$user = User::with('subscription')->where('id', '=', 123)->first();

If I then later try and do something like this:

$user->firstname = 'John';

I get an SQL error because it says that there is no DB field called "subscription" It seems like the relationship is being treated as a DB field when saving. Is that right? Am I mean to
