问题
We have an angular project that we want to track User IDs with Google Analytics.
The problem is, when the user is logged out & first loads the site, we have the create call pass "auto"
ga('create', 'UA-XXXX-Y', 'auto');

When the user logs in, there is no page load. Is it a problem to call the "create" event again with the User ID, or is there a better way to do this?
ga('create', 'UA-XXXX-Y', { 'userId': 'USER_ID' });

You can use the set method if the user logs in after page load
ga('set', 'userId', 'USERID');
