Prevent Django DetailView from adding template context with name of object
I have a DetailView for users, and it seems to be adding a user context variable. This is problematic because I have an application-wide context variable, user that contains the current user that is being overridden. How can I prevent the DetailView from adding this context variable? -
Error related to connecting Django from Docker to Nginx
I am currently working on Docker and have done the following: The Django test page was working fine on localhost. I connected it to Docker. I also connected Docker to Gunicorn. However, when I try to connect it through Nginx, only the default Nginx page is displayed, and it is not connecting to the application I created. nginx/Dockerfile FROM nginx:latest RUN rm /etc/nginx/conf.d/default.conf COPY nginx.conf /etc/nginx/conf.d # nginx/nginx.conf upstream daniel_blog { server web:8000; } server { listen 80; server_name localhost; # Default location location / { proxy_pass http://daniel_blog; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $host; proxy_redirect off; } # Static files location /static/ { alias /usr/src/app/_static/; } # Media files location /media/ { alias /usr/src/app/_media/; } } --- # .env.dev DEBUG="1" SECRET_KEY="django-insecure-88ndzs0z0uzko4x5f=*ngu=#h+a(k=!#ooyvt*0h+78r1n=^oy" DJANGO_ALLOWED_HOSTS = localhost 127.0.0.1 [::1] SQL_ENGINE=django.db.backends.postgresql SQL_DATABASE=daniel_blog_dev SQL_USER=daniel_blog_user SQL_PASSWORD=daniel_blog_db_password SQL_HOST=db SQL_PORT=5432 --- # .env.prod DEBUG=0 SECRET_KEY=w4+=--yyyigm1-=na@9et*1ldt-q-x4x=57m2xkiru6!oxeh5b DJANGO_ALLOWED_HOSTS=localhost 127.0.0.1 [::1] SQL_ENGINE=django.db.backends.postgresql SQL_DATABASE=daniel_blog_prod SQL_USER=daniel_blog_user SQL_PASSWORD=daniel_blog_db_password SQL_HOST=db SQL_PORT=5432 --- # .env.prod.db POSTGRES_USER=daniel_blog_user POSTGRES_PASSWORD=daniel_blog_db_password POSTGRES_DB=daniel_blog_prod --- # docker-compose.yml services: nginx: build: ./nginx volumes: - static_volumes:/usr/src/app/_static - media_volumes:/usr/src/app/_media ports: - 80:80 depends_on: - web web: build: . command: gunicorn daniel_blog.wsgi:application --bind 0.0.0.0:8000 volumes: - static_volumes:/usr/src/app/_static - media_volumes:/usr/src/app/_media - ./:/usr/src/app/_media expose: - 8000 env_file: - ./.env.prod depends_on: - db db: image: postgres:17.0-alpine volumes: - postgres_data:/var/lib/postgresql/data/ … -
Sorting a string before a number with Postgres and Django
I want to use fuzzy dates for sorting a Django query, so you can use a full date if you have it, but maybe you only know year and month. For example, Jan XX 2024 would come before Jan 1 2024 and Jan 2 2024. I was originally planning to store as a string 202401XX, 20240101, etc, but Postgres naturally sorts characters after numbers so this would put the date with no day AFTER the date with day specified. I was thinking of converting the 20240101 to letters before saving to the database (X=A, 0=F, 1=G, etc) since this is a computationally cheap thing and I could control where everything sorted. Is this a terrible idea? Is there a better way? I don't want to do a custom Postgres query because that would be complicated with Django's built-in pagination -
Is there way to display historical records for all model instances using django-simple-history?
I am using django-simple-history for saving history of the objects. And it works fine. But I want to create a view in django admin that displays history records for all instances in model in one page. For example I have a model class TestModel(models.Model): title = models.CharField('title', max_length=100) history = HistoricalRecords() and admin class TestModelAdmin(SimpleHistoryAdmin): list_display = ['title'] admin.site.register(TestModel, TestModelAdmin) And now I can see the history of each instance. Not sure how I can solve this problem. May be there is a way to create custom views in admin site (without model), or maybe I should create another model? What's the best way to display all history records (for all instances) in admin panel? -
Redirecting from DELETE to GET in Django
I use Django django 4.0.8 and django-tastypie. Why is it that when I send a request (for example) http://127.0.0.1:8000/api/v1/courses/3 via Postman, I get a redirect to GET /api/v1/courses/3/? If I send http://127.0.0.1:8000/api/v1/courses/3/ it work correctly. Adding 'APPEND_SLASH = True' in settings.py does not resolve this problem. String "MIDDLEWARE = ['django.middleware.common.CommonMiddleware']" I have in settings.p -
How to handle user login through Spotify (what to do with tokens)
I'm trying to create a web app using a Django backend and React frontend. This is my first time using Django and dealing with accounts specifically. The app revolves around Spotify accounts so to login a user has to login through Spotify. I understand the authorization process and can get a user's access/refresh token, but I'm not sure what to do from here. I have found a lot of conflicting information online. Most people say not to use local storage which makes sense. Right now I am trying to implement it using Django sessions, but I've read online about that not scaling well/not being RESTful so I'm confused. I also looked at using django-allauth and it worked, but I'm confused with how it would work with my React frontend because as far as I understand it, it's just something I can do only in Django (localhost:8000). I want to be able to create a User in my database once a user logs in for the first time. From here, do I store the user's tokens inside the database too? Do I use Django's User model at all? I saw people mentioning Django's built-in authorization but confused how that ties in … -

