Django, gunicorn workers, scaling on Kubernetes
Kind of related to this post, we're in a similar position where we have a django application using gunicorn WSGI running on a Kubernetes cluster. I have read the official docs on how to configure num of workers (see design), but I still don't understand how this converts to a kubernetes pod running on a cluster utilising shared CPU? I have done various load tests on our test environment and the following is an idea of metrics I get and the resources in use: Django deployment containing 3 pods minimum but can scale to 20 Each pod has 1 CPU in Kubernetes config Each pod runs 3 gunicorn WSGI workers currently Pods run across Kubernetes nodes, each node has 4 CPUs Simple load testing suggests, we reach about 20-25rps maximum and then workers begin to restart, which seems quite bad! Scaling kicks in but its a lot slower than I'd like, despite optimisations, although we are slowed down a little by the istio-proxy side containers which have to start first before the app container Does anyone have any similar issues when it comes to scaling django apps? I know there can be a lot of differences depending on code, API … -
Image Upload Django with Ckeditor Failed Undefined
I'm trying to create a blog page with Django. I'm using CKEditor to add text. When I upload images locally, I don't have any issues, but I encounter a problem when I deploy the project to the server.

Django anon cart system not working on first visit to site
I wanted to implement an anonymous cart system to my django site. I saw on internet that I can achieve with the following javascript code: function getCookie(name) { let cookieValue = null; if (document.cookie && document.cookie !== '') { const cookies = document.cookie.split(';'); for (let i = 0; i < cookies.length; i++) { const cookie = cookies[i].trim(); // Does this cookie string begin with the name we want? if (cookie.substring(0, name.length + 1) === (name + '=')) { cookieValue = decodeURIComponent(cookie.substring(name.length + 1)); break; } } } return cookieValue; } const csrftoken = getCookie('csrftoken'); function uuidv4() { return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) { var r = Math.random() * 16 | 0, v = c == 'x' ? r : (r & 0x3 | 0x8); return v.toString(16); }); } let device = getCookie('device') if (device == null || device == undefined){ device = uuidv4() } document.cookie ='device=' + device + ";domain=;path=/" Which is embedded at the end of 'base.html' which is a template every other html uses. like this: <script src="{% static 'js/cookies.js'%}"></script> Followed by this home page code: class HomeView(ListView): template_name = "index.html" def get(self, *args, **kwargs): context = get_base_lists(self.request) ... return render(self.request, self.template_name, context) ... def get_base_lists(request): ... cart, created = … -

correct response code for role management
I’ve a user model and have some roles through other models (admin , doctor , patient, manager models ... etc) . I’ve one login endpoint for all . the patient, doctor only login with mobile number (didn’t handle it yet “means if he has email can login too”). patient only uses mobile application ... doctors on the web. all endpoints of each role are guarded with it’s related model , Like all users can login successfully as long as they’ve a User model , But when they try to access the admin , doctor… etc, they must have a related relation of the role … like if a user need to access the doctor endpoints , he must have a doctor instance . A user can have many roles (can register as many roles). What’s the best response code for this case if a user tried to access doctor endpoints without having a doctor instance ? 404 (user not found ) or 403 (unauthorized) and why please give a detailed response . Thanks I've implemented the response as a 403 , but "considering the doctor can be a patient" when he (doctor) logins through mobile (as patient) while he doesn't … -

Django ORM for custom python function

Why is caching not improving the performance in my django view?
I am trying to improve performance of a view by caching a given linear algebra expression and its corresponding result. I am using memcached and pymemcache but for some reason theres no performance gain. Heres my view: @api_view(['POST']) @login_required(login_url='/api/login/') @csrf_exempt def compute_lalg_expression(request): form = LinearAlgebraExpForm(request.POST) if form.is_valid(): new_expr = form.save(commit=False) data_expr = form.cleaned_data data_expr = data_expr['exp'] exp_hash = hashlib.md5(data_expr.encode()).hexdigest() alg_exp = cache.get(exp_hash) if not alg_exp: parsed_exp = parser.parse(data_expr) eval_data = evaluate(parsed_exp) expr_model = LinearAlgebraExpression(exp=eval_data) expr_model.save() create_action(request.user, 'computed an expression', expr_model) serializer = LinearAlgebraExpSerializer(expr_model) cache.set(exp_hash, serializer.data) return Response(serializer.data) return Response(alg_exp) And here is the client I am testing it with. I am testing it by removing the lines associated with caching above so I am removing exp_hash, alg_exp and so on so I remove the if statement that checks whether alg_exp is true or false and i remove cache_set. Anyways heres my client import aiohttp import asyncio import time async def make_request(session): url = 'http://127.0.0.1:8000/api/compute/' payload = {'exp': exp + '*' + exp2} # Replace with your POST data async with session.post(url, data=payload, auth=aiohttp.BasicAuth('jobpink', 'hello123')) as response: return await response.text() async def main(): # Adjust these values as needed num_requests = 5000 # Number of requests to send concurrency = 10 … -

