Issue when migrating from SQLite to PostgreSQL in Django
I'm trying to migrate from SQLite to PostgreSQL. "makemigrations" works fine, but when I run the "migrate" command, everything gets complicated. Hello, I'm new to using Django, and I'm encountering the following error when trying to migrate from SQLite to PostgreSQL with an new database image 1 When I started the development of the project, I used fields like TimeField in my model. I'm attaching a snippet from my 0001_initial.py. image 2 Later, I realized that I should use time values differently and decided to modify the model to make them of type FloatField. Snippet from my migrations file 0004_alter_test_time_human_and_more.py image 3 I believe I understand that the issue is when I run the 'migrate' command, Django goes through all migration files, and that's where the conflict with PostgreSQL arises. Has anyone faced the same issue? Any help would be greatly appreciated. -

Understanding TTFB Latency in DJango - Seems absurdly slow after DB optimizations even locally
Our team has been undergoing optimizing our Django DRF / Graphene stack for latency we can't quite understand the source of our slowdowns Our Stack: Python 3.11 Django 4.2.8 DRF 3.14.0 Django Graphene 3.1.5 We've done the 'basic' optimizations of implementing prefetch / select related removed all n+1 generated SQL queries And of course, scrounged the internet looking for answers, and saw the ModelSerializer issue posted here: https://hakibenita.com/django-rest-framework-slow Which as I understand it is 'mostly' fixed in the latest Django? We've manually optimized our QuerySets . SQL, and got our worst case SQL latency is around 200ms, most in the 10-100 range. However, our TTFB, is anywhere from 1 to 3 seconds as measured in dev tools on a browser performing a graphiQL query, as well as in our test suites Here are some numbers from GraphiQL Console: One GQL QUery generates 6 optimzied SQL Queries resulting in a response of a 1.4 MB JSon file which has a heavy amount of nested of elements (necessary for our workload) Django Debug Toolbar numbers: 101.9ms for SQL access Chrome Dev Tools 6 SQL Querues 56.44 ms (not sure how it knows this?) 44us to send request 937 ms waiting for server … -

Problems with CSRF token in django REST Framework integration with React
I'm doing a website using Django REST Framework as a backend with session authentication, React in the frontend and django-cors-headers to comunicate between the two. Each is served in the same IP adress but in different ports. I've implemented an authentication system using SessionAuthentication and the User model from django. The problem is that when I do post requests to the backend it always returns error 403 although the cors headers config seems to be correct and the csrftoken and X-CSRFToken are included in the headers. Here a part of the frontend responsible for the api calls: import axios from 'axios'; axios.defaults.xsrfCookieName = 'csrftoken'; axios.defaults.xsrfHeaderName = 'x-csrftoken'; axios.defaults.withCredentials = true; export const client = axios.create({ baseURL: "http://127.0.0.1:8000" }); export const Register = (credentials) => { return client.post('/api/register', credentials) } export const Login = (credentials) => { return client.post('/api/login', credentials, {'withCredentials': true}) } And the views.py: @method_decorator(csrf_protect, name='dispatch') class UserRegister(APIView): permission_classes = (permissions.AllowAny,) #authentication_classes = (SessionAuthentication,) def post(self, request): clean_data = custom_validation(request.data) serializer = UserRegistrationSerializer(data=clean_data) if serializer.is_valid(raise_exception=True): user = serializer.create(clean_data) if user: return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(status=status.HTTP_400_BAD_REQUEST) @method_decorator(csrf_protect, name='dispatch') class UserLogin(APIView): permission_classes = (permissions.AllowAny,) #authentication_classes = (SessionAuthentication,) def post(self, request): data = request.data assert validate_username(data) assert validate_password(data) serializer = UserLoginSerializer(data=data) if … -

Django - 'NoneType' object is not iterable
I have reviewed my code quite a bit and can't understand why this isn't working. My Products have a Category Model to put products in a specific category. I have sorting on the website to link to specific categories. I created a similar model for Special Offers so I can apply a sub category (special offers) and have a product appear either under the original category and the special offer category. Yet even with an identical configuration, just different variable names, I keep getting 'NoneType' object is not iterable. Any ideas what I'm doing wrong? views.py def all_products(request): """ A view to show all products, including sorting and search queries """ products = Product.objects.all() query = None categories = None sort = None direction = None special_offers = None if request.GET: if 'sort' in request.GET: sortkey = request.GET['sort'] sort = sortkey if sortkey == 'name': sortkey = 'lower_name' products = products.annotate(lower_name=Lower('name')) if sortkey == 'category': sortkey = 'category__name' if sortkey == 'special_offers': sortkey = 'special_offers__name' if 'direction' in request.GET: direction = request.GET['direction'] if direction == 'desc': sortkey = f'-{sortkey}' products = products.order_by(sortkey) if 'category' in request.GET: categories = request.GET['category'].split(',') products = products.filter(category__name__in=categories) categories = Category.objects.filter(name__in=categories) if 'special_offers' in request.GET: speical_offers … -

