Is that the same error (undefined method `avatar' for nil:NilClass) or
a new one? If a new one then show us the full error message and the
line of code it relates to. If the same error then, as the previous
poster said, it is because @user is nil.

Also what is the code
unless: avatar.nil?
supposed to be doing? I see no code setting up a variable avatar.
