Django migration from 3.1 to 3.2 error while copying models instances
I'm trying to upgrade Django from 3.1 to 3.2, and one of the error that I encountered was endpoints that I have that duplicate resources and their related models. In this example: @action( detail=True, methods=['POST'], name='Duplicate one resource', url_name='duplicate', url_path='duplicate', ) @transaction.atomic def duplicate(self, request, pk=None): foo = self.get_object() # gets foo foo_bars = foo.foo_bars.all() # gets a queryset of FooBar new_name = self.append_copy_suffix(foo.name) new_foo = foo.copy_instance(name=new_name) # code below print(foo, new_foo) FooBar.objects.bulk_create( [FooBar(foo=new_foo, bar=foo_bar.bar, stuff=foo_bar.stuff) for foo_bar in foo_bars] ) return Response(self.get_serializer(new_foo).data, status=status.HTTP_201_CREATED) def copy_instance(self, **kwargs): """ Method to copy a model instance More info here: https://docs.djangoproject.com/en/3.1/topics/db/queries/#copying-model-instances :param kwargs: additional parameters to update :return: the duplicated resource """ new_resource = self new_resource.pk = None for k, v in kwargs.items(): setattr(new_resource, k, v) new_resource._state.adding = True new_resource.save() return new_resource This works pretty well in Django 3.1, but in Django 3.2, the related resources are not created for some reason. Things that I noticed in debug and printing the values: When I print the foo and new_foo, they are the same one (new_foo). foo_bars is empty. Maybe because the foo and new_foo are the same one before the bulk_create and the foo_bars is just a queryset that was yet to be … -
ModuleNotFoundError: No module named 'django_invoice'
I get this error every time I try to do migrations or even run my py manage.py runserver. I installed the 'django_invoice' module, inserted it in INSTALLED_APP but still I get the same error over and over again. I installed the requested module hoping that the problem would be fixed but unfortunately it wasn't. -
Can I define an Alias to a foreign field in Django?
I'm looking to define an alias to a foreign key related set so that it can then be used in a generic filtering function. To explain with a little more detail here is a simplified example of my use case demonstrating what I'm trying to achieve: models.py from django.db import models class Family(models.Model): family_name = models.CharField(max_length=100) pets: models.Manager['Pet'] = ... members: models.Manager['Person'] = ... def __str__(self): return f'{self.id} - {self.family_name}' class Pet(models.Model): class PetType(models.TextChoices): CAT = 'cat' DOG = 'dog' LIZARD = 'lizard' name = models.CharField(max_length=100) type = models.CharField(max_length=100, choices=PetType) family = models.ForeignKey(Family, on_delete=models.CASCADE, related_name='pets') def __str__(self): return f'{self.id} - {self.name} {self.family.family_name} [{self.type}]' class Person(models.Model): name = models.CharField(max_length=100) age = models.IntegerField() family = models.ForeignKey(Family, on_delete=models.CASCADE, related_name='members') @property def pets(self) -> models.Manager[Pet]: return self.family.pets def __str__(self): return f'{self.id} - {self.name} {self.family.family_name}' If I have a Person entity, I can use it's pets property to get the pets from the family, what I'm looking for is a way to add an alias/annotation/whatever to a queryset of Person so that I can define: def has_a_cat(query_set): return query_set.filter(pets__type='cat') and then be able to use that for both Family and Person query sets. I know I can filter a Person queryset by the pet type … -
Django-filter with django-table
I've been stuck on this problem for a couple of weeks and can't seem to resolve it through self research. Scenario for testing: I have a 4 learners who are registered against different groups. Using tables2 I've created class GroupListView(SingleTableView), selecting the group takes me to class GroupDetailView(SingleTableView, FilterView). This should show a qs of LearnerInstances associated with that learner. However, when applying the f.qs to the learner queryset it shows all 4 learners on the detail page. views.py class GroupDetailView(SingleTableView, FilterView): table_class = LearnerGroupTable model = LearnerInstance template_name = "learner/group_detail.html" filterset_class = LearnerAimFilter # get all learners within the selected group def get_queryset(self): qs = super().get_queryset() qs = qs.filter( learner__group__slug=self.kwargs["slug"], ) return qs # a queryset of learners within the group from model learnerinstance def get_context_data(self, **kwargs): context = super(GroupDetailView, self).get_context_data(**kwargs) learners = self.get_queryset() context["learners_qs"] = learners f = LearnerAimFilter(self.request.GET, queryset=learners) learners = f.qs context["filter"] = f context["table"] = LearnerGroupTable(learners) context["learners"] = learners context["group"] = Group.objects.filter(slug=self.kwargs["slug"]).values() context["group_name"] = Group.objects.filter(slug=self.kwargs["slug"]).values( "short_name" ) return context If I # out the learners = f.qs the detail view shows the correct learner instances but does not filter.

