mongo object references in mongoose

Certainly! Here's an example of how you might create object references in MongoDB using Go and Mongoose:

  1. Define the Schemas: ``go type Author struct { ID primitive.ObjectIDbson:"_id,omitempty"Name stringbson:"name"Books []primitive.ObjectIDbson:"books,omitempty"` }

type Book struct { ID primitive.ObjectID bson:"_id,omitempty" Title string bson:"title" Author primitive.ObjectID bson:"author,omitempty" } ```

  1. Create the References: go author := Author{ Name: "J.K. Rowling", } book := Book{ Title: "Harry Potter and the Sorcerer's Stone", Author: author.ID, }

  2. Save the Data: ```go // Save author _, err := collection.InsertOne(context.Background(), author) if err != nil { log.Fatal(err) }

// Save book _, err = collection.InsertOne(context.Background(), book) if err != nil { log.Fatal(err) } ```

  1. Fetch Data with References: ```go var fetchedBook Book err = collection.FindOne(context.Background(), bson.M{"title": "Harry Potter and the Sorcerer's Stone"}).Decode(&fetchedBook) if err != nil { log.Fatal(err) }

var fetchedAuthor Author err = collection.FindOne(context.Background(), bson.M{"_id": fetchedBook.Author}).Decode(&fetchedAuthor) if err != nil { log.Fatal(err) } ```

This example demonstrates the creation of object references between an Author and a Book using MongoDB in Go.
