how possible retrieve particular element in array string? have populated field called 'list' consist of document id's posts collection.

the postid's inserted in next manner within method:

var postid = //code retrieving post id meteor.users.update( this.userid, { $addtoset: { 'profile.list': postid}});

now, retrieve first postid value find post document.

var postid = meteor.user().profile.list; posts.update( {_id: postid}, { $addtoset: {'message': sometext}});

the update not work appears in console log retrieving object [ 'svnjazwnfw8fpobjv' ] - not string. if manually insert postid value enclosed speech marks, work.

how can target specific position of 'list' field , utilize value perform update?

if want update individual postid::

// index position in list want update (0 first one) posts.update( {_id: postid[index]}, { $addtoset: {'message': sometext}});

if wanted update whole lot:

posts.update( {_id: { $in: postid }}, { $addtoset: {'message': sometext}});
