Hi all, I recently solved a problem with a field that could not be ordered as I wanted. It was a CharField containing of exactly seven numbers like 9900000, 0100000, 1200000 etc. The first two digits indicated a year (99 being 1999 and 12 being 2012). The ordering should be different from usual, namely: 5000000, 5000001, ..., 0000000, 0000001, ... , 4999999. So I hacked around with a model manager, and a special QuerySet, and reached a state with which I was almost satisfied. See http://djangosnippets.org/snippets/2861/ for the whole stuff.
There is even a special feature (totally optional) for databases which can do functional indexes to speed up the ordering. Sqlite would still work, although not quite as fast. I can think of a couple of other similar use cases e.g. a field containing strings like 'a1', 'a9', 'a10', 'a100' etc. where the usual alphanumeric sorting does not make sense. If there is enough interest, I could dig into Django core to make this whole functionality more generic, so it could be merged into a development branch in Django. I'd love to read some thoughts from you how / if I should continue from here. Martin -- You received this message because you are subscribed to the Google Groups "Django developers" group.
