Basically, for now, idea is to have both class versions in assembly. For example, if for class "Person", i would also have old versions as "Person_0", "Person_1", etc., plus any changes registered between them. When I decide to rename some field in Person, I would need to: - Copy Person class to Person_2 - Make changes to Person - Map changes I made (example here in "InitUpgradeMap" method: http://github.com/Nercury/fluent-nupgrade/blob/07bdd91750cccc125a88390e9bb54d306c6758ae/examples/postgre-test/NUpgradePostgresTest/Program.cs) - Up the database version and register this change (possibly, with changes to other entities)
As I said, interface is highly in flux, it may be automatic later but even manual way to register changes would be awesome for now. I have some trouble understanding whole picture of NHibernate and FluentNHibernate, so if anyone want to help to push project forward, please don't hestitate :) On 18 Lie, 16:12, Paul Batum <[email protected]> wrote: > Interesting.
