Django nested serializer instance update issue
I am building a django backend rest API and I have an issue which I can't overcome. So I have two models. #1 Company Model: class Company(models.Model): companyID = models.BigAutoField(primary_key=True) name = models.CharField(max_length=50) email = models.CharField(max_length=50) description = models.CharField(max_length=500,blank=True, null=True) #2 Employee Model: class Employee(models.Model): JOB_CHOICES = [ ('software engineer', 'Software Engineer'), ('data scientist', 'Data Scientist'), ('product manager', 'Product Manager'), ('data analyst', 'Data Analyst'), ('software developer', 'Software Developer'), ('ui/ux designer', 'Ui/UX Designer'), ('manager', 'Manager'), ('software tester', 'Software Tester'), ('accountant', 'Accountant') ] employeeID = models.BigAutoField(primary_key=True) companyID = models.ForeignKey(Company, db_column="companyID", related_name='employees', on_delete=models.CASCADE) name = models.CharField(max_length=50) email = models.CharField(max_length=50) age = models.IntegerField(default=18, validators=[MinValueValidator(18), MaxValueValidator(100)]) job = models.CharField(max_length=50, choices=JOB_CHOICES, default='software engineer') cv = models.CharField(max_length=500, null=True, blank=True) I would like to create a serializer which is get one object like this (from PUT request): { "companyID": 3, "name": "New Name", "email": "test@gmail.com", "description": "test", "employees": [ { "employeeID": 31, "name": "Test USER", "email": "goreca7783@fulwark.com", "age": 18, "job": "data analyst" } ] } and it should update all of the values in the database.

Passing parameters to a database backend in Django
I have created a Django backend to manage databases. I need to be able to pass values to it based on the user. I have created this Middleware for that purpose, and it behaves correctly in the development environment, PyCharm. The question is, will it work correctly in production if it's running with multiple threads since I'm using Gunicorn? My code, I use the session variable SESSION_B2J for this, and from the backend, I call get_session_b2j to retrieve values: import threading def get_session_b2j(): thread_local = B2jBakendMiddleware.thread_local if hasattr(thread_local, 'session_b2j'): return thread_local.session_b2j def set_session_b2j(session_b2j): thread_local = B2jBakendMiddleware.thread_local thread_local.session_b2j = session_b2j class B2jBakendMiddleware(object): thread_local = threading.local() def __init__(self, get_response): self.get_response = get_response def __call__(self, request): self.thread_local.session_b2j = request.session.get('SESSION_B2J') response = self.get_response(request) return response -

Where to put bussiness logic in Django (DRF)?
Despite it is very popular question and already has a lot of answers, I don't really get it. I understand that putting tons of logic in views is not a good idea, so in my projects I create files like utils, logic, helpers. But the problem is that I don't know where should I call those "logical" functions? Should I make them as a property or method of model instance, or should I call it in a view passing model instance as an argument? For example in my current pet-project I have Question and Answer models. Question has is_solved Boolean (default=False) field which means if the question is solved or not, and Answer has is_solving Boolean field (default=False) as well and if True, it means that the answer helped to solve an issue. I have a function in logic file which handles it. Here is the code: def vote_answer_solving(answer: Answer, related_question: Question): if answer.is_solving: answer.is_solving = False related_question.is_solved = False else: if related_question.question_answers.filter(is_solving=True).exists(): is_solving_answer = related_question.question_answers.get(is_solving=True) is_solving_answer.is_solving = False is_solving_answer.save() answer.is_solving = True related_question.is_solved = True related_question.save() answer.save() I call it in a view, where user requests the endpoint and the logic is handled by the function.

Python library for 3D human pose animation
I have some 3D human pose data with x, y and z coordinates estimated from a video. I want to be able to animate this data and display it on a web browser to produce something similar to the following: Currently I am using Matplotlib to animate the data and it works quite well however displaying it on a browser takes a long time (around 10 seconds) for a very short video clip and I am not sure how to place the image data/video onto the animation like the example above. Is there a better library I can use to animate this data and display it on a web browser in a reasonable amount of time. Here is the code for the 3D animation using Matplotlib and a frame from the animation it produces: store = DataStore() store.populate_poses(sid, clip_num): frames = [] for p in store.get_poses(): fig = plt.figure() ax = fig.add_subplot(111, projection='3d') keypoints = [] for kp in p.get("keypoints3D"): x, y, z = kp['x'], kp['y'], kp['z'] # Swap Y and Z axes, and adjust X, Y, Z as needed x_new = x # X remains the same y_new = z # Y in Matplotlib is -Z in BlazePose z_new … -
Installing Python Frameworks on Respberry Pie
I use my laptop for things other than coding. My Python coding now consists only of what I can do on PieCharm, which is inside my VR Box. For projects, I need to install Flask and other frameworks. My laptop can barely handle the VR Box, so I don't want to subject it to a framework. Can I purchase a Raspberry Pie and install all my Python frameworks on that? What Python projects can't I do on Raspberry Pie? I haven't tried much because I haven't purchased a Raspberry Pie yet. Money is tight and I want to make sure I use it before I buy it. Things are also a little complicated because I've been living in Ukraine throughout the war -

