Django Project on Azure, 502 error after deployment
I'm deploying a Django app on Azure Web App using Gunicorn and keep getting a 502 Bad Gateway error. Despite binding to the correct port, setting up environment variables for Key Vault, and enabling SCM_DO_BUILD_DURING_DEPLOYMENT for Oryx builds, the site never fully starts. I need to figure out why Gunicorn won't serve the app properly, even though the deployment logs seem fine. I set SCM_DO_BUILD_DURING_DEPLOYMENT=true, placed my requirements.txt in the project root so Oryx could install dependencies, and updated my startup command to gunicorn --bind=0.0.0.0:$PORT. I also configured environment variables for Key Vault, and tested collecting static files locally vs. on Azure. I expected the Azure Web App to run Gunicorn without errors. Instead, I keep getting a 502 Bad Gateway, and my logs show no direct failure message—just that the service never properly responds. -
When and where i use create_user from CreateUserManager()?
For several days now, I've been wondering why I should create my own user manager in Django, since in the end, when inheriting a built-in form, I don't refer to my created manager anyway. class CustomUserManager(BaseUserManager): def create_user(self, email, birth_date, password=None, **extra_fields): if not email: raise ValueError("You didn't entered a valid email address!") email = self.normalize_email(email) user = self.model(email=email, **extra_fields) user.set_password(password) user.save(using=self._db) return user def create_superuser(self, email, password, **extra_fields): extra_fields.setdefault('is_stuff', True) extra_fields.setdefault('is_superuser', True) return self.create_user(email, password, **extra_fields) I have something like this and in the end when it creates a user it doesn't go through that create_user anyway. So my two questions: Why create something for a custom user if I don't end up using it anyway because the form inherits from UserCreationForm. So, for example, form.save() does not use my manager. At what point should this create_user be executed? -
asynchronously database routing in djago and celery
I am implementing subdomain-based database routing, and it is working fine. However, when a task is executed asynchronously, the database that has been dynamically routed gets overwritten by the default one. How to handle that in Django? # middleware.py from django.db import connections from django.conf import settings from django.http import HttpResponse class SubdomainDatabaseMiddleware: def __init__(self, get_response): self.get_response = get_response def __call__(self, request): # Get subdomain from the request subdomain = request.META.get('HTTP_HOST', '').split('.')[0] subdomain = 'tenant' # Set the database connection based on subdomain if subdomain: request.subdomain = subdomain self.set_database(subdomain) else: request.subdomain = None response = self.get_response(request) return response def set_database(self, subdomain): # Dynamically set database for the subdomain database_alias = f'{subdomain}' if database_alias in settings.DATABASES: connections['default'] = connections[database_alias] else: # Default behavior if no database configured for subdomain pass -
Django "No installed app with label 'logs'" Error Even After Correcting Project Structure
I'm encountering a persistent "No installed app with label 'logs'" error in my Django project, even after seemingly correcting the project structure and INSTALLED_APPS. I've tried all the common solutions, but the issue remains. Python Version: 3.13.2 Django Version: 5.1.6 os: Windows 11 Project Structure router_log_project/ manage.py router_log_project/ (Inner project directory) __init__.py settings.py urls.py wsgi.py logs/ __init__.py models.py views.py migrations/ __init__.py env/ db.sqlite3 settings.py INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'logs', ] Steps already taken Double-checked INSTALLED_APPS: I've meticulously verified the spelling of 'logs' in INSTALLED_APPS. Verified __init__.py files: I've confirmed that __init__.py files exist in both the inner router_log_project directory and the logs app directory. Restarted the development server: I've restarted the server multiple times after making changes. Deactivated/reactivated the virtual environment: I've tried creating a fresh virtual environment. -
Where the source code files are stored by azure in case of a web app on linux for a python website?
I've created a web app on azure for a python web app. I've successfully deployed it using zip and an azure cli command. It worked and my website works now. But what's really confusing to me is that I don't see my website files via filezilla. I mean it should contain all those scripts and the database file. I'm using sqlite db there. So if I just want to upload some image manually or download a database for a backup or local work with up to date PROD database, how do I do that? The only thing that I've found there is a output.tar.gz file, which contains output.tar file, which contains all of my website files and the database file as well. But would azure server hold all the files that a website is currently using in an archive? It would slow down an app, so I don't believe that those files are up to date with actual working PROD website instance. So how can I download the database file from PROD to my local? -
django reconnect to DB when connection is lost

