Thanks, Orlando! This seems to be causing a problem with code I have in `app/controllers/static_pages_controller.rb` (as best I can tell). I have this there:

    class StaticPagesController < ApplicationController
        def home
            @groups = Group.all
            @categories = @groups.select("DISTINCT(CATEGORY)")
        end
    end

When I call `@categories` in my view, `self.email = user.email` raises the error `missing attribute: user_id`. Any ideas?
