Hi,
Say I have model that comprises of Books and Authors. Where a book may
have multiple authors and this has foreignkey in the books table.
Now how do I prevent deletion of an author record while the there is
record in books table that has pointer an author record (via foreign key).
Do i need to do this via stored procedure/trigger on DB level or is
there standard procedure to implement this in delete in django?
Any decent database enforces foreign keys automatically.
