Magento将自定义块添加到销售订单视图

我正在尝试将自定义块添加到Magento admin中的订单视图中。我遵循了教程，但它似乎不起作用

app/etc/modules/webs\u MyModule.xml

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <Webspeaks_MyModule>
            <active>true</active>
            <codePool>local</codePool>
        </Webspeaks_MyModule>
    </modules>
</config>

真的
地方的

            }
            else {
                $order = new Varien_Object();
            }
            $this->order = $order;
        }
        return $this->order;
    }

默认情况下，只有2个选项可以通过纯xml添加它。在内容之前和之后

<adminhtml_sales_order_view>
       <reference name="content">
           <block type="core/template" name="test-1" template="test/template.phtml" after="sales_order_edit"/>
           <block type="core/template" name="test-2" template="test/template.phtml" before="sales_order_edit"/>
       </reference>
   </adminhtml_sales_order_view>    

but those templates will be shown in all tabs.

to insert into several parts, you have to add your template like:

   <adminhtml_sales_order_view>
       <reference name="order_tab_info">
           <block type="core/template" name="test-1" template="test/template.phtml" after="sales_order_edit"/>
           <block type="core/template" name="test-2" template="test/template.phtml" before="sales_order_edit"/>
       </reference>
   </adminhtml_sales_order_view>    
Watch out for the changed reference name. 

In the corresponding template `app\design\adminhtml\default\default\template\sales\order\view\tab\info.phtml` you can place your block everywhere you want

   <div id="order-messages">
       <?php echo $this->getChildHtml('order_messages') ?>
   </div>
   <?php echo $this->getChildHtml('order_info') ?>
   <?php echo $this->getChildHtml('test-1') ?>

您有没有找到解决上述问题的方法
