Thanks,
I tried the format you sent me earlier but when I tried to access the
args parameter inside the function, it is showing me the error:
{"inputs":['.$k.'],"query":[{"map":{"language":"javascript","source":"function(value,keydata,"arguments"){
var data = Riak.mapValuesJson(value)[0];
var obj = {};
obj[value.key] = {};
for(var i=1;i<3;i++)
{
var gender = \"G\"+ i;
obj[value.key][gender] = {};
for(var j=1;j<=6;j++)
{
var agegroup = \"A\" + j;
obj[value.key][gender][agegroup] = {};
obj[value.key][gender][agegroup][\"cpc_median\"] =
data[gender][j][agegroup][\"bid_estimations\"][0][\"cpc_median\"];
obj[value.key][gender][agegroup][\"users\"] =
data[gender][j][agegroup][\"users\"];
}
}
return [obj];
}","args":{"gender":"G0,G1","agegroups":"A0,A2","metrics":"users,cpc_median","groupby":"country"},"keep":true}}]}';
Please help me on the above.
To clarify my requirement, I would like to access the args parameter
(before keep parameter) inside javascript function and if possible I would
also like to know the flow that what is the need for args param after js
function.
Thanks,
Venkatesh.Y
