combinaut_rehearsal 0.1.4
Rehearsal is a Rack Middleware gem that allows model changes to be previewed without persisting them to the database. It achieves this by intercepting the original update request and spawning a second request to Rails for a preview, wrapping both in a single database transaction that is rolled back after the preview is generated.
