That works. Thanks.
One other issue that's cropping up.
The STI inheiritance has some weird loading behavior. Writers are not
found with RegisteredUser.find until after they've been loaded with
Writer.find:
> RegisteredUser.find_by_name('John Doe')
=> nil
>> Writer.find_by_name('John Doe')
=> #<Writer id: 1, name: "John Doe">
>> RegisteredUser.find_by_name('John Doe')
=> #<Writer id: 1, name: "John Doe">
Any idea what that's all about?
