Django UpdateView Creates New Object Instead of Updating the Existing One
I'm having an issue with my Django update view. Although I see the correct data on the update form (i.e. the GET request pre-fills the form with the existing article’s content), when I submit the form the original article isn’t updated—instead, a new article is created with a new uid, and the original still remains with its original uid. I’ve verified that: My update view initializes the ModelForm with the existing instance using the instance parameter. My URL configuration includes the primary key (uid) in the URL. Below is a simplified version of my code. views.py: from django.shortcuts import render, get_object_or_404, redirect from .models import Article from .forms import ArticleForm def ArticleUpdate(request, pk): # Fetch the existing article using the uid passed via URL article = get_object_or_404(Article, uid=pk) if request.method == 'POST': # IMPORTANT: The form is instantiated with the existing instance! form = ArticleForm(request.POST, request.FILES, instance=article) if form.is_valid(): form.save() # Expect this to update, not create a new article return redirect('article-read', pk=article.uid) else: print("Form errors:", form.errors) else: form = ArticleForm(instance=article) context = {'form': form} return render(request, 'blog/article_form.html', context) urls.py: from django.urls import path from blog import views urlpatterns = [ path('articles/create/', views.ArticleCreate, name='article-create'), path('articles/<str:pk>/', views.ArticleRead, name='article-read'), path('articles/<str:pk>/update/', views.ArticleUpdate, name='article-update'), … -

django application with firebase authentication
LLMs are failing me on this seemingly simple task, so I'm seeking community advise. I have a django application, which works fine. Both when I develop locally, and in production at https://my.domain Now, I need to add one more page to the application, that will be behind firebase authentication flow. The reason being I've already gotten a pool of users from my mobile application (unrelated to https://my.domain). I want to give access to the same users to their data they generated through my mobile app. My understanding was if they used same firebase ID (either google id, or apple id) as in app, it should be doable. Problems start pretty much off the bat. Here's what I did I've created firebase app and generated config data in firebaseConfig. Since I'm developing locally, I've added localhost to the list of Authorized domains list in firebase console. Google, Apple, Email logins are enabled. As they always were because of my mobile application. Service account credentials file is downloaded, stored, pointed at in django. I ran local server through python manage.py runserver I added login button in my login template. When I hit login (through google popup), list of my google accounts open. … -
Google OAuth2 Signup in Django: 'Bad Request' Error on First Signup Attempt
I'm working on integrating Google OAuth2 login/signup with Django, but I'm encountering an issue during the first signup attempt. The Flow: New User Registration using Google. The user clicks on the "Login with Google" button. The user is redirected to the Google OAuth2 consent screen and logs in. After successful Signup, Google redirects back to my app with a Bad Request - "POST /api/v1/auth/google/ HTTP/1.1" 400 Bad Request : this only happens first time the user tries to sign up, It returns a "Bad Request" error. The issue only occurs during the first signup, even though the user data is added to the database. If I try to login back with the same account using google now then i will be able to Login Successfully. Relevant Code : backend/api/urls.py : path('auth/google/', GoogleLogin.as_view(), name='google_login') backend/api/views.py : from django.conf import settings from django.http import HttpResponseRedirect from allauth.socialaccount.providers.google.views import GoogleOAuth2Adapter from allauth.socialaccount.providers.oauth2.client import OAuth2Client from dj_rest_auth.registration.views import SocialLoginView class GoogleLogin(SocialLoginView): adapter_class = GoogleOAuth2Adapter client_class = OAuth2Client callback_uri = settings.REDIRECT_URI def get(self, request): return HttpResponseRedirect(redirect_to=settings.GOOGLE_AUTH_URL) backend/api/adapter.py: from allauth.socialaccount.adapter import DefaultSocialAccountAdapter from api.models import User class CustomSocialAdapter(DefaultSocialAccountAdapter): def pre_social_login(self, request, sociallogin): # Ignore existing social accounts, just do this stuff for new ones if sociallogin.is_existing: … -
Buttons On Click Functioning with same ID different and different attributes
I have an HTML webpage with a sample of buttons as shown part of a Django Application that fills in the name and town after inserting the values: {% for person in page_obj %} <button id="NotifyBtn" name="person.FName" town="person.LName">Press Me</button> {% endfor %} <button id="NotifyBtn" name="Billy" town="Bob">Press Me</button> <button id="NotifyBtn" name="Timmy" town="Tawin">Press Me</button> <button id="NotifyBtn" name="Milly" town="House">Press Me</button> Then I have a JS that does the following: document.getElementById("NotifyBtn").addEventListener("click", function(){ var name = this.getAttribute("name"); var town = this.getAttribute("town"); fetch("{% url 'alert_via_JSON_Response' %}", { method: "POST", headers: { "X-CSRFToken": "{{ csrf_token }}", "Content-Type": "application/json" }, body: JSON.stringify({ message: "Hi there: " + `${name} born in ${town}` }) }).then(response => response.json()) .then(data => alert(data.status)); }); In my Django application I have the following: def alert_via_JSON_Response(request): if request.method == 'POST': data = json.loads(request.body) message = data.get('message', "Error in sending email") return JsonResponse({"status": f"{message}"}) return JsonResponse({"status": f"No Message"}) Right now, when I click on the webpage, only one button works and sends a JSON response to the webpage, it doesn't work if I press another button after pressing the first button. Is there a way to press each button when needed and display the JSON response for each button? -
Dockerized Django app - `gunicorn: command not found` on AWS deployment
I have a Dockerized Django app that is deployed on AWS - after some recent updates to the Debian and PostgreSQL images that I'm using in the Dockerfile, the app is suddenly failing to start running successfully when it hits AWS due to an issue with gunicorn - pyenv: gunicorn: command not found This problem did not occur previously and, if I simply deploy a build based on the previous git commit (prior to making these updates), the app deploys and runs just fine. Furthermore, when I run the app locally via docker-compose up and bash into the container, I can run gunicorn commands no problem, so I'm not quite sure what the issue is - gunicorn is included in the requirements.txt file. Maybe I'll need to provide more info, but for starters, here is the current setup of the Dockerfile and requirements.txt files - I'll note the changes that have been made below them - Dockerfile FROM andrejreznik/python-gdal:py3.11.10-gdal3.6.2 ENV PYTHONUNBUFFERED 1 RUN pip install --upgrade pip RUN apt-get update RUN apt-get upgrade -y RUN apt-get install postgresql-15 postgresql-server-dev-15 -y RUN mkdir /code WORKDIR /code COPY requirements.txt /code/ RUN pip install -r requirements.txt COPY . /code/ ARG ALLOWED_HOSTS ARG AWS_ACCESS_KEY_ID … -
Django custom filter working in dev but not in prod
I created a custom template filter in django at myapp/templatetags/custom_filters.py. @register.filter(name='indian_number_format') def indian_number_format(value): """ Format the number in Indian style using the locale module (e.g., 1,00,00,000). """ if not isinstance(value, (int, float, Decimal)): print('Not a number', type(value)) return value try: # Set the locale to Indian (Hindi) locale.setlocale(locale.LC_NUMERIC, 'hi_IN') # Format the number using locale formatting formatted_value = locale.format_string("%d", value, grouping=True) return formatted_value except locale.Error: # Fallback in case the locale is not available on the system return value Using it in template like this {% extends "base.html" %} {% load custom_filters %} <p>{{number|indian_number_format}}</p> For example, if the number is 123456, the output should be 1,23,456 and this works fine in dev but the commas do not appear in prod which I have hosted on AWS. Any insight on what might be causing this issue would be helpful. Thanks. -

