Django: How to Represent and Query Symmetrical Relationships for a Family Tree?
I am building a family tree application in Django where I need to represent and query marriages symmetrically. Each marriage should have only one record, and the relationship should include both partners without duplicating data. Here's the relevant model structure: class Person(models.Model): first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) spouses = models.ManyToManyField( 'self', through="Marriage", symmetrical=True, related_name="partners" ) class Marriage(models.Model): person1 = models.ForeignKey(Person, on_delete=models.CASCADE, related_name="marriages_as_person1") person2 = models.ForeignKey(Person, on_delete=models.CASCADE, related_name="marriages_as_person2") start_date = models.DateField(null=True, blank=True) end_date = models.DateField(null=True, blank=True) I want to: Ensure both partners appear as spouses for each other symmetrically. Avoid duplicate entries for the same marriage. Efficiently query all spouses of a person. Here’s the code I’m using to query spouses: # Query spouses for a person p1 = Person.objects.create() p2 = Person.objects.create() Marriage.objects.create(person1=p1, person2=p2) p1.spouses.all() # Returns list containing p2 p2.spouses.all() # Returns empty list However, I’m facing challenges: If p1 spouses are queried, it should contain p2 and if p2 spouses are queried, it should contain p1 Both queries are not symmetrical Questions: Is my model structure correct for representing marriages symmetrically? If not, what improvements should I make? How can I efficiently query all spouses of a person in a database-optimized way while ensuring symmetry? -
Django: rest endpoint not found
I am trying to implement a rest endpoint with Django. My views.py is: from django.http import JsonResponse from rest_framework.decorators import api_view from rest_framework.response import Response from rest_framework import status import json from .utils import retrieve_and_detect_faces @api_view(["POST"]) def video_analysis(request): data = json.loads(request.body) timestamp = data.get("timestamp") return JsonResponse({....}) And in urls.py: from django.urls import path from .views import video_analysis urlpatterns = [ path('video_analysis/', video_analysis, name = 'video_analysis') ] But when I try to call this endpoint, I get error: Not Found: /video_analysis [24/Jan/2025 07:37:26] "POST /video_analysis?timestamp=1234567 HTTP/1.1" 404 2262 What configuration am I missing in my program? -

BadRequest can't return JSON?
I am trying to return a JSON object along with a 400 error code. This correctly returns the object (e.g. {"email": ["A user with that email address already exists."]}: return HttpResponse(json.dumps(dict(form.errors.items()))) Whereas these all just returns an unreadable (by javascript) object ([object Object]): return BadRequest(json.dumps(dict(form.errors.items()))) return HttpResponseBadRequest(json.dumps(dict(form.errors.items()))) return BadRequest(json.dumps(dict(form.errors.items())), content_type='application/json') I've tried several other methods of sending an error code but the results were the same. How do I get the readable object along with a 400 Bad Request error code? -
How to configure dynamic language switching for API responses using i18n_patterns in Django?
