Django Channels Config - Django / Docker / Gunicorn / Daphne / Nginx
I have deployed an app, pypilot.app using django / nginx / docker / daphne / gunicorn on a digital ocean droplet. Daphne is for Django Channels which works no problem in development to display messages in a user's console via websocket. I'm also able to connect to the websocket successfully when navigating to my droplet's IP address over http. When I try to connect to websocket via https at pypilot.app, however, I run into issues. I suspect something is wrong with my ssl setup perhaps? Please let me know if you spot any obvious issues in my setup below. docker compose version: '3' services: web: build: . command: gunicorn unicorn_python.wsgi:application --bind 0.0.0.0:8000 volumes: - .:/code - .:/usr/src/app - /var/run/docker.sock:/var/run/docker.sock ports: - "8000:8000" daphne: build: . volumes: - .:/usr/src/app - .:/code ports: - "8001:8001" command: daphne -b 0.0.0.0 -p 8001 unicorn_python.asgi:application nginx: image: nginx:latest ports: - "80:80" - "443:443" volumes: - ./config/nginx:/etc/nginx/conf.d - /etc/letsencrypt:/etc/letsencrypt:ro - ./static:/usr/src/app/static # Host path to static files mounted inside the container - ./media:/usr/src/app/media # Host path to static files mounted inside the container depends_on: - web - daphne # If Nginx is set to proxy to Daphne as well celery: build: . command: celery -A unicorn_python … -
Django request.user isn't using the custom backend at all
I'm coding with a custom user model and a custom backend in Django 5.0 to login with an email. Here is the backend : class EmailBackend(ModelBackend): def authenticate(self, request, username=None, password=None, **kwargs): print("authenticate called") try: user = User.objects.get(email=username) except User.DoesNotExist: return None else: if user.check_password(password): return user return None def get_user(self, user_id): try: print(user_id) print("get_user called") return User.objects.get(pk=user_id) except User.DoesNotExist: return None It's correctly registered in AUTHENTICATION_BACKENDS, and the user model just have an email field. The backend works perfectly in my register view using authenticate(request, username=email, password=password), and the login(request, user) works too. However, if in another view, after a login I try to use request.user, it will always return AnonymousUser. If I do request.session.values, the user ID is correct. I can't find anyone having the same issue online, so I hope someone can help me troubleshoot it. I tried to use request.user with the custom backend, but it's never called. I also tried to use request.session.values and this time the user ID was correct. The request.user was supposed to return the current user with my custom model, but it always return AnonymousUser -
Detect if a Django related object has been prefetched via select_related
Let's say I have the following models: class Product: name = models.CharField(max_length=128) class ProductVersion: name = models.CharField(max_length=128) product = models.ForeignKey(Product, on_delete=models.CASCADE) For a given ProductVersion object, is there anyway to detect if the Product object was prefetched via select_related? For example: # Yes, "product" was prefetched ProductVersion.objects.select_related("product").first() # No, "product" was NOT prefetched ProductVersion.objects.first() Looks like there's a way to do this was prefetch_related (see here) but I need it for selected_related. -
Django / Celery : How a task can constantly do something ? Is it possible to set an infinite loop for a task?
I'm currently learning Django and Celery. So I have to do a feature to a Django projet, and I use Celery for that : I need to constantly check a list in my Redis server. And for that, I use Celery but I don't know how I can implement correctly that and I opted for a while True:. After the launching of my task with celery -A <my_project> worker -l INFO, it's impossible to kill the task (the CTRL + C doesn't work), or I don't found how I can. I conclude it's not a good method for doing what I want. One more thing : I know the extension django-celery-beat exists but I think it's "weird" to open another terminal for launch this extension. Already I have to launch my django server, then my worker (with celery) on two different terminals, I have to open a third to launch my scheduled task, I don't know if this is really weird to do that, but... I don't know, I think it's weird to do that but I don't know if it really is. Here's my (unique) task in an app in my django project : from celery import shared_task import … -
Rewrite User logic in Django
I need to completely rewrite the user logic in Django. I would like to store only 2 parameters in the database: phone number and telegram_id. The user could login and register with both of these parameters from one page. So I need to rewrite the model and write custom views and urls. The main question is how do I write a user model from scratch, replacing the standard django one. However, I wouldn't want to completely remove the user block and write it from scratch. Just models and some views and urls Search the internet. -

OpenAI API Integration in Django: Request Getting Lost on Server
I have integrated the OpenAI API into my Django project for generating dynamic descriptions for tables generated in my application. The workflow involves processing user input, generating tables, and then passing these tables to the OpenAI API one by one using client.chat.completions.create. While this works smoothly on my local system, when deployed on the server, the request sometimes seems to get lost at the point of calling client.chat.completions.create. It returns the response processed until that stage, rather than waiting for the completion response from the OpenAI API. try: chat_completion = client.chat.completions.create( messages=[ {"role": "system", "content": "You are a helpful assistant."}, {"role": "user", "content": prompt}, ], model="gpt-3.5-turbo", temperature=0.5, max_tokens=1024 ) logger.info('---- GPT4') logger.info("chat completion",chat_completion.choices[0].message.content) response_content = chat_completion.choices[0].message.content logger.info('---- GPT5') except Exception as e: logger.info('---- Error in chat gpt "',str(e)) pass Upon debugging, it seems that the request doesn't wait for the response from client.chat.completions.create, causing it to return incomplete responses on the server. What could be causing this behavior, and how can I ensure that the request waits for the completion response from the OpenAI API before proceeding further? Any insights or suggestions would be greatly appreciated. Thank you! -

