Send variable to Django crispy forms
I have a Django Crispy form defined in views.py: @login_required def PostCreate(request): if request.method == 'POST': form = PostFileForm(request.POST or None, request.FILES or None) files = request.FILES.getlist('file') if form.is_valid(): post = form.save(commit=False) post.author = request.user form.instance.author = request.user etc. and post_form.html: {% extends "blog/base.html" %} {% load crispy_forms_tags %} {% block content %} <div class="content-section"> <button class="btn btn-outline-info" id="audit" onclick="audit()">Basic</button> <form method="POST" id="PostForm" data-sektor-url="{% url 'ajax_load_sektors' %}" data-department-url="{% url 'ajax_load_departments' %}" data-person-url="{% url 'ajax_load_persons' %}" novalidate enctype="multipart/form-data"> {% csrf_token %} <fieldset class="form-group"> <legend class="border-bottom mb-4" style="color:red;">Order</legend> {{ form|crispy }} </fieldset> <div class="form-group"> <button class="btn btn-outline-info" id="submit" type="submit">Submit</button> </div> </form> in my models.py I have defined all models I need for the full form. Depending on the 4 buttons which user can click to call the form, that form should have some fields hidden/shown or autofilled. I hide them using Javascript, for example: <script type="text/javascript"> function on_load(){ document.getElementById('hidden_on_open').style.display = 'none'; My problem is, I don't know which button is pressed. Is there a way to 'pass a static variable' or something to the HTML, since if I pass it to views.py it's already rendered? So that I can use Javascript to hide/show and autofill certain fields depending on that variable. Just … -
Django ORM efficient way for annotating True on first occurrences of field
I have a situation where we have some logic that sorts a patient_journey queryset (table) by some heuristics. A patient_journey has a FK to a patient. I now need an efficient way of setting True for the first occurrence of a patient_journey for a given patient, false otherwise. The first heuristinc is patient_id so the queryset will already by grouped by patient. The algorithm is v straight forward & should be fast, yet I'm stuck at trying to get something <1s. I've tried using distinct and checking for existence, however that's adding 1-2s. I've tried using a subquery with [:1] & test on id, but that's even worse around 3-5s extra. def annotate_primary( *, qs: 'PatientJourneyQuerySet' # noqa ) -> 'PatientJourneyQuerySet': # noqa """ Constraints: -------------- Exactly One non-global primary journey per patient Annotations: ------------ is_primary_:Bool, is the primary_journey for a patient """ from patient_journey.models import PatientJourney qs = get_sorted_for_primary_journey_qs(qs=qs) # cost until now is around 0.17s # using distinct on patient_id & checking if id is in there adds around 1.5-2s # looking for something faster, i.e. this shoiuld be a straight forward scan. qs = qs.annotate( # True for first occurrence of a `patient_id` false otherwise primary= ) … -

How do I use prefetch_related for Generic Relationship in Django?
I've multiple models. Model1, Model2, Model3, ... Each model requires multiple let's say feature/images. Can be implemented by making different Image models ( i.e. Morel1Image ) then link with foreign key. Or, Make a Generic Image Model and use it wherever it needs. The problem is, I'm having similar queries ( debug ). And prefect_related isn't working ( Django might not have the feature ). Now how do I solve the problem ( efficiently ) ? I'm expecting no similar or duplicate quary. -

How i run a program in background in django without loading page
i am working on a project which has a function which generate response automatically on loop using google gemini api and show it to the html page by saving it to the database, i want this function to run in background all the time without loading the page Currently what is happening is, if the function is generating 10 response in a loop then it is keep loading the page until all response get generated and then it is showing me home.html page. Someone told me to use command management and i made the command, but i dont know how this command is going to run a function automatically in background on starting a server. i am providing a example command code, suppose i want to run it in background withouth loading a page, what should i do. from django.core.management.base import BaseCommand from main.models import Data1 data1 = Data1.objects.all() class Command(BaseCommand): help = 'Displays stats related to Article and Comment models' def handle(self, *args, **kwargs): for data_test in data1: print(data_test) -
How to get an attribute of a serializer class in DRF?
I have a serializer class CourseSerializer. A course can have a number of groups, lessons and etc.. A code for a serializer: class CourseSerializer(serializers.ModelSerializer): lessons = MiniLessonSerializer(many=True, read_only=True) lessons_count = serializers.SerializerMethodField(read_only=True) students_count = serializers.SerializerMethodField(read_only=True) groups_filled_percent = serializers.SerializerMethodField(read_only=True) demand_course_percent = serializers.SerializerMethodField(read_only=True) def get_lessons_count(self, obj) -> int: return obj.lessons.count() def get_students_count(self, obj) -> int: amount = Subscription.objects.filter().count() return amount def get_groups_filled_percent(self, obj) -> int: counts = [group.users.count() for group in obj.groups.all()] return ((sum(counts) / len(counts)) / 30) * 100 def get_demand_course_percent(self, obj) -> int: users = CustomUser.objects.all().count() students = Subscription.objects.filter().count() return (students / users) * 100 As you see, a serializer has calculated attributes like lessons_count, students_count ad etc.. The question is: how can I get one of these attributes in a serializer method, for example: def get_demand_course_percent(self, obj) -> int: users = CustomUser.objects.all().count() return (self.students_count / users) * 100_ If I do like this explicitly, it gives an Attribute error that there's no such attribute in a serializer class -
Incorrect inharitance of objects in django python app

