Sure it does, if by direct you mean has to go through a client library.

If we throw out the method and apply what the method does then:
Sure I do, unless... I go ***through*** the same library that ActiveRecord does.

Sure they shouldn't because `@user = User.where(:id => session[:uid])`
in the controller isn't how most programmers go about it, most of them
decorate it all into neat and tidy formatted objects that create
completely indirect access. An instance of an object in a variable
set inside of the controller and accessible in the view is not an
indirect access. But maybe you meant to say you should never
initialize that object in the view as it's the views job to transform
that object into something meaningful not to pull that data into that
object and all the other things we go on about.
