Active Record to_hash

With this mix-in, you can have nice "to_hash" methods on your active record objects.

I find it good for programming JSON apps.

In lib/ar_hashing.rb



module ActiveRecordHashing

  def to_hash

      Hash[*self.map{ |m| [m.id, m]}.flatten]               

  end

end

and in config/environment.rb



require 'ar_hashing'



class ActiveRecord::Associations::AssociationCollection

  include ActiveRecordHashing

end

Sanitize runaway Z indexes!

This is a function I wrote to sanitize zIndexes of a list of elements that you may continually are bringing to the top of a page. This function goes through HTML Elements and makes all the numbers as low as can be without affecting ordering.

Feel free to make suggestions or to use this code how you'd like.

One condition, please just tell me if you're using it, and if you have ideas for improvement, let me know

function sanitizeZ(elements){



	function sortByZIndex(a, b){

		return a[1] - b[1];

	}



	var tempZArray = new Array();

	for(i in elements)

		tempZArray.push([i, elements[i].style.zIndex]);



	tempZArray.sort(sortByZIndex);



	for(i in tempZArray)

		elements[ tempZArray[i][0] ].style ['zIndex'] = i;



}