Why is my Docx converter returning 'None'
I am new to web development and trying to create a language translation app in Django that translates uploaded documents. It relies on a series of interconversions between pdf and docx. When my code ouputs the translated document it cannot be opened. When I inspect the file type I saw it identified as XML and docx and it could be opened and read by MS Word when I changed the extension to docx(But it couldn't be read by any PDF readers). When I used my code python to analyze the file by printing the type and the contents of it I got NoneType and None. A working PDF of the file is found in mysite/mysite folder but the one output by my reConverter function that is sent to the browser is the problem file. I tried manually converting it using: wordObj = win32com.client.Dispatch('Word.Application') docObj = wordObj.Documents.Open(wordFilename) docObj.SaveAs(pdfFilename, FileFormat=wdFormatPDF) docObj.Close() wordObj.Quit() but got a CoInitialization error.

User Based Views

Any thoughts as to how to do this? I do have an example of existing code I can provide to show what I am trying to achieve; however it won't necessarily answer my question. Best, Neil -

Django-Docker: django.db.utils.OperationalError: could not translate host name "db" to address: Name or service not known
First-time docker-user: I recently added a cron job to my Django project and dockerized it. When I run docker-compose up --build, the system builds and runs the cron job, which exits with a code 137 (which is expected, since I'm running locally). When I try to run the cron job manually to troubleshoot methods of lowering the cron's CPU usage, I am met with: django.db.utils.OperationalError: could not translate host name "db" to address: Name or service not known This error is odd to me, since everything is fine upon build, but it seems like the command no longer knows what the database is outside of the build even with the project running.

Assign model permissions of Model1 to a Model2 in django using django guardians
I am using Django Guardians in my project and it works fine so far, but there is some problem: I need to assign permissions from model1 to the instance of the model2. Real example: The shop has some contracts and the shop owner wants to assign his employees permission to change contract fields (e.g. field1). So we have 3 models now: Shop, Contract, and User, and each model has it's own defined permissions per field like: can_change_field1, ... All permissions that employee can have must be related to the Shop model because when a shop owner assign contract permissions to his employee (to change field1 in contract in shop1), it mustn't affect another shop (So user will not be able to change that field e.g. field1 in shop2,...). 1st solution can be: to create all permissions in shop model (for all models: Contract,...). But it seems kinda of messy to me. What do you think? Please, Can you suggest some nice solution to this problem? -

However, the response parsed from the server is not same local vs prod in cloud environment. this.authService .login(this.f.username.value, this.f.password.value) .pipe(first()) .subscribe({ next: () => { // get return url from query parameters or default to home page this.alertService.success("Login successful"); const returnUrl = this.route.snapshot.queryParams['returnUrl'] || '/'; this.router.navigateByUrl(returnUrl); }, error: (error) => { this.alertService.error(error); this.loading = false; }, }); this works well locally the response shows { "headers": { "normalizedNames": {}, "lazyUpdate": null }, "status": 401, "statusText": "Unauthorized", "url": "http://localhost:4200/api/v1/token/", "ok": false, "name": "HttpErrorResponse", "message": "Http failure response for http://localhost:4200/api/v1/token/: 401 Unauthorized", "error": { "type": "client_error", "errors": [ { "code": "no_active_account", "detail": "No active account found with the given credentials", "attr": null } ] } however, in prod it is giving me different statusText somehow { "headers": { "normalizedNames": {}, "lazyUpdate": null }, "status": 401, "statusText": "OK", "url": "https://remoteurl-cloudrun-app/api/v1/token/", "ok": false, "name": "HttpErrorResponse", "message": "Http failure response for https://simpledc-tkbsnc6b4a-uc.a.run.app/api/v1/token/: 401 OK", "error": { "type": "client_error", "errors": [ { "code": "no_active_account", "detail": "No active account found with the given credentials", "attr": null } ] } I can't understand why. …
