カスタムエンティティのタブを追加するフォームファイルで、これも追加します。
$this->addTab('categories', array(
'label' => Mage::helper('[module]')->__('Associated categories'),
'url' => $this->getUrl('*/*/categories', array('_current' => true)),
'class' => 'ajax'
));
カスタムエンティティの管理コントローラーで、カテゴリのリクエストを処理する次の2つのアクション:
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'))
);
}
同じコントローラーにこのメソッドが存在することを確認してください:
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];
}
モジュールの管理レイアウトファイルで、カテゴリアクションにこのハンドルを追加します。
<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>
それでは、データの保存に進みましょう。
このためには、モジュールのインストール/アップグレードスクリプトのいずれかで以下が必要になります。これにより、リンクされた値が保存されるテーブルが作成されます
$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);
テーブルを宣言します。これをタグconfig.xml
内に追加します<[module]_resource><entities>
<[entity]_category>
<table>[module]_[entity]_category</table>
</[entity]_category>
カテゴリにリンクするためのモデルが必要になります。
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;
}
}
およびリソースモデル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;
}
}
およびコレクションリソースモデル: 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;
}
}
次に、管理コントローラーのsaveActionで、呼び出す前にこの権利を追加します $[entity]->save()
$categories = $this->getRequest()->getPost('category_ids', -1);
if ($categories != -1) {
$categories = explode(',', $categories);
$categories = array_unique($categories);
$[entity]->setCategoriesData($categories);
}
エンティティモデルで、これをクラスの最上部に追加します: protected $_categoryInstance = null;
これらのメソッドはどこにでも:
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;
}
それについてです。何も見逃していないことを願っています。あなたのモジュールがどのくらい正確に構築されているのかわからないので、コードにはいくつかの変更が必要かもしれませんが、主なアイデアはそこにあります。いくつかのデバッグを行うと、動作するはずです。
