To update a nested object in MongoDB, you can use the dot notation to access and update the specific field within the nested object. Here is an example using the MongoDB update method:

  1. Find the document containing the nested object that you want to update:
1
db.collection_name.find({ "nestedObject.field": "value" })


  1. Update the nested object using the $set operator and the dot notation to specify the field within the nested object:
1
2
3
4
db.collection_name.update(
  { "nestedObject.field": "value" },
  { $set: { "nestedObject.fieldToUpdate": "newValue" } }
)


This will update the field within the nested object in the document that matches the specified query. Make sure to replace collection_name, nestedObject.field, value, fieldToUpdate, and newValue with your actual collection name, nested field path, query value, field to update, and new value, respectively.
