I found a method to convert the keys that are string to symbols. I

def key_strings_to_symbols!
r = Hash.new
self.each_pair do |k,v|
if ((k.kind_of? String) and k =~ /^:/)

else
v.key_strings_to_symbols! if v.kind_of? Hash and
v.respond_to? :key_strings_to_symbols!
r[k] = v
end
end
self.replace(r)
end
end
why not use what Rails already provides via symbolize_keys! .....
