Django Admin: How to hide nested inline until parent is saved?
I have a nested inline setup in Django Admin where I want to hide a child inline until its parent is saved. Here's a simplified version of my models: class Parent(models.Model): name = models.CharField(max_length=255) class Child(models.Model): parent = models.ForeignKey(Parent, on_delete=models.CASCADE) name = models.CharField(max_length=255) class GrandChild(models.Model): child = models.ForeignKey(Child, on_delete=models.CASCADE) name = models.CharField(max_length=255) And here's my admin setup: class GrandChildInline(NestedTabularInline): model = GrandChild extra = 0 def get_formset(self, request, obj=None, **kwargs): formset = super().get_formset(request, obj, **kwargs) return formset class ChildInline(NestedTabularInline): model = Child extra = 0 inlines = [GrandChildInline] class ParentAdmin(NestedModelAdmin): inlines = [ChildInline] admin.site.register(Parent, ParentAdmin) Current Behavior When editing a Parent, I can add Children The GrandChild inline is visible immediately when adding a new Child I want the GrandChild inline to only appear after the Child is saved Desired Behavior GrandChild inline should be hidden when adding a new Child GrandChild inline should only appear after the Child is saved GrandChild inline should be visible when editing an existing Child What I've Tried Using the template property to return an empty string Using has_add_permission and get_queryset Checking for parent instance existence None of these approaches fully work - either the inline is always visible or always hidden.

Django fails to correctly link viewable documents stored in a Django model
So I currently have a Django model which correctly references everything passed to my template, except for the link to the document I have uploaded. The model has been correctly registered in admin.py. Here is is MRE: #investors/models.py from django.db import models class FinancialStatements(models.Model): financials_upload = models.FileField(upload_to='documents/financials/') class Meta: verbose_name_plural = "Financial Statements" #investors/views.py from .models import FinancialStatements def investor_relations(request): financials_queryset = FinancialStatements.objects.all() context = { 'financials_queryset' : financials_queryset, } return render(request, 'investors.html', context) #settings.py MEDIA_URL = '/assets/' MEDIA_ROOT = BASE_DIR / 'assets' #investors/templates/investors.html {% for financials in financials_queryset %} <a href="{{financials.financials_upload.url}}">Financial Statement</a> {% endfor %} Upon accessing the uploaded file from the model, the URL is http://127.0.0.1:8000/assets/documents/financials/<filename>.pdf which is the directory I want to specify, and so is correct. However, Django is continuing to fail to access the URL from {{financials.financials_upload.url}} when looping through the financials_queryset quertset My file directory is set up in the following fashion: <ROOT>/assets/documents/financials/** Whenever I hover over the <a> tag, the message in the bottom of the left corner of the browser fails to return the URL of the document to be viewed. It simply returns http://127.0.0.1:8000/investors Despite this, I do fail to see how cannot work this one out, despite correctly point it … -
Settings.py cannot find psycopg2... squlite3 and postgresql problem... no such table: auth_user
I'm trying to deploy a simple app (learning log from Python Crash Course) to heroku. The app runs but upon login, I get a 500 error, and in debug=true the error is: no such table: auth_user. I realise this has something to do with squlite3 and Postgresql, but when I try to build the code in settings: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': BASE_DIR / 'db.sqlite3', } } the error message is ImportError: DLL load failed while importing _psycopg: The specified module could not be found. I have attempted to install and import psycopg2, and it appears to be in requirements.txt. But I think the paths are not aligning, since psycopg2 is in a python pathway, and setting.py is looking in my project environment. I'm very confused! Please help! -
Why am I getting a 403 Forbidden error when making a POST request to the login API in Vue.js?
I'm working on a Vue.js application where users can log in through an API using the axios library. However, when I send a POST request to the API endpoint, I'm getting a 403 Forbidden response. Here's the Vue.js code for the login request: const response = await axios.post( 'https://apibackup.example.com/api/login/', { username: email.value, password: password.value }, { headers: { 'Content-Type': 'application/json' }, withCredentials: true, withXSRFToken: true } ) And here's the login view from the Django backend: def login_view(request): if request.method == 'POST': try: data = json.loads(request.body) form = LoginForm(data) if form.is_valid(): username = form.cleaned_data['username'] password = form.cleaned_data['password'] user = authenticate(request, username=username, password=password) if user is not None: login(request, user) # Logic for handling user types here... else: return JsonResponse({'status': 'error', 'message': 'Invalid username or password'}, status=401) else: return JsonResponse({'status': 'error', 'errors': form.errors}, status=400) except json.JSONDecodeError: return JsonResponse({'status': 'error', 'message': 'Invalid JSON data'}, status=400) Here are the relevant settings from the Django settings.py: CORS_ALLOW_CREDENTIALS = True CORS_ALLOWED_ORIGINS = [ 'https://example.com', 'http://localhost:5173', # other domains... ] CSRF_TRUSTED_ORIGINS = [ 'https://example.com', 'http://localhost:5173', # other domains... ] CSRF_COOKIE_SAMESITE = 'None' CSRF_COOKIE_SECURE = True CSRF_COOKIE_DOMAIN = 'example.com' Issue: When I try to log in, I get the following error in the browser console: POST https://apibackup.example.com/api/login/ … -

