How to make a table only visible to a specific user in Django
So, I was studying Django and started doing some projects to fixate what I learned. I'm building a contact book like website and want to make each user have a unique Contacts table. I've tried putting this on models.py: class UserContatos(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) class Contato(models.Model): nome = models.CharField(max_length=255) sobrenome = models.CharField(max_length=255, blank=True) telefone = models.CharField(max_length=255) email = models.CharField(max_length=255, blank=True) data_criacao = models.DateTimeField( default=timezone.now) descricao = models.TextField(blank=True) categoria = models.ForeignKey(Categoria, on_delete=models.DO_NOTHING) mostrar = models.BooleanField(default=True) foto = models.ImageField(blank=True, upload_to='fotos/%y/%m/%d') def __str__(self): return self.nome contatos = Contato() class ContatoForm(forms.ModelForm): class Meta: model = UserContatos.Contato exclude = ('',) When I use this form to create a contact, it doesn't "go to the user". -
Export MUI components or style to use outside of React app
I'm facing a use case I'm not familiar with. I'm currently using MUI for a React application, but the authentication part is handled on another server, a Django application that includes Django OIDC Provider lib and which mostly consists in a sign in form that redirects the user to the React client upon sign in. The ultimate goal would be to have the same look and feel across both applications to provide a better user experience, I'm wondering what is the best solution for this: embed a full React application into the Django project and share the MUI theme across both application, seems to be the best choice for consistency but will be costly in term of development time and bundle size of the authentication app (basically loading React + MUI just for one page) trying to mimic the MUI components (mostly text fields, checkbox, buttons) with a pure CSS solution like https://github.com/finnhvman/matter which looks very nice, but it will take time to reproduce the main React app MUI theme, it will be harder to maintain and it will be hard to provide the exact same interactivity somehow find a way to export pure CSS with MUI theme style or … -
Django - Storing total API request from user, Limit and Filter it [Django Ninja]
I'm new to django, i'm currently working with API using Django Ninja Rest Framework. in this example, users will have a unique APIKey each time i create new APIKey from this model and attach it to selected user. this is my APIKey model : ### NOTE - This is just for testing, Not a real model, see the link below class APIKey(models.Model): key = models.CharField(max_length=64) # i know this should be unique, just for demo :) user = models.ForeignKey(get_user_model(), related_name='free_key', on_delete=models.CASCADE) label = models.CharField(max_length=40) revoked = models.BooleanField(default=False) created_at = models.DateTimeField(auto_now_add=True) expires_at = models.DateTimeField(null=True, blank=True) This model is just for testing purposes, I actually use this for my project and modify it. So, My API endpoints need an API key for authentication (the API key that i have created that correspond to a specific user), so i implement and follow the steps here and it works normally My questions are : Each user has a unique API key. How to count and store the total request from a user each time user makes a request to an endpoint ? Should i add request_total field to my APIKey model or create a new Model ? Should i use custom middleware? or should … -
Django + nginx (with docker): erratic /admin redirects
So, I have a project that features a Docker deployment of a website with Nginx, Django served with Gunicorn + static files, and a Vue.js frontend (compiles to static files). The problem: When I try to access Django's admin interface, at http://localhost:8100/admin, I am redirected to https://localhost/admin/, which obviously fails. What I really want: First, for this to work. But I don't want to hardcode a website name (because it's an open source project), I don't want to force SSL, because I have a server where I'm going to deploy this behind another reverse proxy so that the website will be some subdomain on my server, under my certificates. So I want for both the Nginx and the Django layer to be as "dumb" as possible. To help debugging: docker-compose.yaml: version: "3" services: reverse-proxy: image: nginx:stable ports: - 8100:80 volumes: - frontend_data:/frontend/ - backend_data:/backend/ - ./nginx:/etc/nginx/conf.d depends_on: - backend frontend: # .... backend: build: context: ./backend dockerfile: Dockerfile entrypoint: ./entrypoint.sh stop_signal: SIGINT depends_on: - db volumes: - backend_data:/backend/ db: image: postgres:13-bullseye volumes: - postgres_data:/var/lib/postgresql/data/ volumes: # ...

Where does a Django generic view class call the database?
I can inherit from a class based generic view from generic.ListView as in class BookListView(generic.ListView): model = Book Supposedly the .as_view() function gets called when the Django app starts up to create an instance of this view. I find the definition of get_queryset in MultipleObjectMixin but what I dont find is, from where is this method called from? -

How to use inputs to do calculations with mathfilters in Django?
I am using mathfilters in Django, I want to do a multiplication between quantity and unit_price and reflect it in total_price. I already followed the documentation from here mathfilters and when implementing it as it says and filling those 2 inputs with numbers, the result is not reflected anywhere Maybe I am not implementing it well but when I search I see that there is very little information to use mathfilters <td> {{presupuestosparteform.quantity}} </td> <td> {{presupuestosparteform.unit_price}} </td> <td> <li>{{ presupuestosparteform.quantity|mul:presupuestosparteform.unit_price }}</li> </td> -

implementing oauth2 for google calendar api with django
Can anybody direct me to a complete example of implementing oauth2 with django? From the older posts, I found some bits and pieces, or work-arounds, but I am not yet experienced enough to put the pieces together. I want to integrate into an web app creating, updating, deleting events. Followed the quickstart in the documentation, it works fine. I need to switch to a web app flow, instead of the installed app flow, here I got stuck, on authorizing the app and on receiving the approval of the resource owners to access their calendars.

How can I get Django inside a docker compose network to recognize the postgres service name while using PyCharm?
I've been fiddling with my Dockerfile and Docker Compose to try and get PyCharm to be able to run and debug my django application. I've identified that I need all services to be on the same network, and have put them on the same network, but when I go to execute the runserver command through my PyCharm configuration, I get an error that django.db.utils.OperationalError: could not translate host name "postgres" to address: Name or service not known I've tried adjusting the Dockerfile to expose environment variables inside of it, instead of in the compose file. As well as grouping all the services into the same network. I'm at a bit of a loss as to where to go from here, as most other StackOverflow questions relating to this tell me to do things I've already tried. docker-compose.yml version: "2" services: redis: image: redis:latest # redis restart: always logging: driver: "none" networks: - integration postgres: image: postgres:latest restart: always ports: - "5400:5399" volumes: - /usr/lib/postgresql - ./tmp:/dmp:ro - ./load.sh:/usr/app/load.sh environment: POSTGRES_USER: vagrant POSTGRES_PASSWORD: vagrant POSTGRES_HOST_AUTH_METHOD: trust logging: driver: none networks: - integration django: build: . command: "/bin/bash" working_dir: /usr/app/ stdin_open: true tty: true volumes: - ./tmp:/tmp - ./:/usr/app - ~/.ssh:/root/.ssh:ro links: … -
Is there a way in Django to expose only a certain range of URLs based on some predefined variable?
I am basically trying to expose a a range of defined URLs in an application. E.g., I have 10k x2 resources which I'm hosting at /metadata/type1_1 and /metadata/type2_1 where each resource grouping iterates up to type1_10000 and type2_10000 respectively (20,000 stored assets I intend to serve over a manually-driven interval). As such, I'm trying to define a URL scheme such that max_available_metadata = current_limit [e.g. this may be 300, 7777 etc.] and I only want to configure the URLs within the pattern up to this limit. e.g., if I sent it to 25, type1_1, type1_2...25 and likewise type2_1, type2_2... type2_25 would all map properly but attempting to go to metadata/type1_26 through type1_10000 would all return 404s, likewise for type 2. I'll probably want to configure setting this via the django admin but this isn't part of the question. -
