我想從使用nodejs和貓鼬的查詢中得到一個子組。 我想要做的事是： 我有這個集合： 
子組Mongoose
我需要統計和組都具有相同的「意圖」的文件，並進行分組與「實體「值，到目前爲止，我有這個運行： 嘗試{
//We first get the total interactions from all workspace
let workspace = await Interaction.aggregate([
{ $match: { dateAdded: { $gte: todayStart, $lt: todayEnd }, workspace: workspaceID } },
{ $group: { _id: "$workspace", data: { $sum: 1 } } },
{ $sort: { _id: 1 } }
]).exec();
//We then get the total results from conversations
let results = await Interaction.aggregate([
{ $match: { dateAdded: { $gte: todayStart, $lt: todayEnd }, workspace: workspaceID } },
{ $group: { _id: '$intent', data: { $sum: 1 } } },
{ $sort: { _id: 1 } }
]).exec()
//workspaceItems = workspace.map(function (Interaction) { return Interaction._id; });
return res.json({
total: workspace,
result: results
})
} catch (err) {
console.log(err);
return res.status(500).send(err)
}
結果是這樣的：
{
"total": [
{
"_id": "Business",
"data": 23
}
],
"result": [
{
"_id": "N/A",
"data": 2
},
{
"_id": "PRODUCTO_BENEFICIOS",
"data": 3
},
{
"_id": "PRODUCTO_DESCRIPCION",
"data": 10
},
{
"_id": "REPORTE_TARJETA_PERDIDA",
"data": 1
},
{
"_id": "REQUISITOS",
"data": 7
}
]
}
我需要的結果是這樣的：
{
"total": [
{
"_id": "Business",
"data": 23
}
],
"result": [
{
"_id": "N/A",
"data": 2
},
{
"_id": "PRODUCTO_BENEFICIOS",
"entities: [{"TARJETAS","PROMOCIONES"."ETC..."}],
"data": 3
},
{
"_id": "PRODUCTO_DESCRIPCION",
"entities: [{"TARJETAS","PROMOCIONES"."ETC..."}],
"data": 10
},
{
"_id": "REPORTE_TARJETA_PERDIDA",
"entities: [{"TARJETAS","PROMOCIONES"."ETC..."}],
"data": 1
},
{
"_id": "REQUISITOS",
"entities: [{"TARJETAS","PROMOCIONES"."ETC..."}],
"data": 7
}
]
}
我希望是明確的，請讓我知道如果你知道如何使用貓鼬做到這一點。 預先感謝您。
