Risposte:
Preparati, questo sarà lungo. Ecco qui.
Avrai bisogno dei seguenti file:
app/code/local/[Namespace]/[Module]/Block/Adminhtml/[Entity]/Edit/Tab/Categories.php
- la scheda che renderà le categorie.

<?php endif; ?>
Nel file del modulo in cui aggiungi le schede dell'entità personalizzata aggiungi anche questo:
$this->addTab('categories', array(
'label' => Mage::helper('[module]')->__('Associated categories'),
'url' => $this->getUrl('*/*/categories', array('_current' => true)),
'class' => 'ajax'
));
Nel controller di amministrazione dell'entità personalizzata queste 2 azioni che gestiranno le richieste per le categorie:
public function categoriesAction(){
$this->_init[Entity]();
$this->loadLayout();
$this->renderLayout();
}
public function categoriesJsonAction(){
$this->_init[Entity]();
$this->getResponse()->setBody(
$this->getLayout()->createBlock('[module]/adminhtml_[entity]_edit_tab_categories')
->getCategoryChildrenJson($this->getRequest()->getParam('category'))
);
}
e assicurati che nello stesso controller esista questo metodo:
protected function _init[Entity](){
$[entity]Id = (int) $this->getRequest()->getParam('id');
$[enity] = Mage::getModel('[module]/[entity]');
if ($[entity]Id) {
$[entity]->load($[entity]Id);
}
Mage::register('current_[entity]', $[entity]);
return $[entity];
}
Nel file di layout dell'amministratore del modulo aggiungere questo handle per l'azione delle categorie:
<adminhtml_[module]_[entity]_categories>
<block type="core/text_list" name="root" output="toHtml">
<block type="[module]/adminhtml_[entity]_edit_tab_categories" name="[entity].edit.tab.categories"/>
</block>
</adminhtml_[module]_[entity]_categories>
Ora procediamo al salvataggio dei tuoi dati.
Per questo è necessario quanto segue in uno degli script di installazione / aggiornamento del modulo. Ciò creerà una tabella in cui verranno memorizzati i valori collegati
$table = $this->getConnection()
->newTable($this->getTable('[module]/[entity]_category'))
->addColumn('rel_id', Varien_Db_Ddl_Table::TYPE_INTEGER, null, array(
'unsigned' => true,
'identity' => true,
'nullable' => false,
'primary' => true,
), 'Relation ID')
->addColumn('[entity]_id', Varien_Db_Ddl_Table::TYPE_INTEGER, null, array(
'unsigned' => true,
'nullable' => false,
'default' => '0',
), '[Entity] ID')
->addColumn('category_id', Varien_Db_Ddl_Table::TYPE_INTEGER, null, array(
'unsigned' => true,
'nullable' => false,
'default' => '0',
), 'Category ID')
->addColumn('position', Varien_Db_Ddl_Table::TYPE_INTEGER, null, array(
'nullable' => false,
'default' => '0',
), 'Position')
->addIndex($this->getIdxName('[module]/[entity]_category', array('category_id')), array('category_id'))
->addForeignKey($this->getFkName('[module]/[entity]_category', '[entity]_id', '[module]/[entity]', 'entity_id'), '[entity]_id', $this->getTable('[module]/[entity]'), 'entity_id', Varien_Db_Ddl_Table::ACTION_CASCADE, Varien_Db_Ddl_Table::ACTION_CASCADE)
->addForeignKey($this->getFkName('[module]/[entity]_category', 'category_id', 'catalog/category', 'entity_id'), 'category_id', $this->getTable('catalog/category'), 'entity_id', Varien_Db_Ddl_Table::ACTION_CASCADE, Varien_Db_Ddl_Table::ACTION_CASCADE)
->addIndex(
$this->getIdxName(
'[module]/[entity]_category',
array('[entity]_id', 'category_id'),
Varien_Db_Adapter_Interface::INDEX_TYPE_UNIQUE
),
array('[entity]_id', 'category_id'),
array('type' => Varien_Db_Adapter_Interface::INDEX_TYPE_UNIQUE))
->setComment('[Entity] to Category Linkage Table');
$this->getConnection()->createTable($table);
Dichiara il tuo tavolo. Aggiungi questo config.xml
all'interno del <[module]_resource><entities>
tag
<[entity]_category>
<table>[module]_[entity]_category</table>
</[entity]_category>
Sarà necessario un modello per il collegamento a categorie:
app/code/local/[Namespace]/[Module]/Model/[Entity]/Category.php
<?php
class [Namespace]_[Module]_Model_[Entity]_Category
extends Mage_Core_Model_Abstract {
protected function _construct(){