When deployed to the server (in production), the Gemini API server's streaming responses are not received
It works fine locally. In the production environment, non-streaming responses work well. When I send a Gemini API request directly from the AWS server using curl, the streaming works perfectly. However, when I run the backend server with Gunicorn, the Gemini API streaming does not work. I tried using both gevent and eventlet for the worker class, but neither worked. It doesn't seem to be an issue with the nginx configuration, since streaming responses to the client are sent correctly. The problem only occurs when the server calls the outer API. Actually, everything worked fine when I first set up the server. But ever since I set up the CI/CD pipeline, (I just tried to use github actions and install requirements remote) external API streaming doesn't work. Since it's a Django codebase, even deleting the virtual environment and reinstalling, or installing using the requirements.txt from before the CI/CD build (when it was working fine), doesn't resolve the issue. What should I do? What I got from gunicorn logs [2025-02-14 14:29:50 +0000] [5235] [CRITICAL] WORKER TIMEOUT (pid:5283) Feb 14 14:29:50 ip-172-31-13-205 gunicorn[5283]: response: Feb 14 14:29:50 ip-172-31-13-205 gunicorn[5283]: GenerateContentResponse( Feb 14 14:29:50 ip-172-31-13-205 gunicorn[5283]: done=False, Feb 14 14:29:50 ip-172-31-13-205 gunicorn[5283]: iterator=<_StreamingResponseIterator>, … -
Django-admin makemessages does not detect ngettext strings from .html files (but it detects gettext strings)
Django-admin makemessages does not detect ngettext strings from .html files (write in jinja2), but it is able to detect them in .py files. However, the same command normally detects gettext strings everywhere (including in .html files). I tried django-admin makemessages -l en --ignore="*/site-packages/*" --ignore="*/django/*" and my code in .html is {{ ngettext( '%(num)d lesson', '%(num)d lessons', 3) | format(num=3) }} -

How do I save a Historical field on a non-historical model in Django Simple History?
I have something like a ContractTemplate shared for all clients which is 'versioned' through django-simple-history.

Django - multiple models in one view
I have scoured the StackOverflow pages and none of the solutions to this problem are working for me. I have two models in the same app and am trying to display data from both models in the same template using class based DetailView. This is my code, but the only thing that displays is the data from the Project model. models.py from django.db import models class Project(models.Model): project_name = models.CharField(max_length=100) project_location = models.CharField(max_length=100) def __str__(self): return self.project_name class Well(models.Model): project_name = models.ForeignKey(Project, on_delete=models.CASCADE) well_name = models.CharField(max_length=100) def __str__(self): return self.well_name views.py class ProjectDetailView(DetailView): model = Project template_name = 'project/project_detail.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['projects'] = Project.objects.all() context['wells'] = Well.objects.all() return context html {{ project.project_name}} {{ well.well_name}} What am I missing? The Django docs for TemplateView only show how to display data from one model, not two. -
How Can I Get Django Global Notifications Via Channels To Work?

