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!
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!
@@bekiteshome4670 it depends if you are new to the field, it would take at least six months for you to learn frontend and fundamentals of backend + some projects on both frontend and backend
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.

I am still a begginner at this so I might be wrong, if so please someone correct me: But I believe, for instance you want to keep address of authors if you keep the author as an nested document it would mean you can have 2 (or more] "Terry Pretchett" with diferent addresses in different books, if you would want to make sure there is only one Terry Pretchett you would need to separate Authors to a different collection and reference by ID
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?
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.

Hey Shaun, It would be great If you add videos about complex queries and relation strategies.

is it hard being full stack developer?
@@bekiteshome4670 not hard, but definitely would take time
@@aliwarraich5067 how much time does it take yours to become full stack dev.

@@bekiteshome4670 for me, its been two years since I first started learning web but I didn't learn all the stack together because of my studies
Thank you 😊

you can try this
db.books.updateOne({_id:ObjectId("639be6ae4d7ef7d4b96b8cc7")}, {$pull: {genres: {$in: ["1","2"]}}})
@@a0955383566thanks. It worked. Is that the new update? In instead of each?
I also tried doing that, I thought it was going to work.
try using $in instead of $each
Thank you very much.
great stuff man!!!

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

Need mysql tutorials
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 😅
You have used a constant value 8 to update ratings field, but can we code like this segment to update the same value....{rating: rating-1}...??
