[Chicago] Django + AJAX

[Kevin Boers]

With regard to the 'polling' update of a specific div, I've usually done something like this:

    <script>
     $(document).ready(function() {
      $("#refreshing_div").load("django_view/");
       var refreshId = setInterval(function() {
         $("#refreshing_div").load("django_view/");
       }, 2000);
       $.ajaxSetup({ cache: false });
    });
    </script>

That will call the django view on document ready, and then again every 2000ms. In this case, the view would return plain html, but you can use a similar method to poll for json and do something with it using callbacks. The jQuery docs are awesome; see load() and getJSON() for examples.

Dear All,

What is the best practice of creating a django app with ajax? In
particular, polling (periodically updating a portion of a page) and updating
a portion upon an event (button click/link click/drop down menu).

Both of the features you mentioned depend mostly on Javascript - not
much on Django.  All of the popular js frameworks assist you in doing
ajaxy interactions.  The most popular among Django programmers I know
is Jquery, but Dojo also has a big Django following.

Besides the other places people suggested for searching, look in:
