I've seen this question come up a lot and I'm not sure there's a standard
Pylons approach. It really depends on what you're trying to do.
One method is to transfer the data to Javascript separately. Once the page
loads (or some other event fires), send a request to the server and have it
return the data (via a separate controller action) in XML or JSON or some
other exchange format. This lets you keep a clean separation between the
HTML templates, the static Javascript files, and the dynamic data that the
Javascript acts on. However, there are situations in which it makes no sense
to use that approach.
Another option is to load part of it in a <script> tag in the HTML template.
For instance (using Mako):
<script>
var titles = [];
% for book in c.books:
titles[${book.index}] = '${book.title}';
% endfor
</script>
You can still load the Javascript code that uses that array in a separate
file, but the array itself will be loaded into the HTML document you send to
the user (keeping in mind that you can still find clever ways to use
namespaces to keep the Javascript relatively clean).
How does everyone else handle this? Maybe we can get something up on the
wiki about the best way to handle it in Pylons.
