Django - How to create updating progress bars?

I'm wondering how should I go on and implement an updating progress bar. Basically the server should periodically send a confirmation on what is the current progress to the user.

I know how to do an Ajax call with Django and jQuery, which is similar to figure 1.

enter image description here

On my webpage, what happens is that a "processing" text box appears in the middle of the data the user wants to view.

However, I want to make it so that I could send periodic update to the user. For example, instead of "processing", I want to print out it's currently processing X, Y, and then finally Z, shown in figure 2. enter image description here

If I use my method in figure 1, if I send anything back to the server, it will end the ajax request and jump to "success" in jQuery. Is there a way to constantly send data to the user without ending my ajax call?

Can anyone point me to the right direction?

Have the request that generates the dictionary write its progress to a database, and have a second ajax request polling the server to check the progress and report to the user.
