@user = @question.user
but in fact there is no need to do that in the controller. In the
view just use @question.user.name or whatever it is. That assumes
that every question will have a user, if there is any chance that a
question will not have a user then @question.user.name would fail as
user would be nil, so you would have to cope with that.

Since you are asking the question I suggest that you work through a
good tutorial which would give the basics of rails. railstutorial.org
is good and is free to use online.
