dynamically instantiate database django
In a django web application, when logging in I am saving the name of the database in the session. I need a method to dynamically instantiate the database using this name that is saved in the user session. I dont't want to use "using()" because my aplication is already done, and it would give me a lot of work, neither by configuring multiple databases in your settings (because my databases are being createded dinamically) if there is another way i would like to know. Maybe it's not possible, i understand if it's the case... I tried middlewares, routes, threading, decorators but maybe a think i would have done something wrong. I exhausted my attempts. As far as I could go i get logged in the right database until the second screen of my application, when i am browsing in the application the 3 screen i pass the database goes back to default. middleware: import re from django.utils.deprecation import MiddlewareMixin from django.db import connections from .thread import set_banco_academia class DatabaseMiddleware(MiddlewareMixin): def process_request(self, request): """ Middleware que define dinamicamente o banco de dados a ser usado com base na sessão do usuário e adiciona a conexão ao Django.

Django form doesn`t appear in page
I want to add posts in adding system from user profile page (without creating another page to adding).

Is there any way to take add tooltip to the select2 li items?
i work on a django project where i also use bootstrap and select2. I have this HTML: {% load i18n %} <select id="{{ select_id }}" name="{{ select_name }}" class="form-control"> <option value="">{% trans 'Alege TVA' %}</option> {% for vat_rate in vat_rates %} {{ vat_rate.text_tooltip }} <option value="{{ vat_rate.actual_value }}" title="{{ vat_rate.text_tooltip }}"> {{ vat_rate.full_name }} </option> {% endfor %} </select> and this in JavaScript: $('#id_vat_value').select2({ placeholder: gettext("Alege TVA"), escapeMarkup: function (m) { return m; }, matcher: function (params, data) { return TrimSpacesSelect2(params, data); }, }) is there any way to add the tooltip to the select2 li items? I tried to add it in select2:open, but i don't think is really good, right now it is showing the tooltip but i don't know if it's the best choice. .on('select2:open', function () { setTimeout(function () { $('.select2-results__option').each(function () { var $option = $(this); var optionId = $option.attr('id'); var originalOption = $('#id_vat_value option').filter(function () { return $(this).val() === optionId.split('-').pop(); }); var tooltip = originalOption.attr('data-original-title'); if (tooltip) { $option.attr('title', tooltip); $option.attr('data-toggle', 'tooltip'); } }); $('[data-toggle="tooltip"]').tooltip({ delay: {show: 500, hide: 0}, trigger: "hover" }); }, 100); }); -
Where to deploy Next.js & Django
I have created a project that uses Next.js on the frontend and Django on the backend, the web app uses JWT for requests. Now I want to deploy the project and want to ask where I should do it? Do I have to use two different services or can I use one service for both? I have done the Next.js getting started tutorial where you get to create a dashboard app and deploy it using Vercel, that was very simple, can I do the same with this project? Also, I'd like to add that the database used currently while I'm developing is the default SQLite but I do want to switch to a "real" database like PostgreSQL, for example, later when launching. -
Django Celery: Kombu connection refused error

