Magento-錯誤的塊類型（自定義選項）

Question

我正在與教程戰斗： http ： //magento.ikantam.com/qa/custom-input-types-custom-options

當我打開自定義選項選項卡（產品編輯頁面）時出現錯誤：無效的塊類型： Mage_ProductSize_Block_Adminhtml_Catalog_Product_Edit_Tab_Options_Type_Instagramimage'

我不知道問題出在哪里； /為什么會有Mage_NAME而不是Rea_ProductSize_NAME？ 我在模塊內部的完整配置（跳過事件）

有類Rea_ProductSize_Block_Adminhtml_Catalog_Product_Edit_Tab_Options_Type_Instagramimage並像教程中一樣擴展了Mage_Adminhtml_Block_Catalog_Product_Edit_Tab_Options_Type_Abstract 。

Answer 1

確定在magento論壇上找到類似的錯誤。 名稱有問題：

<render>ProductSize/adminhtml_catalog_product_edit_tab_options_type_instagramimage</render> 

所以我在塊部分添加了快捷方式：

    <rea_productsize>
        <class>Rea_ProductSize_Block</class>
    </rea_productsize>

現在

<render>rea_productsize/adminhtml_catalog_product_edit_tab_options_type_instagramimage</render> 

工作正常