403 Error while uploading file to Azure Blob via Django app, retrieving html output
I'm a student. This is my first time working with Azure or Django in this capacity, so please bear with me. This is for a final project due in a few days. I did not expect app deployment to be so incredibly complicated! I have written a series of Python files that accept an xlsx file via a form, compare the data of that xlsx file to an API, and then generate an html report of the results. The html is stored on an Azure blob and the link is then provided to the user for download. All of this works when I run the app locally (including the Azure blob connection). When I deploy to Azure, the app runs, but blocks the upload of the xlsx file and a nondescript 403 error is returned. I am not really sure what to try next. Sorry if I'm not providing the correct amount of detail, but happy to discuss further. I'll include more details about packages, etc. below Python Packages: Django pandas azure-storage-blob jinja2 requests Other standard Django dependencies I have tried the following to remedy this so far (I am going insane.): -Environment Variables: Configured necessary environment variables in Azure … -
How can I retrieve the Aerodrone model name and code field values correctly?
I'm working on a Django project with two models, Aerodrone and Meteo. I defined a foreign key in the Meteo model to reference the Aerodrone model. However, the foreign key fields in the database are named aerodrone_id and code_aerodrone_id. I want to retrieve the values of the name and aerodrone_code fields from the Aerodrone model in the Meteo model. I wrote the admin part but the code_aerodrone field always retrieves the values of the name field instead of code. Help me solve this problem. Here is the code: class Aerodrone(models.Model): nom = models.CharField(verbose_name="Nom de l'aérodrone", max_length = 150, unique=True) code = models.CharField(verbose_name="Code de l'aérodrone", max_length = 50, unique=True) class Meta: verbose_name_plural = "Aérodromes" def str(self): return self.nom class Meteo(models.Model): id_message = models.ForeignKey(Idmessage,verbose_name="Id du message", on_delete=models.CASCADE) aerodrone = models.ForeignKey(Aerodrone,verbose_name="Nom de l'aérodromes", on_delete=models.CASCADE, to_field="nom", related_name = "meteo_aerodrone_nom") code_aerodrone = models.ForeignKey(Aerodrone,verbose_name="Code de l’aérodromes", on_delete=models.CASCADE, to_field="code", related_name = "meteo_aerodrone_code") id_station = models.CharField(verbose_name="Code de la station", max_length = 50) date_heure = models.DateTimeField(auto_now_add=True, verbose_name="Date et heure") direction_vent = models.CharField(verbose_name="Direction et la force du vent", max_length = 150) visibilite = models.CharField(verbose_name="Visibilité horizontale", max_length = 150) temps_significat = models.CharField(verbose_name="Temps significatif", max_length = 150) nuages_significatif = models.CharField(verbose_name="Nuages significatif", max_length = 150) temperature = models.CharField(verbose_name="Température de l’air sec et du … -

my home page i.e "/" is listing all the room names with links, which should redirect to that particular room with that name.

Should I list the contestants according to the selected division?
I'm new to web development and I use the Django framework! I ask you to help or guide me on the right path. It is necessary to implement a selection of contestants according to the division selected from the drop-down list. The contestant model has a secondary key to the division model, the template implements the output of two forms: class divisionForm(ModelForm): # Подразделения class Meta: model = division fields = ['name_division'] widgets = { "name_division": Select(attrs={}), } class contestantForm(ModelForm): # Конкурсанты class Meta: model = contestant fields = ['name_contestant'] widgets = { "name_contestant": Select(attrs={}), } enter image description here As far as I understand, Django acts as a server and when the page loads, it returns the data processed in views.py how to implement the withdrawal of all contestants from the selected division in the template? already on the client side without POST and GET requests. Do you have a javascript example for interacting with Django on a similar topic? -
Concatenate 2 RawQuerySets Django
so i have each entity their and they are from legacy system, thats why i cannot perform migration. For example : Entity1 Blog Entity1 Entry Entity2 Blog Entity2 Entry There are 9 entities, means 18 tables So here is my view.py but i cannot do entity1_data.union(entity2_data). How can i merge these, so i can present it in 1 table? Ps: i would try union SQL, but theres too long. entity1_data = BlogModel.objects.using("bcdb").raw("SELECT blog.id as id, blog.name," + "entry.title, " + "entry.date " + "FROM [Entity1 Blog] as blog " + "INNER JOIN [Entity1 Entry] as entry " + "on blog.id = entry.blog_id") entity2_data = BlogModel.objects.using("bcdb").raw("SELECT blog.id as id, blog.name," + "entry.title, " + "entry.date " + "FROM [Entity2 Blog] as blog " + "INNER JOIN [Entity2 Entry] as entry " + "on blog.id = entry.blog_id") I hope i can do it dynamically using dict of tables name. Merged table | Blog ID | Blog Name | Entry Title | Entry Date | | ------------------ | -------------------- | ---------------------- | --------------------- | | [Entity 1 Blog].ID | [Entity 1 Blog].name | [Entity 1 Entry].title | [Entity 1 Entry].date | | [Entity 2 Blog].ID | [Entity 2 Blog].name | [Entity 2 Entry].title …