I am working on a Django project and need to implement multilingual support for my REST API. I want the API to return responses in the selected language based on the URL prefix (e.g., /en/, /ml/) using i18n_patterns. I’ve done the following: In settings.py, I’ve defined the available languages: LANGUAGES = [ ('en', 'English'), ('ml', 'Malayalam'), ] LANGUAGE_CODE = 'en' I’ve added 'django.middleware.locale.LocaleMiddleware' to the MIDDLEWARE setting: MIDDLEWARE = [ ... # other middlewares 'django.middleware.locale.LocaleMiddleware', ] In the project’s urls.py, I’ve used i18n_patterns to ensure the URLs are prefixed with the language code: from django.conf.urls.i18n import i18n_patterns urlpatterns = [ path('admin/', admin.site.urls), path('auth/', include('accounts.urls')), path('app/', include('app.urls')) ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) urlpatterns = i18n_patterns(*urlpatterns) The Issue: While I can specify the language via the URL (e.g., /ml/ for Malayalam), the API responses are not being automatically translated to the selected language. The responses remain in English even when the Accept-Language header or language prefix is set to another language (e.g., Malayalam) What I Expect: I expect the API responses to be auto-translated into the selected language (e.g., Malayalam) based on the URL prefix or Accept-Language header. What I Have Tried: I’ve confirmed that LocaleMiddleware is active in MIDDLEWARE. I’ve ensured that … -

Custom generic istruthy/isfalsy lookup doesn't work on Foreign Keys
In my Django project, I'm in need of a generic istruthy/isfalsy lookup that would work on any type of database field. Example of models.py: class MyModel(models.Model): my_charfield = models.CharField(...) my_decimalfield = models.DecimalField(...) my_datefield = models.DateField(...) my_boolfield = models.BooleanField(...) my_fkfield = models.ForeignKey(...) What I want to be able to do: MyModel.objects.filter(my_charfield__isfalsy=True) MyModel.objects.filter(my_decimalfield__isfalsy=True) MyModel.objects.filter(my_datefield__isfalsy=True) MyModel.objects.filter(my_boolfield__isfalsy=True) MyModel.objects.filter(my_fkfield__isfalsy=True) I have defined two custom lookups to do that: from django.db.models import Lookup, BooleanField, ForeignKey, Field class IsTruthy(Lookup): lookup_name = 'istruthy' def as_sql(self, compiler, connection): lhs, params = self.process_lhs(compiler, connection) if isinstance(self.lhs.output_field, BooleanField): return f"{lhs} = TRUE", params if isinstance(self.lhs.output_field, ForeignKey): lhs = f"{lhs}_id" return f"{lhs} IS NOT NULL", params return f"{lhs} IS NOT NULL AND {lhs} <> ''", params class IsFalsy(Lookup): lookup_name = 'isfalsy' def as_sql(self, compiler, connection): lhs, params = self.process_lhs(compiler, connection) if isinstance(self.lhs.output_field, BooleanField): return f"{lhs} = FALSE", params if isinstance(self.lhs.output_field, ForeignKey): lhs = f"{lhs}_id" return f"{lhs} IS NULL", params return f"{lhs} IS NULL OR {lhs} = ''", params Field.register_lookup(IsTruthy) Field.register_lookup(IsFalsy) These custom lookups work on all fields except ForeignKey. When used on a ForeignKey, the following error is triggered: django.core.exceptions.FieldError: Unsupported lookup 'isfalsy' for ForeignKey or join on the field not permitted I have tried different variations of this code to handle … -
Temporarily load a fixture for development
I would like to create a lot of dummy products for use in development. The dummy products need to be in the development database, in addition to a copy of all of the data that the production database has, so that I can see what the dummy products will look like in the website. How can I do this easily? I've looked into fixtures, but I can't figure out how to "apply" a fixture on top of a copy of the production database, and how I might be able to unapply it when I'm done with that part of development. -
Is this djoser implementation secure?
