How To booking time (start pm) and (end am)
I am creating a site for booking stadiums by the hour, so the user books the stadium for a period of time, for example: John books Stadium X from 9 pm to 11 pm.... No other user can book the same stadium on the same day and at the same time The code in front of you is working very, very correctly But only one problem happens when the booking starts in the evening and ends in the morning It's when the user, for example: John, books the stadium from 11 pm to 2 am If someone else booked the same stadium on the same day, an example of: Lion makes a reservation for the same stadium from 12 AM to 1 am the system accepts this reservation and does not prevent it (Considering it's considered the same period for user John ) This is not true because there will be more than one user who has booked the same period I don't know the solution my models : class OpeningHours(models.Model): user = models.ForeignKey(User,on_delete=models.CASCADE) pitche = models.ForeignKey(Pitche,on_delete=models.DO_NOTHING) made_on = models.DateField() from_hour = models.TimeField() to_hour = models.TimeField() timing = models.CharField(max_length=50,choices=timing) def __str__(self): return f"{self.pitche}-{self.from_hour} to {self.to_hour}" class Meta : ordering =['-made_on'] … -
Run celery app in django docker container
I have a Django project which uses docker and docker-compose, and I want to use Celery within the Django project. I have followed Celery docs to create an app, a task and connect it with RabbitMQ broker. This is my celery.py file, in the same dir as the settings.py file: import os from celery import Celery # Set the default Django settings module for the 'celery' program. os.environ.setdefault("DJANGO_SETTINGS_MODULE", "proj.settings") backtest_app = Celery("backtest_app") # Using a string here means the worker doesn't have to serialize # the configuration object to child processes. # - namespace='CELERY' means all celery-related configuration keys # should have a `CELERY_` prefix. backtest_app.config_from_object("django.conf:settings", namespace="CELERY") # Load task modules from all registered Django apps. backtest_app.autodiscover_tasks() Also I have set the Celery app config in the settings.py file: # CELERY config CELERY_BROKER_URL = "amqp://rabbitmq:5672" CELERY_BROKER_USER = "user" CELERY_BROKER_PASSWORD = "pass" CELERY_BACKEND = "rpc://" CELERY_BROKER_POOL_LIMIT = 100 CELERY_TASK_DEFAULT_QUEUE = "backtest_queue" CELERY_TASK_DEFAULT_EXCHANGE = "backtest_exchange" CELERY_TASK_DEFAULT_ROUTING_KEY = "backtest_queue" CELERY_ENABLE_UTC = True CELERY_TIMEZONE = "UTC" CELERY_TASK_TRACK_STARTED = True CELERY_TASK_TIME_LIMIT = 30 * 60 CELERY_RESULT_BACKEND = "django-db" CELERY_CACHE_BACKEND = "django-cache" Now, I have this code in the Dockerfile of the backend: FROM python:3.10.8-alpine # Prevents Python from writing pyc files to disc: ENV PYTHONDONTWRITEBYTECODE … -

How do I keep all query parameters intact when changing page in django?
I have this issue with pagination: <a href="{{ request.get_full_path }}{% if request.GET %}&{% else %}?{% endif %}page={{ page_obj.previous_page_number }}">previous</a> It works fine, but every time I click on it it adds one more ?page=1 at the end of URL, so url looks like this after few clicks: example/something?query_params=5&page=1&page=1&page=1&page=1 I know why that happens, it's because I hardcoded it into url, but I have to use get_full_path because I need other query parameters together with page. So basically I want all those query params but WITHOUT page=something being added each time I change page. I need only one page query parameter. -

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.

Regarding the accessing the form field of a django wizard form
`Dear All, I am new to Django and eager to learn it. I have created a Django wizard form with three steps. I defined only one model and separated it into three form classes. Now I want to access these form classes manually to render it into the HTML. But I am not able to do it. Like in the case of forms we can access the files by using the below given syntax. {{all_forms.Participation_Year.label_tag}} {{all_forms.Participation_Year}} I want a similar type of syntax for this. models.py class Test_session(models.Model): Subject_ID = models.CharField(max_length=20) Participation_Year = models.CharField(max_length=20) Phone_Number = models.CharField(max_length=20) Gender = models.CharField(max_length=20) Blood_Group =models.CharField(max_length=20) Age = models.CharField(max_length=20) DOB = models.CharField(max_length=50) POB = models.CharField(max_length=100) City = models.CharField(max_length=100) District = models.CharField(max_length=100) views.py class MyWizard(SessionWizardView): form_list = [Step1Form, Step2Form, Step3Form] # List of forms for each step template_name = 'participants/test_session.html' # Create a template for your multi-page form #print(len(form_list)) def done(self, form_list, **kwargs): # Collect data from each form step data = {} for i, form in enumerate(form_list): data.update(form.cleaned_data) print(f"Step {i+1} data:", form.cleaned_data) # Create a new instance of your model and save the data form_data = Test_session(\*\*data) # form_data.save() # Redirect to a thank you page or another URL return HttpResponseRedirect('/thank-you') urls.py path('my-form/', MyWizard.as_view(), … -
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? -
