Instance Method Details

#prepare_versioned_options(options) ⇒ Object

After the original prepare_versioned_options method cleans the given options, this alias also extracts the :if and :unless options, chaning them into arrays and converting any symbols to procs. Procs are called with the ActiveRecord model instance as the sole argument.

If all of the :if conditions are met and none of the :unless conditions are unmet, than version creation will proceed, assuming all other conditions are also met.
