Question

I am creating a webapp with django in which it reads some data from a text file and then preview it to a web page and I want that the data get automatically update on changes(or time to time) without refreshing the whole page.

Answer 1

Thanks for tagging

Are the changes triggered by

the current browsing user only?

Or some other users using at the same time?

Or API and occur at the data?

For first case, you can use a frontend framework like React, Angular or Vue.

The content can get updated automatically when the state changes.

If it is peer-to-peer, use Web Socket.

If it is changed at data, you can set some triggers at the database.

Gordon I am trying to build a simple (very simple universal chatting app) with django. For basic purpose I am storing all the messages in a text file. The problem is that messages are not getting updated automatically, we have to refresh the page to get updates.

I think your second link may work for me. I will see the video...

You can use Ajax for the thing you looking for
I am also making a chat Web application using django where I will be using Ajax to send and receive message from my django views.
You can also refer to my project
https://github.com/Ajay2810-hub/AwesomeList

The Ajax code is in static/js/AwesomeList/index.js line no. 194

and the view reading the message is at designer/views.py -> functions mark_complete and delete
