Creating API to Login User in Django
The main error here is basically django doesn't recognizing authentication outside admin page and my main login view I'm trying to apply authentication in my api, as a way to study apis building in django, I have this view in my api app: @api_view(['POST']) def loginUser(request): data = request.data serializer = UserLoginSerializer(data=data) if serializer.is_valid(): serializer.perform_login() return Response({"Success:", "User logged succesfully"},status=status.HTTP_200_OK) else: print(serializer.is_valid()) return Response({"ERROR":"NO PERMISSION."}, status=status.HTTP_400_BAD_REQUEST) For this view, I have this REST formalizer: class UserLoginSerializer(serializers.ModelSerializer): username = serializers.CharField() password = serializers.CharField() class Meta: model = User fields = ['username','password'] def validate(self,validated_data): user = authenticate(username=validated_data['username'],password=validated_data['password']) if not user: raise ValidationError("user doesn't exist.") validated_data['user'] = user return validated_data def perform_login(self): user = self.validated_data['user'] print(user) login(user) Consider all the prints in the view and in the formalizer a humble way to understand what's happening with The problem is: No Wrong information, no invalid credential, testing and testing through shell, through postman, through everything. username=x password=y, whatever is the data, being valid credentials or not, error is being returned CHATGPT warned me it could be because of importing the AbstractUser function for the User model and not AbstractBaseModel, BUT it's working fine for user authentication in my main view and in django admin -
Why Celery does not executed tasks scheduled as result of @worker_ready signal execution?
I have a dockerized application running Django (Gunicorn) and Celery (both worker and beat - django_celery_beat - one in each container), with Redis, Nginx and Postgres.

django-modeltranslation choice field issue
I'm having a problem using the application django-modeltranslation with a choice field. My model Plan has a field called interval with the following choices: class IntervalChoices(models.TextChoices): DAY = DATE_INTERVALS.DAY, _("Day") WEEK = DATE_INTERVALS.WEEK, _("Week") MONTH = DATE_INTERVALS.MONTH, _("Month") YEAR = DATE_INTERVALS.YEAR, _("Year") class Plan(SoftDeleteBasedMixin): INTERVALS = IntervalChoices interval = models.CharField( choices=INTERVALS.choices, max_length=12, default=INTERVALS.MONTH, help_text="The frequency with which a subscription should be billed.", ) I'm using django-modeltranslation to translate the label and the description of the plan on the admin by directly typing them on the Django Admin, but since those choices are preset I cannot edit them in the Admin. I already used gettextlazy on the choices names and have the translations on the django.po #:plan.py:44 msgid "Day" msgstr "Dia" #:plan.py:45 msgid "Week" msgstr "Semana" #:plan.py:46 msgid "Month" msgstr "Mês" #:plan.py:47 msgid "Year" msgstr "Ano" But when I change both the site or the admin to Portuguese, which is one of the languages I'm translating to the interval is shown in English. This is my translation.py from billing.models.plan import Plan from modeltranslation.translator import TranslationOptions, register @register(Plan) class PlanTranslationOptions(TranslationOptions): fields = ("label", "description") Can someone help me to see how can I proceed with this? -

Django React Communication Api
I have a confusion and it is killing be inside. When we work with website that uses react in frontend and Django in backend, what we do is create APIs in django, and then calls the APIs endpoints in our react app to get data. Then populate our frontend with the response data. But my question is, the api can be used by anybody, if he inspects the source code using dev tool. Because, the APIs are accessible by our react app without any authentication. And it should be so. Because, when someone first enters our website without any authentication credentials, we need to render our first webpage (homepage) and API should also be accessible there. But the same way, a hacker can make a lots of request on that server endpoint and thus effect our server, maybe make our server down. The First page of our site is authentication free. Homepage. Homepage is basically not logged in required. So New people try to access it. Its normal. The thing that is not normal is, if someone tries to access that endpoint outside of the browser. We should make sure the request is coming from client browser. Please help me … -
Cannot get Django ModelForm to display neither connect custom HTML form to database
I am currently creating a Django app that is a rental apartments homepage. It is supposed to have a booking form connected to a database.

