Django + Celery + PySpark inside Docker raises SystemExit: 1 and NoSuchFileException when creating SparkSession
I'm running a Django application that uses Celery tasks and PySpark inside a Docker container. One of my Celery tasks calls a function that initializes a SparkSession using getOrCreate().

Django overwriting save_related & copying from linked sql tables
In django python, I am able to overwrite the save_related function (when save_as = True) so the instance I am trying to copy is saved and copied properly. When I save, though, I want other objects in other tables linked by an ID in the sql database that should be copied when the. For example we have table A, and I can copy instances in A, but I need B, a related sql table to A, to duplicate in B's table where a's id is equal to b's id. -
writable nested model serializer requires manual parsing of request.data
After a lot of trouble I finally got a Django writable nested model serializer working using drf-writable-nested, for nested data with a reverse foreign key relationship. Currently this requires me to copy and manually parse request.data for all fields to create a new object before sending it to my serializer. If I don't do this I get the following (prints of serializer.data and errors respectively): serializer.data { "leerling": "2", "omschrijving": "Basispakket", "betaaltermijn": "14 dagen", "is_credit": false, "tegoeden": [ { "[aantal]": "1", "[prijs]": "450", "[btw_tarief]": "9%" }, { "[aantal]": "1", "[prijs]": "45", "[btw_tarief]": "21%" } ] } serializer.errors { "tegoeden": [ { "btw_tarief": [ "This field is required." ] }, { "btw_tarief": [ "This field is required." ] } ] } Some fields don't error because they are not required/have a default value. I tried manually declaring the JSON without brackets as input for the serializer, and then it works. So the problem is caused by the brackets. Its working now, manually parsing the request.data Querydict, but it feels hacky and probably not how it's supposed to be done. I'm probably missing something. -

Django/Apache/mod_wsgi Deployment Issue: Internal Server Error & Redirect Loop on cPanel (AlmaLinux 9)
I'm an intern trying to deploy a Django application on a cPanel server, and I've run into a persistent "Internal Server Error" coupled with an Apache redirect loop. I've been troubleshooting for over two days with various AI helpers, but I can't pinpoint the exact cause. Any fresh perspectives ?? My Setup: Server OS : AlmaLinux 9.6 (Sage Margay) Hosting Environment: cPanel (My cPanel account does not have the "Setup Python App" option, which is why I'm using a manual Apache/mod_wsgi configuration.) Django Deployment: Apache + mod_wsgi No .htaccess content at all.

How to reduce latency in translating the speech to text (real time) in a Django-React project?
I have implemented a speech to text translation in my django-react project. I am capturing the audio using the Web Audio API, ie, using navigator.mediaDevices.getUserMedia to access the microphone, AudioContext to create a processing pipeline, MediaStreamAudioSourceNode to input the audio stream, AudioWorkletNode to process chunks into Float32Array data, and AnalyserNode for VAD-based segmentation.processes it into 16-bit PCM-compatible segments, and streams it to the Django backend via web socket. The backend, implemented in consumers.py as an AudioConsumer (an AsyncWebsocketConsumer), receives audio segments or batches from the frontend via WebSocket, intelligently queues them using a ServerSideQueueManager for immediate or batched processing based on duration and energy, and processes them using the Gemini API (Gemini-2.0-flash-001) for transcription and translation into English. Audio data is converted to WAV format, sent to the Gemini API for processing, and the resulting transcription/translation is broadcast to connected clients in the Zoom meeting room group. The system optimizes performance with configurable batching (e.g., max batch size of 3, 3-second wait time) and handles errors with retries and logging. Now there is a latency in displaying the translated text in the frontend. There is an intial delay of 10s inorder to display the first translated text. Subsequent text will … -
How to change the breakpoint at which changelist table becomes stacked?
In Unfold admin, the changelist table switches to a stacked layout on small screens — likely due to Tailwind classes like block and lg:table. I’d like to change the breakpoint at which this layout switch happens (for example, use md instead of lg, or disable it entirely to keep horizontal scrolling). How can this behavior be customized or overridden cleanly? -
How to find and join active Django communities for learning and collaboration?
How can I actively engage with the Django community? Looking for forums, Discord/Slack groups, or events to discuss best practices, ask questions, and contribute. Any recommendations?

Django SSL error during send_mail() while explicitly using TLS
I'm trying to perform a send_mail() call in my Django application, but the mails are not sending.

