Pushing Array of Objects Mongoose NodeJS - node.js

Question

I have a mongoose schema defined as such,
var userSchema = mongoose.Schema({
token: String,
school: [{name: String, grade: String}]
});
As you can see it is "school" with two values of strings inside it.
I am trying to push in values like this,
app.post('/array', function(req, res) {
user.find({
token: "c30a2402dcd8e4580cef8177516e8c57149425bf961a254fd79cf7b7280a6af0adf620d210c8b66989fe7fd35a3adc2756ec2089b415d27c1a1c097e88bc4666"
}, function(err, users) {
if (users.length != 0) {
user.findOne({
token: "c30a2402dcd8e4580cef8177516e8c57149425bf961a254fd79cf7b7280a6af0adf620d210c8b66989fe7fd35a3adc2756ec2089b415d27c1a1c097e88bc4666"
}, function(err, doc) {
doc.ar.push("sss", "A");
doc.save();
});
} else {}
});
});
But the push does not work and gives me an error that I cannot get rid of.
doc.ar.push({"sss","A"});

Is there a way to easily push values in?

Answer 1

That's a simple JavaScript syntax error. You probably want this:
doc.ar.push({name: "sss", grade: "A"});