Unable to update latest database configuration in settings.py in django
I write code on my local machine and then use github to transfer the code to my Amazon AWS EC2 server, I am using AWS Route53 to connect to a domain name and AWS RDS for database (started using recently, few days ago). In my previous code I was using Hostinger's remote mysql capability for a hosted database which was working fine, I deployed the code on AWS EC2 server and tested, however, when I created MySql database using RDS and updated its details in the settings.py the application is still being run using the old Hostinger's database settings only. I have tried the following things: deleting all the cache files, removing all migrations files and creating migrations once again, checked settings.py (database configuration settings) multiple times Restarted the EC2 instance, restarted supervisor, gunicorn, nginx Deleted the RDS database and created one more and updated its respective settings in settings.py To my surprise, for some reason it is still working on the old database, I am not able to figure out where exactly is it picking up the details of the old database and why is the latest settings.py file not being loaded in real time? -
Why is Django App Not Rendering HTML Page
Hello I am using Django version 4.2.3 to build my website for building my website. I have an Object called UE (upcoming_events) that I have added several fields to however, these fields don't seem to be rendering when I call the object instead the words No Events render which only happen when the upcoming_events object is empty. In order to see why this is happening I used the Django Shell to visualize the code post processing. But in the visualization the code seems to populate the objects just fine just not when rendering the object on the website. {% extends "webapp/header.html" %} {% block content %} <div class = "centerbody"> <div class="liner"> <!--Carousel Starts--> <div class = 'dive'></div> <div class = float_col> <div id="carouselExampleFade" class="carousel slide carousel-fade span" data-ride="carousel"> <div class="carousel-inner carouselMargin1"> <div class="carousel-item active"> <img src="/static/images/CarouselPictures1/canyonphoto1.jpg/" class="d-block w-100 carouselImgs" alt="..."> </div> <div class="carousel-item"> <img src="/static/images/CarouselPictures1/canyonphoto2.jpg" class="d-block w-100 carouselImgs" alt="..."> </div> <div class="carousel-item"> <img src="/static/images/CarouselPictures1/canyonphoto3.jpg/" class="d-block w-100 carouselImgs" alt="..."> </div> </div> <a class="carousel-control-prev" href="#carouselExampleFade" role="button" data-slide="prev"> <span class="carousel-control-prev-icon" aria-hidden="true"></span> <span class="sr-only">Previous</span> </a> <a class="carousel-control-next" href="#carouselExampleFade" role="button" data-slide="next"> <span class="carousel-control-next-icon next_button" aria-hidden="true"></span> <span class="sr-only">Next</span> </a> </div> </div> <div class="announcements"> <h2>Announcements</h2> <div class="announcement-container"> {% for announcement in announcements %} <div class="announcement-item"> <img … -
Django Choice Dropdown Not Working on Cloned Form in Formset
I am cloning my an empty form in django following guidance I've found elsewhere in stack overflow. The JS will append a new form as intendended however the dropdowns from a choice widget are no longer working and I can't figure out why. I have already validated that all of my options are there using my browser's inspect feature. It appears to be that the javascript isn't working with the object.

Do Django generic views automatically generate templates for Django models?
That’s all the Python code we need to write. We still need to write a template, however. We could explicitly tell the view which template to use by adding a template_name attribute to the view, but in the absence of an explicit template Django will infer one from the object’s name. In this case, the inferred template will be "books/publisher_list.html" – the “books” part comes from the name of the app that defines the model, while the “publisher” bit is the lowercased version of the model’s name. This comes from https://docs.djangoproject.com/en/5.1/topics/class-based-views/generic-display/ after the PublisherListView is displayed and the URL is configured. I have several questions: By changing the model equal to publisher, I understand that this view looks at a template books/publisher_list. Is this template already created by Django, with default code/logic to handle the display of multiple items of the given model? Or do we need to write it ourselves, with the context object_list? To be clear, if we create any generic view which inherits from ListView, and pass it a Django model as an attribute, will the template it's assigned to (if it already exists) look at all instances of that model, and display them in some pre-written … -
Django REST Framework cached view returning 2 different payloads
I'm experiencing a strange issue with my Django REST Framework paginated list view, which utilizes a 2 hour cache. If I repeatedly make requests to the view's endpoint, I am sometimes getting Response 1 (x bytes in size) and sometimes getting Response 2 (y bytes in size). The view code is as follows: class MyListView(generics.ListAPIView): model = MyListModel serializer_class = MyListSerializer pagination_class = PageNumberPagination pagination_class.page_size = 1000 def get_queryset(self): region = self.kwargs.get('region') sort_param = '-date_created' return MyListModel.objects.filter(region=region).order_by(sort_param) @method_decorator(cache_page(2*60*60)) def get(self, *args, **kwargs): return super().get(*args, **kwargs) I'm not sure if this is relevant, but once a day, I run a cronjob which clears all cached views using the following code: from django.core.cache import cache cache.clear() I have confirmed that the difference in response data from this endpoint is not due to the cache expiring and being replaced with new data. I have also confirmed that the data in the database for MyListModel is not being changed at all. I have also confirmed that the region parameter is consistent between requests. I'm at a loss for how I could be getting 2 different responses from this endpoint. Cache or no cache, the underlying data is not changing so the response should be … -

