Django sitemap.xml shows plain text
I have added sitemaps following Django 2.0 (I cannot upgrade for now) official documentation. When accessing my production site I get all the correct links with dates but as plaintext, without xml formatting. The google search console is not accepting this format. My sitemap.py code: from blog.models import Post from django.contrib.sitemaps import Sitemap from courses.models import Course, Interview, Lesson class PostSitemap(Sitemap): changefreq = 'weekly' priority = 0.9 def items(self): return Post.objects.all() def lastmod(self, obj): return obj.updated ... My urls.py code: path( "sitemap.xml", sitemap, {"sitemaps": { "courses": CourseSitemap, "posts": PostSitemap, "lessons": LessonSitemap, "podcasts": InterviewSitemap, }}, name="django.contrib.sitemaps.views.sitemap", ), How can I change it to XML format? -

Expose host port 80 of a Dockerized Django app deployed on AWS Fargate
I have a very simple Django rest framework (DRF) app that is dockerized and deployed on AWS ECS with Fargate. I created a security group to expose the port 8000 on the inbound rules and was able to see the app at public IP 12.34.56:78:8000/ I wanted to have the app run on port 80, but don't know how to. Do I need to expose 80 on the Dockerfile and specify that port when creating the task definition? Or do I need to set up nginx to pass HTTP requests to port 8000 internally?

Is there a way to temporarily remove items from a session and re-add after code has run
I am working on an e-commerce site, using Django. I am trying to add a custom order to the bag which is happening, however now I cannot add other products to the bag when the custom order is in the bag.

How to setup cookiecutter-django to run functional tests with Selenium?
I am using Cookiecutter Django with Docker and Webpack. I'm struggling to use Selenium for functional tests with the way Cookiecutter Django template is set up. I have added a Selenium container: selenium_chrome: image: selenium/standalone-chrome:latest container_name: local_selenium_chrome ports: - '4444:4444' volumes: - /dev/shm:/dev/shm I am using Django StaticLiveServerTestCase in my functional test. This is launching a live Django server on a random port, which I can access like this: self.browser.get(self.live_server_url). However, the static files are missing (CSS and JS) because they are served from a node container in the Cookiecutter Django local setup. What is the correct way to update my Cookiecutter Django template to be able to run Selenium tests with full static assets available? -
Djangosaml2 implementation with azure SSO with an existing Django app having independent Login
I am a new comer in Django field. I have an existing Django application with independent login implemented. The task is to integrate Azure AD Single Sign On using SAML protocol. The flow is user request for application url, it will redirect to the Azure portal, Signed in using federated credential automatically and redirect to the requested url or a specific app url after authorize. I am using djangosaml2 librery. I am able to redirect to the Azure portal but while authenticating I am getting "csrf verification failed" error. Basically I have zero knowledge about how django authentication works and how to integrate the response from azure in django.

How to pass AWS ELB health check with Django ALLOWED_HOSTS = [my-site.com]
I have a Django application deployed on AWS via ECS (Dockerized) using gunicorn and nginx. As the DEBUG=False for Django deployment I've configured a logging setting to receive logs on WARNINGs & above via mail_admins. With a standard setup on nginx configuration (below) I started to receive tons of logs (mails) with 'BadRequest' or 'DisallowedHost' errors (most probably scanning/scraping bots) which were rejected by Django as I have set my ALLOWED_HOSTS=[my-site.com]. nginx.conf upstream django-backend { server 172.17.0.1:8000; } server { listen 80; location / { proxy_pass http://django-backend; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_redirect off; } } I followed examples from following solutions to block the traffic hitting my Django application: by @Brent O'Connor from here by @Janusz Skonieczny from here nginx docs here Having ultimately nginx.conf updated with: server { listen 80; server_name ""; return 444; } server { listen 80; server_name my-site.com; # Rest of configuration } This worked quite well, however, I couldn't setup the nginx in such way to allow AWS ELB to perform the Health check and I had following logs in AWS: xxx.xx.xx.xx - - [26/Feb/2024:19:30:03 +0000] "GET /health HTTP/1.1" 444 0 "-" "ELB-HealthChecker/2.0" "-" xxx.xx.xx.xx - - … -
Are there any best practices for handling arbirary rules by US State?
This question is incredibly hard to google because of what state means in software development. I am creating a web app that handles specific laws based on State. These laws often have nothing to do with each other on a State by State bases. For example if it was laws on food sales, one State might say "you can only sell ice cream on Tuesdays" and another might say "every receipt for vegetable sales must be green". Are there any best practices for arbitrary specific rules in a code-base? Obviously, I could throw if statements in for every use case but it will make the code super messy. I am thinking of creating a service class that can point to the State requirements for different from one location but will keep State logic separate from the core shared logic. For reference it is a pretty typical infrastructure with a React-based front-end, Django back-end and mysql DB. -
I'm having trouble verifying my reCAPTCHA

