The tricky bit here is, as you've probably realized, the different models. Django's QuerySet architecture, which is the obvious first place to try, can only handle a heterogeneous set of objects, so there's no direct way to do this with a QuerySet. What you *can* do, if you're willing to be a bit adventurous, is pull out the content you want from the different models you want, and dump the results into one big list (a list doesn't care what types of objects it contains). Then you can take advantage of Python's list-sorting facilities to specify how you'd like to sort; for example, if all your models had a commonly-named field to represent their publication dates (e.g., each one has a DateTimeField representing the publication date, and all three use the same field name), it's relatively easy to get Python to sort the list by that field -- look at the 'sort' method of Python's List class, which lets you pass in custom comparison functions to be used in sorting. -- "Bureaucrat Conrad, you are technically correct -- the best kind of correct." --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