How to display users who are only included in the Group in django admin panel
I have an Author simple models in my Django project as below: class Author(models.Model): user = models.OneToOneField(CustomUser, on_delete=models.CASCADE, default=None) def __str__(self): return self.user.username note: CustomUser is django's default User model which I added with a phone number In the Group models (in Django admin panel), I have created 'Author' group, to separate or differentiate ordinary users or authors. I want when I enter a new author name in the Author model, the only names that appear are those that belong to the 'Author' group. -

How to paginate ckeditor content in django?
I have ckeditor content as book content. I want to show the content in a fixed width and height container. Instead of scroll. there will be option to navigate pages. Next button and previous button for navigate pages. from django.db import models from django_ckeditor_5.fields import CKEditor5Field class Book(models.Model): title = models.CharField(max_length=255) slug = AutoSlugField(populate_from='title') description = models.TextField() content = CKEditor5Field(config_name="extends") At first I have tried this feature with the default models.TextField(). By counting the words I have splited as pages in javaScript. It was ok but for more text formatting I have to use ckeditor and the ckeditor saves content as html so I can't figure out how I will split the page. Because If I want to split with the previous approch it's possible to miss starting or ending tag in a page. I am using django-ckeditor-5 -

The code works on my network, but not on the university's network
I have a Django server with DRF and custom JWT cookies through middleware. The frontend is built in Next.js and consumes the server routes as an API. Everything works on my machine and network, as well as on some friends' machines who are involved in the project, with the cookies being created and saved correctly. The problem is that this doesn't happen on the university's network, even though it's the same machine (my laptop) and the same browser. At the university, the cookies are not saved, and the error "Cookie 'access_token' has been rejected because it is foreign and does not have the 'Partitioned' attribute" appears. Both codes are on GitHub, and the only thing hosted in the cloud is the database. I am aware of the cookie creation and saving configurations, as well as the CORS policies. I can't figure out where I'm going wrong... Can anyone help me? I can provide the links if possible! Thanks in advance! -

Django Simple JWT + Axios, always getting 401. How can I fix this?
I’m using Nuxt and a pinia store to store the token (the token is present in the store). I've created a plugin for Axios as follows: import axios from "axios"; export default defineNuxtPlugin((NuxtApp) => { axios.defaults.baseURL = "http://127.0.0.1:8000/api/"; axios.defaults.withCredentials = false; axios.defaults.proxyHeaders = false; if (process.client) { let token = window.localStorage.getItem("authTokens"); if (token) { token = JSON.parse(token); console.log(token.access); axios.defaults.headers.common["Authorization"] = `Bearer ${token.access}`; } } return { provide: { axios: axios, }, }; }); The endpoint in Django REST Framework is defined like this: class CreateEvent(CreateAPIView): permission_classes = [IsAuthenticated] serializer_class = CreateEventSerializer def post(self, request, *args, **kwargs): data = request.data.copy() z = request.META.get('HTTP_AUTHORIZATION') data['creator'] = request.user print(request.user, '--------------------') data['types'] = get_type_by_int(request.data.get('type', None)) serializer = self.get_serializer(data=data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) The method I use to call this endpoint is as follows: async sendEvent(): Promise<void> { try { const { $axios } = useNuxtApp(); const response = await $axios.post("event/create/", { latitiude: this.latitiude, longitude: this.longitude, description: this.description, type: this.type, }); console.log("Event sent:", response.data); } catch (error) { console.error("Error while sending event"); } } No matter what I do, I keep receiving a 401 error with the message: Authentication credentials were not provided.

