how to use static in django project
Is this not the correct way of making use of Django's static directories in code?

Run Celery tasks on Railway
I deployed a Django project in Railway, and it uses Celery and Redis to perform an scheduled task. The project is successfully online, but the Celery tasks are not performed. If I execute the Celery worker from my computer's terminal using the Railway CLI, the tasks are performed as expected, and the results are saved in the Railway's PostgreSQL, and thus those results are displayed in the on-line site. Also, the redis server used is also the one from Railway. However, Celery is operating in 'local'. This is the log on my local terminal showing the Celery is running local, and the Redis server is the one up in Railway: -------------- celery@MacBook-Pro-de-Corey.local v5.2.7 (dawn-chorus) --- ***** ----- -- ******* ---- macOS-13.1-arm64-arm-64bit 2023-01-11 23:08:34 - *** --- * --- - ** ---------- [config] - ** ---------- .> app: suii:0x1027e86a0 - ** ---------- .> transport: redis://default:**@containers-us-west-28.railway.app:7078// - ** ---------- .> results: - *** --- * --- .> concurrency: 10 (prefork) -- ******* ---- .> task events: OFF (enable -E to monitor tasks in this worker) --- ***** ----- -------------- [queues] .> celery exchange=celery(direct) key=celery [tasks] . kansoku.tasks.suii_kakunin I included this line of code in the Procfile regarding to the worker (as I … -

vscode testing with pytest for dockerized Django project
i want to debug my tests in vscode for my Django project witch is set up in a docker container but the problem is it always says pytest discovery error, sometimes it seems to not be able to import modules(for example models) inside the test file and after some configuration it seems to not find the test file itself. all the folders of my project have an init.py file so everything is treated as a package, by the way there is no problem importing modules in my Django project. the odd thing is when I run pytest inside of my docker container it works fine but I want to debug the tests. i am fairly new to this so any help would be welcomeenter image description here I enabled pytest in the .vscode/settings.jsonenter image description here file as some other settings I tried also creating a .env file with PYTHONPATH in it to my root folder cause every tutorial I found work with a virtual environment and not a docker container -
Errors in importing a react library created using rollup
I am writing a React/Next app. I have created a react accordion-component external to the app. I am using rollup to create a package and importing that package into my app. When I run the app I get the error ./node_modules/@zeilsell-user1/accordion-component/dist/esm/index.js Module parse failed: Unexpected token (1:4) You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders use clientfunction getDefaultExportFromCjs (x) { | return x && x.__esModule && Object.prototype.hasOwnProperty.call(x, 'default') ? x['default'] : x; | } I do not understand why I am seeing this error. The component is ESM so why the CSJ function? Nexrjs uses webpack, but that should handle csj, I can't find anything about loaders anyway. I am assuming that the issue is on the component side, so I have included the rollup, tsconfig and package files below. Really appreciate any help that the community can offer me as I have been stuck on this problem for ages. my rollup.config.mjs import {nodeResolve} from '@rollup/plugin-node-resolve'; import commonjs from "@rollup/plugin-commonjs"; import typescript from "rollup-plugin-typescript2"; import banner2 from "rollup-plugin-banner2"; import dts from "rollup-plugin-dts"; import packageJson from "./package.json" assert { type: "json" }; export default [ { input: … -

"detail": "CSRF Failed: CSRF token missing."
I was trying to test my API in DJango, but while trying to use a POST request to create a user, the following error shows up: "detail": "CSRF Failed: CSRF token missing." What should I do? Can I remove this? Or how should I pass the CSRF also in testing and in production? In theory, I put the false in CSRF_COOKIE_SECURE, so, I don't know what to do. -

