Tengo un shema de registro:

 const mongoose = require("mongoose"); const signupSchema = mongoose.Schema({ userId: { type: mongoose.Schema.Types.ObjectId, ref: "User", required: true }, cargoId: { type: mongoose.Schema.Types.ObjectId, ref: "Cargo", required: true }, truckIds: [{ truckId: {type: mongoose.Schema.Types.ObjectId, ref: "Truck", required: true } }], approved: { type: Boolean ,required: true }, finished: { type: Boolean ,required: true } }); module.exports = mongoose.model("Signup", signupSchema);

y controlador:

 exports.createSignup = (req, res, next) => { console.log(req.body.truckIds); const signup = new Signup({ userId: req.userData.userId, cargoId: req.body.cargoId, truckIds: req.body.truckIds, approved: req.body.approved, finished: req.body.finished, cmrCreated: false }); signup.save() .then(result => { res.status(201).json({ message: "Signup created!", result: result }); }) .catch(err => { res.status(500).json({ message: "DB error!" }); }); }

Quiero insertar datos en la colección para tener algo como esto:

 { "_id" : ObjectId("616d536c8e61e369ca82f2e4"), "userId" : ObjectId("60868c31caafe530e7e2d04a"), "cargoId" : ObjectId("614da0b0812a2f6169163d37"), "truckIds" : [id1,id2.....], "approved" : false, "finished" : false, "__v" : 0 }

No sé cómo insertar subdocumentos (truckIds) en una colección. Gracias de antemano.
