Is there a way to filter django submodel dropdowns to only appear for the current user?
I have a main model named Event. This event has a submodel named Pogram, and the Program model has a submodel called DetailedProgram. I have been able to filter the app to make sure that only the logged in user can post for themself. Also, I have managed to make the user only access Events created by the loged in user. However, I am struggling to find a way to make the user logged in only access the submodel Program's objects as all the object's are being displayed. Please advise. I tried using the very filter (user filter) used on the Program model but to no avail -

How to serve static files from different locations in NGINX
I want to serve static files from different two Django apps. one static files for the admin app and other static files for the pages app. Note: I am aware of collectstatic command. What I would like to know is that, if there is a way to serve static files from two different directories under /static/ location. If one location failed, check the other location. Locations for static files: /webapps/project/admin/static and /webapps/project/pages/static location /static/ { alias /webapps/project/admin/static/; alias /webapps/project/pages/static/; } This raise an error of duplicate alias directive Here is what I wish to have. To check the files in @static, if file not found check in the @static2 block. server { server_name x.x.x.x; client_max_body_size 8M; access_log /webapps/logs/project/nginx-access.log; error_log /webapps/logs/project/nginx-error.log; location /static/ { try_files $uri @static @static2; } location @static { root /webapps/project/pages/; } location @static2 { root /webapps/project/admin/; } } How should I serve both static files from two directories. -
Trouble deploying Django app to AWS Elastic Beanstalk

Nginx configuration not working correctly with gunicorn
I have a Django app hosted on a GCP instance that has an external IP, the Django is running using Gunicorn on port 8000, when accessing the Django using EXTERNAL_IP:8000 the site works perfectly, but when trying to access the Django using EXTERNAL_IP:18000 the site doesn't work(This site can’t be reached), how to fix the Nginx configuration?

How do I create/update/retrieve multiple Models in one View in Django Rest Framework
I have a Business model and Order model. Businesses can order furniture in our website. A user creates an account and makes an order. Since he is a new user, he is not associated to any Business. In the order form, he will give the information about his business and some information related to current order. A new Business record and Order record will be created with the given info. There's a foreign key for Business in Order table. If he wants to create a second order, since he has already a business, he will have the business info pre-filled in his form. When he gives the order data and submits, backend won't create a new Business record. It only creates Order record and store the Business reference. How do I achieve this in single endpoint to create update and retrieve? # serializers.py import time class BusinessSerializer(serializers.ModelSerializer): class Meta: model = Business fields = '__all__' def create(self, validated_data): timestamp = int(time.time()) random_number = random.randint(100,999) validated_data['code'] = f'BUSINESS-{timestamp}' validated_data['status'] = 'CREATED' return super().create(validated_data) class OrderSerializer(serializers.ModelSerializer): class Meta: model = Order fields = '__all__' def create(self, validated_data): timestamp = int(time.time()) random_number = random.randint(100,999) validated_data['code'] = f'ORDER-{timestamp}' validated_data['status'] = 'CREATED' return super().create(validated_data) # … -
Django request process data saving
I have django asgi app. And I want to have POST /routes handling, that would be something like: async def routes(request): if is_first_request_from_user(request): generator = RouteGenerator() save_generator_for_user(request, generator) return await generator.first_generate() else: generator = get_generator_for_user(request) return await generator.further_generate() And RouteGenerator object has state and stores some complex data like heap, maps, sets etc. and it is attached to each user and should be stored in local memory. So how to implement it in django? Should I use some kind of django cache? I'm not really good at python, especially django, and for me the most straightforward solution would be to store some global map {request_id: route_generator}, however while googling nowhere was mentioned such a simple approach -
How to build single query in Django with related models and count
I did not use the Django for a years and tried to modify some old codebase today. I have models: class MetaTemplate(CreatedModifiedBase): type = models.CharField(max_length=200) class Project(CreatedModifiedBase): name = models.CharField(max_length=200, unique=True) members = models.ManyToManyField( User, through=ProjectMembership, related_name="annotation_projects_as_member", blank=True, ) metatemplate = models.ForeignKey( MetaTemplate, on_delete=models.SET_NULL, related_name="project", null=True ) class Dataset(CreatedModifiedBase): name = models.CharField(max_length=200) project = models.ForeignKey( Project, related_name="datasets", on_delete=models.CASCADE ) class Task(CreatedModifiedBase): dataset = models.ForeignKey( Dataset, related_name="tasks", on_delete=models.CASCADE, null=True ) class Completion(CreatedModifiedBase): task = models.ForeignKey(Task, related_name="completions", on_delete=models.CASCADE) annotator = models.ForeignKey( User, on_delete=models.SET_NULL, related_name="annotation_completions", null=True, ) I have a method which returns number of incomplete Tasks. def get_incomplete_tasks(self, user, project_id, target_completion_count) -> int: return ( Task.objects.annotate(counts=Count("completions")) .filter( counts__lt=target_completion_count, dataset__project=project_id, ) .exclude(completions__annotator=user) .prefetch_related( "completions", "completions__annotator", "dataset__project" ) .count() ) Now I want to rework this method and return the number of incomplete Tasks for each of the projects in single query without project_id and target_completion_count passed by user. So basically the same logic but per in one query per Project. I wrote this code: t = Task.objects.filter( dataset__project=OuterRef('id') ) completion_count_subquery = t.exclude(completions__annotator=user).prefetch_related( "completions", "completions__annotator").order_by().annotate( counts=Func(F('id'), function='Count')).values('counts') objects = Project.objects.all().annotate(task_count=Subquery(completion_count_subquery)).prefetch_related("members", "metatemplate") But I am not able to include counts__lt=target_completion_count part in the proper way. Also tried this query t = Task.objects.all().annotate(counts=Count("completions")).filter(dataset__project = OuterRef('id'), counts__lt=OuterRef("target_completion_count")).order_by().values("completions") … -
Google provider not showing up in Django admin and getting ImproperlyConfigured error after setting up django-allauth

