Unable to process the input data from ModelMultipleChoiceField in Django
I've been trying to process the data captured from a simple Django Model Form, and for some reason, it isn't possible to access the group of items selected under ModelMultipleChoiceField. I'm only able to access only one item from the selected items in the form. The Model: class Student(models.Model): name = models.CharField(max_length=80) subjects = models.ManyToManyField(Subject) house = models.ForeignKey(House, on_delete=models.CASCADE, related_name="students_of_house") The Model form: class AddStudentForm(forms.Form): name = forms.CharField(label="Full Name") house = ModelChoiceField(queryset=House.objects.all()) subjects = ModelMultipleChoiceField(queryset=Subject.objects.all()) The view function to process POST and create a Student Object.: def add_student(request): if request.method == "POST": name = request.POST["name"] house = House.objects.get(id=int(request.POST["house"])) subject_ids = request.POST["subjects"] new_student = Student(name=name, house=house) new_student.save() for sub_id in subject_ids: new_student.subjects.add(Subject.objects.get(id=int(sub_id)) new_student.save() return HttpResponseRedirect(reverse("administration:students")) context = { "add_student_form": AddStudentForm(), } return render(request, "administration/add_student.html", context) Now, I later tried using form = AddStudentForm(request.POST) and if form.is_valid(): route, which made it work successfully. But I'm having a hard time figuring out the reason why the above method isn't working. The code which worked: def add_student(request): if request.method == "POST": form = AddStudentForm(request.POST) if form.is_valid(): name = form.cleaned_data["name"] house = form.cleaned_data["house"] subject_ids = form.cleaned_data["subjects"] new_student = Student(name=name, house=house) new_student.save() for sub_id in subject_ids: new_student.subjects.add(Subject.objects.get(id=sub_id.id)) new_student.save() return HttpResponseRedirect(reverse("administration:students")) context = { "add_student_form": AddStudentForm(), } … -

Django Template Inheritance Issue: {% if %} Block Not Rendering When Extending base.html
Problem Description I'm working on a Django project where I have a form that, when submitted, calculates some results and displays them on the same page. The issue arises when I use a base template (base.html). Without using base.html, everything works perfectly, and the results are displayed correctly. However, when I extend from base.html, the content within the {% if results %}{% endif %} block in my test.html template doesn't get displayed at all. base.html Here is my base.html: <!DOCTYPE html> <html> <head> <title>{% block title %}AbiturTest{% endblock %}</title> {% load static %} <link rel="stylesheet" type="text/css" href="{% static 'main/css/style.css' %}"> <link rel="icon" type="image/x-icon" href="{% static 'main/img/icon.ico' %}"> <link rel="apple-touch-icon" href="{% static 'main/img/icon.png' %}"> <link rel="shortcut icon" href="{% static 'main/img/icon.ico' %}"> </head> <body> <header> <nav> <ul> <li><a href="{% url 'home' %}">Home</a></li> <li><a href="{% url 'test' %}">Test</a></li> </ul> </nav> </header> <div class="container"> {% block content %}{% endblock %} </div> </body> </html> test.html Here is my test.html: {% extends 'main/base.html' %} {% block title %}Test - AbiturTest{% endblock %} {% block content %} <h1>Тест AbiturTest</h1> <form id="test-form" method="post"> {% csrf_token %} <ul> {% for question in questions %} <li>{{ question.text }} <div class="radio-buttons"> <input type="radio" id="q{{ question.id }}_1" class="radio-button" name="answer_{{ question.id }}" value="1" … -
aws app running django static s3 url missing colon wrong url
this is my first post and i was to highlight a problenm that i've struggled with for a whole day. While configuring my django project by recovering the static files from an s3 bucket i've ended up with a problem, the url prefixed in fron of the static resources was generating without : after the protocol, like this: <link rel="shortcut icon" type="image/png" href="https//django-examplebucketname.s3.amazonaws.com/static/images/favicon.png"> so at the css, js and all the other static resources were giving 404. in the tamplate i had: {% load static %} and the settings file instead was configured like that: WS_ACCESS_KEY_ID = "myid" AWS_SECRET_ACCESS_KEY = "mykey" AWS_STORAGE_BUCKET_NAME = "django-examplebucketname" AWS_S3_REGION_NAME = "my-region" AWS_S3_CUSTOM_DOMAIN = "django-examplebucketname.s3.amazonaws.com" AWS_S3_URL_PROTOCOL = "https" AWS_S3_USE_SSL = True AWS_S3_VERIFY = True AWS_LOCATION = "static/" STATIC_URL = "https://django-examplebucketname.s3.amazonaws.com/static/" STATICFILES_STORAGE = "storages.backends.s3boto3.S3Boto3Storage" but the static url was not taken in consideration and once released over apprunning the url was always missing the : (colon) after the protocol no other configurations were applied over the project. With the local setting and whitenoise was working. I've checked: the policy on the bucket --> they were ok (trying to connect directly to a resource via the bucket url was reachable) changing the static_url manually override the static … -

