How do relations work in MeteorJS/Mongodb? - mongodb

Question

and am not sure where to find this in the docs. How can I add more objects to the User object?
For instance if I run
meteor add accounts
and I get a full user collection with a working user login/signup template. I would like to add a posts collection/object inside this users collection, so that users can only view there own posts.
So how can I add each post to the current users object?

Answer 1

You can add users to the Meteor.users collection by adding accounts-password package. Use Accounts.createUser() method to create new users.
Find the documentation here: https://docs.meteor.com/api/passwords.html#Accounts-createUser

Answer 2

Meteor.users is a handle to users collection in Meteor. You can use it just as any other collection AKA
Meteor.users.findOne(id)
or
Meteor.users.update(...)
And of course you can't add posts collection to user collection. These will be different collections.
Storing objects in MongoDB under users collection document is pretty straight forward:
Meteor.users.update(
{ _id: userId },
{ $set: { objectFieldName: { a: 1, b: 2 }}}
)
Or if you need to do it on user create you should user Accounts package hooks.

Answer 3

You are approaching it wrong. Use pub/subs to achieve this.
When you insert a post, have a field called userId or ownerId
//inside Meteor.methods() on server side
Posts.insert({
owner: Meteor.userId(),
//some other fields
});
Then in your publication, return only the Posts that the user owns
//publication on server side
//checks if the visitor is a user
//if user, returns that user's posts
Meteor.publish('posts', function() {
if (this.userId) {
return Posts.find({owner: this.userId})
}
});
Then subscribe to the publication. No parameters needed:
//client side
Meteor.subscribe('posts')
