I'm trying to use Nginx to reverse proxy some applications to different subdomain, the problem is when I try to do this with a Django application it doesn't work well, I get the message that the path does not exist or 404 Page not found. this is a pice of my docker-compose.yaml version: "3.9" services: ww4api: build: . hostname: ww4api command: gunicorn --bind 0.0.0.0:8000 authApi.wsgi --workers=4 depends_on: - db - orion restart: always container_name: ww4api environment: - WW4API_ALLOWED_HOSTS=ww4,ww4api,localhost ports: - 8000:8000 volumes: - .:/app pgadmin: container_name: pgadmin image: dpage/pgadmin4 hostname: pgadmin restart: always depends_on: - timescale environment: - PGADMIN_LISTEN_PORT=5050 nginx: hostname: nginx build: settings/nginx restart: always ports: - 80:80 - 434:434 tty: true volumes: - ./data-models/context:/srv/ww4/context - ./syncthingFolder/Sync:/srv/ww4/projects - ./:/srv/ww4 networks: - default and this is part of my nginx.config worker_processes auto; events { worker_connections 1024; } http { include /etc/nginx/mime.types; server_tokens off; upstream ww4api { server ww4api:8000; } upstream mintaka { server mintaka:8080; } server { listen 80; root /srv/ww4; index index.html; keepalive_timeout 1s; keepalive_requests 5000; location / { try_files $uri $uri/ =404; } location /pgadmin4/ { resolver 127.0.0.11 ipv6=off; proxy_pass http://pgadmin:5050/; proxy_set_header X-Script-Name /pgadmin4; proxy_set_header X-Scheme $scheme; proxy_set_header Upgrade $http_upgrade; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_redirect off; … -
Django "AND" query: Reverse ForeignKey or ManyToMany giving an unexpected result
I found a different result on an "AND" query depending if it was a reverse of forward query. In a FORWARD query you can do this: Model.objects.filter(x=1) & Model.objects.filter(y=2) Model.objects.filter(x=1, y=2) Model.objects.filter(Q(x=1) & Q(y=2)) All give the same result: a QuerySet that satisfies both conditions (x=1 and y=2). But If I have a REVERSE FOREIGNKEY or MANY TO MANY “AND” query something different happens. This is what I did and expect. I have these models: class Blog(models.Model): name = models.CharField(max_length=100) tagline = models.TextField() class Author(models.Model): name = models.CharField(max_length=100) country = models.ForeignKey(Country, on_delete=models.CASCADE) class Entry(models.Model): blog = models.ForeignKey(Blog, on_delete=models.CASCADE) headline = models.CharField(max_length=255) body_text = models.TextField() pub_date = models.DateField() authors = models.ManyToManyField(Author) And let's say I have this data: Headline Pub Date Year Authors Blog Pop 1 2023 Juan Pop Pop 2 2023 Emma Pop Pop 3 2010 Juan, Walmer Pop Other 2023 John Beatles I want to make an “AND” query to get the authors that satisfy both the headline that contains the word “Pop” and Pub Date Year equal to 2023. Expected result: Juan and Emma. Headline Pub Date Year Authors Blog Pop 1 2023 Juan Pop Pop 2 2023 Emma Pop We can use the following methods: Multiple Arguments … -

Accessing Continuous Data from Websockets in Django Channels
Improved Question: In the file "apisGo.py", I have two methods that retrieve data from servers through websockets. This data is updated continuously, meaning the function never ends. The issue is that I need to receive the contents of the "msg" variable from both "apiA" and "apiB" in my "WSConsumer" class, so I can send it to the frontend. What is the correct way to do this? file apisGo.py async def apiA(): async with websockets.connect('wss://ws-api...)) as ws: msg = {"id": "%s" % (uuid), "type": "", "topic": "", "response": True} msg = json.dumps(msg) await ws.send(msg) while True: msg = await ws.recv() async def apiB(): async with websockets.connect('wss://ws-api...)) as ws: msg = {"id": "%s" % (uuid), "type": "", "topic": "", "response": True} msg = json.dumps(msg) await ws.send(msg) while True: msg = await ws.recv() async def main(): task1 = asyncio.create_task(apiA()) task2 = asyncio.create_task(apiB()) await asyncio.gather(task1, task2) if __name__ == "__main__": asyncio.run(main()) file "consumers.py": import apisGo class WSConsumer(WebsocketConsumer): def connect(self): self.accept() asyncio.run(apisGo.main()) I considered using global variables in the "apisGo.py" file and using the "import multiprocessing" in "consumers.py" to create two routines: one to initiate the requests "asyncio.run(apisGo.main())" and another to access the global variables.

