How to Fix: Mongoose, update values in array of objects
Learn how to fix: Mongoose, update values in array of objects.
📋 Table of Contents
Mongoose does not support updating values in an array of objects directly. The issue lies in the use of `$` with `items.$` which is a MongoDB operator, not Mongoose.
🛑 Root Causes of the Error
- The problem arises from using `$` operator with Mongoose, which is not designed to work with arrays.
✅ Best Solutions to Fix It
Method 1: Using the `updateMany` Method
- Step 1: Use the `$` operator with the array index, not the object.
Method 2: Using a Loop to Update Individual Objects
- Step 1: Iterate over the array and update each object individually using `updateOne` method.
🎯 Final Words
To successfully update values in an array of objects, use the `$` operator correctly or iterate over the array using Mongoose's `updateMany` and `updateOne` methods.
