I've done something similar to what you are describing, using jQuery, the dynatree jQuery plugin, and some reasonable Django code. The code is available at http://bitbucket.org/tpherndon/django-fedora/, and you'll specifically be interested in the djadora/views/browse.py and the djadora/templates/fedora/browse_dynatree.html and image_fragment.html files. I implemented the code as part of a special-purpose web app for interfacing with a Java repository system, and the code is far from clean and pretty, but it should give you a decent example of something that is currently in production. The way I approached it was to write a couple of views that are designed to handle the jQuery dynatree Ajax requests. Dynatree does the work on building the tree in HTML, my views provide the data, and the models each have a "parent" attribute that allows the views to figure out how to select children for each tree level. In retrospect, I'd do my best to reuse django-mptt, django-treebeard, or similar. They aren't a direct fit for my use case, since I have different models that can contain each other, and from what I've seen they are geared to handle only a single model class pointing to itself, but I would follow their approach and steal code like crazy. :) Or, if I had just one kind of model, I'd just add enough Ajax views to power dynatree. ---Peter --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
