Guide to extracting the value of an attribute from a Meteor collection object

In my database, I have a collection called Meteor.users. Each user in this collection has an attribute named “lastQuestionAnswered”, which stores the questionId of the last question they answered.

{ "_id" : "jrCJiuo7eprNFKfLG",
"name" : "Elon Musk",
"lastQuestionAnswered" : 1 }

I need to figure out how to retrieve the value of the lastQuestionAnswered attribute for the current user and store it in a variable. The goal is to have

Var lastAnsweredQuestionId = ???

I am attempting to do this on the server-side. I have researched similar questions but haven't found any helpful clues. Any assistance you can provide would be greatly appreciated. Thank you in advance.

Answer №1

To retrieve the current user on the client side, utilize the Meteor.user() method. Modify your code as follows:

var lastAnsweredQuestionId = Meteor.user().lastQuestionAnswered;

This code snippet will function on the client side or within server side methods (if the user is authenticated).

UPDATE

If you wish to achieve the same outcome in a publish function, you must approach it differently as the Meteor.user() method is not compatible with publishers:

var currentUser = Meteor.users.findOne({_id: this.userId});
var lastAnsweredQuestionId = currentUser.lastQuestionAnswered;
