Retrieve data from an array within the user Collection using Meteor and React Native

I need assistance with retrieving the entire array [votes] stored within the User Collection. Below is the JSON structure

{
    "_id" : "pziqjwGCd2QnNWJjX",
    "createdAt" : ISODate("2017-12-21T22:06:41.930Z"),
    "emails" : [ 
        {
            "address" : "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="483c2d3b3c083c2d3b3c662b2725">[email protected]</a>",
            "verified" : false
        }
    ]
    "votes" : [ 
        {
            "ZyYZ4LDTaeWNMN9eE" : "yes"
        },
        {
            "DSHhkdsjkdhsddsqd" : "no"
        }
    ]
}

Could someone provide guidance on how to display that array using console.log? I want to verify its existence before proceeding with an insertion operation.

Answer №1

To simply verify the presence of an array with elements:

const userInfo = Meteor.users.findOne(userID);
const hasInteractions = userInfo && userInfo.interactions && typeof(userInfo.interactions) === 'object' && userInfo.interactions.length;

Answer №2

In the scenario where you are retrieving a single document from a MongoDB collection, follow this code:

var user = Users.findOne({_id: your_given_id});

if(user && user.votes && user.votes.length){
    console.log(user.votes);
    return user.votes;
}
console.log('No Votes Found.');
return [];
