Getting 401 unauthorised when trying to access JWT authenticated page in Django even after generating token
I'm a student trying to teach myself JWT authentication. I created a basic log in page and after logging in the user should see a welcome page that says Welcome {username}. However even after logging in, the welcome page says Welcome GET /welcome/ HTTP 401 Unauthorized Allow: GET, OPTIONS Content-Type: application/json Vary: Accept WWW-Authenticate: Bearer realm="api" { "detail": "Authentication credentials were not provided." } My code looks like this: views.py from django.http import JsonResponse from django.shortcuts import render, redirect from loginapp.models import User from rest_framework.decorators import api_view, permission_classes, authentication_classes from rest_framework.permissions import IsAuthenticated from rest_framework.response import Response from rest_framework_simplejwt.tokens import RefreshToken from django.contrib.auth import authenticate from rest_framework_simplejwt.authentication import JWTAuthentication from django.urls import reverse def login(request): if request.method == 'POST': username = request.POST.get('username') password = request.POST.get('password') print("Username:", username) print("Password:", password) user = User.objects.filter(username=username).first() #user = authenticate(username=username, password=password) if user is not None and user.password == password: refresh = RefreshToken.for_user(user) token = str(refresh.access_token) response = JsonResponse({'message': 'Login successful'}) response['Authorization'] = f'Bearer {token}' return response else: return JsonResponse({'error_message': 'Invalid username or password.'}, status=400) else: return render(request, 'login.html') @api_view(['GET']) @permission_classes([IsAuthenticated]) def welcome(request): username = request.user.username return Response({'message': f'Welcome, {username}!'}) my urls.py looks like this: from django.urls import path from loginapp import views from rest_framework_simplejwt.views … -

Django annotate over multi records forignkeys
I Work on a KPI system in which every manager can put specific questions for each user and answer them every month from 1 to 10 we have 4 departments, and every department says to have 4 question these answers have to be calculated to return the % number for each department Models # question to answer every month class Question(models.Model): department = models.CharField(max_length=100, choices=USER_TYPE) question = models.CharField(max_length=100) def __str__(self): return f"{self.question}" # create every 01-month celery class Kpi(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, related_name="kip_for") created_at = models.DateField() class Meta: unique_together = ("user", "created_at") def __str__(self): return f"{self.user} for Month {self.created_at.month}" # group the answers by department class DepartmentsKPI(models.Model): department = models.CharField(max_length=100, choices=USER_TYPE) kpi = models.ForeignKey( Kpi, on_delete=models.CASCADE, related_name="department_kpi" ) class Answer(models.Model): question = models.ForeignKey( Question, on_delete=models.CASCADE, related_name="answer_for" ) score = models.PositiveSmallIntegerField(default=0) comment = models.TextField(null=True, blank=True) kpi_answers = models.ForeignKey( DepartmentsKPI, on_delete=models.CASCADE, related_name="department_answers", ) the problem is when I apply the annotation over the KPI model to sum the answer score for each department, the result becomes ungrouped so I have to group them by a unique value in my case the username def get_kpi_range(*, year, month): queryset = ( KPIRepository.filter_kpis( created_at__year=year, created_at__month=month, ) .prefetch_related("department_kpi__department_answers") .annotate( score=Sum("department_kpi__department_answers__score") / Count("department_kpi__department_answers"), department=F("department_kpi__department"), ) .values("id", … -

How to Clean an Ubuntu Server Previously Used for Hosting a Django Project?
I have an Ubuntu server that previously hosted a Django project. I want to clean the server and prepare it for a new project deployment. This includes removing all project-specific files, configurations, and any leftover services related to the old project. Ideally, I'd like to get the server close to its initial state (without reinstalling the OS). I followed the documentation provided by DigitalOcean to set up Django with Postgres, Nginx, and Gunicorn on Ubuntu for the old project. However, now I need to remove all traces of the old project from the server. I'm expecting guidance on how to properly clean up the server, including removing project files, configurations, and services, without affecting the OS or other applications running on the server. DigitalOcean documentation -
Errors with Django 4.2 and Spatialite 5
I am upgrading an application from Django 3.2 to 4.2, which uses postgis in production, and spatialite when running unit tests. Running the tests on this application, I'm getting this error: django.db.utils.OperationalError: error in trigger ISO_metadata_reference_row_id_value_insert: no such column: rowid make: *** [django.mk:49: test] Error 1 This problem is documented in this ticket, and seems to be an issue with using Django 4.2 and Spatialite 5: https://code.djangoproject.com/ticket/32935 One of the workarounds looks like executing this command in the spatialite database: ./manage.py shell -c "import django;django.db.connection.cursor().execute('SELECT InitSpatialMetaData(1);')"; However, after I run this command, I am still getting the no such column: rowid error. Has anyone else run into this? I am using Django 4.2.11, sqlite 3.42.0, libspatialite 5.0.1, python 3.12.2 on Fedora Linux. -

