I wrote the below code

    def clear_aggregates(r, **attr):
        if (not s3_has_role(ADMIN)):
            auth.permission.fail()
        s3db.stats_demographic_rebuild_all_aggregates()
        redirect(URL(c='stats', f='demographic_aggregate', args=''))
    s3db.set_method('stats', 'demographic_aggregate', method='clear', action=clear_aggregates)
    output = s3_rest_controller()
    return output

What's a good function header?
