Question

I have a model. I want to clone it.
But after I run model.save! my before_create callback aren’t fired.
So, I’m wondering is it some trick to make rails think that this clone object is actually the new one.

Thanks

That’s the expected behavior in Rails 3.1. On the Active Record CHANGELOG:

Calling ActiveRecord::Base#clone will result in a shallow copy of the
record, including copying the frozen state. No callbacks will be
called.

You can use dup. It will run the before_create callback.
