Quickly remove empty attributes from returned hash by adding remove_empty_attributes! method

[cmrichards]

It would be good if the hashes returned from form.save had a method that would remove all of the empty hashes. This would save some time spent manually removing all the empty attributes from hashes. e.g.

form.save  do |data, nested| 

  # do processing with the nested attributes here, run delete_if or whatever ... 

  # Remove any un-needed empty attributes
  nested.remove_empty_attributes! 
  # or...
  nested[:contracts].remove_empty_attributes!

   # Create using accepts_nested_attributes_for
  Job.create(nested)   
end

Could this easily be done by subclassing Hash?

I'm sorry but this kind of functionality will not be added to virtus. It's not meant to be used as an input data sanitazer or validator.
