Import data maintaining timestamps

[ggtrigg]

I'd like to be able to import data from another database and keep the created_at & updated_at times. From everythig I've tried it seems like granite always overrides these on create even if those values are explicitly provided.

You should be able to do bulk imports using import interface and not have it override the timestamps
https://github.com/amberframework/granite/blob/master/docs/imports.md

Did this also override your timestamps?

[ggtrigg]

The import interface does override any supplied timestamps. I got around it by making a local modification so that the import only sets the timestamps unless created_at & updated_at are supplied. vis.

model.set_timestamps if (model.updated_at.nil? || model.created_at.nil?)

model.set_timestamps

If it helps I could raise a pull request with this change (and also for the other db adapters)?

@ggtrigg this is resolved with the new skip_timestamps option that can be passed in
