Issue with Datetime from database and Django
I'm trying to generate some basic chart data, but I cannot, yet anyways. Whenever I retrieve datetime values from Django models, it gives me this output: [print(i) for i in UserAnalyticsMeta.objects.all().values('created_at')[:3]] {'created_at': datetime.datetime(2022, 8, 15, 22, 43, 23, 88381, tzinfo=datetime.timezone.utc)} {'created_at': datetime.datetime(2022, 8, 15, 22, 48, 43, 944993, tzinfo=datetime.timezone.utc)} {'created_at': datetime.datetime(2022, 8, 15, 22, 48, 49, 95255, tzinfo=datetime.timezone.utc)} Which translates to: 2022-08-15 22:43:23.088381+00:00 2022-08-15 22:48:43.944993+00:00 2022-08-15 22:48:49.095255+00:00 However, when I try to print out the date, this is the output I get: [print(i) for i in UserAnalyticsMeta.objects.all().values('created_at__date')[:3]] {'created_at__date': None} {'created_at__date': None} {'created_at__date': None} While I expect: 2022-08-15 2022-08-15 2022-08-15 What I've also noticed is that an old function I used also doesn't work anymore, and I feel like it has something to do with this. select_data = {"date_created": """strftime('%%m/%%d/%%Y', created_at)"""} qs = self.extra(select=select_data).values('date_created').annotate(models.Sum("page_visits")) return qs Now gives me the error: OperationalError at /admin/app_name/model_name/ (1305, 'FUNCTION app_name.strftime does not exist') Any help would be appreciated! Thank you. -
Django: assigning employees to the hotel rooms and manage dates overlaping and intersection
Task: Imagine we are a company and we want to send our employees on different work trips. Amount of employees for each trip can vary. Also, we are booking hotel rooms for each trip. The room type and max amount of employees per room can be one of these: [{"type": "single", "max_persons": 1}, {"type": "double", "max_persons": 2}, {"type": "triple", "max_persons": 3}, {"type": "quad", "max_persons": 4}] Employees can split the room if room is double, triple or quad Also, employees can live only few days in a row and then next employee could take this room. The task is to get list of dates when room is completely free (no employees lives there) and list of dates when room is partly free (there are 1-3 free beds) Image with visual task explanation The Django models.py is: class Hotels(models.Model): """ Model to store all hotels """ name = models.CharField(max_length=255) phone = PhoneNumberField(blank=True) address = models.CharField(max_length=255, blank=True) city = models.CharField(max_length=255, blank=True) country = CountryField(blank=True) zip = models.CharField(max_length=255, blank=True) REQUIRED_FIELDS = ["name", "address", "city", "country"] def __str__(self) -> str: return self.name class Meta: ordering = ["name"] verbose_name = "Hotel" verbose_name_plural = "Hotels" class RoomTypes(models.Model): """ Model to store all room types """ type = … -

How to execute javascript code after htmx makes an ajax request?
Im currently building a website with django and htmx and i like the combination so far. Lets say I use an htmx attribute on a button to replace a div in the DOM with another div that is supposed to contain a wysiwyg editor. Now the wysiwyg editor has to be initialized with javascript. How do I do this? Can I just return the script tag under the editor div that is being requested with htmx? Wouldnt that be also a little ugly or bad practice because youd have script tags in the middle of the html body? Whats the best way of solving this? Thanks in advance -

Django sync to async
I have this json file below, I wrote a code to check weather a username exists in these sites or not using request library the problem is that it takes too much time and it returns this error.

Django - Redirect Unauthenticated User trying to access UpdateView to DetailView
This is my last brain cell speaking. I have a model called Post with title, body, author, logo and pub_date fields. There is a page in my app that the user can Update/Edit the post. I want the user to be redirected to the Post's Detail page if they tried to access it without being logged in. The problem is that I can't reference the Post's pk to redirect the user to the related page, If I want to put it simply: the user trying to access .../2/edit/ will be redirected to .../2/ if they aren't logged in I Tried using LoginRequiredMixin to block the user but I can't redirect the user to the relative details page. urls.py: urlpatterns = [ path('', PostListView.as_view(), name='index'), path('<int:pk>/', PostDetailView.as_view(), name='details'), path('new/', PostCreateView.as_view(), name='new_post'), path('<int:pk>/edit', PostUpdateView.as_view(), name='update_post'), ] views.py: class PostUpdateView(LoginRequiredMixin, UpdateView): model = Post login_url = reverse_lazy('details', args=[self.object.pk,]) form_class = PostUpdateForm template_name = "posts/update_post.html" I also tried: class PostUpdateView(LoginRequiredMixin, UpdateView): def get_login_url(self) -> str: super().get_login_url() UpdateView.get(self, self.request) self.login_url = reverse_lazy('details', args=[self.object.pk,]) model = Post form_class = PostUpdateForm template_name = "posts/update_post.html" But it returns an empty/none value Is LoginRequiredMixin even the right way to do this?

Limit the choices of a choice field in the model class
This SO answer shows how to limit a choice field in the form. However, I have a choice field with options that should never be shown to the user.

how to declare a serializer field containing list of ids in django

Separate Django permissions per group per user's companies
I have a CustomUser model, each user could be linked to multiple companies. I have initiated my application with 3 generic Django groups; viewer, editor, and supervisor and each user could be a member in only one group. Permissions I have used some global Django permissions like the {app_label}.add_{class_name} permisison with the editor group for an instance. In parallel, I used also django-guardian to have some object-level permissions to get deeper with my objects' permissions as they vary depending on some of the object attributes' values. So, at the end of the day, each user (depending on his group) has some global permissions and some object-level permissions. It works fine that way with no problem so far. Problem As stated earlier, each user is linked to multiple companies. Additionally, each object in my database is linked to a specific company. So, I need to have a higher level of permissions so that each user can deal and interact ONLY with the objects that are linked to one of his companies weather he/she is a viewer, editor, or supervisor. Proposed solutions Those are the solutions that I thought about, but each one of them has some drawbacks and I don't prefer … -

django signals - reverse lookup
I have 2 models Product and ProductComponent. What I am trying to do is to copy the user's id from Product model to all components that are related to this product in ProductComponent model. Let's say that we have a user with id=1. We also have a product with id=3 that contains 3 components. Right now when a user adds a product to the cart it adds the user only to the Product model. What I want is to add user to ProductComponent automatically so if user adds a product to the cart then it will add the user's id to all components that are related to this product in the ProductComponent model. In SQL what should happen when user adds product to cart is something like this: product_id user_id 3 1 productcomponent_id user_id 1 1 2 1 3 1 For now, I need to manually add each component even if I added product to cart. I want to automate it so adding product to cart will be also adding users's id to all components related to this product.
