You can use to_s function to replace NIL to empty string. For example, you can put following code in your view. <%= obj.to_s %> If obj is NIL, it simply returns "" (empty string), and you can avoid runtime errors.

How can I get this so that the ouput is displayed as: [["one","","three"], ["","five","six"]]
testarray.map{|q| q.to_s }
This might even work:
testarray.map(&:to_s)
testarray.inspect.gsub('nil', '""')
If you need each element of the original array to being on its own line, you'll have to roll your own. If you do that, then each element could be: (element || "").inspect except that turns both nil and false to the "" string.

That idea is ... disturbing on many levels. To begin, what happens when one of the string elements is 'Manila'?

In the case of 'manila' manila is still printed out or whatever string content the variable may hold
p 'manila'.gsub('nil', 'ni')
Since it wasn't *my* problem, I tried not to go crazy looking for a solution.
