http://ruby-doc.org/core/classes/CGI.html The thing is, you've not said what your problem is, only asked for a way do what you think is the way to solve your problem. to turn a hash into a string of "key=value" for each pair separated by a space (which is what you've asked for), you could solve a dozen ways (without extending base ruby classes). For instance, this seems to do what you want: { :a => 'b', :c => 'd' }.inject([]) {|output, pair| output << "#{pair[0]}=#{pair[1]}"}.join(" ") but it's quite smelly code, and doesn't account for potential confusion that could occur to your output in the event that the hash was comprised thus: { :a => 'b e=f', :c => 'd a=c' } Explain your *problem*, ie: what is it that's causing you to think that that hash has to turn into a string; and you may find out that your approach isn't the most effective, and that someone suggests a more elegant/efficient/robust way to approach it.
