Django CSRF Token is not getting set
So i am using VueJS and Django. Axios to make a get request. When i try to retrieve the CSRF token and log it, it shows me it is null. here is my serializer: class VehicleSerializer(serializers.ModelSerializer): seller = serializers.SerializerMethodField() class Meta: model = Vehicle fields = ('vehicle_id', 'color', 'model', 'year', 'category', 'manufacturer', 'seller') def get_seller(self, instance): return instance.seller.customer.username My Viewset: class VehicleListCreateAPIView(ListCreateAPIView): serializer_class = VehicleSerializer permission_classes = [IsAuthenticated] queryset = Vehicle.objects.all() def perform_create(self, serializer): request_user = self.request.user try: seller = Seller.objects.get(customer = request_user) except Seller.DoesNotExist: seller = Seller.objects.create(customer = request_user) serializer.save(seller = seller) My urlpattern: path('vehicles/', VehicleListCreateAPIView.as_view()), The code from django documentation to retrieve a token: function getCookie(name) { var cookieValue = null; if (document.cookie && document.cookie !== '') { var cookies = document.cookie.split(';'); for (var i = 0; i < cookies.length; i++) { var 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; } var csrftoken = getCookie('csrftoken'); export { csrftoken }; -
Django admin page and CSS
I'm very new to django. I just did the very basic step for creating a project which has one application. I started the server using python manage.py runserver which ended up giving me my home page. but when I opened the admin page it was not with proper CSS as it is supposed to be. I went through some solutions like adding the following code so that my static files are added correctly. STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATIC_URL = '/static/' But this doesn't reflect anything after running python manage.py collectstatic. Do I need something else to done further? This is the settings.py file import os # Build paths inside the project like this: os.path.join(BASE_DIR, ...) BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) # Quick-start development settings - unsuitable for production # See https://docs.djangoproject.com/en/3.0/howto/deployment/checklist/ # SECURITY WARNING: keep the secret key used in production secret!

Django IIS Active Directory Single Sign On (SSO)
I have application written in Django, hosted with IIS on my intranet with Active Directory. Following this stackoverflow topic https://stackoverflow.com/a/26987622/4992056 I managed to create basic domain authentication. Unfortunately this solution reqiures login with domain account credentials everytime I rerun browser what is not ideal user experience and brings security issues (browser prompts user to save their domain account credentials). I would like to have true single sign-on feature that means: when user is signing in with his domain account, he/she should also be signed in to the web app without prompting for password. Thanks in advice for your answers. Best regards, Wojtek -

Django channels page stuck on loading
I created a simple Django Channels consumer that connects to a Redis channel and receives some data from this channel, i want to send this data to the frontend. The consumer is able to connect to the consumer and receives the data; the problem is that if i try to load the page when the consumer is running, the page will be stuck on loading. I'm sure this happens because the connection to the Redis channel is a blocking operation, or it could be a problem with threads. I'm new to this concepts, so i decided to make a question for it. Here is my consumer: class EchoConsumer(AsyncConsumer): async def websocket_connect(self, event): self.send({ 'type': 'websocket.accept' }) self.receive(event) def receive(self, event): channel = 'TEST' params = urllib.parse.parse_qs(self.scope.get('query_string', b'').decode('utf-8')) pubsub = connection.pubsub(ignore_subscribe_messages=True) pubsub.subscribe(channel) for message in pubsub.listen(): # self.send({ # 'type': 'websocket.send', # 'text': message['data'], # }) print(message['data']) async def websocket_disconnect(self, event): redis_url = 'redis://localhost:6379/0' connection = redis.StrictRedis.from_url(redis_url, decode_responses=True) channel = 'TEST' pubsub = connection.pubsub(ignore_subscribe_messages=True) pubsub.unsubscribe(channel) print('DISCONNECTED!')

Django view as API with Get method save twice records from Firefox
I made a simple view for searching one product in my ecommerce website.. The view (an API) wait a GET parameter (as http://example.com/search/12345) after I would like to save the searched parameter (with a create queryset) in a specific model for obtain search history. But if I call the view/api from last Firefox version, I get two records in database, from Edge only one. Deepening the topic the problem is the idempotency expected from HTTP RFC on Get method. Some browsers can do more than one request... I need to preserve GET method for search api but I need saving the searched string. What I can use GET parameter for searching and SAVE it in database only one? without CSRF/Cookie/User-Agent? P.S. I don't post code because it is needless. -

Django admin Form with dynamic field addition
I study in Django and I have a task. There is data with a list of periods. These periods can be either five or twenty. And I need to create a form in to add this data. Periods will be added using the two fields start_period and end_period. The task is that when adding data, the user in the admin panel could add periods as much as necessary, when changing data accordingly, too. I see this as a form with the ability to dynamically add the required number of fields start_period and end_period, then saving data with periods in either json or in a separate table, the problem is that I don’t know how to implement dynamic adding of a field. Unfortunately, I could not find an adequate solution to this problem. I found something close to this through Formsets, but this is not what we are looking for. Who can tell how to implement this? python 3.7, Django 3.0.4 -

Updating value of a model
I am newbie of Django. And I don't understand how Django model works. First, I am trying to create a model of user score in users/models.py, so each user has a score variable to store their own score, and score can be updated. Then, in my morse_logs/game1.html, i will ask a question as simple as 1+1 to user, then i retrieve the answer and compare it in morse_logs/views.py to see if it is correct, if it is correct, I will add 5 score to that user; if incorrect, no score is added. So now I am struggling to define a correct model for setting a field for user to have their own score, and I wonder how can I update and retrieve the score of the user in view.py. users/models.py from django.db import models from django import forms from django.contrib.auth.models import User from django.db.models.signals import post_save # Create your models here. class UserProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) description = models.CharField(max_length=100, default='') #score = models.CharField(User, max_length=10, default=0) def create_profile(sender, **kwargs): if kwargs['created']: user_profile = UserProfile.objects.create(user=kwargs['instance']) post_save.connect(create_profile, sender=User) class UserScore(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) score = models.CharField(max_length=1000, default=0) date_added = models.DateTimeField(auto_now_add=True) def __str__(self): """Returns a string representation of the model""" return …
