Hi All
I am building a website which makes calculations about the visibility of
satellites. These calculations take about half a minute so I do not want
to block the site during this time. I found django-rq and was able to
start a asynchronous task which handles the calculations.
The problem
Hello,
One simple approach is to persist the calculations in the database, then

(Note: The most popular way to do asynchronous tasks is celery, but indeed some
people prefer django-rq, which is said to be simpler. But your question is not
affected by that.)
I'm not an expert but I think that the "correct" way to do what you want would

Web pages cannot be "called". They are loaded by the browser. So, what you want
is a mechanism that notifies the browser that an event has occurred in the
server. That mechan

Hi All
I spent several days reading and searching examples of how to implement
channels. The current status of my project is as follows:
- I have a page which lets the user enter the data used for the offline

Hi Alain,
I'm not quite sure what you're trying to accomplish by mixing rq and
channels; Channels just allows you to either write things against WebSocket
