Meteor: add extra data to user on social sign up

Question

In Meteor, I'd like to add a referrer field to new user signups. I can do this for users that register with a password, by passing in extra options to be used with Accounts.onCreateUser(function (options, user).

But this doesn't seem to work with social login. Any ideas how I can get this working?

Answer 1

I think I had a similar issue, and ended doing something like

• create the user without the field you would like to pass as an option
• ask the client for the value of that field
• update the user

So:

//server
Accounts.onCreateUser(function(options, user) {
  if (user.services.facebook)
    user.askReferer = true;
  retur user;
});

//client
var userId;
Tracker.autorun(function() {
  var user = Meteor.user();
  if (!user || user.id === userId || !user.askReferer) {return;}
  userId = user.id;
  var referer = ...;
  Users.update({_id: user.id}, {$set: {referer: referer}}, {$unset: {askReferer: 1}});
});

Would love if someone comes up with a better solution!
