Truncate consecutive values in a Django (TimescaleDB) QuerySet
I have a QuerySet consisting of a timestamp and a boolean value. When there are consecutive repeating values, I'd like to truncate them to only show the first (and maybe the last one too, but not mandatory). e.g. the given queryet <TimescaleQuerySet [ {'time': datetime.datetime(2023, 1, 23, 10, 57, 7, 971506, tzinfo=<UTC>), 'is_on': True}, {'time': datetime.datetime(2023, 1, 23, 10, 53, 11, 787303, tzinfo=<UTC>), 'is_on': True}, {'time': datetime.datetime(2023, 1, 23, 10, 53, 20, 646474, tzinfo=<UTC>), 'is_on': False}, {'time': datetime.datetime(2023, 1, 23, 10, 27, 7, 971506, tzinfo=<UTC>), 'is_on': False}, {'time': datetime.datetime(2023, 1, 23, 10, 23, 20, 646474, tzinfo=<UTC>), 'is_on': False}, {'time': datetime.datetime(2023, 1, 23, 10, 23, 11, 787303, tzinfo=<UTC>), 'is_on': True}, {'time': datetime.datetime(2023, 1, 23, 9, 57, 7, 971506, tzinfo=<UTC>), 'is_on': True}] should truncate to <TimescaleQuerySet [ {'time': datetime.datetime(2023, 1, 23, 10, 57, 7, 971506, tzinfo=<UTC>), 'is_on': True}, {'time': datetime.datetime(2023, 1, 23, 10, 53, 20, 646474, tzinfo=<UTC>), 'is_on': False}, {'time': datetime.datetime(2023, 1, 23, 10, 23, 11, 787303, tzinfo=<UTC>), 'is_on': True}] I'm breaking my head over this. Is there an elegant way to achieve this? I want to avoid looping over the whole queryset, it's just too slow when theres >1000 results. -
custom message if there isnt any record to show in django-template

Unitest DRF with CONTEXT
I am wondering if anyone could help me with the appropriate way to create a unitest in DRF when using context inside a serializer. as you can see in the serializer below, I am adding a field called distance to my serializer. class CompanySerializer(serializers.ModelSerializer): """Serializer for companies.""" distance = serializers.SerializerMethodField() class Meta: model = Company fields = ['id', 'company_name', 'lat', 'long', 'logo', 'distance'] def get_distance(self, company): """Return context""" print(self.context) return self.context['distances'][company.pk] Then when calling the unitest I get an error: KeyError: 'distances' COMPANY_URL = reverse('company:company-list') def test_company_list_limited_to_user(self): """Test list of companies is limited to authenticated user.""" other_user = create_user( email='other@example.com', password='password123' ) create_company(user=other_user) create_company(user=self.user) res = self.client.get(COMPANY_URL) companies = Company.objects.filter(user=self.user) serializer = CompanySerializer(companies, many=True) self.assertEqual(res.status_code, status.HTTP_200_OK) self.assertEqual(res.data, serializer.data) Is there a better way to write this test, so it can pass? I did check and the context distance is create and passed to the serializer with no issue, but the test is not passing :/ Tks a lot! Kind regards Victor Almeida -

Handling form fields in django for logged in user
Im trying to handle the existing name of a Category, so that users wont be allowed to create 2 categories with the same name, but at the moment its taking all categories from the database, not only for the logged-in user.

