Currently I have an array object that contains the following structure
{
"ID_Local_leitura": "2134236478dysa743242579f",
"idO": "11342s36478dysa743242579",
"timeStamp": "2016-11-11T02:00:00.000Z",
"quantidadeAnimais": 50,
"tipoDeAnimal": "Corte ",
"quantidadeProduto": "Nível 0",
"sacosProduto": 1,
"idProduto": "11342136448dyty43242579",
"loteProduto": "1513/16G",
"imagem": "/imgs/foto1432543583123.jpeg",
"categoria": "Categoria 3",
"resp": "leitura",
"_id": "33065027c0a359d395238fd76787b3fc",
"_rev": "2-33065027c0a359d395238fd76787b3fc",
"peso": 30,
"resultado": 0.6
}
I'm currently using Underscore.js
to group this array, method below.
function filtro(filtrar) {
var notNull = _.negate(_.isNull);
var groups = _.groupBy(relatorioData.leituras, function(note){
return _.find(_.pick(note, filtrar), notNull);
});
The above method works perfectly for grouping using only 1 JSON attribute, I was wondering if there is how to group by more than 1 attribute using Underscore. If there are alternatives to underscore for this case please let me know.
For example I want to group everything that has ID_Local_leitura
, timeStamp
, categoria
and idProduto
as the same value into a new array of objects, in my searches I found only the ordering by multiple values using underscore.
