Magento類方法忽略不工作

Question

我試圖重寫Magento的目錄搜索功能，以便搜索條件使用'AND'而不是'OR'進行搜索。

做到這一點的「正確」方式，即更新證明，是創建我自己的模塊。所以這就是我所做的。不幸的是，這是行不通的。更新的方法未被調用。

這裏的配置文件部分：

<global> 
     <models> 
      <catalogsearch> 
       <rewrite> 
        <fulltext>MyNameSpace_MyModule_Model_CatalogSearch_Fulltext</fulltext> 
       </rewrite> 
      </catalogsearch> 
     </models> 
</global> 

我想覆蓋的方法是Mage_CatalogSearch_Model_Fulltext，和我其實在做一個「擴展」 - 例如，

class MyNameSpace_MyModule_Model_CatalogSearch_Fulltext extends Mage_CatalogSearch_Model_Fulltext 
{ 
    public function prepareResult($object, $queryText, $query) 
    { 
     die("It works..."); 
    } 
} 

我如果你真的試圖重寫的類從來沒有用特定類的創建者方法調用，那麼在某處讀取「重寫」是沒有意義的。如果這是真的，這可能解釋爲什麼我的新類方法從來沒有使用過？

那麼在那種情況下，如何覆蓋這個方法呢？我在這裏做正確的事情嗎？

Answer 1

正如Ashley指出的那樣，您必須尊重您壓倒一切的方法的聲明。
成才這樣工作的：

class MyNameSpace_MyModule_Model_CatalogSearch_Fulltext extends Mage_CatalogSearch_Model_Fulltext 
{ 

    public function prepareResult($query = null, $object = null, $queryText = null) 
    { 
     die('It works...'); 
    } 
}

你config.xml的下方喜歡。

<global> 
     <models> 
      <catalogsearch> 
       <rewrite> 
        <catalogsearch_fulltext>MyNameSpace_MyModule_Model_CatalogSearch_Fulltext</catalogsearch_fulltext> 
       </rewrite> 
      </catalogsearch> 
     </models> 
</global> 

而你的模型類應如下所示。

class MyNameSpace_MyModule_Model_CatalogSearch_Fulltext extends Mage_CatalogSearch_Model_Fulltext 
    { 
    // you should put default declaration of the function here. 
// inside the function change the development as you want. 
     public function prepareResult($query = null) 
     { 
      die('It works...'); 
     } 
    }

我已經成功覆蓋相同的功能看代碼： etc->模塊：LevoSoft_CatalogSearch.xml

<?xml version="1.0"?> 
 
<config> 
 
    <modules> 
 
     <LevoSoft_CatalogSearch> 
 
      <active>true</active> 
 
      <codePool>local</codePool> 
 
     </LevoSoft_CatalogSearch> 
 
    </modules> 
 
</config>

config.xml中

<config> 
 
    <modules> 
 
     <LevoSoft_CatalogSearch> 
 
      <version>1.0.0</version> 
 
     </LevoSoft_CatalogSearch> 
 
    </modules> 
 
    <global> 
 
     <models> 
 
      <catalogsearch_resource> 
 
       <rewrite> 
 
        <fulltext>LevoSoft_CatalogSearch_Model_Resource_Fulltext</fulltext> 
 
       </rewrite> 
 
      </catalogsearch_resource> 
 
     </models> 
 
    </global> 
 

 
</config>

CatalogSearch-> Modal->資源Fullteext.php

class LevoSoft_CatalogSearch_Model_Resource_Fulltext extends Mage_CatalogSearch_Model_Resource_Fulltext 
 
{ 
 
    /**

      if ($likeCond != '' && $searchType == Mage_CatalogSearch_Model_Fulltext::SEARCH_TYPE_COMBINE) {

      $sql = $adapter->insertFromSelect($select,