Why the data batch size for loop failing for Insert API in python Django?
We are using 3rd party API to pull data and enabled pagination, hence the amount of data coming in are huge. Some times 12000 records at a time in a list. We are using mySQL DB, and it fails when it receives that amount of data at a time. So, as temporary solution I wanted to implement the "batch size" concept as below: batch_size = 3 for batch in range(0, len(payload), batch_size): batch_data = payload[batch:batch + batch_size] Below is the POST method code snippet where we are getting the data source and its format , and how I am passing it. def post(self, request): data = fetch_data.get(request=request) try: if data.status_code == status.HTTP_200_OK: payload = data.data payload["token_id"] = token_id payload["org"] = org api_log( msg=f"TOtal cont data from xyz : {json.dumps(payload)}" ) api_log( msg=f"Size of cont data from xyz : {len(json.dumps(payload))}" ) api_log( msg=f"Length of cont data to db: {len(payload)}" ) api_log( msg=f"Total cont data to DB: {payload}" ) url = ("http://example.com") batch_size = 3 api_log(msg=f"[BATCH SIZE]:: {batch_size}") for batch in range(0, len(payload), batch_size): api_log(msg=f"[BATCH SIZE]:: {batch_size}") api_log(msg=f"[BATCH]:: {batch}") batch_data = payload[batch:batch + batch_size] api_log(msg=f"[BATCH DATA]:: {batch_data}") response_data = requests.post( url, json=batch_data, ) if response_data.status_code == status.HTTP_201_CREATED: api_log( msg="data inserted successfully" ) … -
Django Rest API - handling max_decimal_places more gracefully
Using Django Rest Framework and having a model that contains a decimal field like this: rate = models.DecimalField(max_digits=7, decimal_places=2) If a rate value is submitded with more than 2 decimal places I get a validation error with code "max_decimal_places". I would like to handle things more gracefully and instead of raising an error I would like to round the rate to 2 decimal places. What's the best or even a good way of doing this. Overriding validation? Other options? Thanks Stephan -
Django PyCryptodome AES decryption - ValueError: Padding is incorrect
I am trying to encrypt incoming files and than decrypt them later. I was following the documentation for how to use AES with CBC mode for decryption and encryption. My view for uploading and encrypting file: @router.post("/upload_files") def upload_files(request, file: UploadedFile = File(...)): save_file = operations.aes_encryption(user_id=request.auth.id,file=request.FILES.get('file')) def aes_encryption(self,user_id,file): user = UserQueries.get_user(id=user_id) key: bytes = bytes(user.key, "utf-8") path: str = user.path save_file = self._encrypt_file(file,key,path,user) return save_file def _encrypt_file(self,file,key,path,user): file_content = file.read() cipher = AES.new(key, AES.MODE_CBC) ct_bytes = cipher.encrypt(pad(file_content, AES.block_size)) iv = b64encode(cipher.iv).decode('utf-8') ct = b64encode(ct_bytes).decode('utf-8') with open(str(settings.BASE_STORAGE_DIR)+"/"+path+file.name,"wb") as f: f.write(ct.encode('utf-8')) return save_metadata This code works like it should it encrypts the file and stores it in directory.

Wagtail: include custom form in SnippetsViewSet
I'am trying to include a custom form in the SnippetsView of one of my models.The form's purpose is to let the user upload a csv-file to add Data, the model in question has a one-to-many relationship with a second model, which is then bulk-updated with the data from the csv-file. Th goal is that for very view of every instance of the model generated via the SnippetViewSet the form can be found and used in a seperate Tab created via TabbedInterface. I can of course add manually a form via @hooks.register in a SubMenuItem or I can just add a new FileField to my model and add a hook or overide the models's save method, so that if the user uploads a file in the wagtail-admin it will get used to update the second model. I'd like rather to know wether there is a simple way to add a custom form to a SnippetView without having to subclass wagtail.snippets.views.snippets.EditView and CreateView and creating a new template or at least one not involving to much ducktaping. Currently I can upload the model via csv in the django-admin. But I'd like that to be possible in wagtail-admin as well. -

