class User < ActiveRecord::Base
  has_default_value :name
end

In config/locales/en.yml:

en:
  activerecord:
    defaults:
      user:
        name: no name

Then application behaves as follows:

$ bin/rails c
> user = User.create
>

class User < ActiveRecord::Base
  has_default_value :name, :email, :address, ...
end
