Django REST Framework - the best way to use POST request to other model API endpoint?
I have two models - with users profiles and with events. When the user profile is creating, I want to create for him the timetable with events. When I get the events[] list - I want to send all events using POST to Event model API's in url 127.0.0.1:8000/api/all-events/. What is the simplest way to do that? Event models.py: class Event(models.Model): user_name = models.CharField(max_length=128, default='') event = models.CharField(max_length=128, default='') date = models.DateField(default='') Profiles view.py: class ProfilesList(generics.ListAPIView): queryset = Account.objects.all() serializer_class = AccountSerializer filter_backends = [DjangoFilterBackend] filterset_fields = ['user_name'] def post(self, request, format=None): saveserialize = AccountSerializer(data=request.data) if saveserialize.is_valid(): saveserialize.save() timetable = Timetable(request.data["user_name"], 2021) events = timetable.create_timetable() for event in events: // Here I want to put the .post request to every event. I want to send // {'username': event[0], 'event': event[1], 'date': event[2]} to // Event model API's on url /api/all-events/ return Response("it's working") -

How can I a Djanog auth user on the command line and not have to manually enter the password?
I'm using Django 3.2 and the auth module. I would like to create a super user on the command line (for eventual inclusion in a docker script).

Math in Django ORM and SQLite: decimal ignored if round number, correct result if not round
In a complex query, I have an annotate like this one: result.annotate(test=ExpressionWrapper(485.00 / F( 'period_duration' ), output_field=DecimalField())) This gives me the correct result: Decimal('8.01917989417989E-10') However, if I replace 485.00 with 485: result.annotate(test=ExpressionWrapper( 485 / F( 'period_duration' ), output_field=DecimalField())) I get: Decimal('0') This wouldn't be a problem, if it wasn't that 485 also comes from a field, called "value". My query looks like this: result.annotate(test=ExpressionWrapper( F( 'value' ) / F( 'period_duration' ), output_field=DecimalField())) Value is a MoneyField, basically just a fancy wrapper around DecimalField. I can force my users to always use proper decimals (485.00 as opposed to 485), which in itself would be bad design but... even then, if the database value is 485.00, Django behaves as if it is 485 and thus returns 0 while doing floating point math. I have tried Casting value to a DecimalField, to no avail. result.annotate( res=ExpressionWrapper( Cast('value', output_field=DecimalField()) / F( 'period_duration' ), output_field=DecimalField() )).last().res Result is always: Decimal('0') Instead of the correct one: Decimal('8.01917989417989E-10') How can I force Django to always use floating point math? p.s. period_duration is 604800000000, if it's of any help. -

Add multiple "Place of Interest" model to a "Tour" model in Django and allow one "Place of Interest" to be in multiple "Tour" model
What is the best way to represent this situation: I want to create a tour app that consists of "Tour" and "Place of Interest" The "Tour" model would have multiple "Place of Interests". One "Place of Interest" should be able to be added to multiple "Tour". I can't wrap my head around this. So far, I can only add one "Place of Interest" to one "Tour" Here's my model: class PlaceOfInterest(models.Model): name = models.CharField(max_length=255) tour = models.ForeignKey("Tour", on_delete=models.CASCADE, related_name="tours", blank=True, null=True) class Tour(models.Model): title = models.CharField(max_length=255) Any pointer would be greatly appreciated. Thanks in advanced. -
Script returns an empty list data with 200 response, fetching data from django backend
I am working on an autocomplete app that I want users be able to make address search through the backend of Django but somehow the Api doesn't fetch data through the script, why is the payload show any data in the log console but rather an empty list?, I have tried calling the data from the browser as in example http://127.0.0.1:8000/search/?address=val , which fetches the json data response with a payload of data of addresses that match my search, but when i pass the url in my javescript it returns an empty data list with a 200 response. My experience in Js is mediocre, since I'm a novice. <script> new Autocomplete('#autocomplete',{ search : input => { console.log(input) const url = "/search/?address=${input}" return new Promise(resolve => { fetch(url) .then( (response) => response.json()) .then( data => { console.log(data) resolve(data.data) }) }) }, onSubmit : result => { console.log(result) window.open('/search/?address=${result}') } }) </script> my view for search def search_address(request): address = request.GET.get('address') playload = [] if address: fake_address_objs = Address.objects.filter(address__icontains=address) for fake_address_obj in fake_address_objs: playload.append(fake_address_obj.address) return JsonResponse({'status':200 , 'data': playload }) Returned empty data in the console log Returned data in browser using http://127.0.0.1:8000/search/?address=v -
