Django frontend convenient handle different responses
I am unsure how to deal with different return options in Django. Let me describe a fictive scenario: I have an endpoint /books/5/ that returns an html showing infos about the book and the chapters it contains. Those are reachable at /books/5/chapters/ and /books/5/chapters/3/ for example. I can make a POST to /book/5/chapters/ via a form with title etc. to create a new chapter. This can either succeed and a new chapter is created or it can fail, because of whatever reason. To make my frontend a bit convenient I included the form to create chapters at the endpoint /book/5/. So I can see the books details and chapters and enter details for new chapter in this view in the form and click create. My desired experience would be that I get a refresh of the /book/5/ to see the new state. If the post failed I would like to see a notification with the error message. Is there a standard way how to do this? I have played around with JsonResponse and returning the next URL to go to and calling the endpoint with a JavaScript function that sets the current window to it. Vut I don't know how … -
post_save seams has bug
my simplified problem is below: i have a model like this: class Alert(models.Model): ALERT_CHOICES = [("email","email"),("sms","sms"),("notif","notif")] name = models.CharField(max_length = 50) owner = models.ForeignKey(User , on_delete=models.CASCADE) coins = models.ManyToManyField(Coin,blank=True) when an object of Alert like alert changes. i want to print number of coins that connected to alert after change in this method: @receiver(post_save, sender=Alert) def handle_alert_save(sender, instance, **kwargs): coins = instance.coins.all() print(len(coins)) Unfortunately! it prints number of coin before change alert. i want after change the object. in other words post_save signal is exactly equal to pre_save. for example when i have 2 connected coin to aler and i change it to 5. it prints 2! i try all other signals like pre_save and pre_delete and pre_migrate and post_migrate. -

Celery does not see objects in SQLite (in Docker)
I have project on Django, DRF, SQLite, RabbitMQ and Celery. When I run the project locally (separately rabbitmq, celery and django), everything works correctly. But when I run it in Docker, the task in celery does not find an object in the database. Attempts to find the created task from the celery container shell are also unsuccessful (I only see old objects). If I enable CELERY_TASK_ALWAYS_EAGER=True setting, then everything works fine in Docker. settings.py DATABASES = { "default": { "ENGINE": "django.db.backends.sqlite3", "NAME": BASE_DIR / "db.sqlite3", } } docker-compose.yaml version: "3.7" services: rabbitmq: restart: always container_name: "rabbitmq" image: rabbitmq:3-management-alpine ports: - 5672:5672 - 15672:15672 app: restart: always container_name: "fbrq_api" build: . volumes: - .:/code command: python3 manage.py runserver 0.0.0.0:8000 ports: - "8000:8000" celery: restart: always container_name: "celery" build: context: . command: celery -A fbrq_api worker -l info env_file: - ./.env depends_on: - app - rabbitmq environment: - CELERY_BROKER_URL=amqp://guest:guest@rabbitmq:5672/ celery.py import os from celery import Celery os.environ.setdefault("DJANGO_SETTINGS_MODULE", "fbrq_api.settings") app = Celery("fbrq_api", broker="amqp://guest:guest@rabbitmq:5672/") app.config_from_object("django.conf:settings", namespace="CELERY") app.autodiscover_tasks() @app.task(bind=True, ignore_result=True) def debug_task(self): print(f"Request: {self.request!r}") I understand that SQLite is not the best choice, but I think it's not about the database itself, but about the connection between Celery and the database. -

In Django how can i execute multiple if/else conditions in a function and print their result to a div?
I would like to execute some multiple conditions (if/else) in the def function_check function and print their multiple result in a grey div, for example like this: Initially i had all the code in the same function, now i have divided it into two functions and mentioned the difficulties, so i want to continue using 2 separate functions: def function_input_user and def function_check. Precisely, the app checks if there are words in a textarea (user_input.html). If there are, then I would like to print a message in the grey div. I'm new to Django, my difficulties are with context and return JsonResponse(context, status=200), because i can't return all multiple condition results and print them in the colored div.

Try to Display Number of Choice Selected at Any Time on Django Form MultipleChoiceField
I am building an application for a real estate project. As part of this, I have "listing" items in my database that I filter and display on my SearchTool.html page. One of the search functions includes a button that says "Select Property Type" on it. When you click the button, a small popup displays all of the multiple-choice field options from my Django form. I want the button to show how many choices are selected so that if the popup is closed you don't have to reopen it to know how many are active. Currently, it seems to mostly work. The popup works great. But, the counter has some problems. When I select exactly on the checkbox then the counter works fine but when I select the text to toggle the choice the counter doesn't catch it. When I click on the text like this, the backend still registers it because it sorts my listings correctly. So, there is an issue with the html/js not registering when I select the text vs the box itself. I am new to Django so please let me know if this question has been answered or if I am missing something obvious. Here is … -
Problem understanding serializer.data structure
I need some help from someone with better knowledge than myself, to understand this. I have a queryset of data and some context data that I send into a rather complex ModelSerializer. The Modelserializer adds (using the context data) fields to the data that doesn't come from the model itself. When I then look at serializer.data it looks like [OrderedDict([('field1', value1), ('field2', value2),....]),OrderedDict([('field1', value1), ('field2', value2),....])] when I drill down into next level for item in serializer.data: print(item) Output: OrderedDict([('field1', value1), ('field2', value2),....]) how can I access value1, value2 ? if I iterate in next level it only generates the key values,'field1','field2' etc for i in item: print(i) Output: 'field1' I understand there might be much better functions. But I'm doing it this very simple way to try to understand the structure of the data (without success aparantly). I hope someone understands my question and is able to explain to me. I've been playing around with deserialisation but I suspect the structure of the modelserializer doesn't allow it to be used. Is it correct that deserialisation only work on datasets that are 100% generated from the model in the Modelserializer in question? -
Seperated Django frontend and Django backend?
So I am creating my first django project for work and I think I am getting familar with it. I designed my views and URLs strongly oriented to REST principles. But since I render html and use forms to manipulate data, it is actually not REST in terms of pushing or pulling data. I have actually no desire to create a separated frontend in a different framework running at a different adress. But I wondered if it would be a reasonable idea to create an app frontend in my project and make all the other apps serve and receive json to make them restfull. Then I could use the frontend app to render the templates and query the data from the other endpoints. But maybe it's a stupid idea for reasons I don't see or I am unsure about. -

Your order ID is {order.id}.' mail_sent = send_mail(subject, message, 'admin@myshop.com', [order.email]) return mail_sent # orders/views.py from django.shortcuts import render from .models import OrderItem from .forms import OrderCreateForm from cart.cart import Cart from .tasks import order_created def order_create(request): cart = Cart(request) if request.method == 'POST': form = OrderCreateForm(request.POST) if form.is_valid(): order = form.save() for item in cart: OrderItem.objects.create( order=order, product=item['product'], price=item['price'], quantity=item['quantity'] ) cart.clear() order_created.delay(order.id) return render(request, 'orders/order/created.html', {'order': order}) else: form = OrderCreateForm() return render(request, 'orders/order/create.html', {'form': form}) i imported celery in my project , and want to create an asynchronous task, after reading celery docs i think i do everything right , and still delay method does not exist Django==5.0.1 celery==5.3.6
