FormData file upload to Django model?
I'm trying to upload a file through a jQuery ajax request, using FormData. When I set processData and contentType to false, I get the error Forbidden (CSRF token missing.). When I remove those, I get the error Uncaught TypeError: 'slice' called on an object that does not implement interface Blob.. What am I missing here? $(".form").on("submit", function(event) { event.preventDefault(); $.ajax({ url: "/upload_profile_pic/", type: "POST", data: { "profile_pic": formData.get("file"), "csrfmiddlewaretoken": $(this).find("input[name='csrfmiddlewaretoken']").val() }, }, success: function (data) { console.log("success: "+data); }, error: function (data) { console.log(data); } }); }); -
Django vs PHP 8.*: Memory usage with 1000 concurrent visitors
I'm currently deciding between Django (Python) and PHP 8.* for a very large project that expects high traffic. Memory usage is a crucial factor for me since the website will need to handle a significant number of concurrent visitors. For example, let's say the site needs to handle 1000 concurrent visitors. Please consider that the project will be well optimized. From what I understand: PHP creates a new process for each request, which might lead to higher memory consumption under heavy load since each request is handled separately. Django, on the other hand, uses a persistent process to handle requests, which might help with better memory management but could also cause its own memory-related concerns under high traffic. I've asked ChatGPT for advice on this, but it gives random and wrong answers, so I don't trust it. I'm looking for insights or benchmarks that compare the memory usage of PHP and Django when handling high traffic and concurrent users. Specifically, how much memory each might use when handling around 1000 concurrent visitors, and any research on how each stacks up in terms of scalability and memory efficiency. Which language/framework would you recommend if memory usage is a key factor for … -

Struggling with Vitess MySQL Integration: Issue
I’m working with Vitess on my server and trying to integrate it with a simple demo Django project using the Vitess MySQL databases. I’ve already set up Vitess using Docker and have successfully logged into MySQL within the Vitess container, and for the container, I used to create a subnet so the container has a separate IP.

Docker. How to fill volume at startup
I use docker-compose to run a Django project. My goal is for docker to start filled with existing data (statics, database, and all the contents of the media directory). Currently, statics are collected and distributed via volume. The database starts from a prepared dump. /media directory added to .dockerignore The question is, how to correctly fill the media volume from the media directory when you first run docker compose (that is, when the media volume is still empty)? docker-compose.yaml file: volumes: mysql_data: static: media: services: db: image: mysql:8.0 restart: always volumes: - mysql_data:/var/lib/mysql - ./database_dump.sql:/docker-entrypoint-initdb.d/dump.sql environment: - MYSQL_DATABASE=${MYSQL_DATABASE} - MYSQL_USER=${MYSQL_USER} - MYSQL_PASSWORD=${MYSQL_PASSWORD} - MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD} env_file: - .env backend: build: ./ depends_on: - db restart: always volumes: - static:/app/static/ - media:/app/media/ env_file: - .env nginx: build: ./gateway/ depends_on: - backend ports: - "8000:80" restart: always volumes: - static:/static/ - media:/media/ Dockerfile: FROM python:3.11 WORKDIR /app ENV PYTHONDONTWRITEBYTECODE=1 ENV PYTHONUNBUFFERED=1 ENV DJANGO_SETTINGS_MODULE='app.settings' RUN apt-get update && apt-get install -y netcat-openbsd COPY ./requirements.pip ./ RUN pip install --upgrade pip && pip install -r requirements.pip --no-cache-dir COPY . .

What's the correct way to use transaction.on_commit with Celery tasks in Django?
Approach 1: Without transaction.atomic Source: https://adamj.eu/tech/2022/08/22/use-partial-with-djangos-transaction-on-commit/ def order_created(order): order.status = 'created' order.save() transaction.on_commit( partial(send_order_email.delay, order_id=order.id) ) Approach 2: With transaction.atomic def order_created(order): with transaction.atomic(): order.status = 'created' order.save() transaction.on_commit( partial(send_order_email.delay, order_id=order.id) ) Which approach is correct and why? The save() operation makes database changes, but examples differ on whether transaction.atomic is needed. (ATOMIC_REQUESTS=False in settings) -

