Re: How to make asynchronous ajax requests if the server side work takes plenty of time to finish?

I think a typical approach would be, using Django celery to process your heavy workload in the background, and then when finished, notify the user via email, text, or maybe have a periodic async ajax call check to see if there are completed tasks not yet looked at

I need advice or sample code to achieve a task related asynchronous ajax request that server side work takes plenty of time to finish its job.

Here is the sample scenario;

I've a simple CSV file upload form. User submits file

• Server starts processing CSV file.
• Server makes queries to external REST apis for each line of CSV file. (additional network request/response delays)
• Server parses each response (regex calculations, additional delays) and stores data into database.
• Server produces another output CSV file.

If the CSV file contains < 100 rows, it works even without using ajax. However I need to make it asynchronous to be able to feed a lot of rows. The critical part is I don't want to have timeouts as long as server side code is working. I want to be able to update client side regularly about the progress of work (log-like update, for example "x record is saved into database")

Can you provide me a working dummy sample code (for example, calculating fibonacci numbers) both client side and server side. (if possible django)

Thanks.

Regards.