How not to save data from Inline Django Model?
I'm trying to implement the ability to view users' locations in a task through the inline Geoposition model. Geoposition stores latitude and longitude, then thanks to changing the tabular.html template I display the map When I try to save the model, I get an error: The number of GET/POST parameters exceeded settings.DATA_UPLOAD_MAX_NUMBER_FIELDS, because data from this Geoposition inline trying to POST. I would not like to change this setting. In this case, the inline model class looks like this class TaskTransitInline(admin.TabularInline): template = "admin/gis/tabular_override.html" model = Geoposition extra = 0 max_num = 0 can_delete = False fields = ( "id", "task", "created_at", "longitude", "latitude", "speed", ) readonly_fields = ["id", "task", "created_at", "longitude", "latitude", "speed"] Why do I then see ID and task in the data POST? Maybe someone can help me -

Django QuerySet: how to aggregate repeated elements and add quantity field to it?

django constraint in multi-tenant application

Dynamically load content from SSR into vanilla JS
I have a project based on Django, which provides different pages rendered by django itself. I want to make this a single page application, so django only serves an index with a full HTML page, and then I use other endpoints for rendering the body, and I inject the content into the index page using JavaScript. This is the index page: {% load static %} <html lang="en"> <head> <meta charset="UTF-8"> <title>Home</title> <script type="module" src={% static "js/index.js" %}></script> </head> <body> <div id="root"></div> <!-- index.js has a function that overwrites the contents of this element with the retrieved page --> </body> </html> And an example of a page: {% load static %} <script type="module" src={% static "js/page.js" %}></scrip> <button onclick="helloworld()"> Click me! </button> The page.js file would have functions like this: function helloworld() { alert("Hello world!"); } This works well enough for loading HTML and CSS content, but not so much for anything related to JavaScript. Using this method, any JS that comes in the SSR response won't be loaded, and the injected HTML won't be able to access any of the JS functions loaded along with the index page unless I assign them to a global object like window or document. … -

Webapp in pure Pyton resp. without JS?
I search a Language and / or Framework to develop a professional Webapp in (for example) pure Python. My prefered language is python, but i could also use somethin other. The point is, that I don't want to use JavaScript, because i probably hate that shit. (sorry for that statement). I was flirting with Django and recently read about Reflex. But I'm not sure if I can develop a really stunning frontend with Django (without a JS framework) and Reflex perhaps seems to be a bit immature (I'm not sure about this...). So the goal is to develop a whole Webapp (but more or less small and simple) without using JS, and ideally with python. Since i perhaps wanna do some numerical calculations or data science stuff in the backend / background, i think python would be easy and straight forward. Constraints: I don't want to use the Microsoft dotnet stuff. It's important, that i can use nearly any database in the background. Perhaps I wanna use a Graph-Database at the end. But i'ts open now. (... open arch, freedom to choose...) Optional: I could also use some other langauge? (sic!) It should be fully OpenSource to use, perhaps with … -
Unable to create UserProfile object for User
I have a User model and a UserProfile model with a one-to-one relationship. I'm using a serializer to create users, and I want to automatically create a corresponding UserProfile object for each user upon creation. However, I'm encountering an issue where the UserProfile object is not getting created when I create a new user. Despite setting up the UserProfile model with a OneToOneField relationship to the User model and specifying the related name as "userprofile", I keep getting an error stating that there is no related object. Additionally, when I retrieve user data using the GET method with this serializer, the userprofile field shows as null, even though I expect it to contain the related UserProfile object.

Issue with Django CMS Icon Module: Missing Static Path and Extra Class in Generated Markup
I am attempting to utilize the djangocms-icon module to incorporate my own SVG icons into my Django CMS project. Following the documentation, I have successfully added Material Design icons. However, I encounter issues when adding my custom SVG icons. In my settings.py, I added the following code: with open('iconset.json') as fh: ICONSET = fh.read() DJANGOCMS_ICON_SETS = [ ('fontawesome5regular', 'far', 'Font Awesome 5 Regular', 'latest'), ('fontawesome5solid', 'fas', 'Font Awesome 5 Solid', 'latest'), ('fontawesome5brands', 'fab', 'Font Awesome 5 Brands', 'latest'), ('materialdesign', 'zmdi', 'Material Design'), (ICONSET, 'svg-icon', 'My Icons'), ] DJANGOCMS_ICON_TEMPLATES = [ ('svg', 'SVG template'), ] I have created an iconset.json file at the root of my project: { "svg": true, "spritePath": "sprites/icons.svg", "iconClass": "svg-icon", "iconClassFix": "svg-icon-", "icons": [ "svg-icon-card", "svg-icon-card-add" ] } I have also created my icons.svg file in static/sprites/icons.svg: <svg width="0" height="0" class="hidden"> <symbol xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" id="svg-icon-card"> <!-- path data --> </symbol> <symbol xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" id="svg-icon-card-add"> <!-- path data --> </symbol> </svg> Additionally, I created templates/djangocms_icon/svg/icon.html: {% load cms_tags static %} <span class="icon {{ instance.attributes.class }}"> <svg role="presentation"> <use xlink:href="{% static 'sprites/icons.svg' %}#{{ instance.icon }}"></use> </svg> </span> The issue arises in the generated markup.

How to send confirmation emails and scheduled emails in Django
I'm working on a Django project involving a custom user registration form. My goal is to implement a two-step email notification process upon form submission: Immediate Email Confirmation: Automatically send a customized email to the user immediately after they submit the form. Scheduled Email Notification: Send a second customized email at a later date, which is determined by the information provided when the form is created (e.g., a specific date for event reminders). The scheduling of the second email needs to be dynamic, allowing for different dates based on the form's context, such as varying event dates. How can I achieve this with Django? especially for scheduling emails to be dispatched at a future date. Note that I expect a volume of 1000 submissions per month. Thanks for your help in advance.
