I've been trying to dockerise my django project with postgresql but have been running into this same problem time and time again. web_1 | CommandError: You must set settings.ALLOWED_HOSTS if DEBUG is False.

Django webserver automatic failover design
I am trying to build a Django backend system combined with Celery. The idea is that there is a list of 500+ websites that will be processed by Celery every 5 min. Since it involves a lot of network operations which can take any amount of time and we have time constraint of 5 min, we are planning to have multiple Django webservers running in parallel with each processing some amount of websites. The idea is that each Django web server will process (500+ list of websites) / (total number of Django websites instances running), this way we can distribute the workload and in case if anyone goes down then others can take over. I have created a heartbeat rest API which other Django webservers will use to check the status of other servers but how can I make it scalable? What I want is each web server will auto-detect how many others are running and then will process the list accordingly, for example, if there are 5 web servers running then each of them will process only 100 websites, the first server will process first 1-100, then the second one will process next 101-200, the third one will process … -

Django [WinError 10053] when loading up server
Whenever I start up my Django server i get the errors shown below. The weird thing is that sometimes the [WinError 10053] doesn't show up and I can develop normally but when it does show up the project seems to malfunction and .css and .js files also don't get loaded. I have already looked into other stackoverflow questions that seemed related such as setting the correct code page to use with postgres or the python bug mentioned here https://bugs.python.org/issue27682. But I'm using python 3.9 so that bug should be fixed. Does anyone know how to fix this? The project works just fine on the computers of some other people and everything that we compared seemed the same (settings, pycharm configuration,...).

How to create Model with nested object in Django
I'm trying to create a small product manufacturing app with Django. There are two main models in the app. class Product(models.Model): name = models.CharField(max_length=100, blank=True, default='') class ProductionOrder(models.Model): created = models.DateTimeField(auto_now_add=True) entries = # not sure what goes here I would like ProductionOrder.entries to be a list of dictionaries which include the Product and a quantity value. The created ProductionOrder would appear as so (not exactly sure : productionOrder = { 'id': 2, 'entries': [ { 'product': 'product_1_ref', 'quantity': 10}, { 'product': 'product_2_ref', 'quantity': 10} ] } How can I accomplish this in a correct way? -

Websocket disconnects immediately after handshake (guacamole)
Forgive bad formatting as it is my first question on here, and thanks in advance for reading! I am currently writing a remote web application that utilises Apache Guacamole to allow RDP, VNC, and SSH connections. The components I am using are: Django for backend server - API calls (database info) and Guacamole Websocket Transmissions; I am using Pyguacamole with Django consumers to handle Guacamole Server communication; Reactjs for frontend and proxy; Nginx for reverse proxy; All this is hosted on a Centos Stream 8 vm Basically, my websocket has trouble communicating through a proxy. When I run the application without a proxy (firefox in centos running localhost:3000 directly), the guacamole connection works! Though this is where the application communicates directly with the Django server on port 8000. What I want is for the react application to proxy websocket communications to port 8000 for me, so my nginx proxy only has to deal with port 3000 for production. Here is the code I have tried for my react proxy (src/setupProxy.js): const { createProxyMiddleware } = require('http-proxy-middleware'); let proxy_location = ''; module.exports = function(app) { app.use(createProxyMiddleware('/api', { target: 'http://localhost:8000', changeOrigin: true, logLevel: "debug" } )); app.use( createProxyMiddleware('/ws', { target: 'ws://localhost:8000' + … -
Django multiple parents and every parent may have the same children, but changing one children should be changed for this parent not the others?
I have a system for ambulance service built with Django, React for the API and dashboard and Android for the mobile app, where crew belong to an ambulance and ambulance has calls and every call has forms and every form has questions Now when crew login to mobile app he will see his ambulance details and its calls and inside each call he will see the forms Now crew need to do two things, submit forms and submit call In case submitting a form it should be showed on the admin dashboard a list of submitted forms and in case to submit a call, crew must submit first all required forms inside that call, and submitted calls should be showed on the admin dashboard Also I need to make checkbox done on the mobile app to the submitted call or form To solve this, I added a boolean field for the call model and form model to check if call or form is submitted Now the client didn't want that, because he could assign the same form or call for another ambulance that has different crew, so in my case if another crew logged to the app he will see … -

How to update a specific value of a object present in array of object within Postgres JSON Field
Here is my JSON field value. which is stored in the PostgreSQL table. I want to search and update the specific user_name in the user key { "user": [ { "user_name": "Devang", "user_weight": 0.7676846955248864 }, { "user_name": "Meet", "user_weight": 0.07447325861051013 }, { "user_name": "L.b.vasoya", "user_weight": 0.056163873153859706 } ], "address": [ { "address_name": "India" } ] } whose name is Devang to Dev using Django JSONField for example "user": [ { "user_name": "Dev", "user_weight": 0.7676846955248864 }, .... I have tried the RAWQuery for the find. This is the query. ``` select json_field->user from user_table where json_field @> '{"user": [{"user_name": "Devang"}]}'; It will return like this ```[ { "user_name": "Devang", "user_weight": 0.7676846955248864 }, { "user_name": "Meet", "user_weight": 0.07447325861051013 }, { "user_name": "L.b.vasoya", "user_weight": 0.056163873153859706 } ] I have also tried JSON_SET to update the user_name but JSON_SET only accepts. It will update the upper level, not a nesting level