django-x509 library - any way to use certificate authentication only on several pages of application and continue with password for others?
After searcxhing and investigating various X509 libs for django I found this https://github.com/openwisp/django-x509 IMHO looks the best - even CA and certificate generation are present in admin UI. However, thinking now, how to use it the best way in my case - please, see short description and image below Data entry to the site should be done using two ways - automated POST from standalone application using cartificate authentication, and regular https for data watch and manual entry (sorry 4 typo in the image). It's important to remember, that application is standalone - no {% csrf_token %} in it indeed. So, general advice is needed. IMHO, the best way is to use cert autentication on the automated POST URL only, with password for other pages, but how? If mentioned above is not possible - needed to make two apps with sharing data model in common database to x509 app. Found 1 reply for sharing question with -1 rep here, not sure, that workable - advice is welcome. In addition. may happen user management problems in 2 apps etc, I think, that the first method is better. BTW, if the lib authors are here - sample of integraion into existing site … -

Making changes to database structure in django
Hi I am looking to get some guidance on how to properly make changes to the models in django. Currently I'm working on an app where I have previously defined models and have uploaded data for these models. However I would like to make some changes to the schema of the database and edit and add/delete some columns of the tables. I am running into some issues with this where django will not allow me to make migrations or migrate after certain changes. If anyone could give me some tips on why this is happening and best practices to follow when I am making changes like this it would be very helpful. Also currently I am using a sqlite3 db. I have tried to delete migrations and the database but had no success and I would also like a solution that is more practical if I wanted to make changes like this when the app in in production -

CORS headers not being added in django
Preface, I am aware of django-cors-headers not work I am getting the following error: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at ... (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 301. Here are the important parts of my settings.py. INSTALLED_APPS = [ ... corsheaders ... ] corsheaders is the last entry in INSTALLED_APPS MIDDLEWARE is: MIDDLEWARE = [ 'corsheaders.middleware.CorsMiddleware', 'django.middleware.security.SecurityMiddleware', 'whitenoise.middleware.WhiteNoiseMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.middleware.common.CommonMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', "allauth.account.middleware.AccountMiddleware", ] So CorsMiddleware is at the top.

How do I fix this? -