Why DRF uses PUT to send files?
I'm trying to understand how file management works in Django Rest Framework, and a question lingers in my mind: Why does Django use PUT to update files? Is it possible to do the same with the PATCH method? How would I be able to push binaries through the patch? Example of model: class User(AbstractUser): id = HashidAutoField(prefix='user_', primary_key=True) picture = models.ImageField(blank=True, null=True, verbose_name=_("profile picture"), storage=PublicMediaStorage(), upload_to=upload_to) When I try to send using the patch method it only allows me to send in json format, I don't know if there is any way to user PATCH and form-data. For Patch I have something like this: { "user": { "username": "", "first_name": "", "password": "", "password_confirm": "", "email": "", "picture": null } } -
Complex Django query involving an ArrayField & coefficients
On the one hand, let us consider this Django model: from django.db import models from uuid import UUID class Entry(models.Model): id = models.UUIDField(primary_key=True, default=uuid4, editable=False) value = models.DecimalField(decimal_places=12, max_digits=22) items = ArrayField(base_field=models.UUIDField(null=False, blank=False), default=list) On the other hand, let us say we have a dictionary coefficients looking like: coefficients = {item1_uuid: item1_coef, item2_uuid: item2_coef, ... } Entry.value is intended to be distributed among the Entry.items according to coefficients (with sum(coefficients.values()) = Decimal(1)). Using Django ORM, what would be the most efficient way (in a single SQL query) to get the sum of the values of my Entries for a single Item given those coefficients? For instance, in that specific case, for item1 I want to get 168.5454...: 100 * 1 + 150 * (0.2 / (0.2 + 0.35)) + 70 * 0.2. | Entry ID | Value | Items | |-------|-------|--------------------------------------| | uuid1 | 100 | [item1_uuid] | | uuid2 | 150 | [item1_uuid, item2_uuid] | | uuid3 | 70 | [item1_uuid, item2_uuid, item3_uuid] | coefficients = { item1_uuid: Decimal("0.2"), item2_uuid: Decimal("0.35"), item3_uuid: Decimal("0.45") } So far this is what I was thinking about, unsuccessfully: def get_value_for_item(coefficients: dict[UUID, Decimal], item: Item) -> Decimal: queryset = Entry.objects.filter(items__contains=item.pk) # I'm missing a … -
How to add a new "comment" or "flag" field to every model field of existing model?
Disclaimer: I can wipe out the database anytime. So while answering this, please don't care about migrations and stuff. Imagine me having a model with multiple values: class Compound(models.Model): color = models.CharField(max_length=20, blank=True, default="") brand = models.CharField(max_length=200, blank=True, default="") temperature = models.FloatField(null=True, blank=True) melting_temp = models.FloatField(null=True, blank=True) # more (~20) especially numeric values as model fields Now I want to add a comment to be stored for every value of that model. For example I want to add a comment "measured in winter" to the temperature model field. What is the best approach to do that? My brainstorming came up with: By hand add 20 more model fields like temperature_comment = ... but that sounds not very DRY Add one big json field which stores every comment. But how do I create a Form with such a json field? Because I want to separate each input field for related value. I would probably have to use javascript which I would want to avoid. Add a model for every value and connect them to Compound via OneToOneFields. But how do I then create a Form for Compound? Because I want to create a Compound utilizing one form. I do not want … -

Using OpenCV HandDetector with a webcam in Django
I am working on a Django project that involves using a webcam to play a rock-paper-scissors game against a computer. I have implemented the OpenCV HandDetector algorithm to detect a hand in the webcam video feed, and a Keras classifier to classify the hand gesture. However, I am running into an issue with getting the HandDetector to work properly with the webcam video. I have tried using a single still image from the webcam, but the HandDetector does not work well with just one image. I think the solution is to use a video of the hand, but I am not sure how to implement this in my Django project. Here is the code for my jQuery script that captures the video from the webcam and sends it to a Django view: <div class="container"> <div class="row"> <div class="col-md-6"> <video id="webcam" width="640" height="480" autoplay></video> </div> <div class="col-md-6"> <button id="play-button" class="btn btn-primary" onclick="play()">Play</button> </div> </div> </div> <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script> <script> $(document).ready(function() { startWebcam(); }); var video = document.getElementById('webcam'); var stream; function startWebcam() { navigator.mediaDevices.getUserMedia({ video: true, audio: false }) .then(function(localMediaStream) { stream = localMediaStream; video.srcObject = localMediaStream; video.play(); }) .catch(function(err) { console.log("An error occurred: " + err); }); } function play() { // … -

But my request.post is not working. <form method="POST"> {% csrf_token %} <ul> <li> <div class="form-group quantity-box"> <label class="control-label">Quantity</label> <input class="form-control" id="quantity" value="0" min="0" max="20" type="number" /> </div> </li> </ul> <div class="price-box-bar"> <div class="cart-and-bay-btn"> <a class="btn hvr-hover" data-fancybox-close="" href="#" >Buy New</a> <button type = "submit"> <a class="btn hvr-hover" data-fancybox-close="" id= "qtyButton" data-fancybox-close="" href="{% url 'addCart' %}">Add to cart</a> </button> </form> my js script $('#qtyButton').click(function(e){ e.preventDefault(); var qty = $('#quantity').val(); var id = {{product.id}}; $.ajax({ type: "POST", url: "{% url 'addCart' %}", dataType: 'json', data: { "quantity":qty, "product_id":{{product.id}}, } }); }); my wiew.py file def addCart(request): url = request.META.get('HTTP_REFERER') if request.method == 'POST': post = request.POST quantity = post.get('quantity') id = post.get('product_id') item = Product.objects.get(id=id) Cart.objects.get_or_create(user_id=request.user, product_id=item, quantity=quantity) else: return render(request, 'cart.html') return redirect(request.META.get("HTTP_REFERER", "/")) I tried so many things. But none of them is working. What should i do ?