This is the detailed error I'm encountering while hitting the API in Postman: Internal Server Error: /api/token/ Traceback (most recent call last): File "C:\Users\kalash bhagwat\Desktop\Copods\Cloned Repos\leave-tracking-tool-backend\.venv\lib\site-packages\django\core\handlers\exception.py", line 55, in inner response = get_response(request) File "C:\Users\kalash bhagwat\Desktop\Copods\Cloned Repos\leave-tracking-tool-backend\.venv\lib\site-packages\django\core\handlers\base.py", line 197, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "C:\Users\kalash bhagwat\Desktop\Copods\Cloned Repos\leave-tracking-tool-backend\.venv\lib\site-packages\django\views\decorators\csrf.py", line 56, in wrapper_view return view_func(*args, **kwargs) File "C:\Users\kalash bhagwat\Desktop\Copods\Cloned Repos\leave-tracking-tool-backend\.venv\lib\site-packages\django\views\generic\base.py", line 104, in view return self.dispatch(request, *args, **kwargs) File "C:\Users\kalash bhagwat\Desktop\Copods\Cloned Repos\leave-tracking-tool-backend\.venv\lib\site-packages\rest_framework\views.py", line 509, in dispatch response = self.handle_exception(exc) File "C:\Users\kalash bhagwat\Desktop\Copods\Cloned Repos\leave-tracking-tool-backend\.venv\lib\site-packages\rest_framework\views.py", line 469, in handle_exception self.raise_uncaught_exception(exc) File "C:\Users\kalash bhagwat\Desktop\Copods\Cloned Repos\leave-tracking-tool-backend\.venv\lib\site-packages\rest_framework\views.py", line 480, in raise_uncaught_exception raise exc File "C:\Users\kalash bhagwat\Desktop\Copods\Cloned Repos\leave-tracking-tool-backend\.venv\lib\site-packages\rest_framework\views.py", line 506, in dispatch response = handler(request, *args, **kwargs) File "C:\Users\kalash bhagwat\Desktop\Copods\Cloned Repos\leave-tracking-tool-backend\.venv\lib\site-packages\rest_framework_simplejwt\views.py", line 44, in post serializer.is_valid(raise_exception=True) File "C:\Users\kalash bhagwat\Desktop\Copods\Cloned Repos\leave-tracking-tool-backend\.venv\lib\site-packages\rest_framework\serializers.py", line 223, in is_valid self._validated_data = self.run_validation(self.initial_data) File "C:\Users\kalash bhagwat\Desktop\Copods\Cloned Repos\leave-tracking-tool-backend\.venv\lib\site-packages\rest_framework\serializers.py", line 445, in run_validation value = self.validate(value) File "C:\Users\kalash bhagwat\Desktop\Copods\Cloned Repos\leave-tracking-tool-backend\.venv\lib\site-packages\rest_framework_simplejwt\serializers.py", line 77, in validate data["refresh"] = str(refresh) File … -

Django guest user cart functionality? Is it safe?
Creating an e-commerce website project to try and learn Django and more about Javascript, so I have been going over a tutorial for the past week. In the tutorial, there is a guest user cart feature. It works by storing user and product data into the cookies. Though, I am having trouble getting it to add multiple of the same item. If I were to login as a user the website works fine. The remove feature works fine for deleting an item out of the cart as guest. In the JavaScript console, the items in the cart get deleted, but the cookies retain the same information before the website reloads. Don't know the cause for this issue. I would really like this feature to work out. JavaScript Console Log cart.js var updateBtns = document.getElementsByClassName('update-cart') for(var i = 0; i < updateBtns.length; i++) { updateBtns[i].addEventListener('click', function() { //sets variable to add to the dictionary. var productId = this.dataset.product var action = this.dataset.action console.log('productId:', productId, 'action:', action) //checks to see if the user is logged in. console.log('USER:', user) if (user === 'AnonymousUser') { addCookieItem(productId, action) } else { updateUserOrder(productId, action) } }) } function addCookieItem(productId, action) { console.log('Not logged in.') //add quantity … -

Deployed Django Application on PythonAnywhere: Connection Refused Error When Controlling Raspberry Pi Robot Remotely
I am trying to deploy a Django web application on PythonAnywhere that controls a Raspberry Pi robot remotely. The application worked flawlessly locally using ngrok to establish a connection, but after deploying it to PythonAnywhere, I encountered the following error: 2024-04-17 07:49:53 Connection refused: The server is not accepting connections. I tried: Added localhost to the ALLOWED_HOSTS in Django settings. Tried running the server on a different port. Disabled the firewall on the Raspberry Pi. Added corsheaders to the Django project.
