Complete MongoDB Tutorial #14 - Updating Documents

I have a question, I'm new to MongoDb and I came across a situation which is the following. Using your books collection as an example, how would you update a property of your nested array of reviews, let's say you would like to updated the "body" of the first review on for your "The Color of Magic" book , I can't figure how would you do that.

Such a clear tutorial on updating MongoDB Documents. Thank you, Shaun.

if only my CST-345 class referenced this series as the curriculum for MongoDB! I could not figure out how to use the shell for MongoDB based on their instructions. Thank you!

The push and pull operators (with the each) were right on the money!

Thanks a lot mate, saved me a day or two over here 😅

👍👍👍

There's an error when pulling with $each: MongoServerError: unknown top level operator: $each. If you have a field name that starts with a '$' symbol, consider using $getField or $setField.
I simply replaced the $push operator to $pull. Does $each only work for $push?

God bless you sensei 🙇‍♂️🙏

If you want to pull these values back out:
db.books.updateOne({ _id: ObjectId("630e45de45c09161952d2db5") }, {$pull: {genres: {$in: ["2", "1"]}}})

You're my favourite go-to tutorial!

good presentation of practical skills

Is there a scenario with MongoDB or NOSQL in general where you would still use a lookup table? Thinking in this example where we would have a separate lookup table with authors. Then the "author" value would be a reference to the Author Lookup Table's unique ID.

After mongodb is there a chance for you to make mariadb? I am so used to your tutorials that it can help me very much seeing it from you :D

This series couldn't have come at a better time, as I'm looking to start working on a large project and leaning towards the MERN stack. Cheers Shaun, great content and easy to follow, as always!