Django: How to Represent and Query Symmetrical Relationships for a Family Tree?
I am building a family tree application in Django where I need to represent and query marriages symmetrically. Each marriage should have only one record, and the relationship should include both partners without duplicating data. Here's the relevant model structure: class Person(models.Model): first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) spouses = models.ManyToManyField( 'self', through="Marriage", symmetrical=True, related_name="partners" ) class Marriage(models.Model): person1 = models.ForeignKey(Person, on_delete=models.CASCADE, related_name="marriages_as_person1") person2 = models.ForeignKey(Person, on_delete=models.CASCADE, related_name="marriages_as_person2") start_date = models.DateField(null=True, blank=True) end_date = models.DateField(null=True, blank=True) I want to: Ensure both partners appear as spouses for each other symmetrically. Avoid duplicate entries for the same marriage. Efficiently query all spouses of a person. Here’s the code I’m using to query spouses: # Query spouses for a person p1 = Person.objects.create() p2 = Person.objects.create() Marriage.objects.create(person1=p1, person2=p2) p1.spouses.all() # Returns list containing p2 p2.spouses.all() # Returns empty list However, I’m facing challenges: If p1 spouses are queried, it should contain p2 and if p2 spouses are queried, it should contain p1 Both queries are not symmetrical Questions: Is my model structure correct for representing marriages symmetrically? If not, what improvements should I make? How can I efficiently query all spouses of a person in a database-optimized way while ensuring symmetry? -

BadRequest can't return JSON?
I am trying to return a JSON object along with a 400 error code. This correctly returns the object (e.g. {"email": ["A user with that email address already exists."]}: return HttpResponse(json.dumps(dict(form.errors.items()))) Whereas these all just returns an unreadable (by javascript) object ([object Object]): return BadRequest(json.dumps(dict(form.errors.items()))) return HttpResponseBadRequest(json.dumps(dict(form.errors.items()))) return BadRequest(json.dumps(dict(form.errors.items())), content_type='application/json') I've tried several other methods of sending an error code but the results were the same.

How to configure dynamic language switching for API responses using i18n_patterns in Django?
I am working on a Django project and need to implement multilingual support for my REST API. I want the API to return responses in the selected language based on the URL prefix (e.g., /en/, /ml/) using i18n_patterns. I’ve done the following: In settings.py, I’ve defined the available languages: LANGUAGES = [ ('en', 'English'), ('ml', 'Malayalam'), ] LANGUAGE_CODE = 'en' I’ve added 'django.middleware.locale.LocaleMiddleware' to the MIDDLEWARE setting: MIDDLEWARE = [ ... # other middlewares 'django.middleware.locale.LocaleMiddleware', ] In the project’s urls.py, I’ve used i18n_patterns to ensure the URLs are prefixed with the language code: from django.conf.urls.i18n import i18n_patterns urlpatterns = [ path('admin/', admin.site.urls), path('auth/', include('accounts.urls')), path('app/', include('app.urls')) ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) urlpatterns = i18n_patterns(*urlpatterns) The Issue: While I can specify the language via the URL (e.g., /ml/ for Malayalam), the API responses are not being automatically translated to the selected language. The responses remain in English even when the Accept-Language header or language prefix is set to another language (e.g., Malayalam) What I Expect: I expect the API responses to be auto-translated into the selected language (e.g., Malayalam) based on the URL prefix or Accept-Language header. What I Have Tried: I’ve confirmed that LocaleMiddleware is active in MIDDLEWARE. I’ve ensured that … -

Custom generic istruthy/isfalsy lookup doesn't work on Foreign Keys
In my Django project, I'm in need of a generic istruthy/isfalsy lookup that would work on any type of database field.

Temporarily load a fixture for development
I would like to create a lot of dummy products for use in development. The dummy products need to be in the development database, in addition to a copy of all of the data that the production database has, so that I can see what the dummy products will look like in the website. How can I do this easily? I've looked into fixtures, but I can't figure out how to "apply" a fixture on top of a copy of the production database, and how I might be able to unapply it when I'm done with that part of development. -
Is this djoser implementation secure?
This question may be too broad for StackOverflow, but I'm not sure where else to go for help. I wrote a simple authentication system in Django with Djoser and its JWT implementation, using jQuery on the frontend. I really don't know what I'm doing though, and I'm about 99% sure I did it wrong and it's totally insecure. First, when a user submits the login form, I send a POST request to retrieve a refresh token and an access token. The refresh token is stored as a cookie, and the access token is stored in sessionStorage: // Post the form $.post("/auth/jwt/create/", $(this).serialize()) // Success: store tokens & redirect .done(function(data) { // Logged in: set redirect path & store tokens if (data.refresh !== "undefined" && data.access !== "undefined") { Cookies.set("refresh_token", data.refresh, { expires: 30, secure: true, sameSite: "strict" }); sessionStorage.setItem("access_token", data.access); } }) I have another simple script that runs every time a page is loaded. There, I verify the access token, attempt a refresh if it's invalid, fetch user data using the access token, then post that user data to the backend to login. This script also logs the user out if on the logout page: // Log in or … -
Data not saved to database
I don't know what's going on here, whenever I try to create a buzz with the status set to Draft (this is also the default status set on the model) Django returns a 302 response and does not saved it to the database.

Django Allauth's Google Login Redirect and Page Design
