Well, you might be able to do:
@scaffold_browse_fields = [:username, :user_roles]
def user_roles
# do query, return string
end
That's going to do a separate query per row though. I don't believe
scaffolding extensions offers the ability to customize the query used in a
manner similar to what you want.
Thanks,
