If it were the case, it'd be farily easy to find what you need, true. However - what you're trying to do looks a bit too specific to handle it in such a generic way. If you have a discussion list, probably the posts in it follow some logical flow that you don't want to disrupt - is that the case ? What I mean is - would you have views, that display your model items with different order_by clauses ? If not - there is an answer to "If I could find an efficient way to do "find the index in the given qs of the object with pk = <foo>" - add an extra column in your model that describes that, and use it to find the page for your permalinks. You could keep the page, where each item is located in, but that's not a good solution, since it'd force your views to a singe page size. I'm interested a way that could be handled as well, if there are any reasonable solutions --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