Using Arrays vs Temp Tables for a user session
I am prototyping an event system app for a local organization. They are logging into the site and then API calls use their entered login info to retrieve information from other apps. The goal is to not store any long term "user data" since that is stored in the other apps. (by user data, I mean stuff for logins/settings/etc since its stored in those other apps). The info retrieved from the API calls is displayed to the user but is only needed for the length of the registration process. Once the user registers for the event, the data gotten from the API calls and such should be deleted and the only data saved long term is the data that makes its way to the separate event registration table. Is it better to do a temp table or to store the temporary information in a session variable/array? We are only anticipating maybe 500 concurrent users. -
GeoDjango endpoint is extremely slow
I'm trying to work with a list of 1.100 rows loaded in a PostgreSQL with PostGIS extension. Each row has the following fields: code (integer) name (char) mpoly (multipolygon) The idea is to have an endpoint that will be called from a VueJS app to print each geo data in a Leaflet managed map. The query is extremely slow when serializing it. How can I optimize it? I thought about having a geojson file, but each row has a manytomany table associated that indicate some groups that it belongs to. -

Unable to split text received as POST request in django

I have checked that i am receiving text from html form and the type of text is str. But when i use the same code outside of django such as in jupyter notebook, it work well and split the text.

Save the current user when saving a model in Django admin backend
I'd like to store the user that saved a model for the first time in one of the fields of that model. This is what I have. models.py: from django.conf import settings class Project(models.Model): [...] added_by = models.ForeignKey(settings.AUTH_USER_MODEL, null=True, blank=True, on_delete=models.PROTECT) def save_model(self, request, obj, form, change): if not obj.pk: obj.added_by = request.user super().save_model(request, obj, form, change) settings.py: AUTH_USER_MODEL = 'auth.User' The request.user appear to be always empty (I'm logged in as root to the /admin). What am I missing? -
Django+Nginx having issue with SSE
I made an API on django rest framework, I have SSE via django-eventstream Deployed everything on the server (django in docker), wrote a config for nginx But for some reason the SSE query does not work, everything else works I even added print to the function from the module to check if the request reaches the api, everything is ok But in the postman there is an endless sending of the request, although I checked locally - everything worked Nginx conf location /events/orders/ { proxy_pass http://172.23.0.3:8005/events/orders/; proxy_set_header Host $host; proxy_http_version 1.1; proxy_set_header Connection ""; proxy_buffering off; proxy_set_header Content-Type text/event-stream; proxy_cache off; proxy_buffers 8 32k; proxy_buffer_size 64k; } ASGI os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'sushi_api.settings') application = get_asgi_application() -
Where the actual db fetch is done in drf list()
As you may know the querysets do the actual fetch data only when you evaluate them for ex iterating over them. I want to put that actual fetch inside celery so I need to catch the method in which that actual fetch data from db happens during drf lifecycle. what is it? I'm diving in drf source code but since I have not much time any help is appreciated. -
Social Authentication (dj_rest_auth) with multiple role user
#user_model: class User(AbstractUser, PermissionsMixin): class Role(models.TextChoices): SELLER = "seller" BUYER = "buyer" SUPER = "super" name = models.CharField(max_length=100) phone = models.CharField(max_length=15) email = models.EmailField() created_at = models.DateTimeField(default=timezone.now) shipping_address = models.CharField(max_length=100, blank=True, null=True) role = models.CharField( max_length=100, default=Role.SELLER.value, choices=Role.choices ) updated_at = models.DateTimeField(default=timezone.now, null=True) first_name = None last_name = None profile_picture = models.ImageField( default="profile 1.jpg", upload_to="profile_images" ) is_staff = models.BooleanField(default=False) is_blocked = models.BooleanField(default=False) is_active = models.BooleanField(default=True) is_superuser = models.BooleanField(default=False) username = models.CharField(max_length=30, unique=True) USERNAME_FIELD = "username" REQUIRED_FIELDS = ["email", "name", "role"] objects = myUserManager() class Meta: unique_together = [("email", "role"), ("phone", "role")] ordering = ["id"] db_table = "users" I've implemented dj_rest_auth with Google Authentication, and it functions as intended. However, a limitation arises wherein it only supports users with a single role. For instance, if we create a user with the role of seller, it successfully creates an account and logs in the user. However, if we attempt to log in with a user role such as buyer, it erroneously returns the seller user and logs them in instead. #CustomSocialLoginSerializer: import requests from allauth.socialaccount.models import SocialAccount from dj_rest_auth.registration.serializers import SocialLoginSerializer from django.contrib.auth import get_user_model from django.core.files.base import ContentFile from rest_framework import serializers from rest_framework.response import Response User = get_user_model() class CustomSocialSerializer(SocialLoginSerializer): … -
Django The custom permissions granted in the admin site do not work
I created permissions for the drop-down list, gave the user permissions for the drop-down list on the administration page, so that after logging in he could see only item 1 and item 2.
