Pushing object to a subcollection array

General
1
  1. My goal is: pushing an object which is created by user via form to an subcollection that is also created by the user.
  2. My actions are: I’ve created subcollection(named “category”) endpoint and list them in the form which user can create object(named “product”) and pick a category .But i couldnt achieve to post endpoint for adding a product under the selected category.
    My Models:

const mongoose = require(“mongoose”);

const menuSchema = mongoose.Schema({
company: { type: mongoose.Schema.Types.ObjectId, ref: “Company” },

category: [
{
name: String,
products: [
{
name: String,
price: Number,
description: String,
state: Boolean,
imgUrl: String
}
]
}
]
});

module.exports = mongoose.model(“Menu”, menuSchema);

const mongoose = require(“mongoose”);

const companySchema = mongoose.Schema({
companyName: String,
email: String,
password: String,
adress: String,
Phone: Number,
contractNo: String,
menu: [
{
type: mongoose.Schema.Types.ObjectId,
ref: “Menu”,
category: [{ type: mongoose.Schema.Types.ObjectId, ref: “Menu” }]
}
],
createdAt: { type: Date, default: Date.now() }
});

module.exports = mongoose.model(“Company”, companySchema);

EndPoint for adding product that i couldnt get successful result

AddProduct(req, res) {
const body = {
name: req.body.name,
price: req.body.price,
description: req.body.description,
imageUrl: req.body.image,
state: req.body.state
};

Menu.find({ company: req.company._id }, (err, founds) => {
  const CatId = req.body.category;

  const data = founds[0].category;

  for (let i = 0; i < data.length; i++) {
    if (data[i]._id == CatId) {
      console.log(CatId);
      Menu.update(
        { products: data[i].products },
        { $push: { products: body } },
        { new: true }
      )
        .then(info => {
          res.status(httpStatus.CREATED).json({ message: "created", info });
          console.log(info);
        })
        .catch(err => {
          res
            .status(httpStatus.INTERNAL_SERVER_ERROR)
            .json({ message: "add-product error", err });
        });
    }
  }
});

},

  1. The result I see is: 1. {message: “created”, info: {…}}

  2. info:

1. n: 0
2. nModified: 0
3. ok: 0
4. __proto__: Object
  1. message: “created”
  2. proto: Object
  3. My expectation & question is: How can i code an endpoint to push a product object to under selected category by user.