Django manage.py Command KeyboardInterrupt cleanup code execution

Working in django with data with a saved history of changes
I am creating an information system in which some entities have separate attributes or a set of them, for which it is necessary to store a history of changes with reference to the date of their relevance for further processing in conjunction with other entities. In particular, I have main entity Customer and one or a related set of date-related attributes (for example, the official names of Customer), which may change over time. What is the best or possible way to implement the interaction of the model for main entity, but with their history must be preserved? Here’s what I’ve come up with so far. The class code is probably redundant, but this is done specifically to demonstrate the problem. Main class: class Customer(models.Model): name = models.CharField(max_length=128, verbose_name='Customer system name') # A key for relation with current value of secondary class # I have doubts about the correctness of adding this field, # but so far I have not come up with anything better. legal_names = models.ForeignKey('CustomerNames', on_delete=models.SET_NULL, null=True, blank=True, verbose_name='Legal customer names') Auxiliary (secondary) class: class CustomerNames(models.Model): # A key for relation with the main model, specifying a list of names customer = models.ForeignKey(Customer, on_delete=models.CASCADE, related_name='customer_names', verbose_name='Customer') short_name = … -
Why postgres service if If you buy a managed PostgreSQL database from DigitalOcean?
Why do we need to add postgres service if we buy postgress database on DigitalOcean ? For me there is two ways to setup our database : Solution 1 : Let docker handle it by taking advantage of docker network. We configure Docker then to run PostgreSQL as a service. For this solution, no need to buy DigitalOcean database since we can map with volumes (./data/db:/var/lib/postgresql/data). Data persisted with volumes then Solution 2 : Buy DigitalOcean database. For this solution no need to setup postgress service with docker. PostgreSQL runs on DigitalOcean's infrastructure. We take advantages of DigitalOcean. DigitalOcean handles maintenance, backups, security, ... in this case. So for me, No PostgreSQL Docker service needed. So I am in this django project and despite the fact that we have our PostgreSQL runs on DigitalOcean's infrastructure in the docker-compose we steel have postgres service. So my question is why then do we need postgress service if we decide to take DigitalOcean database offer ? why do we need postgress service in this case for docker ? Just wanna understand. My crew gave me some explanations but do not understand very well. So can anyone help me to understood ? -
How to handle unfamiliar real-time tasks in Django projects without proper documentation?
We’re working with backend developers who frequently encounter real-time tasks that fall outside their core experience—for example, integrating Django applications with older third-party systems (e.g., SOAP-based services, custom XML APIs) or poorly documented internal tools. A common issue involves connecting to a SOAP API using zeep, and getting stuck handling WSSE or custom header authentication. The developers often find minimal guidance in the official docs, and very few examples online. In situations like this, where tasks are time-sensitive and documentation is lacking, what’s an effective way to: Break down the problem Debug effectively Find reliable patterns or tools to apply We’re looking to understand how experienced Django or backend developers approach unknowns like this under time pressure. I used the zeep library in Django to connect with a SOAP API. I followed the official docs and tried loading the WSDL and passing headers via the client. I expected a successful response from the server, but instead, I’m getting authentication or connection errors. I’ve tried different header formats and debug logs but can’t figure out what’s wrong. Looking for better ways to handle such situations. -

How can I organize the structure of entering the city/restaurant tables of the Django database?
Good day! I have a plan for the database structure. An example is in the figure below. For example, I have - all coffee shops - within one region - state or several regions. In one city there are several cafes. In total, there can be 200 cafes and 10 cities. The problem is how to enter data on cafes in the database tables. And also change them if necessary. Enter data through forms. Each cafe also has the following parameters - address, Internet page, profitability, income, number of staff, i.e. data belonging to one cafe. As well as staff and menu. I think to first enter the cities in which there will be cafes. And then enter the names of the cafes. And even later other parameters through other forms. How can I make it so that at the second stage only the name, address is entered and then successively filled with other data?

Update LANGUAGE_CODE in Wagtail before internationalization?
I've developed a site in Wagtail, but missed to update the LANGUAGE_CODE before the first (and several other) migrations. In the Internationalization instructions the following is noted: "If you have changed the LANGUAGE_CODE setting since updating to Wagtail 2.11, you will need to manually update the record in the Locale model too before enabling internationalization, as your existing content will be assigned to the old code." But, how do I manually update the the record in the Locale model? -

Problems integrating Django and Tableau with Web Data Connector (WDC)
I’m working on a project where I need to integrate data from my Django application into Tableau using a Web Data Connector (WDC). However, I’m running into several issues and would appreciate any help or guidance from the community. Setup: Backend: Django (Python) Goal: Tableau Dashboard Connection: Web Data Connector (WDC) What I’ve done so far: I created a WDC that fetches data from my Django API. The API provides JSON data, which I want to pass to Tableau via the WDC. The WDC was built using JavaScript and connects to the Django API. Issues: CORS Errors: Tableau seems to have issues with the Cross-Origin Resource Sharing (CORS) settings in my Django application. I’ve installed and configured django-cors-headers, but the error persists. Slow Data Transfer: When dealing with large datasets, the transfer from Django to Tableau is extremely slow. Authentication: My Django API uses token-based authentication, but I’m unsure how to implement this securely in the WDC. My Questions: How can I resolve CORS issues between Django and Tableau? Are there best practices to speed up data transfer between Django and Tableau? How can I securely implement authentication (e.g., token-based or OAuth) in the WDC for Django?

How can I send data via copy paste operation in Django Views or model?
I have such a very difficult problem. Which is very specific and not easy to enter data. I am thinking how to send data to the database or, as an option, just send data to the code in the internal Django code for processing in Views. Is it possible, for example, to have the ability to send data not one by one in the singular, to fill in the input field. Fill in the input field not only one in the singular. For example, as the most common case of data processing in office or other applications - the copy / paste operation. So in this frequent popular operation - for example, we want to copy several elements in an Excel table and try to insert them somehow send to the code in the internal Django code for processing in Views. Is it possible to implement something similar? So as not to manually enter data, but somehow have the ability to do this in a semi-automatic form - by copying several cells with data and pasting them into some kind of form or something similar?