How to secure JWT tokens with a DRF backend supporting both mobile and SPA clients?
I am developing an application that uses the Django REST Framework to provide a REST API. I intend to protect it using token authentication, with the help of simple_jwt. Example API overview: /auth/login/: Supports POST, requires valid username and password, returns a JWT access and refresh /auth/refresh/: Supports POST, requires a valid refresh token, returns new access and refresh tokens /protected/endpoint/: Requires a valid access token From reading on CSRF I have gathered: CSRF is only needed if cookies are involved, so only use for the SPA client To persist the JWT token: SPA: Persist in an httpOnly cookie with secure=true and same-origin set App: Persist in however the app persistent state works So far so good, however, this would mean that my REST API needs to both require CSRF tokens for requests coming from the SPA and not require/ignore CSRF tokens for requests coming from mobile app clients. Since this is logically impossible I was first thinking of implementing 2 separate APIs. I.e.: /spa/auth/..., /spa/protected/...: For SPA clients, where all endpoints require a CSRF token /mobile/auth/..., /mobile/protected/...: For mobile clients, where all endpoints are CSRF exempt. But doing this just means that my CSRF protection is useless, since a … -
How to fetch real-time google cloud run job logs?
I am building a CI/CD kind of tool which is actually a web app. The stack is django-rest-framework on the backend and React (Vite) on the frontend. Currently the pipeline running and the actions from the stages that are running are all working, the jobs are being created, ran, deleted and it all works fine. This is all happening through the Google Cloud Run Jobs. For the app to make sense, I need to be able to get real-time logs from that specific job while it is running. Currently I have a crude temporary implementation where I am using the Google Cloud Logging API with filters to periodically get the logs for that job. This is the mentioned crude implementation: from google.cloud import logging_v2 from apps.docker_app.utils.google_credentials import get_google_credentials def _stream_job_logs(logging_client, log_filter): seen_entries = set() while True: entries = logging_client.list_entries(filter_=log_filter) for entry in entries: if entry.insert_id not in seen_entries: seen_entries.add(entry.insert_id) yield entry time.sleep(1) class GoogleLogsClient: def __init__(self): storage_credentials = get_google_credentials() self.client = logging_v2.Client(credentials=storage_credentials) def stream_job_logs(self, log_filter): for entry in _stream_job_logs( logging_client=self.client, log_filter=log_filter ): if "All stages completed successfully" in entry.payload: break timestamp = entry.timestamp.isoformat() print("* {}: {}".format(timestamp, entry.payload)) While this does work, I am limited to 60 read requests to the … -
Django Admin Not Displaying `creation_date` Field Despite Being in `list_display`
I have a Django project where I'm working on an e-commerce application. I'm using SQLite as my database, and I'm trying to add a creation_date field to my VendorProduct model so that it records when a product was created. What I Did I added the creation_date field to my VendorProduct model like this: models.py (VendorProduct Model) from django.db import models from django.utils.timezone import now from userauths.models import CustomUser class VendorProduct(models.Model): user = models.ForeignKey(CustomUser, on_delete=models.SET_NULL, null=True, blank=True) creation_date = models.DateTimeField(auto_now_add=True, blank=True, null=True) def __str__(self): return self.title Migrations I ran the following commands to apply the migration: python manage.py makemigrations vendorpannel python manage.py migrate vendorpannel Then, I verified that the creation_date column exists in my database using: from django.db import connection with connection.cursor() as cursor: cursor.execute("PRAGMA table_info(vendorpannel_vendorproduct);") columns = cursor.fetchall() for column in columns: print(column) The output confirms that creation_date exists in my database: (7, 'creation_date', 'datetime', 0, None, 0) Admin Panel Configuration I updated my admin panel to display creation_date: admin.py from django.contrib import admin from .models import VendorProduct class VendorProductAdmin(admin.ModelAdmin): list_display = ('creation_date') readonly_fields = ('creation_date',) admin.site.register(VendorProduct, VendorProductAdmin) Problem: creation_date Not Showing in Django Admin Even after making these changes and applying migrations, the creation_date field is not appearing in … -

Why does AWS ALB Health Checks Fail with Correct Security Group (EC2, Docker, nginx-proxy, ACM)?
I'm having trouble getting my AWS Application Load Balancer (ALB) health checks to pass when my EC2 instance's security group is configured correctly. The site works when I open port 443 to the world (0.0.0.0/0), but fails when I restrict it to the ALB's security group, even with Source/Destination Check disabled. EC2 Instance Configuration: Docker Compose runs nginx-proxy, acme-companion, Django (web), and other services. nginx-proxy is mapped to ports 80 and 443 on the host. VIRTUAL_HOST is set to my domain. VIRTUAL_PORT is correctly set to 8000 EC2 Instance Security Group: Correct Configuration (Failing): Allows inbound HTTPS (port 443) only from the ALB's security group (e.g., sg-xxxxxxxx). Temporary Workaround (Working): Allows inbound HTTPS (port 443) from 0.0.0.0/0. Source/Destination Check is disabled on the EC2 instance. Request Flow: Client Request -> Route 53 -> Application Load Balancer (HTTPS:443) -> AWS WAF -> ALB Target Group (HTTPS:443) -> EC2 Instance (port 443, nginx-proxy) -> Docker Container (port 8000, Django) ALB Configuration: Listener on port 80 (HTTP) redirects to HTTPS (443). Listener on port 443 (HTTPS) forwards to the target group. ALB Security Group: Allows inbound on ports 80 and 443 from 0.0.0.0/0.

