How to get all count of mongoose model?

How can I know the count of a model that data has been saved? there is a method of Model.count(), but it doesn't seem to work. var db = mongoose.connect('mongodb://localhost/myApp'); var userSchema = new Schema({name:String,password:String}); userModel =db.model('UserList',userSchema); var userCount = userModel.count('name'); userCount is an Object, which method called can get a real count? Thanks
