How to set up Mongoose schema to store an array of objects in MongoDB?

I currently have an array that contains multiple objects nested inside of it.

Here is the format...

[ { id: 1, title: 'Squats', video: 'https://www.youtube.com/watch?v=aPYCiuiB4PA' }, { id: 2, title: 'Push-Ups',video: 'https://www.youtube.com/watch?v=aPYCiuiB4PA' }]

I am attempting to .save() it in my Schedule model that looks like this...

var ScheduleSchema = new mongoose.Schema({
    schedule: [Object]
})

When I run the following code in the Schedule controller on the server side, the .save() function gives me a 'success' message (that I programmed it to give), but when I look inside my MongoDB database, it saves incorrectly with nothing inside of the schedule array.

This is what the saved information looks like in the database....

{ "_id" : ObjectId("56c28a0d4c92bec03408c077"), "schedule" : [ ], "__v" : 0 }

I have a feeling my model is set up wrong.

Model schemas I have tried...

1) schedule: []
2) schedule: [Schema.Types.Mixed]

Just in case this is helpful, here is my .save() function when I try to save said data from the schedule controller...

var new_schedule = new Schedule(req.body.info);
new_schedule.save(function(err){
    if(err){
        console.log('err');
    }else{
        console.log('worked');
    }
})

  1. Make a model of inline objects in schema.

  2. Use this : 

    var model = mongoose.model("CollectionName",SchemaName);
model.insertMany(arrayOfSchedules , function(err,docs){});

I'd suggest setting up your schema like this:

var ScheduleSchema = new mongoose.Schema({
    schedule: [mongoose.Schema.Types.Mixed]
});

That would be the proper way to set it up. Another way to do it would be to define the object in-line, like this:

var ScheduleSchema = new mongoose.Schema({
    schedule: [{
        id: { type: Number, default: 1 },
        title: { type: String, default: '', trim: true },
        video: { type: String, default: '', trim: true }
    }]
});

Also, it may not be a problem on the server side code. Before you create the new Schedule with req.body.info, you might want to put in a line like this:

console.log(JSON.stringify(req.body, null, 2));

This will print out the req.body object in a readable format so that you can make sure the client app is sending the information you think you are getting.