Django dj-rest-auth (django-allauth) redirection doesn't work, however, LOGIN_REDIRECT_URL is set
I'm using Django 4.1 (Djoser doesn't work with 4.x) and dj-rest-auth (if I'm not mistaken, registration is provided by django-allauth module). What am I trying to achieve is getting new user to a profile creation page ('/api/v1/new_hero/' endpoint), right after he signs up. Without any email verification, just right into it. But for now, with all theese settings, after registration, django keeps the user on the same ('auth/registration/') page with tokens demonstration and other stuff. By the way, situation keeps similar with loginning. How am I supposed to direct the user to a target page? settings.py: DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField' REST_USE_JWT = True JWT_AUTH_COOKIE = 'jwt-auth' SITE_ID = 1 LOGIN_REDIRECT_URL = '/api/v1/new_hero/' ACCOUNT_SIGNUP_REDIRECT_URL = '/api/v1/new_hero/' ACCOUNT_AUTHENTICATED_LOGIN_REDIRECTS = True ACCOUNT_EMAIL_VERIFICATION = 'none' items/urls.py urlpatterns = [ path('items/', ItemsListCreateView.as_view(), name='list_items'), path('items/<int:pk>/', ItemDetailView.as_view(), name='update_item'), path('heroes/', HeroListView.as_view(), name='list_heroes'), path('new_hero/', HeroCreateView.as_view(), name='create_hero'), path('heroes/<int:pk>/', HeroDetailView.as_view(), name='update_hero'), path('classes/', HeroClassListCreateView.as_view(), name='list_classes'), path('weapons/', WeaponClassListCreateView.as_view(), name='list_weapons'), # path('reg/', Registration.as_view(), name='custom_registration'), ] I tryied different django-allauth settings, checked correctness of INSTALLED_APPS, AUTHENTICATION_BACKENDS and other sections of settings.py, and it all end up here, with me writing a question. -
s3 bucket does not collect created pdfs in media folder django/aws
I just deployed my django application to a beanstalk server linked to an s3 bucket in the aws console. In my application pdfs from each post are created and forwarded to the media folder in the subfolder "postings". However, in the bucket no such folder is created and the pdfs also don't show up anywhere else. only the uploaded images of the post is there. How do I get the pdfs there? also, I get an ValueError now for the Image in the PDF (which is the uploaded image, and which was working just fine before adding the bucket). How do I get it to work again? I think both problems are due to some connection missing... This is my first project deploying to aws. Please help me out with a little explanation. Here is the code of the created upload and pdf: views.py def post_create(request): if request.method == 'POST': form = PostCreateForm(request.POST, request.FILES) if form.is_valid(): form.cleaned_data['num_post'] = Post.objects.count() + 1 Post.objects.create(**form.cleaned_data) else: form = PostCreateForm() return render(request, 'index.html', {'form': form}) def upload(request): if request.method == 'POST': image = request.FILES.get('image_upload') caption = request.POST['caption'] num_post = Post.objects.count() + 1 new_post = Post.objects.create(image=image, caption=caption, num_post=num_post) new_post.save() # create pdf buffer = io.BytesIO() … -
Problem with running maintenance mode in my Django and React apps that are stored on Azure Web App for Containers?
I have deployed Django and React application on Azure. I am using Web Application for Containers. One Web App is for Django and second one is for React (CORS headers are properly confiured, both apps are connected to each other). Docker images are stored on Azure Container Registry. I am looking for an option to switch both apps to Maintenance mode when doing some maitenance things or deploying. I was thinking abouting creating extra env variable called MAITENANCE_MODE in Application settings where I can switch manually from false to true and then it switches the mode on websites automatically. Another idea would be to create some webjobs but I am not familiar with these topics and I am asking for an advice on how to do it or at least where to look for such solution. -

Django modeltranslation and AutoSlugField
I'm struggling with combination of AutoSlugField (from django-extensions) and ModelTranslation. class Article(models.Model): title = models.CharField(max_length=255, default="") slug = AutoSlugField( populate_from=[ "title", ], overwrite=True, ) Make perfect sense without model translation. Unfortunately, if title and slug fields are translatable it does not work out of the box. The migration file created by ModelTranslation contains description for AutoSlugField: migrations.AlterField( model_name="article", name="slug_de", field=django_extensions.db.fields.AutoSlugField( blank=True, editable=False, null=True, populate_from=["title"] ), ), migrations.AlterField( model_name="article", name="slug_en", field=django_extensions.db.fields.AutoSlugField( blank=True, editable=False, null=True, populate_from=["title"] ), ), But slug_en should be based on title_en and slug_de should be based on title_de. Is it possible to enforce such behavior? -
