I need to make a JS variable equal to a MongoDB field, and as of now with the code I have, it is working, but not as intended. It is giving me a whole object, yet I only what the string value in which was assigned to the field. For example, you might have a document that contains the field
{name: "dylan"}
well I dont want all of that returned, I just want the string dylan. here is the code I have tried for my situation.
var game = SearchLobby.findOne( {profile: Meteor.userId()}, {game: 1,_id: 0} );

var game = SearchLobby.findOne( {profile: Meteor.userId()}, {game: 1,_id: 0} );
try this:
var name = SearchLobby.findOne( {profile: Meteor.userId()}).name;

var game = SearchLobby.findOne(
{profile: Meteor.userId()},
{game: 1,_id: 0}
).name;

2,772 Pointswhy did you change the variable name to "name"? disregard my example {name: "dylan"} if that is why you are doing that, sorry if I created the misconception that it is relevant, it was just supposed to be an example.

8,225 Pointsjust use the same principle that I pointed out in the example replacing with the field you want
if it is name, game or foo just use name, game or foo :)
var field = SearchLobby.findOne( {your query parameters here}).foo;