exclude specific urls from nginx redirect
I'm trying to exclude two URLs from nginx redirect (http to https). Traffic from Nginx is sent to guincorn and the URLs are generated dynamically by the Django view. My current base nginx configuration for the site is below. All non http requests are sent to https using this. server { listen 80; listen [::]:80 default_server; server_name mydomain.org; return 301 https://$server_name$request_uri; } server { listen 443 ssl default_server; listen [::]:443 ssl default_server; ssl_certificate ....; ssl_certificate_key ....; root /app/ioc; server_name mydomain.org; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { alias /path/static/; } location / { proxy_pass http://unix:/run/gunicorn.sock; proxy_set_header Host $http_host; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header X-Forwarded-For $remote_addr; proxy_redirect off; } } Now, I'm trying to exclude both this/endpoint1.txt and this/endpoint2.txt from the redirects. endpoint1.txt and endpoint1.txt are dynamically generated by the django view so they are not actual text files on the server. Trying to do something like this results in 404 error location /this/endpoint1.txt { root /path/app; add_header Content-Type text/plain; } Also, when I do something like this: location /this/endpoint1.txt { proxy_pass http://127.0.0.1:80; } I get 504 Gateway Time-out error.

Best way to implement date with optional day/month?
There are several ways to do this, each with their own advantages and disadvantages. Boolean fields for day/month: Advantages: cheap ordering, easy formatting, easy validation Disadvantages: have to provide a default month/day, ordering may not behave as expected depending on needs date = models.DateField() date_has_month = models.BooleanField() date_has_day = models.BooleanField() Separate IntegerFields Advantages: relatively cheap ordering, flexible ordering with not_null option etc Disadvantages: complicates date validation, must order on several fields, must compose date from several fields date_year = models.IntegerField() date_month = models.IntegerField() date_day = models.IntegerField() CharField Advantages: no need for extra fields, 1:1 with user input (depending on validation) Disadvantages: relatively expensive ordering, ordering is inflexible, validation may be complicated date = models.CharField() My question is: are there more (dis)advantages not listed? Are there other ways to achieve this that I haven't thought of? -

Django can't load static files, even with correct settings
Today i faced a problem with static files. I was adding JavaScript and CSS to my project, but the app could not load it. It did find the files, but could not load them, because the app shows 404 code (see picture). I made sure that i have these lines in my settings.py: STATIC_URL = 'static/' STATIC_ROOT = BASE_DIR / 'static' Then i made sure i ran collectstatic command and linked them in html template. <link rel="stylesheet" href="{% static 'css/style.css' %}"> <script src="{% static 'js/script.js' %}"></script> Anyway, i got 404 in console section of browser Google Chrome Console This is the second time i'm facing this problem. On my previous little project as wel, I encountered the same problem. I tried to find solution to this problem from every corner of internet: this site, django forum and other forums. But i could not find any solution. I have a thought that this problem may be with my laptop or OS maybe. My OS is Linux Ubuntu 22.04 LTS. If there is someone that encountered same problem or has any idea how to solve this problem, I would be glad. -

A problem occurs when adding a new foreign key field to a model
So, I added a foreign key field to my model, ran "makemigrations" and "migrate" without problems, but when I check my database via DB browser, I cannot find that field! This is my model class Listing (models.Model): CATEGORY_CHOICES = [ ("chemistry", "Chemistry"), ("physics", "Physics"), ("math", "Math"), ("litreture", "Litreture"), ("history", "History"), ("language", "Language"), ("sports", "Sports") ] title = models.CharField(max_length=80) brief = models.CharField(max_length=128) description = models.TextField() intial_price = models.IntegerField() category = models.CharField(max_length=24, choices=CATEGORY_CHOICES) # The problem is within the line below creator = models.ForeignKey(User, on_delete=models.CASCADE, related_name='listings') # I cannot find this field in my database file when browsing it via DB browser def __str__(self): return self.title I tried to ask the AI a lot but all it said was to check the migrations files and make sure the migration process is successful. I am sure that there is no issue with those two. I ran out of ideas, help! -
Best place to initialize a variable from a postgres database table after django project startup
I have a django project where I have some database tables. One of the database tables is designed to store messages and their titles. This helps me to create/alter these messages from my django-admin. Now I want to initialize a variable (as a dictionary) from this table as follows : MY_MSGS = {record.name : {'title':record.title, 'message':record.message} for record in MyTable.objects.all()} This must happen at the server startup for now. MY_MSGS must be accessible to the different view-files. FYI I have multiple view-files that are all imported from views.py
