TypeError: decode() got an unexpected keyword argument 'verify' djangorestframework simple jwt
I'm using djoser for authentication and I'm getting TypeError: decode() got an unexpected keyword argument 'verify'. The /jwt/create/ endpoint is working and returning the access and refresh tokens but I can't verify or get the user's details (/auth/users/me/). The same code works in my previous project.

Creating months based on start date and end date value in django
I have been working on an application where user is required to create monthly tasks, so I made a model named AcademicYear and Months, now I want to take only the start_month and end_month input from user, and based upon the values of these fields, I want to create months automatically once the year object is create. class AcademicYear(SingleActiveModel, models.Model): title = models.CharField(max_length=10) start_month = models.DateField() end_month = models.DateField() def __str__(self): return str(self.title) class Months(models.Model): year = models.ForeignKey(AcademicYear, on_delete = models.PROTECT, related_name='year') months = models.CharField(max_length = 20) ??? what could be the logic or a solution which can be applied here? -

Nginx not finding static files in Dockered Django app in Azure Web App for containers
I managed to run my Django app locally with docker compose( Django container + Nginx container) and it works fine, but when i want to run it in Azure web app for containers nginx can't find the ressources. I don't know if i should change some configuration so it can work in Azure services or i need to enable ports in azure app settings therefore my containers could communicate. This is my nginx configuration (nginx.conf) : upstream myapp { server web:8000; } server { listen 80; server_name myappname.azurewebsites.net; location / { proxy_pass http://myapp; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $host; proxy_redirect off; } location /static/ { alias /home/app/web/static/; } location /media/ { alias /home/app/web/media/; } } I don't know why it did work locally when i run docker compose but in azure web app nginx can't find static files. Please let me know if I need to clarify or include anything else. Thanks in advance. -
Why django channels are not receiving headers?
I am trying to code simple python websocket client that will communicate with django channels. I am using python websockets library to achieve that.

Google Calendar API authorization working on localhost but not on Heroku
I want to use the Google Calendar API for my Django application. I have followed the instructions here: https://karenapp.io/articles/how-to-automate-google-calendar-with-python-using-the-calendar-api/ I have also added the redirect uri's in Google API - seems like a browser tries to open up on the server side (as it does on local, but I am unable to manipulate it as the browser from the server side does not show up).

OIDC with Keycloak and Django - Missing States
I'm attempting to set up OIDC with Keycloak as my IdP and Django (using Django Rest Framework and mozilla-django-oidc) as my client server. I have got keycloak installed and a rough Django application stood up that successfully redirects to keycloak where I can then successfully authenticate (to keycloak), but when I'm redirected back to django I'm missing information, specifically oidc_states. The redirect to django triggers this log entry: [12/Oct/2021 08:28:06] "GET /api/oidc/callback/?state=QGsO26esqdtHZcsfRfYoXvUy0QWcGdZv&session_state=493887a4-600e-4dd2-aaaf-4134ea671c9a&code=dfe1573e-cf8e-4829-8874-a3500ba63712.493887a4-600e-4dd2-aaaf-4134ea671c9a.c1dfdb46-140c-4ccd-8308-6db3b468346a HTTP/1.1" 302 0 This contains three keys: state, session_state, and code. The default callback view provided by mozilla-django-oidc contains this: def get(self, request): """Callback handler for OIDC authorization code flow""" if request.GET.get('error'): if request.user.is_authenticated: auth.logout(request) assert not request.user.is_authenticated elif 'code' in request.GET and 'state' in request.GET: if 'oidc_states' not in request.session: return self.login_failure() # ... Because keycloak isn't making the redirect with oidc_states added, this is immediately failing and I haven't been able to figure out why. I'm guessing that the problem is with my keycloak client configuration? -

Caching authentication result in django-rest-framework-jwt
I`m using Auth0 authentification in a webapp / django-server combination. Auth0 is not the fastest auth framework, it always takes 200ms to authenticate. My webapp sends a lot of requests to the django server, so I thought about caching the authentication for a few seconds. This improves the speed of my app a lot. Is this a good way? Do you see any disadvantages / security issues in doing it this way? django config: REST_FRAMEWORK = { (...) 'DEFAULT_AUTHENTICATION_CLASSES': ( (...) 'rg_auth.rest_framework_authentication_classes.RgJSONWebTokenAuthentication', (...) ), (...) } authentication class: import hashlib from rest_framework_jwt.authentication import JSONWebTokenAuthentication from rest_framework.authentication import get_authorization_header from django.core.cache import cache class RgJSONWebTokenAuthentication(JSONWebTokenAuthentication): def authenticate(self, request): # Get from cache cache_key = self._rg_get_cache_key(request) cached_user_payload_tuple = cache.get(cache_key) # Is cache set? if cached_user_payload_tuple: # Cache is set: Return user/payload tuple return cached_user_payload_tuple else: # Cache is not set: Authenticate and save tuple to cache for 10 seconds user_payload_tuple = super().authenticate(request) if user_payload_tuple: # Set cache cache.set(cache_key, user_payload_tuple, 10) # Return tuple return user_payload_tuple def _rg_get_cache_key(self, request): auth_header = get_authorization_header(request) auth_header_md5 = hashlib.md5(auth_header).hexdigest() return "RgJSONWebTokenAuthentication_{}".format(auth_header_md5) -

receiver is not working in django signals
I've tried to implement django signal's m2m_changed from the documentation here https://docs.djangoproject.com/en/3.2/ref/signals/#django.db.models.signals.m2m_changed Whenever I add/remove new position from the admin panel, the total_price is supposed to change by using signal receiver.
