seen(self) -> datetime | None: cached = cache.get(self._get_last_seen_cache_name, None) if isinstance(cached, datetime): return cached return None def update_last_seen(self) -> None: cache.set(self._get_last_seen_cache_name, get_now().replace(microsecond=0), None) How can i annotate with this value last_seen queryset. Want use sorting on this column in admin page. But for this, i need get values from cache on annotation, execute cache.get() with proper key name. Something like this, not working example: queryset = super().get_queryset(request) queryset = queryset.annotate(last_seen=Value(cache.get(Concat('hostname', Value('_last_seen')))), CharField())) or queryset = queryset.annotate(last_seen=Value(cache.get(f"{F('hostname')_last_seen}")), CharField())) I can annotate with literal value, but how annotate with dynamic value, that doesnt exist in database, but in cache or in memory only?

Correct Django serializer implementation for many to many field
I have two django models that are related with a many to many field: class Member(models.Model): user = models.OneToOneField(to=settings.AUTH_USER_MODEL) date_of_birth = models.DateField() bio = models.TextField() class Book(models.Model): name = models.CharField(max_length=255) author= models.CharField(max_length=255) description = models.TextField() read_by = models.ManyToManyField(to=Member, related_name='books_read') The serializers for these models are: class MemberSerializer(serializers.Model): id = serializers.IntegerField(read_only=True) user_id = serializers.IntegerField(read_only=True) class Meta: model = Member fields = ['id', 'user_id', 'date_of_birth', 'bio'] class BookSerializer(serializers.Model): id = serializers.IntegerField(read_only=True) class Meta: model = Book fields = ['id', 'name', 'author', 'bio'] I want to create an endpoint to be able to add a book to a member. The only way I could write a serializer for it was: class BookIdSerializer(serializers.Model): class Meta: model = Book fields = ['id'] def update(self, **kwargs): # logic to add book with passed id to the authenticated user's member profile This however feels very wrong for two obvious reasons: 1 - There is an entire serializer object just to receive a book id 2 - It is not even generic because it performs a very specific function of adding a book with passed book id to a member I am sure there is a better way of doing this. Kindly guide me if you know. -

Django Wagtail dynamic Menu's based on User and User Role
Using Django-Wagtail and Wagtail Menu's. I want to build a system with the following types of characteristics. I have a class of user (Vendor, Supplier) Each created user would need to be one of these two classes. Each class of user has different roles and the roles differ from class to class. e.g. Vendor: finance, stock, admin Supplier: finance, stock, admin, driver. What I have done is create a class called UserType and both "Vendor" & "Supplier" inherit from this class. Then added a field to the User class that selects which type of user they are. class UserType(model.Model): common fields....... class Vendor(UserType): child_vendor_only_fields..... class Supplier(UserType): child_supplier_only_fields..... class User(AbstractUser): userVar = models.ForeignKey(UserType, on_delete=models.SET_NULL, null=True, blank=True) I have also used the wagtail admin to create custom roles for each of these classes as described above. Clearly what "Vendors" can create, read, update and delete varies from that of a "Supplier". And still within that what the finance role can do within the "Vendor" differs from what "Stock" can do. How would I create a dynamic menu that displays different menu's for these permutations? My initial thoughts were inspired by this. Simply adding a choicefield USER_TYPE_CHOICES = ( ('Vendor', 'Vendor'), ('Supplier', 'Suplier')) … -

I am trying to unit test a custom test runner using unittest framework but I get this error. File "/usr/local/lib/python3.7/dist-packages/django/test/runner.py", line 466, in setup_test_environment setup_test_environment(debug=self.debug_mode) File "/usr/local/lib/python3.7/dist-packages/django/test/utils.py", line 111, in setup_test_environment "setup_test_environment() was already called and can't be called " RuntimeError: setup_test_environment() was already called and can't be called again without first calling teardown_test_environment(). I understand that this error message is pretty self explanatory but the problem with running teardown_test_environment within the unit test ends up in this error message File "/usr/local/lib/python3.7/dist-packages/django/test/runner.py", line 588, in teardown_test_environment teardown_test_environment() File "/usr/local/lib/python3.7/dist-packages/django/test/utils.py", line 144, in teardown_test_environment saved_data = _TestState.saved_data AttributeError: type object '_TestState' has no attribute 'saved_data' Has anyone encountered something like this before?