Django add to cart not working with product variation
I am building an e-commerce website where both products with variations and products without variation can be sold. So I have a cart view which adds a product to a cart and creates a cart instance, but it is not working now that I have modified it for products with variation. So if a product has variations, eg colors and sizes, users can select the variations, eg red and XL, and the selected variations show up on this section of product_detail.html: <div id="selected-variations" class="mt-5"> <div class="text-title">Selected Variation:</div> <div class="mt-3"> <span id="selected-color">Color: None</span> / <span id="selected-size">Size: None</span> </div> </div> Now what I want is to take those selected variation values from there and then add the product to the cart with the selected values. But in doing so, the js is not working, I think my cart view logic is fine. It all seemed very easy in the beginning, since I am literally printing the selected variation values from the user above, just was supposed to take those values and create a cart instance with them. But now for some reason my main.js code won't accept it. Is there any way to fix this? My models.py: class Business(models.Model): BUSINESS_TYPE_CHOICES = [ … -
Django - Aggregate of an Aggregation
I am working with DRF and am having issues defining my queryset for use in my view class. Suppose I have three models like so: class ExchangeRate(...): date = models.DateField(...) rate = models.DecimalField(...) from_currency = models.CharField(...) to_currency = models.CharField(...) class Transaction(...): amount = models.DecimalField(...) currency = models.CharField(...) group = models.ForeignKey("TransactionGroup", ...) class TransactionGroup(...): ... I want to create a queryset on the TransactionGroup level with the following: for each Transaction in the transaction group, add an annotated field converted_amount that multiplies the amount by the rate on the ExchangeRate instance where the currency matches the to_currency respectively then sum up the converted_amount for each Transaction and set that on the TransactionGroup level as the annotated field converted_amount_sum An example json response for TransactionGroup using this desired queryset (assumes the exchange_rate.rate = 0.5: [ { "id": 1, "converted_amount_sum": 2000, "transactions": [ { "id": 1, "amount": 1000, "converted_amount": 500, "currency": "USD", }, { "id": 2, "amount": 3000, "converted_amount": 1500, "currency": "USD", }, }, ... ] I can get the annotations to work properly on the Transaction model - but trying to then sum them up again on the TransactionGroup level throws the error: FieldError: Cannot compute Sum('converted_amount'), `converted_amount` is an aggregate My … -
How can I E2E test celery task called in async function?
Although not recommended by the celery documentation CELERY_TASK_ALWAYS_EAGER = True option allows E2E testing where celery task is called inside a function with delay() method. async def wanna_test_function_e2e(): #.... logic dummy_task.delay() #<- modifies some db value The problem is when i mix sync function (for django transaction) in celery task: @celery_app.task # type: ignore[misc] def dummy_task() -> None: with tranaction.atomic(): User.object.get(id=1) <- note that this is sync operation The task runs fine locally, the issue is with the testing. With EAGER option, I am unable to run test: raise SynchronousOnlyOperation(message) kombu.exceptions.DecodeError: You cannot call this from an async context - use a thread or sync_to_async. As EAGER option forces celery to run in a main process but it was invoked in async context. If I follow Celery's guide and use pytest-celery without EAGER option: @pytest.fixture(scope='session') def celery_config(): return { 'broker_url': "memory://", 'result_backend': 'rpc', } @pytest.fixture(scope="session", autouse=True) def celery_register_tasks( celery_session_app, celery_session_worker, socket_enabled ) -> None: celery_session_app.register_task(dummy_task) Now there is huge problem: async def test_dummy_task( self, celery_session_worker, celery_register_tasks, ) -> None: ... import asyncio await asyncio.sleep(10) <- without this the remaining test can run before task runs user = await User.objects.aget(id=1) assert user.is_modified <- without sleep this fails! even worse if I … -
Django-MySQL remote connection trouble

Adding frequently used context objects to a view in Django
I have several Django apps within a single project. What I am running into is that I often tend to add the same object(s) to the render call that renders a particular screen. In this example below, I have a view that displays a form with a dropdown of categories that you can choose from. Now I need to add these categories every time I display the create.html page. This is simplified, but imagine I have 6 more views that could potentially show the create.html page, all of them have to remember to add the categories array. def createmeeting(request): if request.method == "POST": categories = MeetingCategory.objects.all() // Some error checking, omitted for this example error_msg = "invalid content" if error_msg: return render(request, "meetings/create.html", { "categories": categories, "error_msg": error_msg, }) else: // Create the meeting here, omitted for this example return redirect("/meetings/profile/") else: categories = MeetingCategory.objects.all() return render(request, "meetings/create.html", { "categories": categories }) Is there a better way of handling cases like this? -

django modelForm : dynamically adjust field according to related field
I've been working on a hospital project exercice and am wondering how to render a given field (model "doctor") according to a speciality selection: user has to select first a medical speciality and according to that one, the doctor's list will be dynamically updated.

Why do I have a Flutter web CORS issue despite having set CORS in django backend
I'm developing a Flutter web application that needs to make requests to a Django backend. However, I'm encountering a CORS error when I try to make a request. The error message is: Access to XMLHttpRequest at '<API_URL>' from origin 'http://localhost:63730' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. I've already set up CORS in my Django settings as follows: INSTALLED_APPS = [ ... 'corsheaders', ... ] MIDDLEWARE = [ ... 'corsheaders.middleware.CorsMiddleware', ... ] CORS_ORIGIN_ALLOW_ALL = True Despite this, I'm still getting the same CORS error. Interestingly, I have other applications built with React and Vue that are able to make requests to the same Django backend without encountering any CORS errors. I'm not sure why my Flutter web application is encountering CORS errors while my React and Vue applications are not. Any help would be greatly appreciated. -

I have uwsgi running on a docker container. Nginx running on host. Current setup: ;uwsgi.ini http-socket=:8080 With docker, I've forwarded the host's 8080 port to containers 8080 port. Nginx is configured like server { listen 443 ssl http2; server_name domain.example.com; location / { proxy_pass http://127.0.0.1:8080; } } This works fine, only problem: my port 8080 is exposed and I can directly request the port on the public IP. I should be able to use domain sockets to mitigate this, but I don't know how the set up would look like. Here's my half attempt: ; uwsgi.ini in container socket=/path/uwsgi.sock # nginx on host upstream prod_server { server unix:///path/uwsgi.sock; } server { listen 443 ssl http2; server_name example.domain.com; location { uwsgi_pass pror_server; } } Since nginx is in host, it will look for the path on host server, is adding the socket as a volume the right way to go? Is there another best practice? How would you recommend the setup? Thank you.
