ruby on rails - Why does the JSON returned from my Sinatra App give a syntax error? -

-

i'm developing sinatra app, returns json, e.g.

  '/clients'       # stuff       response = {        "success" => "true",        "msg" => "clients retrieved",        "data" => {"clients" => @current_user.clients}      }      return response.to_json   end

the returned json looks this:

{"success":"true","msg":"clients retrieved","data":{"clients":[{"client":{"created_at":"2013-03-31t22:50:18z","email":"test@test.com","first_name":"marge","gender":"f","hairdresser_id":2,"id":1,"surname":"simpson","updated_at":"2013-03-31t22:50:18z"}}]}}

when copy , paste json parser, works fine. http://json.parser.online.fr/

but when fire irb , try use it, bunch of errors:

1.9.3-p286 :001 > = {"success":"true","msg":"clients retrieved","data":{"clients":[{"client":{"created_at":"2013-03-31t22:50:18z","email":"test@test.com","first_name":"marge","gender":"f","hairdresser_id":2,"id":1,"surname":"simpson","updated_at":"2013-03-31t22:50:18z"}}]}} syntaxerror: (irb):1: syntax error, unexpected ':', expecting tassoc = {"success":"true","msg":"clients success...            ^ (irb):1: syntax error, unexpected ',', expecting $end = {"success":"true","msg":"clients r...                   ^   /home/[me]/.rvm/rubies/ruby-1.9.3-p286/bin/irb:13:in `<main>' 1.9.3-p286 :002 >

anyone able offer insight? doing wrong?

thanks alot

problem

json doesn't constitute valid ruby hash. it's string need parse json#parse.

solution

parse json string enclosing in single quotes or ruby quote literal. example:

json.parse %q/{"success":"true","msg":"clients retrieved","data":{"clients":[{"client":{"created_at":"2013-03-31t22:50:18z","email":"test@test.com","first_name":"marge","gender":"f","hairdresser_id":2,"id":1,"surname":"simpson","updated_at":"2013-03-31t22:50:18z"}}]}}/ => {"success"=>"true",  "msg"=>"clients retrieved",  "data"=>   {"clients"=>     [{"client"=>        {"created_at"=>"2013-03-31t22:50:18z",         "email"=>"test@test.com",         "first_name"=>"marge",         "gender"=>"f",         "hairdresser_id"=>2,         "id"=>1,         "surname"=>"simpson",         "updated_at"=>"2013-03-31t22:50:18z"}}]}}
