Question

我整天都陷入困境，网络搜索的答案中没有一个能解决我的问题，所以我决定在这里发帖。在后端，它显示标题，菜单和页脚，网格空白空间。

    </myslideradmin_slider_index>
</layout>

调用

controller，调用slider.php，调用Grid.php构造函数，但不调用_prepareCollection（）和_prepareColumns（）。我无法找到原因。我需要你的帮助

尝试而不是使用布局，在控制器中使用以下内容：

$my_block = $this->getLayout()->createBlock('my_slider/adminhtml_slider');
$this->_addContent($my_block);

但没有输出：（

并为以下每一项我得到输出： 1 -

$my_block = $this->getLayout()->createBlock('my_slider/adminhtml_slider');
$this->_addContent($this->getLayout()->createBlock('core/text')->setText(get_class($my_block)));

2 -

$this->_addContent($this->getLayout()->createBlock('core/text')->setText('<h1>Success</h1>'));

将添加所需的任何代码或声明，提前致谢。

更新

发现/var/www/magento/app/design/adminhtml/default/default/template/widget/grid.phtml没有执行，不知道为什么......

Answer 1

分析我的模块的源代码，我的做法与你的不同，在网格中创建列。
