ruby on rails - Error parsing JSON: undefined method 'gsub' -

i'm trying parse json in javascript, i'm getting error in rails:

undefined method `gsub' #<array:0x000001054a2440> 

my code follows:

<script type="text/javascript">   var stuff = <%= escape_javascript(@json) %>   var json = stuff.parsejson();   alert("text"); </script> 

where @json defined in controller @nodes.to_json

can please me this? getting json javascript shouldn't hard, it's taking me forever.

the code escape_javascript is:

def escape_javascript(javascript)   if javascript     javascript.gsub(/(\\|<\/|\r\n|[\n\r"'])/) { js_escape_map[$1] }   else     ''   end end 

thus, conclude @json array.
