Many web sites offer faceted browsing such that a series of categories can be selected to narrow a large set of records down to a few (or one). Such interfaces often show how many records match the various category values, which sometimes helps direct the search. Likewise, since only valid combinations of categories values are shown and selectable, the problem problem of constraints with zero results are mitigated. You can see this in action on lots of shopping sites: Amazon's page on diamond wedding rings (http://www.amazon.com/gp/ search/ref=sr_nr_n_2?rh=n%3A3367581%2Ck%3Adiamonds%2Cn%3A!3880591%2Cn %3A3887251&bbn=3880591&keywords=diamonds&ie=UTF8&qid=1257740168&rnid=3880591) is a good example.
I'm an intermediate-level Django user, and i'm trying to conceive how to architect a faceted browsing application in Django. I can see conceptually how a combination of constraints specified in the interface could translate into a series of filter statements on a model, and i can see how, with some constraints in place, the remaining values and the number of records matching them could be computed and presented. But I'm less sure how to provide a RESTful interface (since any of several constraints can be selected independently) in an efficient manner, or how to work out the template details. So i'm looking for some direction. Are there any Django sites out there already that use an approach like this? Or suggestions as to how to architect one? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
