You need websockets to have real time connection with your client

Or every 30s req backend which is not a good idea

have other way

Only way for real realtime connction is websockets it's simple

You need django channels

And socket.io or ws module in client side

have other way

Or in worst way request every minutes like (iranian goverment websites😂)

Or watch your database filesystem

There are many ways but standard is ws

Friends, I really need help with deploying a Django project on a Linux server. I'm using the Oracle Cloud service. We have a Ukrainian project and the task is to create an informational bot for internally displaced people. Unfortunately, the project doesn't have a budget, only volunteer work. I've already written the bot and its Django admin panel, but I've been trying to deploy it for almost a week without success. Perhaps someone could assist me with this task?

Hi all. I need some advice. I have driver's locations (lat,long). I used redis cache to save them. Now I have to find drivers in given radius. I go through to list again and again every time. I am going to know is there any better aproach for this. Thanks for answers.

Help please I'm building a Django based app and I was asked to do few steps in the project . First one was data base using models.py ( I also configured MySQL in settings.py Second step I'm asked to do a data access layer ( using Django orm ) I know that DAL is used to interact with my database ( I was asked to use one class DAL based on CRUD for example to read customers update or delete and so on . So where and how do I work with the data access layer . Which file to implement it into ? Vies.py ? Any help is good Thank you

I would do this - depending on the scale of the map, try to divide your map into square sectors (say 1km to 1km). After you update the location of a driver, assign him a sector that he is in. If you have many drivers, it would be easier to just select drivers in a certain sector and work with them. It depends a lot on radius etc., but I would calculate on location update 100%

I use LoginRequieredMixin on my view which redirect user to login page if user is not authenticated. What I want is to modify login page context when redirecting. For example if user wants to see his/her profile and not logged in, redirect to login page and write "Please login first". How is this possible?

DAL is not a common thing on django, so you can put it in any file and the use it from views

Since it's something related to database , is it a good practice to put in models ? Business logic also goes inside models ... the file will be full of code . Not too much ?

Hi all! Please tell me, I'm doing a 3-step registration, using 3 forms that inherit from ModelForm and view classes that inherit from FormView. The first two pages were ok. On the first, I write down the first name, last name, mail and number in the session. On the second, I confirm the mail using the code. But there is a problem with the third page. There should be two fields: 1) Enter password 2) Enter the password again. And here in the form I don’t know how to make the password validation be from Django (well, that is, checking for length, characters, similarity between the first and second input field, etc.). Tell me, please, how to do this? From what class to inherit in the form?

You can either use the permissions module that is built into Django or you can have a role field in your user table with different values ie admin, staff, writer, employee and so on

i have a form in the react app i just want to retrieve data when submit and sen them to the django backend app

i have a form in the react app i just want to retrieve data when submit and sen them to the django backend app

If you have a react app you should consider to build a rest api, but if you only need to fetch data from a “side” backend that has not an api you can create a “regular” function-based view that returns a json instead of a template, this needs the csrf_except decorator. This will emulate an api’s endpoint but it’s not a secure method. I recommend to add rest framework to your backend.

Learn Both, build the same REST APIs with Django+DRF and NodeJS+Express. But if you must choose then learn Django and then DRF soon after. And then when you've built a few APIs you can learn Typescript and Vue/React to build frontends that consume you're APIs

With experience building backends with Python and Django as well as frontends with NodeJS, Typescript and Vue/React then you'll find it really easy to learn how to build backends with NodeJS and Express

How can I authenticate an user across multiple databases without configuring in settings.py

Auth0 maybe? and then you keep your individual client databases will be only for application data. But you have to config settings.py no matter what auth method you choose

Thank you for the suggestion 🙂

No prob: Start with Django

How to disable certain options of a ForeignKey field using crispy forms? The form inherits a ModelForm, and the model has a ForeignKey to another related model. I still want to display all related model instances as dropdown options, but disable certain ones. Modifying the queryset alone isn’t enough because I still want to display all of them, with only certain options shown as disabled.
