I'm migrating my old blog posts into my new Rails blog, and I want their updated_at attribute to match the corresponding value on my old blog (not the date they were migrated into my new Rails blog).
How can I do this? When I set updated_at manually it gets overridden by the before_save callback.
Note: This question is only valid for Rails < 3.2.11. Newer versions of Rails allow you to manually set timestamps without them being overwritten.
