If not using the form_for/tabular_form_for to display errors - this is a way to cleanly display the first error. Putting the li tags will make it appear like the standard rails form_for generated error list. <%= error_message_on(@account, "owner_id", "<li>", "</li>", "error_message") %> # returns: <div class="error_message"><li>can't be blank</li></div>"