Django Formset Nested Structure Not Posting Correctly for Dynamic Fields
I’m working on a Django nested formset where users can: Add multiple colors to a product. For each color, add multiple sizes dynamically using JavaScript. Each size should have its own size_name, stock, and price_increment field. Issue When submitting the form, Django is incorrectly grouping multiple size field values into lists instead of treating them as separate entries. Expected Django POST Data (Correct Structure) sizes-0-0-size_name = "Small" sizes-0-0-stock = "100" sizes-0-0-price_increment = "50" sizes-0-1-size_name = "Medium" sizes-0-1-stock = "150" sizes-0-1-price_increment = "75" Actual Django POST Data (Incorrect Structure) sizes-0-0-size_name = ["Small", "Medium"] sizes-0-0-stock = ["100", "150"] sizes-0-0-price_increment = ["50", "75"] Instead of separate fields for each size, Django is grouping values into a single list. The sizes-0-TOTAL_FORMS field is appearing twice in the POST request, which might indicate a JavaScript duplication issue. Debugging the Request Data (request.POST) <QueryDict: { 'colors-TOTAL_FORMS': ['1'], 'sizes-0-TOTAL_FORMS': ['1', '1'], # This should be a single value, not duplicated 'sizes-0-0-size_name': ['Small', 'Medium'], 'sizes-0-0-stock': ['100', '150'], 'sizes-0-0-price_increment': ['50', '75'] }> Potential Causes: JavaScript Issue: Dynamic form addition might be incorrectly naming inputs, causing Django to interpret multiple values as a list.

How to implementing pagination for Django 5 admin sidebar filters?
The Problem Django's admin sidebar filters show all options without pagination, which becomes unwieldy when you have hundreds of related objects: By Study • All • Study-001: Genetic markers in mice • Study-002: Effects of caffeine ... • Study-999: Soil microbiome analysis With many options, this makes the UI unusable and harms performance. Our Approach We implemented custom filters with pagination to display only a subset of options at a time: By Study • All • Study-001: Genetic markers in mice • Study-002: Effects of caffeine ... • Study-010: Plant growth factors Page 1 of 100 | Next > Implementation Custom filter class: class StudyListFilter(SimpleListFilter): title = _('By Study') parameter_name = 'study__id__exact' template = 'admin/filter_pagination.html' # Custom template def lookups(self, request, model_admin): # Return minimal data - real items are provided in the template return [('', 'All')] def queryset(self, request, queryset): if self.value(): return queryset.filter(study__id=self.value()) return queryset Modified admin class: @admin.register(Assay) class AssayAdmin(admin.ModelAdmin): list_filter = (StudyListFilter, 'measurement_type') change_list_template = 'admin/study_change_list.html' def changelist_view(self, request, extra_context=None): extra_context = extra_context or {} # Get paginated studies studies = Study.objects.all().order_by('id') paginator = Paginator(studies, 10) page_number = request.GET.get('filter_page', 1) page_obj = paginator.get_page(page_number) # Pass pagination data to template extra_context.update({ 'filter_page_obj': page_obj, 'filter_items': [(s.id, f"{s.accession_code} - … -

How to disable Django Debug Toolbar while rendering a template?
I'm using Django Debug Toolbar in my development environment, and it's been very helpful for debugging. However, I want to disable it when rendering a specific template. Is there a way to conditionally disable the debug toolbar for certain views or templates? Here’s what I’ve tried so far: Using settings.DEBUG: I know that the toolbar is only shown when DEBUG = True in settings.py, but I don't want to disable it for the entire project, just for specific views or templates. Template Context: I also considered passing a context variable to the template to control the toolbar's visibility, but I’m not sure how to integrate this with the toolbar's behavior. Here’s a simplified version of my view: from django.shortcuts import render def my_view(request): context = {'some_data': 'data'} return render(request, 'my_template.html', context) And in my settings.py: DEBUG = True if DEBUG: INSTALLED_APPS += ['debug_toolbar'] MIDDLEWARE += ['debug_toolbar.middleware.DebugToolbarMiddleware'] django_debug_toolbar version is 3.8.1 Is there a way to disable the Django Debug Toolbar specifically for this view or template? -
Django Formset Dynamic Add/Remove Not Working for Colors, Sizes, and Images
Problem Statement I am working on a Django formset where users can dynamically add/remove colors, sizes, and images when adding a product. The structure of my formset is as follows: A product can have multiple colors. Each color can have multiple sizes. Each color can have multiple images. Users should be able to dynamically add/remove colors, sizes, and images using JavaScript. Expected Behavior Clicking "Add Color" should create a new color form with its own size and image sections. Clicking "Add Size" within a color should add a new size only to that specific color. Clicking "Add Image" within a color should add a new image only to that specific color. Clicking "Remove Color" should remove the specific color section. Current Issue Only the "Remove Color" button works. "Add Color", "Add Size", and "Add Image" buttons are not working. No new elements are being appended to the DOM when clicking the buttons. Debugging Attempts ✔ Checked Django Formset Management Forms (they exist). ✔ Verified event listeners are attached using console.log(). ✔ Ensured cloneNode(true) properly copies elements. ✔ Checked for JavaScript errors in the console (no syntax errors).

