How to set schema for data structure in mongoose?

Question

Mongoose

I decided to try writing REST on express and mongoose. There is a certain json that describes the prices for medicines in different parts of the city, I can’t figure out how to correctly set a scheme for it so that in the future it can be served by the CRUD type.

{
    "region" : {
        "Алатауский район": [
            {
                "drugs_id": "sdfds5562606dsf",
                "max-price": 150,
                "min-price": 130,
                "date": "timestamp"
            }
        ],
        "Алмалинский район": [
            {
                "drugs_id": "sdfds5562606dsf",
                "max-price": 165,
                "min-price": 130,
                "date": "timestamp"
            }
        ]
    }
}

Do I need to create more entities?

I envisioned it like this:

const mongoose = require("mongoose")

const schema = mongoose.Schema({
  region_id: String,
  drug_id: String,
  max_price: Number,
  min_price: Number,
  date: Date
})

module.exports = mongoose.model("Data", schema)
