To update a nested object in MongoDB using Mongoose, you can use the findOneAndUpdate method provided by Mongoose.
Here is an example of how you can update a nested object in a Mongoose model:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 |
const mongoose = require('mongoose');
// Create a Mongoose schema
const userSchema = new mongoose.Schema({
name: String,
address: {
street: String,
city: String,
state: String
}
});
// Create a Mongoose model
const User = mongoose.model('User', userSchema);
// Update a nested object in the database
User.findOneAndUpdate(
{ name: 'John' },
{ $set: { 'address.city': 'New York' }},
{ new: true }, // Return the modified document rather than the original
(err, user) => {
if (err) {
console.log(err);
} else {
console.log(user);
}
}
);

In this example, we are updating the city field of the address object for a user with the name 'John'. The $set operator is used to update the nested object. The new: true option tells Mongoose to return the modified document.
You can customize the update object according to your specific needs by using other Mongoose query operators such as $push, $pull, $inc, etc. to update nested objects in MongoDB using Mongoose.