This question may be too broad for StackOverflow, but I'm not sure where else to go for help. I wrote a simple authentication system in Django with Djoser and its JWT implementation, using jQuery on the frontend. I really don't know what I'm doing though, and I'm about 99% sure I did it wrong and it's totally insecure. First, when a user submits the login form, I send a POST request to retrieve a refresh token and an access token. The refresh token is stored as a cookie, and the access token is stored in sessionStorage: // Post the form $.post("/auth/jwt/create/", $(this).serialize()) // Success: store tokens & redirect .done(function(data) { // Logged in: set redirect path & store tokens if (data.refresh !== "undefined" && data.access !== "undefined") { Cookies.set("refresh_token", data.refresh, { expires: 30, secure: true, sameSite: "strict" }); sessionStorage.setItem("access_token", data.access); } }) I have another simple script that runs every time a page is loaded. There, I verify the access token, attempt a refresh if it's invalid, fetch user data using the access token, then post that user data to the backend to login. This script also logs the user out if on the logout page: // Log in or … -
Data not saved to database
I don't know what's going on here, whenever I try to create a buzz with the status set to Draft (this is also the default status set on the model) Django returns a 302 response and does not saved it to the database. However, when I change the status to Published it just saves it normally on the database. Here's the code to the view def buzz_create(request): form = BuzzCreateForm() if request.method == 'POST': form = BuzzCreateForm(data=request.POST) if form.is_valid: buzz = form.save(commit=False) buzz.author = request.user buzz.save() return redirect(to=reverse('buzz:buzz_list')) return render( request=request, template_name='buzz/create.html', context={ 'form': form } ) Here's the code to the model: class BuzzPublishedManager(models.Manager): def get_queryset(self): return ( super().get_queryset().filter(status=Buzz.Status.PUBLISHED) ) class Buzz(models.Model): class Status(models.TextChoices): PUBLISHED = 'PBL', 'Published' DRAFT = 'DFT', 'Draft' title = models.CharField(max_length=250) body = models.TextField() slug = models.SlugField(max_length=250, unique_for_date='publish') publish = models.DateTimeField(default=timezone.now) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) author = models.ForeignKey( to=settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='buzzes' ) status = models.CharField( max_length=3, choices=Status, default=Status.DRAFT ) published = BuzzPublishedManager() objects = models.Manager() class Meta: verbose_name_plural = 'Buzzes' ordering = ['-publish'] indexes = [ models.Index(fields=['-publish']) ] def __str__(self): return self.title The objects in the model was not there before.

Django Allauth's Google Login Redirect and Page Design
Currently, on the login page, I have a button: <div class="d-grid gap-2"> <a href="{% provider_login_url 'google' %}" class="btn btn-danger"> <i class="fab fa-google"></i> Sign in with Google </a> </div> This redirects to accounts/google/login/, and that page allows for redirection to Google authentication. I have two problems: I don't know if these two steps are necessary and I don't see the value of having the extra step accounts/google/login/. I don't know how to replace the standard layout of the accounts/google/login/ page (in case it is really needed). -
Access request session data of DetailView in CreateView in django
I am writing a library management system in Django. There are two views that I am having a bit of a struggle. The BookDetailsView lists the details of a Book such as title, price, etc. class BookDetailsView(LoginRequiredMixin, DetailView): model = Book template_name = 'book_detail.html' def get(self, request, *args, **kwargs): response = super().get(request, *args, **kwargs) request.session['book_pk'] = kwargs['pk'] return response # used to mark book as read or unread def post(self, request, *args, **kwargs): if 'is_read' in request.POST: book = Book.objects.get(pk=kwargs['pk']) book.is_read = True book.save() return HttpResponseRedirect(self.request.path_info) In the BookBorrowView, I display a form where the reader can borrow a book. Two fields are preset (borrowers and book), and I don't want the user to be able to change them. At the moment, the user can select among many options. class BookBorrowView(LoginRequiredMixin, CreateView): model = BookBorrowTransaction template_name = 'book_borrow.html' fields = ['book', 'borrowers', 'date_borrowed', 'to_return', ] success_url = reverse_lazy('home') def get_initial(self): initial = super(BookBorrowView, self).get_initial() initial['borrowers'] = get_object_or_404(CustomUser, email=self.request.user.email) initial['book'] = get_object_or_404(Book, title=Book.objects.get(pk=self.request.session['book_pk']).title) # need the book id here print(self.request.GET) print(self.request.POST) print(self.request.session['book_pk']) return initial The following is a screenshot of the form displayed by the BookBorrowView.

How to configure Nginx to serve Django and a Wordpress site on a specific route?
