How to insert an object in an array using Mongo shell commands?

Question

I have to insert an object {"category" : "Vehicle"} in the rated array below using Mongo shell commands. How can I do that?

 {
     "rating": {
         "userid": 1234,
         "bookingid": 4567,
         "rated": [
             {
                 "_id": "5aaa356f6b992b2068a1b691",
                 "category": "Driver",
                 "comment": "Good",
                 "rating": 5
             },
             {
                 "_id": "5aaa356f6b992b2068a1b690",
                 "category": "Overall",
                 "rating": 7
             }
         ]
     },
     "_id": "5aaa356f6b992b2068a1b68f",
     "__v": 0 }

It's quite simple. Use $push method to push an object into an array.

db.ratings.update(
   { _id: ObjectId('5aaa356f6b992b2068a1b68f') },
   { $push: { rated: {"category" : "Vehicle"} } }
)

Here, ratings is the collection name.

This will insert an object into the rated array.

db.collection.update({

    }, {
        $addToSet: {
            'rating.rated': {
                "category": "Vehicle"
            }
        }
    }
