ruby - Joining two arrays together to make json in rails -

i pretty ruby nuby i'm sure doing awful here. i'd join 2 arrays can pass controller json created. way can reasons of d3 library im using , requirements.

to have following in controller:

def self.including_relationships       result=[]     result['nodes']=user.pluck(:name,:group)     result['links']=relationship.select('follower_id source, followed_id target, value').map{|x| [x.source, x.target, x.value]}     result   end 

the controller:

def data      @users = user.including_relationships      respond_to |format|        #format.html # index.html.erb      format.json {  render json: @users }       end   end 

i end result, when passed through controller like:

{   "nodes":[     {"name":"myriel","group":1},     {"name":"napoleon","group":1},     {"name":"child2","group":10},     {"name":"brujon","group":4},     {"name":"mme.hucheloup","group":8}   ],   "links":[     {"source":1,"target":0,"value":1},     {"source":76,"target":62,"value":1},     {"source":76,"target":48,"value":1},     {"source":76,"target":58,"value":1}   ] } 

the table relationships correct (user relationship 1 many). think question of how can 2 queries combined format can render them in json in controller

to json in required format, need is, change array hash.

result = {} 

and may map call below, if need array of hashes, links

map{|x| {source: x.source, target: x.target, value: x.value} }
