Django Rest Framework authentication class override request.user
in my django App I have created a custom Authentication class using rest_framework: from business.models import BusinessToken from rest_framework.authtoken.models import Token from rest_framework import authentication, exceptions class AuthenticationMixin(authentication.BaseAuthentication): def authenticate(self, request): raw_token = request.META.get('HTTP_AUTHORIZATION') if not raw_token: return None token_key = raw_token.replace("Token ", "") user_token = Token.objects.filter(key=token_key).first() if user_token is not None: user = user_token.user request.user = user return user, None business_token = BusinessToken.objects.filter(key=token_key).first() if business_token is not None: business = business_token.business request.business = business user = business.owner request.user = user return business, None raise exceptions.AuthenticationFailed('No such user or business') As you can see the class has to authenticate the user or the business based on the token pass from http request. If the user authenticate itself through the business token in the api view I have to access to request.user as the business.owner and request.business as the business, but request.user is set to business, it's override somewhere. -

Django Many to Many (through) with three tables and extra attributes
I have an already existing database with 3 tables: Person, Card, and Permission. A user may have access to multiple cards, of which only some is owned by the person. How would I get all cards that the person has access to with the ownership status? Due to how the system should work, it's essential that the DB fetch is done in a single query. It's as if the usage of some magic values (such as objects.<table_name>_set....) is necessary to get this working? Ideal target query (including the person table) would be: SELECT card.id, card.text, permissions.owner FROM person.id JOIN permissions ON person.id = permissions.person_id JOIN cards.id = permissions.card_id WHERE person.id = <some person id>; Example target result from the query fetching cards for user id=1: [ { "id": 123, "text": "some random text", "owner": false }, { "id": 682, "text": "more random text", "owner": true } ] I've also tried some other solutions in some other threads, but most of them either don't include the extra data from the through-table, or don't work as they seem to require an extra table (such as Many-to-many relationship between 3 tables in Django which will throw an error "relation personcardpermissions does not exist" … -
How to implement consumer for voice chat app on Django?
I am currently working on a voice chat app as a personal project and this app will be like Discord, where users can hop into a chat room and start talking to people in that room. I am only going to make it voice only for now (I will implement text messaging later). I have been looking at examples on Github and I am having a little trouble with how to make the Consumer. Here is what I have right now: import json from asgiref.sync import async_to_sync from channels.generic.websocket import WebsocketConsumer class VoiceConsumer(WebsocketConsumer): def connect(self): self.room_name = self.scope['url_route']['kwargs']['room_name'] self.room_group_name = "chat_%s" % self.room_name # join the room async_to_sync(self.channel_layer.group_add)( self.room_group_name, self.channel_name ) self.accept() def disconnect(self, closed_code): async_to_sync(self.channel_layer.group_discard)( self.room_group_name, self.channel_name ) def receive(self, text_data): text_data_json = json.loads(text_data) # Ask about this, how to receive voice ? voice_message = text_data_json['message'] async_to_sync(self.channel_layer.group_send)( self.room_group_name, {'type' : 'chat_message', 'message': voice_message} ) As you see, I am confused about the text_data_json['message'] part. This is based off an example I have seen where someone implements messages, but I want to implement voice only. What do I change about this to where I can implement voice only ? text_data_json = json.loads(text_data) # Ask about this, how to receive voice … -

