Meteor Simple-Schema Collection2 help needed for build nested schema - mongodb

Question

I am trying to build a collection schema with Meteor Collection2.
Possible schema for my collection is :
{
items: {
id: Meteor.ObjectID
title: String,
Desc: String,
createdAt: new Date(),
creator: String,
invitedUsers: [String],
items2: [{
id: String,
pos: Number,
dur: Number,
startTime: Number,
endTime: Number,
duration: Number
items3: [{
id: String,
itemtype: String,
style: String,
items4: [{
id: String,
position: Number,
dome: String
}]
}]
}]
}
}
So how can I best build the Collection2 collection with the above nested schema and the best way to perform insert, update and remove queries on it.
Update:
So now as suggested by Andrei Karpushonak this is what I have got:
Item4 = new SimpleSchema({
position: {
type: Number
},
dome: {
type: String
}
});
Item3 = new SimpleSchema({
itemtype: {
type: String
},
style: {
type: String
},
items4: {
type: [Item4]
}
});
Item2 = new SimpleSchema({
pos: {
type: Number
},
dur: {
type: Number
},
startTime: {
type: Number
},
endTime: {
type: Number
},
duration: {
type: Number
},
items3 : {
type: [Item3]
}
});
Items = new Meteor.Collection2('items', {
schema : new SimpleSchema({
title: {
type: String
},
Desc: {
type: String
},
createdAt: {
type: new Date()
},
creator: {
type: String
},
invitedUsers: {
type: [String]
},
items2: {
type: [Item2]
}
})
});
So now I am trying to figure out how can I do the insert, update, remove operations on such a schema?
Do I do for individual schemas for as whole? An example will be very helpful.
Any help will be highly appreciated.
Thanks in Advance,

Answer 1

You have two options:
Create sub-schema:
item2 = new SimpleSchema({
id: String,
pos: Number
})
item1 = new SimpleSchema({
id: Meteor.ObjectID,
title: String,
items2: [item2]
});
Use dot notation:
item1 = new SimpleSchema({
id: String,
pos: Number,
"item2.id": String,
"item2.pos": String
});
I think first approach fits your model better, as you have array of objects as value of items2