Django: No tables found in the database after running migrations
I'm working on a Django project, but I'm facing an issue where no tables are being created in my database even after running migrations. Django version:5.1.3 Database:MySQL OS:ubuntu 24.04.1 LTS 1 I ran python manage.py makemigrations, and it successfully generated migration files 2 I ran python manage.py migrate, and it executed without any errors. 3 However, when I check the database in phpmyadmin, No tables found in database. I also tried these troubleshooting steps: 1 Verified that the database file exists. 2 Ensured that the INSTALLED_APPS list includes my app. 3 Checked that the models are defined properly in the models.py file. 4 Looked for migration history with python manage.py showmigrations, and all migrations are marked as applied. What could be causing this issue? Are there any additional steps I can take to debug or resolve this problem? I’d appreciate any guidance or suggestions. Let me know if more information is needed. -

The code looks as follows: import grpc from concurrent import futures from scholarly_person_master_service.sp_master_ri_proto_lib.src.main.proto.hello_pb2 import HelloReply, HelloRequest from scholarly_person_master_service.sp_master_ri_proto_lib.src.main.proto.hello_pb2_grpc import SimpleServicer, add_SimpleServicer_to_server # Implementing the service class SimpleService(SimpleServicer): def SayHello(self, request, context): # This method handles the gRPC call and returns a response response = HelloReply(message=f"Hello, {request.name}!") return response # Running the gRPC server def serve(): server = grpc.server(futures.ThreadPoolExecutor(max_workers=10)) add_SimpleServicer_to_server(SimpleService(), server) # Registering the service server.add_insecure_port('[::]:50051') server.start() print("Server started on port 50051") server.wait_for_termination() if __name__ == '__main__': serve() However, when I try to run the server, I encounter an error related to the imports (HelloRequest and HelloReply), even though other imports in the script are working fine. hello_pb2.py File The hello_pb2.py file looks like … -

Django 5.1 UserCreationForm won't allow empty passwords
I am upgrading a Django 3.0 app to 5.1 and have been moving slowly through each minor release. So far so good. However, once I upgraded from Django 5.0 to 5.1, I saw changed behavior on my "Create New User" page, which used to allow empty passwords, with a random password being generated if none is supplied. Now, I can no longer submit an empty password. I get a "required field" error on both the password fields, even though the fields are both explicitly set as required=False. I know there were some changes (5.1.0, 5.1.1) to the UserCreationForm class in Django 5.1. I tried using AdminUserCreationForm instead of UserCreationForm and setting the usable_password field to None, but it still won't allow empty passwords like before. Any ideas? Environment Python 3.12.8 Django 5.1.5 Simplified Code class SignupForm(AdminUserCreationForm): # previously using UserCreationForm usable_password = None # Newly added # Form fields sharedaccountflag = forms.ChoiceField( label='Cuenta compartida', required=True, choices=BOOLEAN_CHOICES ) # Constructor def __init__(self, *args, **kwargs): # Call base class constructor (i.e. SignupForm) super(SignupForm, self).__init__(*args, **kwargs) # Set password fields as optional self.fields['password1'].required=False self.fields['password2'].required=False # Set form helper properties self.helper = FormHelper() setFormHelper(self.helper) # set form method (POST / GET) and styling self.helper.form_tag … -
Using sessions in post requests django
I am currently trying to code my first website. I have a post request taking in answers from a form. I then try to save this information into the session and this doesn’t seem possible. Even when just editing the session data inside the request it doesn’t seem possible and I also can’t print to debug, this could be a stupid question as I am very inexperienced but I cannot find any solution or a reason why? -
Saving "last seen" time doesn't work beyond a few seconds
Based on this question I added the following middleware to track users' last seen date: from datetime import datetime, timedelta from dateutil.parser import parse from .models import User class LastSeenMiddleware: def __init__(self, get_response): self.get_response = get_response def __call__(self, request): last_seen = request.session.get("last-seen") now = datetime.now() too_old_time = now - timedelta(seconds=60) if not last_seen or parse(last_seen) < too_old_time: if request.user.is_authenticated: User.objects.filter(id=request.user.id).update(last_seen=now) request.session["last-seen"] = now.isoformat() return self.get_response(request) This works when I set the timedelta to only a few seconds, but anything more and it stops updating the field. Am I missing something obvious? -
Setting up Django in a subdirectory
I am trying to set up Django in a subdirectory (running under Apache2 through wsgi), but Django stops recognizing the static URLs. This is an example url, that gives me a 404: https:/<domain>/<subdirectory>/<appname>/en/static//img/favicon.png This should map to the filesystem here: /<projectpath>/<appname>/static/<appname>/img/favicon.png The development server (without a subdirectory) finds the file in the filesystem here: /<appname>/static/<appname>/img/favicon.png How do I setup django to recognize it's not running at / but at /<subdomain>/?
