How can I update child objects in mongodb

Question

I want to store objects like this with mongodb: ``` { field: 'example', attr: { tmp : 'test', tmp1 : 'test1' } }; ``` Now I would like to search for the entry which has the property `field:'example'` and add a field to its `attr` object. How can I do this in mongojs?

Accepted Answer

You can add the `tmp2:'test2'` value into the collection as follows.

```
db.myObject.update({field:'example'},{$set:{'attr.tmp2':'test2'}})
```
