Django cookies not being saved in Safari nor Firefox
I recently started to test cookies in my development environment as I need it for token storage and csrf token. I came accross the issue of firefox and safari not setting the cookies in their storage tabs. If safari's 'prevent cross-site tracking' is off the behavior is the same with Firefox. However, not all users if any will have this setting off. With the previous mentioned, both browsers do not save the cookies in the storage tab. But, the cookies are received as when I click in an api testing button I have after loggin in, it works and the resources are accessed since cookies are sent. But, neither Safari nor Firefox show it in the cookies tab. Here is the response after log in. Response HTTP/1.1 200 OK Access-Control-Allow-Credentials: true Access-Control-Allow-Origin: https://localhost:3000 Access-Control-Expose-Headers: Content-Type, X-CSRFToken Allow: POST, OPTIONS Connection: close Content-Length: 714 Content-Type: application/json Cross-Origin-Opener-Policy: same-origin Date: Tue, 18 Apr 2023 17:11:05 GMT Referrer-Policy: same-origin Server: Werkzeug/2.2.3 Python/3.9.6 Set-Cookie: auth1=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9; expires=Tue, 18 Apr 2023 17:21:05 GMT; HttpOnly; Max-Age=600; Path=/; SameSite=None; Secure Set-Cookie: csrftoken=Y1GzI80DfRc3lMkUnboTYeA3AZBY4aih; expires=Tue, 16 Apr 2024 17:11:05 GMT; Max-Age=31449600; Path=/; Secure Vary: Accept, Cookie, Origin X-Content-Type-Options: nosniff X-Frame-Options: DENY I am using Django and React both on localhost, … -
my elastic beanstalk application doesn't reflect the latest commit in the live environment
I am deploying my Django app via the eb CLI. I commit my changes to git and deploy (with eb deploy). In the past I would see my changes reflected after a deploy, now I do not. It is as if the application version is being cached on EB's side.Thanks in advance for any help. I checked the source on S3 and it is the latest version, so I have no idea why the live site (also accessed via eb open after deployment to be sure) doesn't reflect. I added some simple console logging to be certain, and it is missing. I've tried restarting the server and rebuilding the environment. Nothing has worked. I also deleted all previous application versions, so the only remaining one has the changes I want, then redeployed and restarted. Still not the version I want running on the environment. -
A form with fields that are associated with different database tables does not pass validation and does not create the necessary record in the db
I need to create an object in a database table using the form. This table is linked to other tables by means of a One-to-Many relationship. that is, through the ForeignKey. The fields are filled in by means of a drop-down list, which displays the objects that are in the tables associated with these fields. When I try to send data from the form, it does not pass validation and does not send anything. forms.py: class receiptForm(ModelForm): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['is_apartment'].empty_label = "Не выбрано" self.fields['is_owner'].empty_label = "Не выбрано" self.fields['is_receipt_type'].empty_label = "Не выбрано" class Meta: model = receipt fields = ['is_apartment', 'is_owner', 'is_receipt_type', 'date', 'receipt_file'] views.py: def create(request): error = '' if request.method == "POST": form = receiptForm(request.POST) if form.is_valid(): form.save() return redirect('main') else: error = "Форма была неверной" form = receiptForm() data = { 'form': form, 'error': error } if (request.GET.get('error')): return render(request, "main/main.html", context={'error': request.GET.get('error')}) return render(request, "main/main.html", data) models.py: class apartment(models.Model): address = models.TextField("Адрес квартиры", max_length=500, default="") def __str__(self): return self.address class owner(models.Model): surname = models.CharField("Фамилия", max_length=50, default="") name = models.CharField("Имя", max_length=50, default="") middle_name = models.CharField("Отчество", max_length=50, default="") email = models.EmailField("Email", max_length=254) def __str__(self): return f'{self.surname} {self.name} {self.middle_name}' class receipt_type(models.Model): pattern = models.FileField("Шаблон", upload_to='pattern') title … -
Testing a Consumer is failing when use database_sync_to_async Djagno Channels
So, I didn't use channels for a very long time, so let's be that this is a first time that I have tried to do something. I am trying to create 1 Consumer, wrapped with 1 custom Auth middleware and I want to test my Consumer, if it behaves properly in various test cases. Django==4.1.7 channels==4.0.0 middleware.py @database_sync_to_async def get_user(email): user = User.objects.get(email=email) if not user.is_active: raise AuthenticationFailed("User is inactive", code="user_inactive") return user class OktaASGIMiddleware(BaseMiddleware): def __init__(self, inner): super().__init__(inner) self.okta_auth = OKTAAuthentication() async def __call__(self, scope, receive, send): try: # token checking and retrieval claims = self.okta_auth.jwt_verifier.parse_token(token)[1] user = await get_user(claims["email"]) scope["user"] = user except Exception as exc: await send({"type": "websocket.close"}) raise return await self.inner(scope, receive, send) tests.py @aioresponses() async def test_connect_with_correct_token_edit_resource_draft( self, mocked_io_request ): mocked_io_request.get( # mocked request/respones ) communicator = WebsocketCommunicator( application, f"/ws/draft/1/?token={sometoken}" ) connected, subprotocol = await communicator.connect() self.assertTrue(connected) So, the issue is, when I use database_sync_to_async as Docs suggests, I am getting: django.db.utils.InterfaceError: connection already closed. When I use from asgiref.sync import sync_to_async, everything works fine and I can test my consumer properly. Also, i an attempt to avoid database_sync_to_async, I switched from JsonWebsocketConsumer to AsyncJsonWebsocketConsumer, but still no help. NOTE: Both of this code works … -

