Django Rest Framework give me validation error that shouldn't be raised when using Unit Tests
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 … -

In django, when working on multiple new features simultaneously, what is the best way to handle migrations with git? I’m in middle of working on feature1, on its own branch.

UserProfileInfo matching query does not exist Django
I need to have extra information about a person, more than the default User model provides. That's why I've created the UserProfileInfo model that's supposed to hold all this extra info, such as house_number, phone_number, full_name, and community. Now, an instance of UserProfileInfo is created whenever a user registers. But when I run this route called all_books in views.py, I get an error: UserProfileInfo matching query does not exist. Here's my all_books view: def all_books(request): if request.user.is_authenticated: context = { "books": Book.objects.all(), "request": request, "user_profile": UserProfileInfo.objects.get(user=request.user), } else: context = { "books": Book.objects.all(), "request": request, "user_profile": False, } if request.GET.get("context") == "mail_sent": context["mail_sent"] = True return render(request, 'main/all_books.html', context) This error happens only when I've signed in, and not when I'm not signed in. When I head over to the admin, I see that the profile has been created. But I don't understand why this isn't able to get that. -

How to choose one item in many to many relationship as special?
What is the best practice to choose one item from a m2m relationship? Lets say I've got an album of photos: class Photo(models.Model): img = models.FileField() class Album(models.Model): photos = models.ManyToManyField("Photo") But now I also want to pick one photo as a cover. I could use a Foreign Key in Album to one Photo, but then I'd always need to check whether this photo is actually in the photos of that album. Is there a better way? Sorry for the basic question I just somehow can't find the right words to google it. Thanks, Michael -
How to pass Django InMemoryUploadFile to serializer in case with images?
I'm creating an API using Django Rest Framework to save images from file directly or from url. I've got no problem with first case but with second. So, my models looks like this: class Image(models.Model): picture = models.ImageField(upload_to="site_media", blank=True) url = models.URLField(null=True, blank=True, max_length=255) parent_picture = models.IntegerField(null=True, blank=True) @property def name(self): return os.path.split(self.picture.name)[-1] @property def width(self): return self.picture.width @property def height(self): return self.picture.height Next, my serializer class: class ImageSerializer(serializers.ModelSerializer): class Meta: model = Image fields = [ 'id', 'name', 'url', 'picture', 'width', 'height', 'parent_picture' ] The main idea is if you pass the URL while post request, API needs to download image from this URL and store it in database. To do this I overwrote create method in Django Rest Framework ModelViewSet class: from io import BytesIO import urllib import os from django.core.files.uploadedfile import InMemoryUploadedFile from PIL import Image as PILImage from rest_framework import status from rest_framework import viewsets from rest_framework.response import Response from .models import Image from .serializers import ImageSerializer class ImageViewSet(viewsets.ModelViewSet): serializer_class = ImageSerializer queryset = Image.objects.all() def create(self, request, *args, **kwargs): if request.data["url"]: url = request.data["url"] image_extensions = { ".jpg": "JPEG", ".jpeg": "JPEG", ".png": "PNG", ".gif": "GIF" } image_path = urllib.parse.urlparse(url).path image_filename = image_path.split("/")[-1] extension = os.path.splitext(image_filename)[-1] …
