TypeError at / cannot unpack non-iterable NoneType object (Django)
I'm trying to set up a system on my Django project where users can comment on individual posts on the main (index) page. However, I'm having an issue when it comes to trying to make it so the comment is automatically connected to the post.

Django serializer to convert list of dictionary keys to model fields
I am using pandas openpyxl to read excel file in my project. After reading the excel file I end up with list of dictionaries. These dictionaries have keys such as "Year 2024", "Range", "Main Point", and etc. I have a field in my Django app that has these fields such as "year", "range", "main_point". My question is how can I write a serializer to convert dictionary keys to fields in my model? I want to do this in serializer because I also want to validate dictionary data. So I have this list: my_data = [ {"Year 2024": "5", "Range":"2", "Main Point": "OK"}, {"Year 2024": "6", "Range":"3", "Main Point": "OK"}, {"Year 2024": "7", "Range":"4", "Main Point": "OK"}, ... ] and my model class MyModel(models.Model): year = models.IntegerField(...) range = models.IntegerField(...) main_pont = models.CharField(...)

How to load chat messages in batches in Django using StreamingHttpResponse?
I'm working on a Django project that streams chat messages between two users using StreamingHttpResponse and async functions. I want to load messages in batches (e.g 20 at a time) instead of loading all the messages at once to optimize performance and reduce initial load time. Here’s my current view code: async def stream_chat_messages(request, recipient_id: int) -> StreamingHttpResponse: """View used to stream chat messages between the authenticated user and a specified recipient.""" recipient = await sync_to_async(get_object_or_404)(User, id=recipient_id) async def event_stream(): async for message in get_existing_messages(request.user, recipient): yield message last_id = await get_last_message_id(request.user, recipient) while True: new_messages = ( ChatMessage.objects.filter( Q(sender=request.user, recipient=recipient) | Q(sender=recipient, recipient=request.user), id__gt=last_id, ) .annotate( profile_picture_url=Concat( Value(settings.MEDIA_URL), F("sender__userprofile__profile_picture"), output_field=CharField(), ), is_pinned=Q(pinned_by__in=[request.user]), ) .order_by("created_at") .values( "id", "created_at", "content", "profile_picture_url", "sender__id", "edited", "file", "file_size", "is_pinned", ) ) async for message in new_messages: message["created_at"] = message["created_at"].isoformat() message["content"] = escape(message["content"]) json_message = json.dumps(message, cls=DjangoJSONEncoder) yield f"data: {json_message}\n\n" last_id = message["id"] await asyncio.sleep(0.1) async def get_existing_messages(user, recipient) -> AsyncGenerator: messages = ( ChatMessage.objects.filter( Q(sender=user, recipient=recipient) | Q(sender=recipient, recipient=user) ) .filter( (Q(sender=user) & Q(sender_hidden=False)) | (Q(recipient=user) & Q(recipient_hidden=False)) ) .annotate( profile_picture_url=Concat( Value(settings.MEDIA_URL), F("sender__userprofile__profile_picture"), output_field=CharField(), ), is_pinned=Q(pinned_by__in=[user]), ) .order_by("created_at") .values( "id", "created_at", "content", "profile_picture_url", "sender__id", "edited", "file", "file_size", "is_pinned", ) ) async for message in … -

How to make my django views.py read excel sheet and display a blank cell, not "nan"
I am working on a project using django and plotly. It reads from an excel sheet and displays the data accordingly. Everything works except I have a child survey column that is only populated with some parent surveys. Because of that, the cells without a child survey are displaying 'nan' instead of just being empty. this is my function in views.py: def survey_status_view(request): # Fetch data for all CLINs and calculate necessary values clin_data = [] # Get all unique combinations of CLIN and child survey unique_clins = SurveyData.objects.values('clin', 'survey_child').distinct() for clin in unique_clins: clin_id = clin['clin'] child_survey = clin['survey_child'] # Check if the child_survey is 'None' (the string), and handle it appropriately if child_survey == 'None': child_survey = '' # Replace 'None' with an empty string # Filter by both clin and child_survey survey_data = SurveyData.objects.filter(clin=clin_id, survey_child=child_survey) # Total units for the current CLIN and child survey total_units = survey_data.first().units if survey_data.exists() else 0 # Count redeemed units based on non-null redemption dates redeemed_count = survey_data.filter(redemption_date__isnull=False).count() # Calculate funds for this CLIN and child survey total_funds = total_units * survey_data.first().denomination if total_units > 0 else 0 spent_funds = redeemed_count * survey_data.first().denomination if redeemed_count > 0 else 0 remaining_funds = … -

Why I can't install Django channels?
My OS is ubuntu 24.04. I am trying to create a chat application in Django. For that I need django channels and try to install them with pip install channels command. After executing this command I get this error: pip install channels error: externally-managed-environment × This environment is externally managed ╰─> To install Python packages system-wide, try apt install python3-xyz, where xyz is the package you are trying to install. If you wish to install a non-Debian-packaged Python package, create a virtual environment using python3 -m venv path/to/venv. Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make sure you have python3-full installed. If you wish to install a non-Debian packaged Python application, it may be easiest to use pipx install xyz, which will manage a virtual environment for you. Make sure you have pipx installed. See /usr/share/doc/python3.12/README.venv for more information. note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages. hint: See PEP 668 for the detailed specification.