Incrementing an IntegerField in Django
I'm trying to implement the Polls app like the one in the Django documentation. I have an IntegerField to represent the number of votes an option has in my Polls app but if I try to add the voter to the list of voters and increment it by one in my views.py ever time a user votes, it adds to the user to the list of voters but the vote count doesn't increase. This is my Choice model... votes = models.IntegerField(default=0) voters = models.ManyToManyField(UserProfile, blank=True, related_name="my_votes") This is my vote function in views.py option.votes += 1 user = UserProfile.objects.get(user = request.user) option.voters.add(user) How do i fix this please? -
Django: while updating record: ValueError: Cannot force an update in save() with no primary key
There are similar issues on SO, but none alike this. I would like to update a field in a record of a m2m model which has a unique constraint on attendee + training. This model is defined as (model.py): class Occurrence(models.Model): attendee = models.ForeignKey(Attendee, on_delete=models.CASCADE) training = models.ForeignKey(Training, on_delete=models.CASCADE) attended_date = models.DateField(default=date(1900, 12, 31)) class Meta: constraints = [ models.UniqueConstraint(fields=['attendee', 'training'], name='unique_attendee_training') ] Now, consider e.g. that John has taken the Python course and already exists as record in the db. If I try get the date of when the training occurred, I would go like this: from trainings.models import Attendee, Training, Occurrence from datetime import date, datetime attendee = Attendee.objects.get(pk='john@gmail.com') training = Training.objects.get(pk='python310') occurrence = Occurrence.objects.get(attendee=attendee, training=training) print(occurrence.attended_date) # datetime.date(2021, 11, 4) However, if I try to update the date of this record, I get the error. occurrence = Occurrence(attendee=attendee, training=training, attended_date=date(2021, 11, 5)) occurrence.save(update_fields=["attendee", "training", "attended_date"]) The error being: ValueError: Cannot force an update in save() with no primary key. How do I update this record? Note I believe this should be enough to understand the question. But if you want to reproduce the whole issue, I post here the models (model.py) for Attendees and Trainings. class Attendee(models.Model): … -
Python: cannot pickle '_io.BufferedRandom' object [Django] [Cacheops]
I am setting up django cacheops and I am running into an issue regarding pickling my data. My Models have this kind of structure: class A(models.Model): # ... class B(models.Model): link_1 = models.ForeignkeyField(A) link_2 = models.ForeignkeyField(A) link_3 = models.ForeignkeyField(A) def get_link(self): # function does some checks here, decides if link_1, link_2 or link_3 should be loaded link_to_load = "link_1" # fixed for simplicity return getattr(self, link_to_load, None) When I use cacheops, I get this error: cannot pickle '_io.BufferedRandom' object. It also occurs when I use A.object.get(pk=some_pk) instead of getattr. Has someone a tip, how change my code that it does not happen? -

django runserver in http
I'm a little new to django so bear with me. I have an app that's running just fine in HTTPS. In settings.py I have this bit of line that enables it: SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https') SECURE_SSL_REDIRECT = True SESSION_COOKIE_SECURE = True CSRF_COOKIE_SECURE = True Out of curiosity, instead of disabling this every time to test pages and applications, is there a way to enable http for only 127.0.1:8000 and not *.example.com? Or is this a bad practice to even attempt? -

Ordering a QuerySet by the first object in a prefetch_related query
If I have the following models, describing Books which can have several different Titles: class Book(models.Model): publisher = models.CharField(max_length=255) class BookTitle(models.Model): work = models.ForeignKey(Book, related_name="titles", on_delete=models.CASCADE) title = models.CharField(max_length=255) I'm fetching a QuerySet of Books, pre-fetching their BookTitles, like this: from django.db.models import Prefetch books = Book.objects.prefetch_related( Prefetch( "titles", queryset=BookTitle.objects.all() ) ) I'd like to be able to order the QuerySet by the first of the BookTitles. How would I do that? (This is a very simplified example of my actual code to explain the basic question.) -
Django IntegrityError at admin, null value of id violates the not-null constraint
I am fairly new to Django and I use Django 4.2 and PostgreSQL's latest version. I have this issue with my code, I have created models for a blog post.

How to handle errors correctly in django?
I have a question, I know that it is possible to do global exception handling in python, but how to do it for all views, namely, I am interested in DetailView, but others will also come in handy.I understand that you need to give your own examples of solutions, but could you give an example of how this can be done, because I have no ideas at all how to do it. I want to do global error handling so that it can be done like this try: current_profile = Profile.objects.get(user_connected_id=current_user_object) except ObjectDoesNotExist SomeERROR....: logger.info('Object user_connected_id not found....') raise ObjectDoesNotExist And if I don't handle the error that appears, then I want it to work in the global handler. And if it's not difficult: what should I do correctly with errors in this handler, other than logging? I need the DetailView handler most of all -

Invalid JSON error reported whenever a PointField is saved with the GooglePointFieldWidget in the Django admin
I am using Django 4.1 and GooglePointFieldWidget (from django-map-widgets) on PointFields (from django-geojson). The widget gets displayed as it should and I'm able to change the coordinates, set a marker on the map or even type in an address. All good. The problem is that I'm getting a validation error upon saving the object because GooglePointFieldWidget fills in the hidden textarea of the field with invalid JSON, something like POINT (26.2616671966018 65.06716787213769) when Django expects something like {'type': 'Point', 'coordinates': [26.2616671966018, 65.06716787213769]} How can I solve this validation error? -
