Django + mongodb generates float ids for the users model
I have a Django project integrated with MongoDB through Djongo, I have all mongo related packages updated at the latest release. The issue is Django spits back the id as a float for the user object in different places as I'm highlighting in the following pictures: The issue in the first image occurs when I try to click on any user object from the user's table in the Django admin dashboard. If I try to type the link manually without the ".0" part of it. it opens the page to edit the user object no problem. Here I show how each object link looks like, there's a weird ".0" attached to each id in the link... This issue is generating some problems at other places such as when I try to login this occurs: ['“582.0” value must be an integer.'] I believe all of these issues are caused by the same problem. which is what I'm still not sure about... My users model schema: { "_id" : ObjectId("618d3b0766fa111338fd379e"), "name" : "lab_customuser", "auto" : { "field_names" : [ "id" ], "seq" : 589 }, "fields" : { "date_joined" : { "type_code" : "date" }, "email" : { "type_code" : "string" }, … -

I am creating this API and in determined point of my tests (contract creation endpoint) I am receiving an invalid error. The error says that I am not passing some required attribute to the API when creating a contract, but I am. The weirdest thing is that when I tried to create from the Web browser by hand, the issue wasn't raised and the contract was created I am puting here a lot of codes just for replication purposes, but the code that is really important to see it is the ContractSerializer and the test_contract_creation function Here is my code: models.py from django.core.exceptions import ValidationError from django.db import models from django.core.validators import ( MaxValueValidator, MinValueValidator, RegexValidator, ) from core.validators import GreaterThanValidator, luhn_validator class Planet(models.Model): name = models.CharField( max_length=50, unique=True, null=False, blank=False ) def __str__(self) -> str: return self.name class Route(models.Model): origin_planet = models.ForeignKey( Planet, on_delete=models.CASCADE, related_name="origin", ) destination_planet = models.ForeignKey( Planet, on_delete=models.CASCADE, related_name="destination", ) fuel_cost = models.IntegerField(validators=[GreaterThanValidator(0)]) class Meta: unique_together = (("origin_planet", "destination_planet"),) def clean(self) -> None: # super().full_clean() if self.origin_planet == self.destination_planet: raise ValidationError( "Origin and destination planets must be different." ) def save(self, *args, **kwargs): self.full_clean() super().save(*args, **kwargs) def __str__(self) -> str: return f"{self.origin_planet} - {self.destination_planet}" class Ship(models.Model): … -
Managing django secrets
I am creating a Django web application that will be hosted in AWS. I'm developing on my laptop (Mac) and using docker compose to run a postgres database in AWS as well. Accordingly, sometimes I am using a development database from my Mac in PyCharm, and other times I need to compile and run the docker to test that the functionality works in the container. The challenge I am facing is the management of secrets across all of these locations. It would be ideal to have one "secret vault" which could be accessed at run-time from either within the docker or within PyCharm to keep life simpler. I am familiar with .env files and the manner by which these can be imported, but this also requires me to copy them into the docker container at build time. Is there some "simple yet robust" way to manage this more easily? It feels like having copies of different .env files in different environments presents its own risks. -

Django ModelForm never passes is_valid()
I'm new to Django and I am currently trying to store data entered from a form into a model/database. The bit which I think is causing the issue is that I don't want all the model fields accessible on the form. The model I have has the fields as follows: description = models.TextField() date_referred = models.DateTimeField(default=timezone.now) full_name = models.CharField(max_length=100) email = models.EmailField(max_length=100) phone_number = models.CharField(max_length=17, blank=True) column_number = models.IntegerField() notes = models.TextField() colour = models.CharField(max_length=6) user = models.ForeignKey(User, on_delete=models.CASCADE) The ModelForm I am using is as follows: class ReferralForm(ModelForm): class Meta: model = kanban_item fields = ["item_name", "description", "full_name", "email", "phone_number"] The code inside of the views.py file is this: def submit_referrals(request): form = ReferralForm() if request.method == "POST": form = ReferralForm() print(request.POST) if form.is_valid(): print("VALID") referral = form.save(commit=False) referral.user = request.user referral.column_number = 0 referral.colour = "ffffff" referral.save() else : print ("NOT VALID") As you can see, I am trying to create a model from the form then add the extra fields and then save the model to the database. This is not working as whenever I submit the form my code never gets past the is_valid method on the form. Any suggestions or answers are appreciated as I …
