Rails Undo Redo Demo App

Home

This web application is an experiment to test a few ideas on how to implement Undo Redo for Rails. Give it a test drive.

Key ideas

• Works across all models
• Capture the list of changed objects (UndoRecord)
• Group these UndoRecords per User Action (UndoAction)
• undo and redo are just a simple matter of replaying the UndoRecords in the right order

By using a Rails plugin (or very soon a gem as well), you can very easily transform any Rails Application using Active Record into a full fledged multi level undo/redo application like most desktop applications.

Notice: This is a demo application, and as such, do not use to store any data you would not want to lose