Good day good people of SO! I have a Django app on a Hetzner server and a Wordpress site on a Hostinger server. I want to configure Nginx on my Hetzner server to serve the Django app and when it requests the /route-name route, it serves a Wordpress site from the Hostinger server. I've already allowed the IP address of my Hetzner server to access the Wordpress site. Hetzner server is running Nginx and Hostinger is running Apache2 if that's relevant. I know there are quite a few questions and answers regarding configuring Nginx to serve Django and Wordpress but I've been scouring this forum and the Internet for several hours now with no solution found for my problem. I suspect it may have to do with my Nginx config, but after trying out several configurations accepted on here and elsewhere, I can't seem to make it work. This is what I currently have for my Nginx config: server { location = /favicon.ico { access_log off; log_not_found off; } location /static/ { alias /var/www/example.com/static/; } location /media/ { alias /var/www/example.com/media/; } # Reverse proxy for /freebies location /route-name/ { proxy_pass http://<IP-ADDRESS OF HOSTINGER SERVER>/; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; … -

How to create a Django custom field with different representations in admin, database, and Python code?
I want to create a custom model field in Django that can store values in bytes in the database but allows users to interact with it in gigabytes (GB) in the Django admin interface. The goal is for the field to handle all necessary conversions seamlessly. Specifically, the field should accept input in GB when adding or editing a record in the admin, convert it to bytes before saving it to the database, and then retrieve it in bytes for use in Python code. I’ve started working on this by overriding methods like to_python, get_prep_value, from_db_value, and formfield, but I’m not entirely sure how to structure these methods to ensure the field behaves as intended. Here is what I already have: class GigabyteField(models.BigIntegerField): def to_python(self, value): if value is None: return value try: return int(value) except (TypeError, ValueError): raise ValueError(f"Invalid value for GigabyteField: {value}") def get_prep_value(self, value): if value is None: return None return int(value * (1024**3)) def from_db_value(self, value, *args): if value is None: return value return int(value / (1024**3)) -
linux ssh key is available to wsl2 django launched by Windows PyCharm
I am working in a development environment for my Django application where I have PyCharm installed on windows, and I launch django in wsl2. This has been working for me flawlessly for a while now. However just now I have a new need to have an ssh key for 3rd party command line tool my application invokes. I created the key in linux and I can execute the command successfully in a linux terminal, however when my django application runs the command fails with the same error it failed with prior to creating my ssh key. At one point I was 100% confident I had found a workaround of starting ssh-agent and then adding an environment variable to my run configuration to set SSH_AUTH_SOCK to the value of SSH_AUTH_SOCK from my terminal, however over the course of trying to find an actual acceptable solution, I can no longer reproduce this, so I'm unsure if that ever even worked or it worked for another reason that I was not aware of.

hi all I’m trying using ModelSelect2Widget I set redis server which I test and it works. then I set the following project: models.py class Doctor(models.Model): user=models.OneToOneField(User,on_delete=models.CASCADE) status=models.BooleanField(default=True) def __str__(self): return "{} ({})".format(self.user.first_name,self.department) class Patient(models.Model): user=models.OneToOneField(User,on_delete=models.CASCADE) assignedDoctorId = models.ForeignKey(Doctor, on_delete=models.CASCADE,related_name='doctor_assigned') admitDate=models.DateField(auto_now=True) status=models.BooleanField(default=False) def __str__(self): return self.user.first_name form.py class BaseAutocompleteSelect(s2forms.ModelSelect2Widget): class Media: js = ("admin/js/vendor/jquery/jquery.min.js",) def __init__(self, **kwargs): super().