initialize_copy(other) — ActiveRecord::Base

initialize_copy(other)

Cloned objects have no id assigned and are treated as new records. Note that this is a “shallow” clone as it copies the object’s attributes only, not its associations. The extent of a “deep” clone is application specific and is therefore left to the application to implement according to its need.

Parameters
