我正在尝试使用nodejs和mongoose从查询中获取子gruop。 我想要做的是以下内容: 我有这个系列:
我需要使用相同的'intent'对所有文档进行计数和分组,并创建一个具有'entity'值的子组,到目前为止,我已经运行了这个: 试试{
//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)
}
结果如下所示:
{
"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
}
]
}
我需要这样的结果:
{
"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
}
]
}
我希望明确,如果您知道如何使用mongoose,请告诉我。 提前谢谢。

尝试将第二个查询更改为以下
$push
如果您想要一个唯一的实体列表,可以使用{{1}}代替{{1}}