__init__(kwargs) self.attrs = {"style": "width: 300px"} def build_attrs(self, base_attrs, extra_attrs=None): base_attrs = super().build_attrs(base_attrs, extra_attrs) base_attrs.update( {"data-minimum-input-length": 10, "data-placeholder": self.empty_label} ) return base_attrs class DoctorAutocompleteWidget(BaseAutocompleteSelect): empty_label = "-- select doctor --" search_fields = ("username__icontains",) queryset=models.Doctor.objects.all().filter(status=True).order_by("id") class PatientForm(forms.ModelForm): assignedDoctorId=forms.ModelChoiceField(queryset=models.Doctor.objects.all().filter(status=True), widget=DoctorAutocompleteWidget) but results is an empty list enter image description here while using assignedDoctorId=forms.ModelChoiceField(queryset=models.Doctor.objects.all().filter(status=True),empty_label="Name and Department") it show me list but I would like use select2 in order to user redis and the search bar I would like create select and multiselect menu with searchbar to change list value: in the future I would like the same with table list and change a dropdown menu option if user insert a string in an input module or select an option from one other dropdown menu -
I got 'IncompleteSignature' issue in Aliexpress open platform
I am working over Django using python. I am working on the official SDK for python of Aliexpress. I am trying to get the ACCESS TOKEN from Aliexpress. I got 'IncompleteSignature' issue which means 'The request signature does not conform to platform standards as the part of the response body. Here is full results : {'error_response': {'type': 'ISV', 'code': 'IncompleteSignature', 'msg': 'The request signature does not conform to platform standards', 'request_id': '2141154c17373626146733360'}} My code is very simple because I referred the sample code of their site. (https://openservice.aliexpress.com/doc/api.htm#/api?cid=3&path=/auth/token/create&methodType=GET/POST) Here is my code: def callback_handler(request): code = request.GET.get('code') url = "https://api-sg.aliexpress.com/sync" appkey = "123456" appSecret = "1234567890XXXX" client = iop.IopClient( url, appkey, appSecret, ) request = iop.IopRequest('/auth/token/create') request.add_api_param('code', code) response = client.execute(request) response_type = response.type response_body = response.body print(response_type) print(response_body) return HttpResponse(f"Response type: {response_type}, Response body: {response_body}") I posted the question to the Aliexpress console but they replied with a very vague answer and a Java script reference code. I was shocked. It was not even python. And this advice can be only implemented if I modified their SDK itself. I am not sure if the python SDK is of practical working quality. Since I have been spending too much time and … -
How to Include a Message Field in Structlog Logs and Best Practices for ElasticSearch Integration
I'm working on a Django project where logging is critical, and I'm using structlog to format and manage logs. The plan is to send these logs to ElasticSearch. However, I've encountered an issue: the logs are missing the "message" field, even though I explicitly pass a message in the logger call. Here’s the log output I currently get: { "code": 200, "request": "POST /api/push-notifications/subscribe/", "event": "request_finished", "ip": "127.0.0.1", "request_id": "d0edd77d-d68b-49d8-9d0d-87ee6ff723bf", "user_id": "98c78a2d-57f1-4caa-8b2a-8f5c4e295f95", "timestamp": "2025-01-21T10:40:43.233334Z", "logger": "django_structlog.middlewares.request", "level": "info" } What I want is to include the "message" field, for example: { "code": 200, "request": "POST /api/push-notifications/subscribe/", "event": "request_finished", "ip": "127.0.0.1", "request_id": "d0edd77d-d68b-49d8-9d0d-87ee6ff723bf", "user_id": "98c78a2d-57f1-4caa-8b2a-8f5c4e295f95", "timestamp": "2025-01-21T10:40:43.233334Z", "logger": "django_structlog.middlewares.request", "level": "info", "message": "push notification subscribed successfully" } Here’s my current setup: settings.py Logger Configuration LOGGING = { 'version': 1, 'disable_existing_loggers': False, "formatters": { "json_formatter": { "()": structlog.stdlib.ProcessorFormatter, "processor": structlog.processors.JSONRenderer(), }, "plain_console": { "()": structlog.stdlib.ProcessorFormatter, "processor": structlog.dev.ConsoleRenderer(), }, "key_value": { "()": structlog.stdlib.ProcessorFormatter, "processor": structlog.processors.KeyValueRenderer(key_order=['timestamp', 'level', 'event', 'message']), }, }, 'handlers': { "console": { "class": "logging.StreamHandler", "formatter": "plain_console", }, "json_file": { "level": "INFO", "class": "logging.handlers.RotatingFileHandler", "filename": "logs/ft_json.log", "formatter": "json_formatter", "maxBytes": 1024 * 1024 * 5, "backupCount": 3, }, "flat_line_file": { "level": "INFO", "class": "logging.handlers.RotatingFileHandler", "filename": "logs/flat_line.log", "formatter": "key_value", "maxBytes": 1024 * 1024 * …