Django widget tweaks manually set input field value?
I am looking for an easy way to manually set a form field (ModelForm) value in a Django Template. I've tried this {% render_field my_form.my_field value=200 %} (tried with and without quotes) but it doesn't work, field is still displaying 0. I can't populate those fields in advance (overwriting form initialization in a ModelForm, or similar), because I will need to change input values dynamically later on, based on other input fields (using HTMX). -

Django Rest Framework authentification in viewsets.ViewSet - need different permissions for each method
I'm facing an issue with Django REST Framework and viewsets.ViewSet. I'm trying to use the @permission_classes decorator to secure specific methods within a ViewSet, but it doesn't seem to be working as expected. When I apply the decorator, all methods require authentication, even when I specify different permissions for other methods. However, if I set the permission_classes attribute at the top of the ViewSet, it works as expected, but I need different permissions for each method. Do you have any advice on how I can achieve method-level permissions within a ViewSet? from rest_framework import viewsets from rest_framework.permissions import IsAuthenticated, AllowAny from rest_framework.decorators import action, permission_classes from rest_framework.response import Response class ProjectViewSet(viewsets.ViewSet): # Works as expected: all methods require authentication permission_classes = (IsAuthenticated,) @action(detail=False, methods=['get'], url_path='my') def list_investors_projects(self, request): # This method should be protected but allows access without authentication data = { 'message': "This is a custom GET method!", 'status': 'success' } return Response(data) @action(detail=False, methods=['get'], url_path='public', permission_classes=[AllowAny]) def public_projects(self, request): # This method allows public access data = { 'message': "Public projects", 'status': 'success' } return Response(data) I tried using the @permission_classes decorator above the list_investors_projects method to require authentication and custom permissions.

Mapping DRF GenericViewSet to http verbs via DefaultRouter
My goal is to implement adding a recipe to current user favorites list and removing it using Django Rest Framework 3.12.x. POST api/recipes/{int:recipe_id}/favorite DELETE api/recipes/{int:recipe_id}/favorite Request body is empty. User_id is got from self.context['request'].user.id. I.e. I need to serve POST and DELETE on the same URL. I implemented that against DefaultRouter in conjunction with GenericViewSet, but can't get this implementation serving DELETE. Only POST is served properly. The quesrtion is: what's wrong in the configuration? Why DRF returns 405 "Method Not Allowed" on DELETE calls and returns Http header Allow: POST, OPTIONS?

