Question

我正在尝试覆盖Magento的目录搜索功能，以便使用“AND”而不是“OR”搜索搜索词。

执行此操作的“正确”方法，即更新证明，是创建我自己的模块。所以这就是我所做的。不幸的是，这不起作用。未调用更新的方法。

这是配置文件部分：

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

我试图覆盖的方法是Mage_CatalogSearch_Model_Fulltext，我实际上在做'扩展' - 例如，

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

我曾经读到某个地方，如果您实际上试图覆盖的类永远不会使用特定的类'creator'方法调用，那么这个'覆盖'是没有意义的吗？如果这是真的，这可以解释为什么我的新类方法从未使用过？

那么在这种情况下，如何覆盖此方法？我在这里做对了吗？

我已成功覆盖相同的功能，看看代码： etc-＆GT;模块：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>

您的config.xml应如下所示。

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

你的模型类应如下所示。

  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...');
        }
    }

Answer 3

正如阿什利指出的那样，你必须尊重你所覆盖的方法的声明有点像这样：

class MyNameSpace_MyModule_Model_CatalogSearch_Fulltext extends Mage_CatalogSearch_Model_Fulltext
{

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

Magento类方法覆盖不起作用