Recommend a Tech Stack for a small CRM/Inventory web/mobile app with DB access and local logins
I have some Python experience with building machine learning models in Jupyter, but I am looking to build a web app with locally created logins but all these new tech stacks are a bit overwhelming. I want to learn full stack, but which route I need to choose now. As I understand Node.js has it's route and then you now also have FastHTML, Flask DJANGO etc, and then DB's to use. I need some guidance for a novice to start learning a tech stack. And then do you mostly stick with what you start with or is it a mix-match. Yes, I understand there is no perfect formula but this is why I am asking experts in the field with years experience and not GPT. Guidance pls !!PLEASE I DO NOT WANT AN ANSWER GENERATED BY ANY LLM, HAVE READ THEM ALREADY. GOOD OLD FASHIONED EXPERIENCE PLEASE!! -

Database Connections spiking randomly
I have an application with Django as backend. It is hosted on the EC2. The database is hosted on the AWS RDS Postgres SQL. The Connections to the database keep spiking to the maximum limit, even though we do not have that much users. The application is used by merely 10 people in the organization but the connections spike up to 80. Can anyone suggest what can be the issue behind this? I think it might be causing due to multiple requests from a single client leading to multiple connections. It will be great if somebody can help me out t find the cause. I tried redeploying the server as well as rebooting the rds instance but there is no change. I even tried adding the idle connection termination parameter through the rds parameter groups. When I checked the db for connection details, I saw multiple connections from same user ids. Can this be related to the issue? -

Making instances of Django records with a through model
Let's say you have a concept of a Battle, and in that battle there are Players and Enemies. The players are a simple ManyToMany, but Enemies require a Through model, because if there's a DB entry for "Goblin", players need to fight an INSTANCE of the Goblin model. Players may fight many Goblins, and each needs their own health/status at any given moment. So far, I've got a Django model like so (I'm simplifying the code for readability, and to focus on the main issue) class Battle(models.Model): players = ManyToMany(Player) enemies = ManyToMany(Enemy, through=EnemyThroughModel) With the appropriate adjustments to admin.py and such, this works in that I can attach multiple Enemies to a Battle and see them listed separately in admin, HOWEVER, those are all keyed to the same basic Enemy, and if I change one of them (say, they take damage), ALL the keyed references to that enemy now have their health reduced. Is there a neat way I can use through models to create a new instance of the enemies, so that they have independent health/mana/etc? -
VSCode not discovering pytests for Django Project
I am new to Pytest & Django, so all feedback and improvements are welcome. I am trying to use VSCode's testing sidebar with my Django Project, but it is unable to find the pytest files. Here are the commands I've run to create this example project: django-admin startproject LearningPytest pip install django-pytest Then I've created two files: pytest.ini and basic_tests.py, so my folder structure is as follows. DjangoPyTesting/ └───LearningPytest/ ├───LearningPytest/ │ ├───__init__.py │ ├───asgi.py │ ├───basic_tests.py │ ├───settings.py │ ├───urls.py │ ├───wsgi.py ├───manage.py └───pytest.ini pytest.ini [pytest] DJANGO_SETTINGS_MODULE = LearningPytest.settings python_files = tests.py test_*.py *_tests.py python_classes = Test* python_functions = test_* basic_tests.py class TestBasicMath: def setup_method(self, method): self.x = 2 self.y = 3 def test_addition(self): assert self.x + self.y == 5 def test_subtraction(self): assert self.y - self.x == 1 def test_multiplication(self): assert self.x * self.y == 6 Here is the problem, I want to use VSCode's sidebar to run my tests, but it cannot find them. This confuses me, because within my project if I run the following command: DjangoPytesting\LearningPytest>pytest it works successfully platform win32 -- Python 3.11.5, pytest-7.4.4, pluggy-1.3.0 rootdir: C:\Users\{me}\Desktop\DjangoPytesting\LearningPytest configfile: pytest.ini plugins: anyio-4.3.0, django-4.9.0 collected 3 items LearningPytest\basic_tests.py ...platform win32 -- Python 3.11.5, pytest-7.4.4, pluggy-1.3.0 rootdir: C:\Users\{me}\Desktop\DjangoPytesting\LearningPytest configfile: … -
Django backend user registration
I'm currently writing a system with users creation process involved. The system will have a 'site-administrator' who can create (and modify, delete) users. However, I'm stuck with the part of creating users. What I want is: Site Administrator creates a user Django will create a one time password and send this to the user (based on email) User logs in System detects it's the first time and forces the user (via frontend) to update password User updates password and logs in with new credentials Bearer tokens (access / refresh) are issued The frontend is VUE (with axios, pinia etc) but that's of no use for this question. The backend is Django, Djano Rest Framework, SimpleJWT and a MariaDB for storing info on the backend. Thank you for taking the time to answer this question. -
django stops running when i send an request to api
In the rest api I have a view that sends an otp sms to the user's phone . when I send a request to my api , It just sends another request to other server and waits for the response But It takes a while and django just stops working . I am worry about it . what if upload it to server and django can't handle multi requests and crashes in the real server with different request from multiple users? How can I fix this problem ? Also mu CPU has only 2 cores and I don't think using multi threading is an good idea! -
Automatically starting task queue for django-background-tasks
I'm building an application which involves a task queue from django-background-tasks. The issue that I'm facing is that I can't seem to start the queue automatically and have to manually run process_tasks in my application container. I've already tried running the process_tasks command within my Dockerfile, however this seems to not do anything as open tasks are not resolved. CMD ["bash", "-c", "python manage.py runserver 0.0.0.0:8000 && python manage.py process_tasks"] Has anyone experienced this issue, and if so how did you handle it? I tried to run the process_tasks command in my Dockerfile after executing runserver , I expected this to automatically start the task queue, however this did not yield any result.
