abort in rails loop function

I've got a function in my rails controller (I know, not the rails way, but I find it easier to write in the controller when I have something big like this and then move to the model).

I have an error in a array that I'm looping through, unfortunately, the error is being added somewhere in the loop. It is a big array with lots of properties, and I'm trying to figure out where the error is being caused.

I think I can isolate which object in the array is causing the error, but I can't get it to print.

Aparently ruby has an 

abort('message')
function, but that returns an error in rails.

return render isn't working, it gives me an error that render and/or redirect is being called multiple times. How can I do a php type die in this situation?

This SO Post makes an excellent suggestion.

raise RuntimeError, 'Message goes here'

In the 'Message goes here' section you could even add in the array element:

array.each do |array_element|
     <logic>
     raise RuntimeError, "#{array_element.inspect}; Message goes here"
end
