Question

大家好我即将开始使用couchdb 我试图重新减少这种减少功能

function(key,values,rereduce){

 if(rereduce === true){

    //HELP HERE
    return results;
 } 


values.forEach(function(doc){

 if(results[(doc.id-1)]){
    results[(doc.id-1)].valori.push(doc.valore);
 }else{
    results[(doc.id-1)] = {
        id:doc.id,
        nome:doc.nome,
        unita:doc.unita,
        valori:[doc.valore]
    };  
 }
 });

return results;
}

有人可以帮我减少这个吗？

这是我的地图输出数据

[2015, 7, 6, 0, 0, 26] ID: bfc53ce117b53ec023c528e0c3039fc7 {nome: "COT ist.INGRESSO ", valore: 309.6, id: 1, unita: "mg/Nm", ora: "00:00:26"} [2015, 7, 6, 0, 0, 26] ID: bfc53ce117b53ec023c528e0c303a032 {nome: "COT ist.

等...

减少后我需要的是：

[{nome:"COT ist.Ingresso", id:1, unita:"mg/Nm",valori:[309.6,5.4,.....]}
{name:"thename",id:2, unita:"mg/Nm",valori:[6.8,3.5,......]}...]

这是一个4对象的数组（每个id一个），valori字段是各种valore字段的concat，（按键或ora属性排序）

CouchDB无法减少功能
