Magento自定义模块网格不显示

sul*_*man 3 magento

所以我试图在我的自定义模块中显示一个网格(暂时显示任何内容,一旦它正在工作,我会担心它的集合!).

问题是我的网格小部件类的_prepareCollection()和/或_prepareColumns()方法似乎永远不会被调用,并且网格永远不会显示(按钮和标题文本也不会显示).(Magento管理页眉和页脚和导航显示正确.中间只是空白!)

这是我到目前为止:

应用程序/代码/本地/ myNameSpace对象/ Mymodule中的/ etc/config.xml中

<?xml version="1.0" ?>
<config>
    <modules>
        <MyNamespace_Mymodule>

    <!-- Define frontend and backend routers -->

然后我的控制器:

应用程序/代码/本地/ myNameSpace对象/ Mymodule中/控制器/ Adminhtml/MymoduleController.php

<?php
class MyNamespace_Mymodule_Adminhtml_MymoduleController extends Mage_Adminhtml_Controller_action
{
    public function indexAction() {
        $this->getLayout()->createBlock('mymodule/adminhtml_mymodule');
        $this->loadLayout();
        $this->renderLayout();
    }
}

然后在我的网格容器中:

应用程序/代码/本地/ myNameSpace对象/ Mymodule中/座/ Adminhtml/Mymodule.php

<?php
class MyNamespace_Mymodule_Block_Adminhtml_Mymodule extends Mage_Adminhtml_Block_Widget_Grid_Container
{
    public function __construct()
    {
        echo  __METHOD__ . " (Line #" . __LINE__ . ")<br/>";
        parent::__construct();
        $this->_controller = 'adminhtml_mymodule';
        $this->_blockGroup = 'mymodule';
        $this->_headerText = Mage::helper('mymodule')->__('my header text'); // this is not rendered
        $this->_addButtonLabel = Mage::helper('mymodule')->__('my button text'); // this is not rendered

    }

    protected function _prepareLayout()
    {
        $this->setChild( 'grid',
            $this->getLayout()->createBlock( $this->_blockGroup.'/' . $this->_controller . '_grid',

        return parent::_prepareLayout();

然后在我的网格小部件中:

应用程序/代码/本地/ myNameSpace对象/ Mymodule中/砌块/ Adminhtml/Mymodule中/ Grid.php

<?php
class MyNamespace_Mymodule_Block_Adminhtml_Mymodule_Grid extends Mage_Adminhtml_Block_Widget_Grid

    public function __construct()
    {
        parent::__construct();
        $this->setId('mymoduleGrid');
        $this->setDefaultSort('id');
        $this->setDefaultDir('ASC');
        $this->setSaveParametersInSession(true);
    }

    protected function _prepareCollection()
    {
        echo  __METHOD__ . " (Line #" . __LINE__ . ")<br/>"; // This is never called
        $collection = Mage::getModel('catalog/product')->getCollection(); // just a temp collection for the time being

        $this->setCollection($collection);
        return parent::_prepareCollection();

最后我的布局xml:

应用程序/设计/ adminhtml /默认/缺省/布局/ mymodule.xml

<?xml version="1.0"?>
<layout version="0.1.0">
    <adminhtml_mymodule_index>
        <reference name="content">
            <block type="mymodule/adminhtml_mymodule" name="mymodule" />
        </reference>
    </adminhtml_mymodule_index>
</layout>

日志中没有显示任何错误,我现在有点难过,其他SO答案似乎不合适.

有人说明为什么我的网格(即使是空的网格)没有显示?

谢谢.

编辑注意到某些类的错误情况(Mynamespace应该是MyNamespace).改变了它们但没有区别

这是布局的句柄标记的问题.

它应该是:

<?xml version="1.0"?>
<layout version="0.1.0">
    <mymodule_adminhtml_mymodule_index>
        <reference name="content">
            <block type="mymodule/adminhtml_mymodule" name="mymodule" />
        </reference>
    </mymodule_adminhtml_mymodule_index>
</layout>

有关解释和一些提示,您可以阅读:

我的布局未在我的Magento管理视图中加载

= UPDATE =

您也不需要$this->getLayout()->createBlock('mymodule/adminhtml_mymodule');按照您的控制方式调用控制器mymodule.xml

要么

您可以mymodule.xml通过将控制器的操作更改为:省略您的(无需调用它):

public function indexAction() {
    $this->loadLayout();
    $myblock = $this->getLayout()->createBlock('mymodule/adminhtml_mymodule');
    $this->_addContent($myblock);
    $this->renderLayout();
}

看到定义:

Mage_Adminhtml_Controller_Action

protected function _addContent(Mage_Core_Block_Abstract $block)
{
    $this->getLayout()->getBlock('content')->append($block);
    return $this;
}

以上这些代码做像一样的东西mymodule.xml,附加块'mymodule/adminhtml_mymodule'content

这都是你的选择!
