I got the idea. But in my use case, foreign tables are not django-managed, they are very foreign, and database desintegrity is supposed by application design. As a validation, It's enough just to nullify a relation if related object suddenly disappeared - either at the moment of model retrieval, or when relation is referenced. Now I just wonder, if i have to implement such stuff from scratch, or there's some useful functionality in django internals. -- You received this message because you are subscribed to the Google Groups "Django users" group.
