Najlepszy sposób na dodanie dynamicznej siatki jako danych wejściowych w niestandardowym rozszerzeniu Adminhtml

Zbudowałem niestandardowe rozszerzenie lokalizatora sklepu z jego własną siatką i edytuję strony w Adminhtml i wszystko działa świetnie. W przypadku godzin otwarcia sklepów chciałbym wdrożyć dynamiczną siatkę, tak jak w przypadku opcji atrybutów.

Teraz znalazłem rozwiązanie, ale mam nadzieję, że istnieje lepszy, a przynajmniej czystszy sposób. Do tej pory dodałem renderer do pola w formularzufieldset

class Redkiwi_Rkstorelocator_Block_Adminhtml_Rkstorelocator_Edit_Tab_General extends Mage_Adminhtml_Block_Widget_Form
{
    protected function _prepareForm()
    {
        $form = new Varien_Data_Form();
        $this->setForm($form);
        $fieldset = $form->addFieldset('rkstorelocator_form', array('legend'=>Mage::helper('rkstorelocator')->__('Store information')));

        [...]

        $officehours_field = $fieldset->addField('office_hours', 'editor', array(
            'name'      => 'office_hours',
            'label'     => Mage::helper('rkstorelocator')->__('Office hours'),
            'required'  => false,
        ));

        $officehours_block = $this->getLayout()
                                ->createBlock('rkstorelocator/adminhtml_rkstorelocator_edit_renderer_officehours')
                                ->setData(array(
                                    'name'      => 'office_hours',
                                    'label'     => Mage::helper('rkstorelocator')->__('Office hours'),
                                    'required'  => false,
                                ));

        $officehours_field->setRenderer($officehours_block);

        [...]
    }
}

I klasa bloków do renderowania

class Redkiwi_Rkstorelocator_Block_Adminhtml_Rkstorelocator_Edit_Renderer_Officehours
 extends Mage_Adminhtml_Block_Abstract 
 implements Varien_Data_Form_Element_Renderer_Interface 
{

    public function render(Varien_Data_Form_Element_Abstract $element) 
    {
        $required_indicator = $this->getData('required') ? '<span class="required">*</span>' : '' ;

        $html = '
<table id="attribute-options-table" class="dynamic-grid rkstorelocator-officehours" cellspacing="0" cellpadding="0"><tbody>
    <tr>
        <th>Day indicator</th>

        <th>Closing hour</th>
        <th>
            <button id="add_new_option_button" title="Add Option" type="button" class="scalable add"><span><span><span>Add Option</span></span></span></button>
        </th>
    </tr>
</tbody></table>

<script type="text/javascript">//<![CDATA[

var _form_html_row = \'<tr class="option-row rkstorelocator-officehours-dayrow" id="hour-row-{{id}}"><td><input name="'.$this->getData('name').'[value][option_{{id}}][0]" value="" class="input-text required-option" type="text"></td><td><input name="'.$this->getData('name').'[value][option_{{id}}][2]" value="" class="input-text required-option" type="text"></td><td><input name="'.$this->getData('name').'[value][option_{{id}}][2]" value="" class="input-text required-option" type="text"></td><td class="a-left" id="delete_button_container_option_{{id}}"><input type="hidden" class="delete-flag" name="'.$this->getData('name').'[delete][option_{{id}}]" value=""/><button onclick="$(\\\'hour-row-{{id}}\\\').remove();" title="Delete" type="button" class="scalable delete delete-option"><span><span><span>Delete</span></span></span></button></td></tr>\';

var _rkstorelocator_counter = 0;

$(\'add_new_option_button\').on(\'click\', \'button\', function(){
    $(\'attribute-options-table\').insert(_form_html_row.replace(/\{\{id\}\}/ig, _rkstorelocator_counter));
    _rkstorelocator_counter++;
});

//]]></script>
        ';
        return $html;
    }

}

Co daje mi następujący wynik

Teraz to w zasadzie działa, ale uzyskanie obecnych wartości będzie dość niechlujne i w sumie nie jestem zbyt dumny z kodu, który napisałem (jak można sobie wyobrazić).

Poszukałem kilku rozwiązań, ale ogólnie wszystkie przyjmują takie podejście. Czy ktoś zna czystszy sposób to zrobić?

Długo mi zajęło uświadomienie sobie, że ceny Tier wyglądają tak, jak chcę. Więc po sprawdzeniu, jak Magento robi to z wyceną Tier, skończyłem, wykonując następujące czynności. Z góry przepraszam za ogromne bloki kodu, ale pomyślałem, że może być interesujący w przyszłości.