Is it correct to modify `django.db.connections.databases` dynamically to multiple databases? Or is it better to deploy a separate API per client?
This is my first time developing a multi-tenant SaaS application in Django, in this SaaS each company has its own PostgreSQL database, and these databases are created dynamically when a company registers. I cannot predefine all databases in settings.DATABASES, as companies can register at any time without requiring a server restart. My current solution uses Middleware to detect the company from the subdomain or a JWT token and then modify connections.databases at runtime to configure the connection to the company's database: import redis from django.db import connections from django.core.exceptions import ImproperlyConfigured from django.utils.connection import ConnectionDoesNotExist from rest_framework_simplejwt.authentication import JWTAuthentication from myapp.models import Company # Company model stored in the global database class CompanyDBMiddleware: def __init__(self, get_response): self.get_response = get_response self.jwt_authenticator = JWTAuthentication() self.cache = redis.Redis(host='localhost', port=6379, db=0) def __call__(self, request): company_db = self.get_database_for_company(request) if not company_db: raise ImproperlyConfigured("Could not determine the company's database.") # Register connection only if it does not exist in `connections.databases` if company_db not in connections.databases: connections.databases[company_db] = { 'ENGINE': 'django.db.backends.postgresql', 'NAME': company_db, 'USER': 'postgres', 'PASSWORD': 'your_password', 'HOST': 'localhost', 'PORT': '5432', 'CONN_MAX_AGE': 60, # To avoid opening and closing connections on each request } request.company_db = company_db response = self.get_response(request) # Close connection after the response try: … -
handle auth workflow with django API and react
I have a frontend app written in react I have a backend application which is a django server. On top of that I am working with a 3rd party True Layer (Open Banking API) The first thing I want to implement is the authentication which I did correctly. However, I am trying to write a method to refresh my access_token thanks to the refresh_token given by the TrueLayer API when user first authenticate. The problem is that from what I read online the good practice is to have the refresh_token stored into the HTTP only cookies. So I did something like this def truelayer_callback(request): code = request.GET.get('code') token_data = { "grant_type": "authorization_code", "client_id": settings.TRUELAYER_CLIENT_ID, "client_secret": settings.TRUELAYER_CLIENT_SECRET, "redirect_uri": REDIRECT_URI, "code": code, } try: data = requests.post(TOKEN_URL, data=token_data).json() access_token = data.get('access_token') refresh_token = data.get('refresh_token') if access_token: query_params = urlencode({'token' : access_token}) response = HttpResponseRedirect(f'{FRONTEND_URL}?{query_params}') response.set_cookie(key='refresh_token', value=refresh_token, httponly=True, secure=False, samesite='Lax') return response return HttpResponseRedirect(f'{FRONTEND_URL}?error=No access token received') except Exception as e: return HttpResponseRedirect(f'{FRONTEND_URL}?error={str(e)}') I set the cookie refresh_token in the response. But in my next method, which is the method called to refresh the access_token when I try to access my refresh_token from cookies I get None: def check_refresh_cookie(request): refresh_token = request.COOKIES.get("refresh_token") # … -
Does Django automatically recognize registration/login.html as the login template?
Does Django automatically recognize registration/login.html as the login template? I'm working on a Django project and want to use Django's built-in authentication system for user login. If I don't set in url in urls.py My question is: Does Django automatically recognize registration/login.html as the default login template? If so, how does Django determine this file's location? Do I need to set anything in settings.py to make this work? Where is written the logic for this built in login -

Split data of an Ajax call to multiple div in Django
I have this ajax call $.ajaxSetup({ data: {txtSearch: $('#txtSearch').val(), prefilter: $('#prefilter').val(),csrfmiddlewaretoken: '{{ csrf_token }}' },}); $.ajax({ type: "POST", url: "article-filter2/", success: function (data) { $("#div_tab_search_results_contact").html(data.html_table); // working $("#div_tab_search_results_company").html(data.html_table); // not working if I call it a second time } }); data.html_table contains 2 tables and I would like to put the first one in $("#div_tab_search_results_contact") and the second one in $("#div_tab_search_results_company") based on the id's of the tables. I tried to search but what I found was in PhP Not able to split the Ajax response in separate Div Here is the end of my view.py article-filter2/ : def article_filter2(request): data = dict() [...] data['html_table'] = render_to_string('grid.html', {'available_lessons': available_lessons, 'available_lessons_company': available_lessons_company },request=request) return JsonResponse(data) Thanks to anybody that can help me
