arrays - Formatting ruby hash to json -


i current working on formatting data ruby json; current code looks 

def line_chart_data     @sources = ['facebook','twitter','instagram','linkedin']     @sourcecount = [5,12,16,6]     @weeks = ['one','two','three','four','five','six']      h = []     @weeks.each |i,v|         h.push({'v' => 'week ' + i})         @sourcecount.each |s|              h.push({'v' => s})         end     end     c = {c: h}       #how data should formatted on export     @sources2 = {       cols: [         {label: 'week', type: 'string'},         #each source needs looped though , formatted         {label: 'facebook', type: 'number'},         {label: 'twitter', type: 'number'},         {label: 'instagram', type: 'number'},         {label: 'linkedin', type: 'number'}       ],       rows: c      }        respond_to |format|         format.js {render json: @sources2}     end end

when data gets printed console looks (shortened little brevity)

"rows":{"c":[{"v":"week one"},{"v":5},{"v":12},{"v":16},{"v":6}, {"v":"week two"},{"v":5},{"v":12},{"v":16},{"v":6}, {"v":"week three"},{"v":5},{"v":12},{"v":16},{"v":6}]}

if notice first "c" opens array loops through above code not create new array each week. code should more this.

"rows":{"c":[{"v":"week one"},{"v":5},{"v":12},{"v":16},{"v":6}], {"c":[{"v":"week two"},{"v":5},{"v":12},{"v":16},{"v":6}]}, {"c":[{"v":"week three"},{"v":5},{"v":12},{"v":16},{"v":6}]}

where each loop of weeks array creates new hash key of "c" , value of array.

any pointing me in right direction appreciated! been stuck on quite while.

you need re-work code bit this. json want not valid, closest can get:

"rows":[{"c":[{"v":"week one"},{"v":5},{"v":12},{"v":16},{"v":6}], {"c":[{"v":"week two"},{"v":5},{"v":12},{"v":16},{"v":6}]}, {"c":[{"v":"week three"},{"v":5},{"v":12},{"v":16},{"v":6}]}]

code:

rows = [] @weeks.each |i,v|     h = []     h.push({'v' => 'week ' + i})     @sourcecount.each |s|          h.push({'v' => s})     end     rows.push({"c" => h}) end    #how data should formatted on export @sources2 = {   cols: [     {label: 'week', type: 'string'},     #each source needs looped though , formatted     {label: 'facebook', type: 'number'},     {label: 'twitter', type: 'number'},     {label: 'instagram', type: 'number'},     {label: 'linkedin', type: 'number'}   ],   rows: rows  }

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
