Magento - 覆盖核心“评论”模块以添加自定义“电子邮件”字段

时间：2012-01-19 14:57:45

标签： php zend-framework magento

我需要创建一个自定义模块，该模块会覆盖现有的“评论”模块以添加额外字段“电子邮件ID”

我相信我需要重写核心模型文件' app / code / core / Mage / Review / Model / Resource / Review.php '，' app / code / core / Mage / Review / Model / Resource / Review / Product / Collection.php '和阻止文件' app / code / core / Mage / Adminhtml / Block / Review / Edit / Form.php “

此外，我不知道应该包含哪些安装脚本以及使用哪个版本来升级现有的“review_detail”表格。

到目前为止，这是我所做的代码，它不起作用。现在我在review_detail表中手动添加了'email'字段，并在base / default / template / review / form.phtml中添加了电子邮件输入字段

CM
 Review
   Block
     Review
       Edit
        Form.php
   etc
     config.xml
   Helper
     Data.php
   Model
     Resource
       Review.php
       Review
          Product
             Collection.php

这是我的config.xml文件

<?xml version="1.0"?>
 <config>
  <modules>
    <CM_Review>
     <version>0.0.1</version>
    </CM_Review>

        </rewrite>
    </adminhtml>
</blocks>

     </helpers>  
      <models>
       <review>
         <rewrite>
           <resource_review>CM_Review_Model_Resource_Review</resource_review>
            <resource_review_product_collection>
                CM_Review_Model_Resource_Review_Product_Collection
              </resource_review_product_collection>
         </rewrite>
      </review>
     </models>
    </global>
   </config>

我已复制粘贴原始块和模型文件的内容，并添加了“电子邮件”字段。但仍然无法保存任何数据。但是，直接编辑原始文件可以解决问题，但不能通过我的自定义模块。

有什么明显的我错过了吗？任何帮助指针都可以。感谢。

我没有收到任何错误，但该字段既没有保存到数据库也没有通过安装脚本代码添加。因此，我在代码中评论了资源部分，并手动添加了字段。这是我的代码，

有一个Helper / Data.php 

<?php
 class CM_Reviewmail_Helper_Data extends Mage_Core_Helper_Abstract {}

这是Model / Resource / Mysql4 / Setup.php 

<?php
class CM_Reviewmail_Model_Resource_Mysl4_Setup extends Mage_Core_Model_Resource_Setup {}

任何人都可以指出我做错了什么吗？还有什么需要做的？

请任何帮助表示赞赏。我一直在撞墙，需要尽快解决这个问题。提前谢谢。

重写类的方法看起来大部分是正确的，但请记住，您正在重写adminhtml/review_edit_form以指向CM_Review_Block_Review_Edit_Form，因此在app/code/local/CM/Review/Block/Review/Edit/Form.php中您需要声明该类：

<?php
    class CM_Review_Block_Review_Edit_Form extends Mage_Adminhtml_Block_Review_Edit_Form
    {

然后只覆盖你需要的功能。

不知道你是否已经这样做了。同一过程适用于您重写的任何模型。你不应该真的需要重写这个集合，但这取决于你需要做什么。

关于安装内容：

app/code/local/CM/Review/etc/config.xml

中的

<config>
    ...
    <resources>
        <review_setup>
            <setup>
                <module>CM_Review</module>
                <class>Mage_Sales_Model_Mysql4_Setup</class>
            </setup>
            <connection>
                <use>core_setup</use>
            </connection>
        </review_setup>
    </resources>
    ...
</config>

在app/code/local/CM/Review/sql/review_setup/mysql4-install-0.0.1.php 

<?php
    $installer = $this;
    $installer->startSetup();
    $installer->run("ALTER TABLE review_detail ADD COLUMN email_id INT NULL");
    $installer->endSetup();

如果这不是第一次（它应该，除非你已经尝试了类似的东西），进入数据库，并从表“{{1}”中删除“review_setup”行}”。然后再试一次。添加列后，请务必记住在core_resource

中刷新magento缓存

不要忘记您还需要在System > Cache Management中创建名为CM_Review.xml的文件。它应该是这样的：

app/etc/modules

希望这有帮助。

我弄清楚我做错了什么。我没有在config.xml中正确声明我的资源文件。这就是我现在的做法。

<models>
<review_resource>
     <rewrite>
       <review>CM_Reviewmail_Model_Resource_Review</review>
       <collection>CM_Reviewmail_Model_Resource_Review_Collection</collection>
       <product_collection>CM_Reviewmail_Model_Resource_Review_Product_Collection</product_collection>
    </rewrite>
 </review_resource>
</models>

然后我创建了上面提到的文件，确保扩展原始类并覆盖需要更改的函数。最后，我能够使用注册/访客客户的电子邮件ID保存数据库中的字段。

但是，当我尝试使用以下查询获取这些电子邮件值时，

 Mage::getModel('review/review')->getCollection()
                ->addFieldToFilter('email', $emailId)
                ->addFieldToFilter('status_id' , '1')
                ->addFieldToSelect('email')->getData();
它会给我任何回报。当我在phpMyAdmin中执行它时，我得到了这个查询

 SELECT `main_table`.`email`, `detail`.`detail_id`, `detail`.`title`, `detail`.`detail`, `detail`.`nickname`, `detail`.`customer_id` FROM `review` AS `main_table` INNER JOIN `review_detail` AS `detail` ON main_table.review_id = detail.review_id WHERE (email = 'test@test.com') AND (status_id = '1')

错误地说明了列表中的“未知main_table.email字段”。

现在任何人都可以帮我指出问题，以便为什么保存数据但不让我抓取它？为什么它在保存数据时无法识别我的字段？我的查询错了吗？

PS：但是如果我在phpMyAdmin的上述查询中用'email'替换'main_table.email'并执行它，它会返回正确的值。那么有没有办法通过废除'main_table'部分在代码中编写查询？

答案 2 :(得分：0)

这是错误

<product_collection>CM_Reviewmail_Model_Resource_Review_Product_Collection</product_collection>

应该是

<review_product_collection>CM_Reviewmail_Model_Resource_Review_Product_Collection</review_product_collection>
