#78 Limiting fields | Using MongoDB with Express| A Complete NODE JS Course

In this lecture you will learn how to limit only certain fields in the result so that you can avoid sending sensitive data over the wire. And this is also a good practice to allow users to select which fields user wants in the result and avoid overwhelming the network bandwidth.

10:40 In Mongoose 8.x.x You can mix between inclusion and exclusion fields

[@Tech_bro-i5g]

Please sir! if you can help. People are encountering a common issue with the sort and limit logics, i inclusive. The both of them are returning null, empty array, when we run it in postman.

I am using the mongoose 8.0.3 version , will req.query.sort or req.query.fields ..will work ..as I am not getting the desired results

[@Tech_bro-i5g]

@@Tech_bro-i5g i explained the solve in comments of this and previous video add this line of codes: delete queryObj.sort delete queryObj.fields before the "let query = Movie.find(queryObj) " Because mongoose trying to fetch the documents that match with the parameters entered the query string, in that case it can't find anything and returns null
