What's this?

dup public

Duped objects have no id assigned and are treated as new records. Note that this is a “shallow” copy as it copies the object’s attributes only, not its associations. The extent of a “deep” copy is application specific and is therefore left to the application to implement according to its need. The dup method does not preserve the timestamps (created|updated)_(at|on).

Parent associations are kept

Maybe this information will save you some time: parent associations (i.e. associations with foreign id in current record) are copied. Don’t assume you’ll get a safely editable object.