Django ORM dublicate objects in queryset after order_by by foreignkey field
I have encountered some unexpected sorting behaviour with objects. As soon as I sort by the related model field, I get duplicates. A short description of the model fields models.py class GoogleCreativeSpend(models.Model): creative = models.ForeignKey( 'GoogleCreative', on_delete=models.CASCADE, ) spend = models.DecimalField() class GoogleCreative(CreamCreative): ..... Create some objects: >>> creative = GoogleCreative.objects.get(name='gs_video1031v1') >>> spend = GoogleCreativeSpend(creative=creative, spend=100,) >>> spend.save() >>> spend = GoogleCreativeSpend(creative=creative, spend=1100,) >>> spend.save() >>> spend = GoogleCreativeSpend(creative=creative, spend=1,) >>> spend.save() views.py queryset = GoogleCreative.objects.all() queryset.order_by('googlecreativespend__spend') for i in queryset: if i.name == 'gs_video1031v1': print(i.name) | gs_video1031v1 | gs_video1031v1 | gs_video1031v1 I.e. by creating 3 googlespend objects I get 3 duplicates for googlecreative after sorting. According to How to sort queryset based on foreign key with no duplicates I tryied queryset.distinct() and queryset.distinct('googlecreativespend__spend') But it doesn't work How to fix it ? -

Django field should not be shown in form but added by middleware at POST request
Let's say I've the following model: from django.db import models class MyModel(models.Model): foo = models.CharField() bar = models.CharField() The field "foo" should not be shown in the create form. Therefore the form is: from django.forms import ModelForm class MyForm(ModelForm): fields = ('bar',) The field is NOT shown in the form. Excellent! Now when POSTing the form, a middleware adds the 'foo' field to the POST vars. But when saving I get an "NOT NULL constraint failed: foo" error. There seems to be some magic code aligning the POST vars (with "foo") to the form fields (w/o "foo"). I already played with the "editable=False" setting, but no success, same behaviour. Any idea how to resolve this? -

How can I add the currently logged in username to the access log of django.server?
I'm trying to add the currently logged in username, if any, to the access log of a Django app: INFO [django.server:161] "GET / HTTP/1.1" 200 116181 ^ username should go here My main problem is how do I share the user/username between the middleware and the filter, since in the filter I don't have access to the request object? I've got a working solution using thread-local for storage, but this doesn't seem like a good idea. Especially since I can't cleanup the value in process_request as it is then cleared too early, before the log line is printed.

Django: matching query does not exist. Error: 500
I'm trying to find a bug - already a second day. The goal was to create a button to save in-session a piece of information about a particular page that would be "read later".

Reusing a database record created by means of Celery task
There is a task which creates database record {R) when it runs for the first time. When task is started second time it should read database record, perform some calculations and call external API. First and second start happens in a loop In case of single start of the task there are no problems, but in the case of loops (at each loop's iteration the new task is created and starts at certain time) there is a problem. In the task queue (for it we use a flower) we have crashed task on every second iteration. If we add, at the and of the loop time.sleep(1) sometimes the tasks work properly, but sometimes - not. How to avoid this problem? We afraid that task for different combination of two users started at the same time also will be crashed. Is there some problem with running tasks in Celery simultaneously? Or something we should consider, tasks are for scheduled payments so they have to work rock solid -
How do I apply higher permissions to child pages in Wagtail?
I am building an intranet site for my organization with Wagtail and we are in the process of adding a knowledge base. The entire site needs to be restricted to logged-in users, but certain pages need to only be accessible to users in certain groups. For instance, only members of the IT group should be able to access the pages underneath the IT Knowledge Base page. Currently if I set the top-level page to be accessible only by logged-in users, that permission is applied to every page on the site, and I am barred from setting more specific permissions on any child page. It is imperative that I be able to set more specific permissions on child pages. I was able to find Wagtail Bug #4277 which seems to indicate that the logic for more specific permissions is implemented but not exposed in the admin UI. I am not familiar with the inner workings of Wagtail yet, especially how Wagtail permissions intersect with Django permissions. How can I add more specific permissions to child pages? -

I also have a simple reverse proxy defined in conf.d/bookmarks.conf to manage all of that: server { listen 80; listen [::]:80; location /api/ { # Backend proxy_pass http://127.0.0.1:1337/api/; } location / { # Frontend root /var/www/bookmarks/html/; index index.html; try_files $uri $uri/ /index.html; } } I run my Django app with runserver python manage.py runserver 127.0.0.1:1337, and React static files are stored in the folder described above I try to connect to API with React: const generateOpendIdLink = async () => { const generateOpendIdLinkEndpoint = 'http://127.0.0.1/api/opendid-link-generator/'; const requestOptions = { method: 'GET', headers: {'Content-Type': 'application/json'}, }; try { const response = await fetch(generateOpendIdLinkEndpoint, requestOptions); if (response.status == 200) { ... }; } catch (error) { console.log(error); }; }; And get an error GET http://127.0.0.1/api/opendid-link-generator/ net::ERR_CONNECTION_REFUSED This is quite odd, because I could connect to API from the web no problem: running the same GET on the server IP address http://XX.XXX.XX.XX/api/opendid-link-generator/ from Postman works as expected. This is also true when I change 127.0.0.1 for the server IP in the React code, it all starts to work. I also set ALLOWED_HOSTS = ['*'] for test … -
