How can I set up filtering in the form model of one field based on another when selecting?
I have 2 model tables. In the first table I have a form in the set in which there is one interesting field. This field can have the same values. If we consider the second table model - then in the second table model I placed 2 fields from the first table. And in these two fields - there is a field in which there can be duplicate values. I would like, if possible, to enter data into the second table - taking into account: selection of data from the city field and most importantly - so that after selecting in the city field - some filtering of the second field occurs. For example, filtering of two fields occurs according to the selected first field and is substituted into the second field. How can this be done. I select the city field - and so that the second field is filtered. How can I set up filtering in the form model of one field based on another when selecting? Help me please, I will be glad to any hint on how to do this? from django.db import models # Create your models here. TYPE_OBJECT = [ ("1", "Котельная"), ("2", "Сети"), … -
Production server Bad Request (Error: ValueError: Unknown endpoint type: 'fd')
This morning, my production website went down with a "Bad Request" error. It was working the day before, and I made no changes that might have caused the error. Below is the traceback I got in the asgi.log file. I can provide more information if needed, but not sure what. I have tried the following: Uninstalled all from requirements.txt, then reinstalled, and restarted the server Added '*' to ALLOWED_HOSTS, and set DEBUG=True, but this did not work, so I undid those changes. Rebooted the server The site works fine in my local machine, whether I use DEBUG = FALSE or DEBUG = True.

How can I configure the wrapping of a large long line of text in a form Django?
I have a form with OneToOneField where data is loaded from another table model. But I often have large data sizes there and the displayed text does not fit into the window size.

Django URL matching but displaying 'Page Not Found'

Django Multi-Database ValueError: "Cannot assign Role object: the current database router prevents this relation"

How to access a Django site from another device on a local network
I'm running a Django site on my computer and I want to access it from another device on the same Wi-Fi network (for example, from a phone or another laptop). I tried running python manage.py runserver, but I can only access the site from the same computer using localhost. I don’t know how to make the site accessible from other devices. How can I properly configure Django and my computer so that the site is accessible from other devices? To be honest, when trying to find a solution, I found a couple of options where I needed to merge the project into different services, but that doesn't work for me. Thanks in advance! -

How do I structure a Django REST Framework API backend when the frontend is already built?
I'm building a Visitor Management System (VMS), and I've been given a complete frontend to work with. My task is to build the API-based backend using Django and Django REST Framework, which I'm familiar with from smaller projects. However, I'm struggling to organize the backend efficiently and expose the right endpoints that match what the frontend expects. Set up Django and Django REST Framework. Defined my models (e.g., VisitorPreRegistration, User). Started creating serializers and basic viewsets. My Questions: What is the best way to structure a Django API-only project, especially when the frontend is decoupled? Are there packages or patterns (like cookiecutter-django, DRF extensions, or project templates) that help speed up development and reduce boilerplate? How do I effectively map frontend forms and filters (e.g., visitor type, host search, arrival time) to backend endpoints? 🔍 What I tried: I’ve read the Django and DRF documentation, and tried watching a few YouTube tutorials, but most assume a monolithic approach or skip the API-only setup with an existing frontend. -
django-minify-html breaks Google Analytics injection

How do I write a Django ORM query that returns a match based on an intersection of lists?

Should I really use React/Vue with Django instead of Alpine.js?
I have a page where user creates an instance. An instance has a bunch of characteristics and foreign key to product (which has category and name itself) and all the fields are static - just stylized selects and inputs, but there is just a change event handler which saves any changes in session so that user could go back to editing With Alpine.js I replaced two selects (where user chooses product category and product name) with a single button - "select a product" and after clicking a modal appears with options depending on the step - either category or name, once both category and name are selected a card with this product appears and a button turns into "change a product". Everything worked just fine until I started filling this with initial values from draft form, so that you need to combine Django {% if %} with Alpine.js x-if which caused flickering. Is it really worth it to switch React/Vue + DRF or am I missing something? Considering my codebase it would be painful, but pretty much possible. The only negative thing that stops me from doing it right now is Django features I don't want to rewrite in JS … -

React + React Native + Django AllAuth
I'm running a Django server which has API's I consume through a React Native and React applications. I want it to work for Google, Facebook, Instagram and Twitter. For this question I want to focus on the React Application and Google Authentication and hopefully it will be repeatable for my other social options. My React Application manages to login just fine for Google It returns field called "credentials". My thinking was I can send this to Django AllAuth, which would call google and then return user data, which I can create a Django User and sign in and if that user already has an account it just login. Some features on the API require users to have loggedin. I have the same client_id for my React and Django app. Does AllAuth do this already ? How do I work with it? When I try forward my 'credentials' (the one google returned to my React) to auth/google/ I get a 403. I would imagine I don't have to do this pragmatically as this seems like a pretty common setup . Any guidance on how I can make these React and Django AllAuth work together would be great. -

Additionally i have a middleware that doesn't interfere with requests but i have disabled it and result is just the same.