JWT Authentication Error (401) When Fetching Django API Data from React App via Cookies
I have an API created in Django, which uses a JWT token to validate the user's authentication. Once I log in, I obtain a token that I use to call the 'hello' endpoint to fetch information. Everything works perfectly in this regard, but the problem arises when I integrate it into my React app. My React app allows me to log in and store the JWT token in cookies. In the 'Home.js' file, there's a button responsible for fetching data from the 'hello' endpoint. When I make the request, the Django API responds with a 401, unauthorized error. If I add token into headers, it works but I don't know if this is the way or I should do in another way: const jwtToken = 'mytoken'; const response = await axios.get("http://localhost:8000/api/hello/", { withCredentials: true, headers: { 'Authorization': `Bearer ${jwtToken}`, } views.py: from rest_framework.views import APIView from rest_framework.response import Response from rest_framework.permissions import IsAuthenticated class HelloView(APIView): permission_classes = (IsAuthenticated,) def get(self, request): content = {'message': 'Hello, World!'} return Response(content) settings.py """ Django settings for backend project.

csrf_exempt true on all callbacks
I've created some custom middleware for my django rest api to enforce a CSRF security policy of setting custom headers. I've subclassed CsrfViewMiddleware and overriden a few methods to suite my needs, most notably the check_token method. However, I noticed later on that all requests have been coming in with the attribute "csrf_exempt" set to true, even though nowhere have I used the csrf_exempt decorator. I've searched through the django docs to try and figure out why this has been happening to no avail. Here is my custom middleware: class CustomCsrfMiddleware(CsrfViewMiddleware): def _reject(self, request, reason): logger.warning("Forbidden (%s): %s", reason, request.path) return Response( {'detail': 'Forbidden', 'reason': reason}, status.HTTP_403_FORBIDDEN ) def _check_token(self, request): # Get the two relevant pieces of information, the # the returned csrftoken in the custom header and the hmac try: hmac = _get_hmac(request) except BadDigest as e: raise RejectRequest(e.reason) try: request_csrf_token = request.META[settings.CSRF_HEADER_NAME] token_source = settings.CSRF_HEADER_NAME except KeyError: raise RejectRequest(REASON_CSRF_TOKEN_MISSING) try: _check_token_format(request_csrf_token) except InvalidTokenFormat as e: reason = self._bad_token_message(e.reason, token_source) raise RejectRequest(reason) if not _does_match(request_csrf_token, hmac): reason = self._bad_token_message("incorrect", token_source) raise RejectRequest(reason) def process_request(self, request): try: csrf_secret = self._get_secret(request) if csrf_secret is None: raise InvalidTokenFormat(REASON_CSRF_TOKEN_MISSING) except InvalidTokenFormat: _add_new_csrf_cookie(request) else: if csrf_secret is not None: request.META["CSRF_COOKIE"] = csrf_secret def … -
Forbidden (Origin checking failed - https://api.example.com does not match any trusted origins.): /admin/login/
I'm running a Django app over DigitalOcean's Kubernetes, the site runs over https but when I try to use the Django Admin from the domain, it throws a 403 forbidden error but if I connect directly to the Pod it succeeds. I wondered if it has to do with the ingress set up that is not recognizing the paths of api.example.com. Here's the ingress.yaml file apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: backend-ingress annotations: kubernetes.io/ingress.class: "nginx" cert-manager.io/cluster-issuer: "letsencrypt-prod" spec: ingressClassName: nginx tls: - hosts: - example.com - api.example.com secretName: tls-secret-name rules: - host: api.example.com http: paths: - pathType: Prefix path: "/" backend: service: name: backend port: number: 8000 - host: example.com http: paths: - pathType: Prefix path: "/" backend: service: name: frontend port: number: 3000 Any clue? -

Can we implement Airflow in a Django project for scheduling tasks?
I'm working on a Django rest project to create different API endpoints. I want to implement airflow that reads a text file and stores it in a Django Model daily. I have installed Apache airflow, created a DAG, and changed my dag location in the airflow.cfg file. But when I run the webserver and the scheduler I cannot see my dag in the DAG's list. Can somebody help me with the airflow django implementation?
