>From what I read in the Django documentation and elsewhere on the Web, I do not think it is possible to define arbitrary data integrity constraints for a model beyond the options offered by each model field type. Do I understand this correctly?
I can see a few work-arounds. I could create my own custom field type and do the validation there, although I'm not sure whether that would let me do validation that refers to other fields (e.g., a constraint like, "the sum of field A and field B must be less than ten"). I can define my integrity constraints in the validation for the forms that act on the model, but this clearly breaks the "don't repeat yourself" principle, as I would have to repeat these constraints in every form (class) that I write. I could also override my model's save() method, but I don't think I would be able do anything about invalid data other than refuse to write them to the database. I don't think there's an exception I hope my question is clear. I'm quite the Django novice. Can anyone please tell me if I'm missing something? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