$this->_init('[module]/[entity]_category');
}
public function save[Entity]Relation($[entity]){
$data = $[entity]->getCategoriesData();
if (!is_null($data)) {
$this->_getResource()->save[Entity]Relation($[entity], $data);
}
return $this;
}
public function getCategoryCollection($[entity]){
$collection = Mage::getResourceModel('[module]/[entity]_category_collection')
->add[Entity]Filter($[entity]);
return $collection;
}
}
e un modello di risorsa app/code/local/[Namespace]/[Module]/Model/Resource/[Entity]/Category.php
:
<?php
class [Namespace]_[Module]_Model_Resource_[Entity]_Category
extends Mage_Core_Model_Resource_Db_Abstract {
protected function _construct(){
$this->_init('[module]/[entity]_category', 'rel_id');
}
public function save[Entity]Relation($[entity], $data){
if (!is_array($data)) {
$data = array();
}
$deleteCondition = $this->_getWriteAdapter()->quoteInto('[entity]_id=?', $[entity]->getId());
$this->_getWriteAdapter()->delete($this->getMainTable(), $deleteCondition);
foreach ($data as $categoryId) {
if (!empty($categoryId)){
$this->_getWriteAdapter()->insert($this->getMainTable(), array(
'[entity]_id' => $[entity]->getId(),
'category_id' => $categoryId,
'position' => 1
));
}
}
return $this;
}
}
e un modello di risorsa di raccolta: app/code/local/[Namespace]/[Module]/Model/Resource/[Entity]/Category/Collection.php
<?php
class [Namespace]_[Module]_Model_Resource_[Entity]_Category_Collection
extends Mage_Catalog_Model_Resource_Category_Collection{
protected $_joinedFields = false;
public function joinFields(){
if (!$this->_joinedFields){
$this->getSelect()->join(
array('related' => $this->getTable('[module]/[entity]_category')),
'related.category_id = main_table.entity_id',
array('position')
);
$this->_joinedFields = true;
}
return $this;
}
public function add[Entity]Filter($[entity]){
if ($[entity] instanceof [Namespace]_[Module]_Model_[Entity]){
$[entity] = $[entity]->getId();
}
if (!$this->_joinedFields){
$this->joinFields();
}
$this->getSelect()->where('related.[entity]_id = ?', $[entity]);
return $this;
}
}
Ora nell'azione save del tuo controller di amministrazione aggiungi questo prima di chiamare $[entity]->save()
$categories = $this->getRequest()->getPost('category_ids', -1);
if ($categories != -1) {
$categories = explode(',', $categories);
$categories = array_unique($categories);
$[entity]->setCategoriesData($categories);
}
Nel tuo modello di entità aggiungi questo in cima alla tua classe: protected $_categoryInstance = null;
e questi metodi ovunque:
protected function _afterSave() {
$this->getCategoryInstance()->save[Entity]Relation($this);
return parent::_afterSave();
}
public function getCategoryInstance(){
if (!$this->_categoryInstance) {
$this->_categoryInstance = Mage::getSingleton('[module]/[entity]_category');
}
return $this->_categoryInstance;
}
public function getSelectedCategories(){
if (!$this->hasSelectedCategories()) {
$categories = array();
foreach ($this->getSelectedCategoriesCollection() as $category) {
$categories[] = $category;
}
$this->setSelectedCategories($categories);
}
return $this->getData('selected_categories');
}
public function getSelectedCategoriesCollection(){
$collection = $this->getCategoryInstance()->getCategoryCollection($this);
return $collection;
}
Questo è tutto. Spero di non aver perso nulla. Il codice potrebbe richiedere alcune modifiche perché non so esattamente come sia costruito il tuo modulo, ma le idee principali ci sono. Con un po 'di debug dovresti farlo funzionare.
Nota: il codice sopra è stato generato utilizzando Ultimate Module Creator v1.9 .
Almeno per Magento 1.9 devi essere sicuro che extJs sia caricato.
Utilizzare uno dei seguenti metodi per attivare l'uso di extJS nel back-end:
Nel tuo controller usa questo:
$this->getLayout()->getBlock('head')->setCanLoadExtJs(true);
Nel tuo layout xml usa questo:
<reference name="head">
<action method="setCanLoadExtJs">
<value>1</value>
</action>
</reference>
