Using JBuilder (Ruby), how to create an array of hashes -

i using jbuilder ruby, , want create json hash looks this, end result:

"must" : {    "ids" : {        "values" : [1,2]    },    "range" : {        "visits" :           {            "gte" : 10          }     } } 

keep in mind have no existing array iterate over. examples i've looked @ assume have array. don't. want create json on fly.

i don't recommend using jbuilder static data. whole point of jbuilder provide dsl converting complex object graphs json. in case, might convert ruby hash json directly:

require 'json' # you'll need type of json library provides `hash#to_json` {   must: {     ids: {       values: [1, 2]     },     range: {       visits: {         gte: 10       }     }   } }.to_json 

for learning's sake, here's how you'd build same json string jbuilder manually:

json = jbuilder.new  json.set! :object   json.set! :must     json.set! :ids, [1, 2]   end   json.set! :range     json.set! :visits       json.set! :gte, 10     end   end end.to_json # note jbuilder returns hash need converted
