Adding accessor to usr sounds like a wise solution to hide test ifs, but it will mask the fact that avatar is accessor of person.

Hiding unneeded facts is what abstraction is all about. Why should a user of your backend model care about which table the avatar comes from? If the user doesn't have to care, it means you can change that stuff later on the in the database and only adapt your model, not your code that generates the HTML.

  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
