Supplies.find({ clientID })
.populate({
path: "products",
model: "products",
select: "title"
})
.populate("supplier", "name")
我有此查询可返回耗材,我想在产品上填充,收到的第一个文档为true,但是第二个文档不能在产品ID上填充,因为产品ID不在Product._id中,而在Product中。 options._id 选项是一系列文档。
如何在选项数组中以及没有选项数组时填充所有文档 .....
[{
"_id": "5c2b736fd550e230dc317c7f",
"product": {
"_id": "5c23812970bebe20f143c0a2",
"title": "Iphone 6S"
},
"quantity": 2
"supplier": {
"_id": "5c0d18447e0f436d5cbb110a",
"name": "blabla bla"
}
},
{
"_id": "5c2b7387d550e230dc317c80",
"product": "5c23847a217c5521f8b3fd78",
"quantity": 4,
"supplier": {
"_id": "5c0d18447e0f436d5cbb110a",
"name": "bla bla"
}
}]
这是产品型号
const ProductSchema = new mongoose.Schema({
title: { type: String, required: true },
options: [
{
title: { type: String, required: true }
}]
});