DjangoAdmin: Use InlineModels without a parent model
I have a model (e.g. Contact with two fields, email and name). I'd like to add a custom view to Django Admin that allows for batch creation of multiple contacts.

Is there a way to reuse the inline-code from Django admin to add a custom view for batch adding multiple contacts?

Django app; Default User ID and model field 'Trader ID' not equal
I am creating an app to allow users to enter stock trades, for record keeping. I am using Django's default User model for login and authentication. My intention is to allow the logged in user to view only their own 'Entries', which is my model for stock record entries. To this end, I have created a one to Many relationship in my Entry model named 'trader' which points to the User ID (they should be the same). After logging in though, I don't see ANY trades on the screen even though they have been entered. I checked the Database, and the Entry.trader.id is the same number as the User.id (1 in the case of the first user created). Very strange. What I tried: I tried removing this line from my views.py EntryView class: entries = Entry.objects.filter(trader_id=logged_in_user).order_by("entered_date") and replacing it with: entries = Entry.objects.all() This works (proving that the records are there)but now it shows ALL of the entries. My models.py: from django.db import models from django.core.validators import MinValueValidator, MaxValueValidator from django.urls import reverse from django.utils.text import slugify from django.contrib.auth.models import User class Entry(models.Model): ONEORB="1-Min ORB" FIVEORB="5-Min ORB" ABCD="ABCD" REVERSAL="Reversal" PROFIT="Profit" LOSS="Loss" RESULT_CHOICES = ( (PROFIT, "Profit"), (LOSS, "Loss") ) STRATEGY_CHOICES … -
django forms.ModelChoiceField not populating for edit form
I'm using same view and template for adding and editing the record in django. when I click on edit, all other fields are populated correctly, but modelChoiceField has no value. I've tried the solution Django ModelChoiceField is not filled when editing but not getting the desired results. Here's how I'm defining the field in model category = forms.ModelChoiceField( queryset=Category.objects.all(), empty_label="Select Category", required=True, to_field_name="name" ) Here's how I'm initializing my form form = myForm(request.POST or None, instance=form_instance, initial=models.model_to_dict(form_instance)) if I print the output from model_to_dict(form_instance) it show {'id': 18, 'title': 'test title', 'description': 'test description', 'material': 'blah blah', 'category': 2, 'user': 3} But on the form, model choice field has empty label. How do I populate it with NAME for category having pk=2 in above case ? -

best method to do Django facial recognition by capturing the customer's
Good afternoon, what would be the best way to capture frames from the user's camera to use a function I have in Django views for facial recognition. What I'm trying now is to open a camera for the user on the web and from there remove the frames, but it's not working correctly as it's giving me the error "TypeError: Object of type bytes is not JSON serializable" and also I wanted the user to have that frame around the face saying that the image is being captured. I will send below what I have in views and in my js I appreciate any help or opinion offered @csrf_exempt def process_frame_faceRecognition(request): print("Processando frame...") if request.method == 'POST': frame_data = request.POST.get('frame_data') print(frame_data) frame_data = frame_data.split(',')[1] # Remover o prefixo 'data:image/png;base64,' frame_data_decoded = base64.b64decode(frame_data) frame_data = np.frombuffer(frame_data_decoded, dtype=np.uint8) frame = cv2.imdecode(frame_data, flags=1) # Agora você pode passar o frame para a função compare_faces() face_recognition = FaceRecognition() result = face_recognition.run_recognition(frame) # Verifique o tipo de resultado antes de retorná-lo if isinstance(result, HttpResponseRedirect): return JsonResponse({'message': 'redirecionamento', 'url': result.url}) else: # Coleta os valores do generator em uma lista result_list = list(result) # Codifica a imagem como base64 _, buffer = cv2.imencode('.png', frame) frame_base64 = …