User defined logvars for Django application deployed on uWSGI server
I have deployed a Django application on a uWSGI server, which has the following middleware # myapp/middleware.py from django.utils.deprecation import MiddlewareMixin class LogUserMiddleware(MiddlewareMixin): def process_request(self, request): request.META['REMOTE_USER'] = 'test' The middleware is added in the settings.py file as well # myapp/settings.py MIDDLEWARE = [ ... 'myapp.middleware.LogUserMiddleware', ... ] Then in the uWSGI config file also the logvar is used ... log-format = %(ltime) %(addr){uWSGI} : %(method) %(uri) %(status) %(REMOTE_USER) ... But still the logs show as 19/May/2024:09:01:49 +0000 127.0.0.1{uWSGI} : GET /health_check 200 - Basically the logvar is getting replaced with - instead of showing test Is there any extra config to be done? -

Flatten DRF's nested serializer
I have two models for each user, a User model and a Profile model. class User(BaseModel, AbstractUser): username = None image = models.CharField(max_length=300, blank=True, null=True) email = models.EmailField(unique=True) password = models.CharField(max_length=300) emailConfirmed = models.BooleanField(default=False) phoneNumber = models.CharField(max_length=15, blank=True, null=True) phoneNumberConfirmed = models.BooleanField(default=False) USERNAME_FIELD = "email" REQUIRED_FIELDS = [] objects = UserManager() class Profile(BaseModel): user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='profiles', null=True, blank=True) firstName = models.CharField(max_length=30) lastName = models.CharField(max_length=30) locale = models.CharField(max_length=2) A user can have multiple profiles, but for each locale, a user can have only one profile. And I use these models as a base to create other user models, for example, a Member model: class Member(User): birthdate = models.DateField(blank=True, null=True) class MemberProfile(Profile): member = models.ForeignKey(Member, on_delete=models.CASCADE, related_name='member_profiles', null=True, blank=True) education = models.CharField(max_length=300, blank=True, null=True) address = models.CharField(max_length=300, blank=True, null=True) # other fields only for members Now for the list and create functionalities of this Member model, I've written a ListCreateAPIView like this: @extend_schema(tags=[Namespace.MEMBERS.value]) class MemberListCreateView(generics.ListCreateAPIView): serializer_class = MemberSerializer permission_classes = [IsAuthenticated, IsAdminUser] filter_backends = [filters.DjangoFilterBackend] filterset_class = SearchFilter http_method_names = ["get", "post"] def get_queryset(self): return Member.objects.all() def get_serializer_context(self): context = super().get_serializer_context() context["locale"] = self.kwargs.get("locale", None) return context def create(self, request, *args, **kwargs): return super().create(request, *args, **kwargs) def list(self, request, *args, … -

Is there a better way to update all relation rows with `ForegnKey` relation in `Django ORM`
I have two models, one like this: class PhysicalSensor(models.Model): name = models.CharField(unique=True, max_length=255) def __str__(self) -> str: return self.name class Sensor(models.Model): physical_sensor = models.ForeignKey(PhysicalSensor, on_delete=models.RESTRICT, null=True, blank=True) So, when I want to add a PhisycalSensor record, I want to set the Sensor records to that. Right now I handle this in my Serializer class: class PhysicalSensorSerializer(ModelSerializer): sensors = SensorSerialiazer(required=False, many=True) class Meta: fields = ("__all__") model = PhysicalSensor def create(self, validated_data): sensors = validated_data.pop("sensors") ph_sensor = super().create(validated_data) for sensor in sensors: s = Sensor.objects.get(sensor["id"]) s.physical_sensor = ph_sensor s.save() and for edit of PhysicalSensor, I use the same thing in .update() method of my Serializer. Is there any batter way of doing this or a best practice for this ? -

How to upload and store multiple images in Django 4
Django 4 Need user to be able to upload either an archive of images or just a few images at a time. Then these pages are numbered according to the order in which the user has placed them and stored in the database. Thus, when you open a page with images, there will be all the images just uploaded for this page in the correct order UPD: I would also be grateful if you could tell me how to rename files, change their extension, for example from .png to .jpg and in the path of saving in the model, for example, poster = models.ImageField(upload_to=‘posters/’, blank=False, null=False, verbose_name=‘Posters’) in the attribute upload_to add a value depending on what page the images are uploaded to. For example, if the page is called ‘opera’, the image path would be ‘posters/opera/1.jpg’, ‘opera/2.jpg’, etc. For the ‘Romeo and Juliet’ page it would be ‘posters/Romeo-and-Juliet/1.jpg.’ -

[Nginx][Django] Cannot access the media files in production via Nginx
I am trying to access the media files using Nginx. The file exists in the directory: /usr/src/app/backend/media/profile/c4ebe33d-7da1-4a62-bb17-8da254d69b36, where the part profile/c4ebe33d-7da1-4a62-bb17-8da254d69b36 is created dynamically. The media root is: /usr/src/app/backend/media. I know the file exists cause I am able to see it in the container.
