php - 网格不显示在自定义 magento 模块中

Question

我正在尝试在 magento admin 中创建自定义模块。我已经达到了新链接已添加到菜单的程度，通过单击它，我可以导航到模块 Controller 的索引操作。但在这里我看不到网格，只出现标题文本和已添加到 block 构造中的按钮。

我的命名空间是:Mmnamespace
我的模块是:Mmmodule

我还使用以下命令创建了一个名为 mmmodule_event 的表

CREATE TABLE mmmodule_event (
    `event_id` INTEGER AUTO_INCREMENT PRIMARY KEY,
    `name` VARCHAR(255),
    `start` DATETIME,
    `end` DATETIME,
    `created_at` DATETIME,
    `modified_at` DATETIME
);

当前表中有两项是我使用 magento 的管理填充的

我可以看到，由于该 block 扩展了 Mage_Adminhtml_Block_Widget_Grid_Container 类，因此它本身会将此模块内的网格 block 添加为其子级。

我的配置设置 xml 文件如下:

P.S 我的编辑表单显示，但我的网格不显示，这里有什么我遗漏的

请按照以下链接创建前端和管理模块。 它将清晰地工作，不会在管理网格中产生任何问题。
