自定义模块网格容器将不会显示

Question

我知道这个问题在SO上被问过这么多次但是没有什么能帮助我解决我的问题。

我正在尝试在我的模块索引页面上显示网格，但它没有显示，我在循环中尝试var_dump Mage::getModel('custombundle/bundle')->getCollection()并且它给了我输出数据。以下是我到目前为止编码的内容：

config.xml中

您的管理路线未正确定义。您不应该添加新的管理员路由，因为它会产生安全问题，而且非常不鼓励。

<admin>
    <routers>
        <adminhtml>
            <args>
                <modules>
                    <Company_CustomBundle after="Mage_Adminhtml">Company_CustomBundle_Adminhtml</Company_CustomBundle>
                </modules>
            </args>
        </adminhtml>
    </routers>
</admin>

Answer 2

Rajeev和Jaimin可以在Magento stackexchange上正确回答这个问题，您可以查看答案以及讨论here。这些人真的提供了宝贵的意见，并提出了改进代码质量的改进建议。

我将尝试解释一下我在代码中所做的更正，以解决我的问题。

<强> config.xml中

<admin>
    <routers>
        <adminhtml>
            <args>
                <modules>
                    <company_custombundle before="Mage_Adminhtml">Company_CustomBundle_Adminhtml</company_custombundle>
                </modules>
            </args>
        </adminhtml>
    </routers>
</admin>

在config.xml部分，我更改了router部分，因为<use>admin</use>从1.9版本开始被弃用，并且具有Mladen Ilić所述的潜在安全威胁。

然后相应地更正了config.xml的菜单部分以支持新的路由，如下所示：

<menu>
    <custombundle module="custombundle">
        <title>Custom Bundle</title>
        <sort_order>100</sort_order>
        <children>
            <index module="custombundle">
                <title>Custom Bundle</title>
                <sort_order>0</sort_order>
                <action>adminhtml/custombundle/index</action>
            </index>

            <other module="custombundle">
                <title>Other</title>
                <sort_order>0</sort_order>
                <action>adminhtml/custombundle/other</action>
            </other>
        </children>
    </custombundle>
</menu>

阻止/ Adminhtml / Custombundle / Bundle.php

class Company_CustomBundle_Block_Adminhtml_Custombundle_Bundle extends Mage_Adminhtml_Block_Widget_Grid_Container
{
    public function __construct()
    {
        $this->_controller = 'adminhtml_custombundle_bundle';
        $this->_blockGroup = 'company_custombundle';
        $this->_headerText = Mage::helper('custombundle')->__('Custom Bundle Category combinations');
        $this->_addButtonLabel = Mage::helper('custombundle')->__('Add Item');
        parent::__construct();
    }
}

现在我已将adminhtml_custombundle更改为adminhtml_custombundle_bundle此更改已完成，因为如果您查看Mage_Adminhtml_Block_Widget_Container::_prepareLayout()方法，您将会知道您的容器的孩子即{{1}如果您不这样做，我或永远不会调用grid。

上述代码中的另一项更改是Block/Adminhtml/Custombundle/Bundle/Grid.php我将其值从Mage::Helper()更改为company_custombundle，即没有命名空间。

毕竟我清除了magento的缓存并重新加载... * Bingo网格显示数据。
