Hello, I need to do both form level and model level validation (my app will be called by XML-RPC and it will also be used with the normal admin GUI) on a m2m relation.
The problem is that I have a m2m between "Items" and "Categories", "Categories" are organized in a tree with MPTT django-mptt. I want to avoid that "Items" are assigned to non-leaf "Categories". It seems like "save_m2m" (for forms) and "add" (for models) are created at runtime and it's not easy to override them. I'm using latest trunk and google'd searching for a solution, before going down to the DB level with some triggers and checks, does anybody have any idea or suggestion about if and how this could be done? -- Alessandro Pasotti w3: www.itopen.it -- You received this message because you are subscribed to the Google Groups "Django users" group.
