How to send data from view to template continously in Django

Question

I need to send data from my view or my model database to my HTML/javascript template. What technology or methods should I use for that? I can’t simply use for example

return render(request, "check_by_callsign.html", {"latitude": latitude, "longitude": longitude})

because that would only mean one return of data.

It’s not that easy to implement websockets in Django (async programming). This is being worked on, in the meantime look at Django Channels

To poll your view every x second you can use the Fetch API within Javascript:

const myDiv = document.getElementById('coordinates')

function fetchCoordinates() {
  fetch('yourURLhere')
    .then((response) => response.text())
    .then((data) => myDiv.innerHTML = data)
    }

window.addEventListener('load', event => {
  let fetchInterval = 5000; // 5 sec, 10000 = 10 sec
  setInterval(fetchCoordinates, fetchInterval);
})
