Django DRF filtering fields in serializer
I'm new to Django DRF and I'm trying to write a more organized code since the one below lacks the correct approach. I have 2 API endpoints: /api/order/info - which shows all the order fields /api/order/status - which shows only one field At the moment I have two serializers and two views as follows: serializers.py class OrderSerializer(serializers.ModelSerializer): class Meta: model = Order fields = ['order_id', 'data', 'status'] class OrderStatusSerializer(serializers.ModelSerializer): class Meta: model = Order fields = ['status'] views.py # /api/order/info - retrieves all fields class OrderInfo(generics.RetrieveAPIView): queryset = Order.objects.all() serializer_class = OrderSerializer def get_object(self): try: return Order.objects.get(pk=self.request.data['uuid']) except Order.DoesNotExist: raise Http404 # /api/order/status - retrives just one field, the status class OrderStatus(generics.RetrieveAPIView): queryset = Order.objects.all() serializer_class = OrderStatusSerializer # a serializer just for this def get_object(self): try: return Order.objects.get(pk=self.request.data['uuid']) except Order.DoesNotExist: raise Http404 The problem: the code works as expected, but it is pretty clear that it is duplicate! I'm creating a new serializer for just filtering one field, but I strongly believe that DRF makes this easier in some way. Could you please suggest a better approach? Thanks -
Adding related model in separated page Django Admin
The problem is following: All fields are not displayed when I add model for related model using TabularInline but at another side I don't want to use StackedInline, cuz it seems to be not pretty. So, is it possible to use another page to add model for related model, that it automatically will be added to corresponding Partner. Maybe is it possible to use StackedInline for one reason and TabularInline to another, or something similar? Or override adding link? What exactly do I want Displaying: Adding: -
Webhook listener with csrf
I want to create a webhook listener for a third party app. But fot this i have to use @csrf_exempt . Without using the above my web app isn't allowing the third party app to send the webhook data.

Regular expression to validate US phone numbers using Formik and Yup
I'm trying to validate us phone numbers inside my formik form using yep. I found some information on regex here on stackoverflow but it doesn't seem to be working. I basically need to be able to allow brackets, dashes and spaces aswell as the country code. The backend converts everything into something like this: (123) 123-1234 This is what i tried: validationSchema={Yup.object({ AdministratorCell: Yup.string() .matches(/([0-9]{3})[0-9]{3}-[0-9]{4}/, { message: "Invalid phone number", excludeEmptyString: false, }) })} I'm using https://github.com/google/libphonenumber in the backend for backend validation of those phone numbers which is why i need frontend validation to properly work or the form won't submit in some cases where users forget a number or format the number in a certain way. My issue is with what i tried so far is that i can only add the phone number with a certain formatting or it will not submit to the backend. -

Subscribe to google and outlook calendar through url causing problems
I'm working on a project using Django Rest Framework and icalendar. I've created an api which provides ics file for download.

Optimal table design for ELO system
I'm trying to create elo system using django with postgresql. Below description is a system what I imagined. Elo table sorted by Date field. Table have two player's elo data field.

How to write custom authentication backend for one endpoint only (/metrics) in Django?
I have a custom middleware in Django to force all the requests to go through a login authentication (with few exceptions like api/token). This project allows users to authenticate either via a JWT token or a login in /admin/login and all unauthenticated users are redirected to /admin/login. for authentication. We deployed the project in Kubernetes and we want Prometheus to scrape /metrics endpoint but we don't want it to be exposed to unauthenticated users. Prometheus allows for authentication with username and password. The thing is that when a request is sent to /metrics, because of the middleware, the request is redirected to /admin/login. So I believe I need to write a custom authentication backend specifically designed for the metrics endpoint and place it before the other authentication methods. The request always goes through the middleware first so it will always be redirected to /admin/login and then will go through the authentication backend. What is the right way of doing this? middleware.py class LoginRequiredMiddleware(MiddlewareMixin): def __init__(self, get_response): self.get_response = get_response def process_request(self, request): assert hasattr(request, 'user') path = request.path_info.lstrip('/') if path == '' or path == '/': return self.get_response(request) url_is_exempt = any(url.match(path) for url in EXEMPT_URLS) if request.user.is_authenticated or url_is_exempt: # … -

How to pass all field names to when_any argument of django-lifecycle hook
I am using django-lifecycle to create a function in a model to be run when any input is changed. I'm doing this using the before_update hook, e.g. @hook("before_update", when_any=list_of_fields, has_changed=True) def do_something(self): do something here... I am trying to pass all of the field names to the when_any argument but struggling because the hook argument cannot use self to get this. For example doing: @hook("before_update", when_any=[f.name for f in self._meta.get_fields()], has_changed=True) def do_something(self): do something here... gives the NameError NameError: name 'self' is not defined. Is there a way to get all of the model field names in another way from within the model class? -
