Is it possible to perform such operations in Mongo?

Question

MongoDB

Good afternoon, there are restaurants and categories. When adding a restaurant, the necessary categories are selected.
That is, the fields for the restaurant in this form

categories: [ { type: mongoose.Types.ObjectId, ref: "Category" } ]

And in this field there is a link to the category. However, when adding a category, I have exactly the same fields

const CategorySchema = new mongoose.Schema({
  name: { type: String, required: true, unique: true },
  slug: { type: String, required: true, unique: true },
  restaurants: [{ type: mongoose.Types.ObjectId , ref: "Restaurant" }]
})

However, the array of restaurants is empty, because the category is initially added and then the restaurant? The question is, is it somehow possible that when the category objectID is in the category array for a particular restaurant, that restaurant is in the restaurant array for the category.

I understand very well that MongoDB is not a real database, but I ask if this is possible using, for example, the same Middleware ?

Answer 1

Of course you can. Mongo is just designed to do this.
You understand everything perfectly, even with the help of the same Middleware.
