Story only changed fields in object about whatwasit

[Eiji7]

I rewatched code in templates. Actually model is saved (old values).
whatwasit/priv/templates/whatwasit.install/models/whatwasit/version.ex:115
whatwasit/priv/templates/whatwasit.install/models/whatwasit/version_map.ex:115
Is it ok to change it like: object: model, => object: changeset.changes,?

Need to understand what happens if schema changes, especially if there are default values. If a full copy of the model is saved, then it possible to see the before/after changes.

1. If we add column with default value (mix ecto.migrate) we can manually insert version (helper function? - if we event want do it - I mean assumptions of the final project).
2. If we remove column - it's ok this data was in source table, sometimes we rollback migration and I think that it's good to keep this data. We can also save migration number to allow revert with removed data from source table.