Django override save method for resize image only works forn one function. Why is this happening?
I got those two functions in my Model but only the cover_photo one is working. class UserProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, blank=True, null=True) profile_picture = models.ImageField(upload_to='users/profile_pictures', blank=True, null=True) cover_photo = models.ImageField(upload_to='users/cover_photos', blank=True, null=True) ... def save(self, *args, **kwargs): super().save(*args, **kwargs) if self.profile_picture: img = Image.open(self.profile_picture.path) if img.height > 50 or img.width > 50: new_height = 100 new_width = int(new_height / img.height * img.width) img = img.resize((new_width, new_height)) img.save(self.profile_picture.path) def save(self, *args, **kwargs): super().save(*args, **kwargs) if self.cover_photo: img = Image.open(self.cover_photo.path) if img.width > 100 or img.height > 100: new_width = 600 new_height = int(new_width / img.width * img.width) img = img.resize((new_height, new_width)) img.save(self.cover_photo.path) If i swap then, only the profile_picture works but the other one stops. Does any one have any idea why this happens? Is there a way to make both works. Thank you very much! -
I have 69 Heads in git. I don't see recent commits on reflog. How can I find recent commits?
My Problem in Git Bash is that the most recent version that I can find is Head@{0} and is 2 months old. When running recent commits the feed back stated that everything was up to date. Is there anywhere my recent commits might be? I looked into the history and cannot find commits that I made just last night. I had been trying git push to send my commits to Github but it did not work the last couple of times I tried. I pulled the file from Github and now my program is as it was 2 months ago. I have 69 Heads and cannot find any sha that contains new versions. I tried the Github desktop program and cannot find any recent commits there either. I did not have any branches going at the time. -

Django adds quotes in template to each TextField. How to get rid of them?
I have some TextFields in my MySQL Database, like: body = models.TextField(default = 'initial') When I call out it in my template doing this: <p class = "service_description"> {{ post.body }} </p> I get this: <p class = "service_description"> " This is the text from the database, but it is with 2 quotes and 2 spaces around itself.

I also tried to add {% autoescape off %} {{ post.body }} {% endautoescape %} it doesn't help as well. Please let me know, why do I get these excess quotes and how to remove them correctly without slicing? Thanks. -

I have been trying for days to solve the following issue. I cannot make container A expose port for container B in docker compose. The two containers, however, can ping the other (so they are on the same network e.g. ping db from Container B resolves the IP). Example: Container A: postgres (exposes port 5432) Container B: django project (trys to connect to postgres on port 5432) django.env DB_NAME=freelancetracker DB_USER=freelance DB_PASSWORD=freelance1234 DB_HOST=postgresdb DB_PORT=5432 postgres.env POSTGRES_PASSWORD=freelance1234 POSTGRES_USER=freelance POSTGRES_DB=freelancedb version: "3.9" services: db: image: postgres env_file: - postgres.env ports: - 9001:5432 environment: - "POSTGRES_HOST_AUTH_METHOD=trust" volumes: - ./data/db:/var/lib/postgresql/data web: build: context: . network: host args: progress: plain volumes: - .:/code ports: - 9101:9100 env_file: - django.env depends_on: - db Container postgres: { "Id": "sha256:680aba37fd0f0766e7568a00daf18cfd4916c2689def0f17962a3e1508c22856", "RepoTags": [ "postgres:latest" ], "RepoDigests": [ "postgres@sha256:901df890146ec46a5cab7a33f4ac84e81bac2fe92b2c9a14fd649502c4adf954" ], "Parent": "", "Comment": "", "Created": "2023-02-11T05:02:41.267291947Z", "Container": "7f186dd9993cc4c4ee68d8e17c42f9205a5b09b06131c62d79861b85ff4aec1d", "ContainerConfig": { "Hostname": "7f186dd9993c", "Domainname": "", "User": "", "AttachStdin": false, "AttachStdout": false, "AttachStderr": false, "ExposedPorts": { "5432/tcp": {} }, "Tty": false, "OpenStdin": false, "StdinOnce": false, "Env": [ "PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/lib/postgresql/15/bin", "GOSU_VERSION=1.16", "LANG=en_US.utf8", "PG_MAJOR=15", "PG_VERSION=15.2-1.pgdg110+1", "PGDATA=/var/lib/postgresql/data" ], "Cmd": [ "/bin/sh", "-c", "#(nop) ", "CMD [\"postgres\"]" ], "Image": "sha256:073c3dc2528e2f091ce4497b9f51f4a69105de3faff43bd8675b99c5c2e470a6", "Volumes": { "/var/lib/postgresql/data": {} }, "WorkingDir": "", "Entrypoint": [ "docker-entrypoint.sh" ], "OnBuild": null, "Labels": {}, "StopSignal": "SIGINT" }, … -