Django Mock database not working properly
I was coding a unit test method for a post method, but for some reason, it keeps modifying the actual database instead of the mock database. This is my test method: def test_post_contest(self): mock_collection = self.mock_db.collection.return_value mock_document = mock_collection.document.return_value mock_document.set.return_value = None response = self.client.post( reverse('contest-list'), data={ 'ONI2024F2': { 'name': 'ONI2024F2', 'problems': ['problem1', 'problem2'], 'administratorId': '0987654321' } }, format='json' ) self.assertEqual(response.status_code, 201) self.assertEqual(response.json(), {'id': 'ONI2024F2'}) This is the setUp method: def setUp(self): self.client = APIClient() self.mock_db = patch('firebase_config.db').start() self.addCleanup(patch.stopall) And this is the firebase_config.py file import os import firebase_admin from firebase_admin import credentials, firestore #Path to Firebase credentials cred_path = os.path.join(os.path.dirname(__file__), 'credentials','firebase_credentials.json') #Initialize Firebase cred = credentials.Certificate(cred_path) firebase_admin.initialize_app(cred) #Firestore client db = firestore.client() I thought that it could be the firebase-config file, so I tried changing it but then all the tests raised exceptions. -

How to pass a related objects parameters in the main objects serializer
I have a Room object, which will have some settings. I wanted to make Room and RoomSettings different objects but bound to each other. RoomSettings will be created whenever a Room is created, so I'm using signals. However, while creating the room, I need to pass RoomSettings arguments from Room to RoomSettings through signals, so I can set the settings in creation. models.py from django.db import models from users.models import AppUser as UserModel from django.core.validators import MaxValueValidator, MinValueValidator import random, string from datetime import datetime def generate_unique_key(): length = 10 while True: key = ''.join(random.choices(string.ascii_uppercase, k=length)) if Room.objects.filter(key=key).count() == 0: break return key class Room(models.Model): host = models.ForeignKey(UserModel, on_delete=models.CASCADE, related_name='rooms') key = models.CharField(max_length=10, default=generate_unique_key, unique=True, editable=False) created_at = models.DateTimeField(auto_now_add=True, editable=False) def __str__(self): return f'{self.key} - {self.host.username}' def get_chat(self): return self.chat class RoomSettings(models.Model): room = models.OneToOneField(Room, on_delete=models.CASCADE, related_name='settings') max_users = models.PositiveIntegerField(default=8, validators=[MaxValueValidator(8), MinValueValidator(1)]) is_public = models.BooleanField(default=True) users_can_send_message = models.BooleanField(default=True) serializers.py from rest_framework import serializers from .models import Room, RoomSettings from users.serializers import UserSerializer from chats.serializers import RoomChatSerializer class SettingSerializer(serializers.ModelSerializer): class Meta: model = RoomSettings exclude = ['room'] class CreateRoomSerializer(serializers.ModelSerializer): max_users = serializers.IntegerField() is_public = serializers.BooleanField() users_can_send_message = serializers.BooleanField() class Meta: model = Room fields = ['max_users', 'is_public', 'users_can_send_message'] signals.py from django.db.models.signals … -

Model indexing on Choice field in django
i have a model which has a status field of choice field which are pending,approved,cancel,rejected. And i index the field status in my model and the makemigrations but the index only works for other values but not approved value. if i filter by other status like, pending,cancel it will shows that it get it from the index but if i filter by approved it won't work and it will load slowly. Though the dataset of the model is much which is around 7million. I get the details from a django debug tools this will show if i filter by other values if i filter by other values if i filter by approved value this is my view which i use to test the filter def testing(request): context['response'] = Task_Submitted.objects.filter(status='approved') return render(request, 'testing.html', context) is there any way to fixed this so approved too will be in index so if i filter by approved value too it will load faster
