Updating a specific element in an array with MongoDB / Meteor
meteor, mongodb
Solution
You can't use variables as keys in an object literal. Give this a try:
var obj = {};
obj["users_voted." + index] = u_object;
Posts.update({_id: post_id}, {$set: obj});
Problem
``` "users_voted" : [ { "user_id" : "AQG8ECLdBRJ4jwPMG", "score" : "down" } ] ``` Wondering how I would go about updating the `users_voted` field which is an array objects. I need to have a specific object updated. I know the `index` at which this object is located, I simply need to figure out how I can update that object in a MongoDB / Meteor collection. This is some pseudo-code that I have to better explain what I mean. `Posts.update({_id: post_id}, {$set: {vote_score[index]: u_object}});` So in this query I know `index` and `post_id` as well as `u_object` is the object that I am trying to put into the array in place of whatever object that was there at that `index`. If someone could help let me know how I should go about this, it would be great.
