insert value of primary key into another field before record is saved
...assign it to another
field of the same record called ''sequence''. So if the primary key of
the record is 23, then the sequence should also be 23. But the record
is not created yet, so it doesnt have an id yet.
I tried doing this in subbook model:
belongs_to :book
before_create :add_sequence
def add_sequence
self.sequence = self.id
end
But that didn''t do anything at all when running the seed task.
Any idea how to update another field with id of record before that
record is saved to database?
Thanks for response
