Insert with Nested Documents in MongoDB

📖 Scenario: You are managing a small library database. Each book has a title, author, and details about its publisher. The publisher information includes the name and address, which is a nested document.

🎯 Goal: Create a MongoDB document for a book that includes nested publisher details, and insert it into the books collection.

💡 Why This Matters

🌍 Real World

Nested documents are common in MongoDB to represent related data in one place, like a book and its publisher.

💼 Career

Understanding nested documents and insert operations is essential for working with MongoDB in real-world applications.

1

Create the book document

Create a variable called book that holds a document with title set to "The Great Gatsby" and author set to "F. Scott Fitzgerald".

MongoDB

# Your code here

Need a hint?

Use curly braces to create a document. Add title and author as keys with their values.

2

Add nested publisher document

Add a publisher field to the book document. This field should be a nested document with name set to "Scribner" and address set to "123 Publisher St".

MongoDB

book = {
    "title": "The Great Gatsby",
    "author": "F. Scott Fitzgerald"
}
# Add the nested publisher document here

Need a hint?

Inside the book dictionary, add a key publisher with another dictionary as its value.

3

Insert the document into the collection

Use db.books.insertOne(book) to insert the book document into the books collection.

MongoDB

book = {
    "title": "The Great Gatsby",
    "author": "F. Scott Fitzgerald",
    "publisher": {
        "name": "Scribner",
        "address": "123 Publisher St"
    }
}
# Insert the book document into the books collection

Need a hint?

Use the insertOne method on the books collection to add the document.

4

Verify the insertion with a query

Write a query using db.books.findOne({"title": "The Great Gatsby"}) to retrieve the inserted document.

MongoDB

book = {
    "title": "The Great Gatsby",
    "author": "F. Scott Fitzgerald",
    "publisher": {
        "name": "Scribner",
        "address": "123 Publisher St"
    }
}
db.books.insertOne(book)
# Query to find the inserted book document

Need a hint?

Use findOne with a filter on title to get the document.
