ruby on rails - array of hashes as hash key and value as array using jbuilder -

i'm trying generate json response using jbuilder

i have array of hashes this

words=  [       {"term": "abc",       "definition": "123"       } ,       {"term": "abc",        "definition": "345"       } ,       {"term": "xyz",        "definition": "890"       }     ] 

i covert json. logic here take terms keys , push it's definitions arrays

  {      "abc": ["123","345"],      “xyz”: ["890"]     } 

what achieved far

words.each |word|     json.set! word['text'] ,word['definition'] end 

gives me

{   "abc": "123"      "abc": "345",   "xyz": "890" } 

could me on this.

simplest solution :)

words=  [       {"term": "abc",       "definition": "123"       } ,       {"term": "abc",        "definition": "345"       } ,       {"term": "xyz",        "definition": "890"       }     ]  result_hash = hash.new{|hsh, key| hsh[key]=[] } words.map{|x| result_hash[x[:term]].push(x[:definition])} 

your output in result_hash
