#29156: Increase 'order_with_respect_to' features -------------------------------------+------------------------------------- Reporter: tapia | Owner: nobody Type: New | Status: new feature | Component: Database | Version: 2.0 layer (models, ORM) | Severity: Normal | Keywords: Triage Stage: | Has patch: 0 Unreviewed | Needs documentation: 0 | Needs tests: 0 Patch needs improvement: 0 | Easy pickings: 0 UI/UX: 0 | -------------------------------------+------------------------------------- With `order_with_respect_to`, we can do something like this:
{{{ class Book(models.Model): pass class Chapter(models.Model): book = models.ForeignKey(Book, on_delete=models.CASCADE) class Meta: order_with_respect_to = 'book' }}} It would be very nice to add some obvious features to this feature, for example: * `book.get_chapter_order()` returns the IDs of the chapters. Why not the chapter objects itself? * Given a chapter, we can get the next and the previous chapters, but we can't easily get that chapter's order. * It would be very nice to be able to add a chapter directly in a specific position, pretty much like python's `insert`. For example: `book.insert_chapter(chapter, 3)` I know it's a very broad request, but, if you guys like the idea, I'd love to take a look if I can add the functions myself (one at a time, to get your approval on each of them). -- Ticket URL: <https://code.djangoproject.com/ticket/29156> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