Authentication with Django Ninja, allauth or other solid solution?
I'm creating an API with django ninja, and I wanted to implement user authentication and accounts. I like allauth for it's social account functionality built in, as I plan for users to be able to link steam/xbox accounts and I've seen you can use this with drf relatively easily? Can I implement it with django ninja, or is there any other good authentication for ninja specifically. Also, will I need token authentication for this if at some point in the future it may interface with a mobile application? Thanks for the support. -
How to alter data entered into django models to fit a criteria?
I have a django models.py file that I use to store information in my database. I store information on businesses and the countries that they operate in. I get the list of countries from their website. However they may call each country by a different name or use different formatting, for example 'The Gambia' vs 'Gambia', 'Eswatini' vs 'Swaziland', 'Trinidad and Tobago' vs 'Trinidad & Tobago'', 'The United States' vs 'United States of America'. I want that when I store the names of these countries in my database they automatically follow a set of rules to ensure consistent formatting of their names. Additionally, some websites state something like 'We operate in 150 countries'. I want to enter this information into the database but not have it come up when I request a list of countries from the frontend. Here is my models.py: class Company(models.Model): #the newly created database model and below are the fields name = models.CharField(max_length=250, blank=True, null=True) #textField used for larger strings, CharField, smaller slug = models.SlugField(max_length=250, blank=True, db_index=True, unique=True) available_merchant_countries = models.TextField(max_length=2500, blank=True, null=True) available_merchant_countries_source = models.URLField(max_length=250, blank=True, null=True) -

Datatables instance not synced with DOM (input checkbox status)

Django view to PNG
I'm writing django webapp, and part of it is to generate view and convert it to png image. (any ideas other then below are appreciated). I've looked at some tools to convert "html to png", but there is mainly problem with {%static files and templates. Another approach is to render page using django templates in browser, and take screenshot. It can be done using "chromedriver" + selenium. I was able to do it in my local ubuntu. But on production - all I've got is remote (ssh) access to some linux bash, where my application is hosted. I've created venv, pip-installed selenium and (chromedriver-py or chromedriver-binary). For the second one - it looks like it is closer to start working, but I've got error message: SessionNotCreatedException Message: session not created: probably user data directory is already in use, please specify a unique value for --user-data-dir argument, or don't use --user-data-dir Stackoverflow says, that I should somehow put there a path to my chrome installation's user dir, but is there any chrome installation in that console bash of mine?

How to make Django's Browsable API Renderer generate correct URLs with an /api/ prefix when behind Nginx?
I'm deploying a Django application using the Django Rest Framework (DRF) on a server behind Nginx. The application is accessible via https://my-site.com/api/ where /api is routed to the Django application. However, when I access the API's browsable UI at https://my-site.com/api/locations, everything works fine. But when I try to click the "Get JSON" button from the UI, it generates an incorrect URL: /locations?format=json instead of the correct /api/locations?format=json. Or when i try to POST it posts to /locations instead of /api/locations The issue is that the DRF Browsable API Renderer seems to be constructing the URLs as if the app is running directly under the root path (/), but in reality, it's running under /api/ on the server due to Nginx routing. # Proxy requests to the Django backend (API) location /api/ { proxy_pass http://127.0.0.1:8000/; proxy_set_header X-Script-Name /api; # Tell Django it's running under /api 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; } What I'm Looking For: A solution to make the Django Browsable API Renderer correctly generate URLs with the /api/ prefix when behind Nginx. -