How to Add a Python Interpreter to a Web Application?
I am currently working on a Learning Management System (LMS) web app, and one of the features I need to implement is a web-based Integrated Development Environment (IDE) where users can write, execute, and test Python code directly in the browser. What I am looking for: Guidance on integrating a Python interpreter into the web app. Best practices for securely running user-submitted Python code to prevent malicious activities. Recommendations for tools, libraries, or APIs that can help execute Python code. How to handle input/output in the IDE and display results to the user in real-time. Key considerations: The web app is built using Django and react. Code execution should be sandboxed for security. The IDE should be able to handle basic Python scripts and display outputs/errors to users and suggestions too. -
Does anyone have any ideas on how to make django multilingual more elegant and easier to maintain? [closed]
I had to realize that implementing multilingualism in Django turns out to be an absolute pain. I have seen the following variants, which are absolutely subterranean: Language via Excel. As I said, the message files. This also includes Django-Rosetta, which is a kind of management interface for the message files. And last but not least json files. Unfortunately, that doesn't make it any better for me. Does anyone have any ideas on how to make this more elegant and easier to maintain? Is there an extension that compares the languages like ResXManager Extension in Visual Studio? Thanks in advance. -

WebSocket (python server, javascript/rxjs client) missing messages
Introduction I'm trying to provide as much info up front, so if I've missed something, please let me know. Motivation: server does the work (asyncio with multi-processing), client just requests and presents data. WebSockets (herein WS) used primarily to minimize latency of requests and replies (connection protocols done up front, and TLS connection done once). WS uses TCP, which has produced sufficiently transparent transactions...no need for UDP or anything for greater speed. Setup WS server: Python/Daphne/Django Channels (updated) WS client: Javascript/Angular/Rxjs (updated) Both running on localhost (no physical throughput contention, ) Applications Client: Angular, primarily requesting and formatting data for presentation Server 1: Django channels async JSON consumer (asyncio framework...maybe important later). Server 2: Python using WebSockets pypi asyncio package (currently legacy...will address later...confirmed not the issue). Server 1 instance connects to server 2 TLS WS connection. Problem I implemented the servers a few years ago. Long story short: I was seeing some aspects of latency in places I didn't expect when using await with the Django ORM. Short answer? I just switched the DB connections from database_sync_to_async to wrapping the calls in asyncio.to_thread. The concurrency experienced has improved by a factor of 10 without a doubt, as I was … -

Deployed Django project on vercel can't see tables on the database
I have deployed a django project through vercel and my log in and sign up authentication can't seem to go through.

Django Admin Action Function Failing - emailing multiple selected users (if "apply" in request.POST)
My implementation uses a CustomUser model. I'm creating a Django admin action that allows me to compose and send emails to multiple users. Everything on the website behaves as though it's working. After I hit the Send Email button, I'm redirected back to the Admin but I see no console output indicating an email was sent and self.message_user is never called and sent to the Admin. Email Backend Password Reset works with reset link sent to the console, so email backend is working. EMAIL_BACKEND = "django.core.mail.backends.console.EmailBackend" admin.py if "apply" in request.POST: <-- This line never fires! class CustomUserAdmin(ExportMixin, UserAdmin): @admin.action(description="Email selected users") def send_email_action(self, request, queryset): print(request.POST) print(request.POST.getlist("apply")) input("HALT") if "apply" in request.POST: print("apply") form = EmailForm(request.POST) if form.is_valid(): print("form valid") subject = form.cleaned_data["subject"] message = form.cleaned_data["message"] recipients = [user.email for user in queryset] send_mail(subject, message, "your_email@example.com", recipients) self.message_user(request, f"{len(recipients)} emails were sent.") return HttpResponseRedirect(request.get_full_path()) else: print("no apply") form = EmailForm() return render(request, "email/admin_send.html", {"form": form}) forms.py Works as expected. class EmailForm(forms.Form): subject = forms.CharField(max_length=256) message = forms.CharField(widget=forms.Textarea) admin_send.html Either: The send_email_action function is getting called after I hit the Send Email button but the form isn't sending back the "apply" data, so this is failing: if "apply in request.POST: … -

Django Diagnosis Data Not Appearing in Admin After Endpoint Execution
I am working on a Django project where I process mock patient data and save it to a DiagnosisResult model in the database (SQLite). The goal is for this data to appear in the Django admin interface, but after calling the endpoint, the data doesn't appear in the database or admin. By "mock," I mean fictional data (not testing framework mocks), which I pre-generated to avoid using real patient data.

I tried changing the code to check if it displays date when dt_created==dt_updated and it actually didn't display the edited time for all comments, including the comments that were edited. I also tried using comment.edited and it also didn't display edited time for all comments. What is wrong with my code? -
How to call and process Confirmation popup from a service function without interrupting the transaction
In my Django project, the business logic is placed in the service layer. Views only perform the function of working with templates. I have a basic template with a form and select type fields on it. When any field is changed, the script sends an AJAX request to views. views accepts this request and passes the data to a service function that uses it to write to the DB. template -> views -> service -> model Now I need to make a function to call the Confirmation popup from service to confirm the data change, receive a response from the window and process it. I already have a modal window and a script that calls it when response.confirmation_dialog. I need a mechanism for calling this window from the service without interrupting the transaction. One of the implementation options was to send a response to template with a confirmation modal call. Clicking the confirm-button on it would again send an AJAX request to views with confirmation information. Then this information would be sent back to the service, which checked whether the confirmation was passed or not. However, even with one confirmation, it looks bad, and the service may need several checks … -
