# I want a list of 6 non-administrators who are not the
# current user only if someone is logged in. Otherwise,
# don't check current_user's id.

# instead of this:

if user_signed_in?
  @other_users = User.non_admin.limit(6).where("name IS NOT NULL")
else
  @other_users = User.non_admin.limit(6).where(['id != ?', @user.id]).where("name IS NOT NULL")
