[postmodern-devel] Defer creation of sequence ids?

[Vamsee Kanakala]

Hi,

I think, create-instance should defer the creation of an id (from 
sequence-next), because, there are some times when an object is created, 
but is not saved. For example, in a web application, I would need to 
create an object so that I can fill in the slots from the form values, 
but I might not save it, as it might have some validation errors.

It would save some sequence ids (a lot actually, as there might be 
multiple rounds of validation errors) if I don't have to assign an id 
unless it is being saved to the database. I think we could have 
insert-dao/save-dao to retrieve a new sequence id if the column "id" is 
not filled/nil/zero, and use an existing id if it's value is greater 
than zero. If this sounds ok, I can create a patch.

Regards,
Vamsee.
