Django unable to save FloatField value to 0.0
I have a method on a model that updates a value to 0.0 and calls save(). Problem is save() is never saving the value if it is 0. Here is the code: class Item(models.Model): stock_quantity = models.FloatField( null=True, blank=True, validators=[MinValueValidator(0)] ) class Meta: abstract = True ordering = ["-id"] def mark_as_finished(self) -> None: self.stock_quantity = 0.0 self.save() I have a submodel which extends this one. class Instance(Item): expiration_date = models.DateField(null=True, blank=True) Now the mark_as_finished() is called in the view: @action(detail=True, methods=["patch"], url_name="mark-as-finished") def mark_as_finished(self, request: Request, pk: int) -> Response: pi_instance = get_object_or_404(Instance, id=pk) pi_instance.mark_as_finished() pi_instance.refresh_from_db() return Response( data=self.serializer_class(pi_instance).data, status=HTTP_200_OK, ) Upon running the test the stock value never becomes 0. def test_mark_as_finished(self): pink_ins = self.create_sample_instance() self.assertNotEqual(pink_ins.stock_quantity, 0) url: str = reverse(self.mark_finished_url, kwargs={"pk": pink_ins.id}) res: HttpResponse = self.client.patch(url) self.assertEqual(res.status_code, 200) self.assertEqual(res.data["stock_quantity"], 0) self.assertEqual(res.data["stock_quantity"], 0) AssertionError: 10.5 != 0 I am debugging the program and can see that after the save runs the value is never being saved. If I put the value as 0.1 then it saves. So actually it is not saving 0 value in the float field. I even removed the MinimumValueValidator still it won't save 0 value. -

Django Rest Framework communicating with mobile app instances
I would like to build a REST Service which exchanges JSON messages with instances of a mobile app for registering patron traffic in physical locations of (public and academic) libraries. I plan on using Django Rest Framework, and using Django and DRF for the first time, have some questions (rather, recommendation requests). I have read the tutorials and followed some of them, and it looks very promising indeed. As I am quite confident with Object oriented coding in Python, I will be using class based views. Any reason not to? The intended usage of the system will include many different libraries with their own ids, users and properties. The data model behind is thus fairly complex, and implemented with MySQL. I feel I will have better control on the data exchange, updates inserts and selects, with custom SQL queries, and would like the DRF to handle mostly authentication and the routing of messages to and from the instances of the mobile app. Is this a misconception on my part, and would it be better to let DRF handle all database-involved aspects? Given that I follow the custom SQL approach: As (authenticated) user IDs are interwoven with the rest of the … -

Limit Choices for Charfield
I have a model for all choices in program. Instead of Choices Tuple , i wanna use this table for showing options and validate from table when it's gonna save.

Is there any option to keep it as charfield and validate from another table ? A custom model field or anything else ? -
