Question

我是magento的新人。我试图在我的控制器的动作中调用模型的方法，但不能这样做。我的文件夹结构是：

enter image description here

我的控制器是：

class Pw_Manageproducts_IndexController extends Mage_Core_Controller_Front_Action {
    public function indexAction() {
      $model = Mage::getModel('manageproducts/manageproducts');
       //trying to call modelCalls() which is in model class
       //$model->modelCalls();
        $this->loadLayout();
        $this->renderLayout();
    }
}

用于模型设置的config.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <global>
        <models>
            <manageproducts>
                <class>Manageproducts_Model</class>
                <resourceModel>Manageproducts_Mysql4</resourceModel>
                <manageproducts_mysql4>
                    <class>Pw_Manageproducts_Model_Mysql4</class>
                    <entities>
                        <manageproducts>
                            <table>blog_posts</table>
                        </manageproducts>
                    </entities>               
                </manageproducts_mysql4>
            </manageproducts>
         </models>   
    </global>
</config>

块就像：

class Pw_Manageproducts_Block_Manageproducts extends Mage_Core_Block_Template
{
    public function showAll(){
        echo "Srimanta";
    }
}

模型就像：

class Pw_Manageproducts_Model_Manageproducts extends Mage_Core_Model_Abstract {
    public function _construct() {
        $this->_init('manageproducts/manageproducts');
    }
    public function modelCalls(){
        return "This is a model function";
    }
}

我想在modelCalls()中调用IndexController函数。但它没有发生。我的最终目标是在design/frontend/default/default/template/pw/manageproducts/manageproducts.phtml的视图页面中显示消息（在模型中的modelCalls（）方法和块中的showAll（）方法）请让我知道我在哪里弄错了也请告诉我，不管我的程序是否正确。提前谢谢。

您的问题出在资源模型定义

中

<resourceModel>Manageproducts_Mysql4</resourceModel>

应该是

<resourceModel>manageproducts_mysql4<resourceModel>

Pw>Manageproducts>Model>Mysql4>Manageproducts.php的代码应该是

 <?php

    class Pw_Manageproducts_Model_Mysql4_Manageproducts extends Mage_Core_Model_Mysql4_Abstract
    {
        public function _construct()
        {   
            $this->_init('manageproducts/manageproducts', 'manageproducts_id');
        }
    }

我已经完成了模块中的更改，并根据您的要求进行了检查。它的工作原因请查看下面的代码。

下面是我的config.xml

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <Test_Helloworld>
            <version>0.1.0</version>
            <!-- Version of module -->
        </Test_Helloworld>
    </modules>

                    <module>Test_Helloworld</module>
                    <frontName>helloworld</frontName>
                    <!-- This is the URL
 of the module. i.e www.yourmagento.com/index.php/helloworld will be the url of your module. -->
                </args>
            </helloworld>
        </routers>
        <layout>

            </helloworld>
        </blocks>
        <models>

                <class>Test_Helloworld_Model</class>

        </models>
        <helpers>
            <helloworld>
                <class>Test_Helloworld_Helper</class>

                <connection>

                <connection>
                    <use>core_write</use>
                </connection>
            </helloworld_write>

        </resources>
    </global>
    <adminhtml>
        <acl>
            <resources>
                <admin>
                    <!--This is acl based on URL. If you see URL it would be /admin/system_config/ -->
                    <children>
                        <system>
                            <children>
                                <config>
                                    <children>
                                        <test translate="title" module="helloworld">
                                            <!-- This is name of the section created by us -->
                                            <title>Test Section ACL</title>
                                            <!-- Title as shown in User->Roles->Permissions Window -->
                                            <sort_order>99</sort_order>
                                        </test>
                                    </children>
                                </config>
                            </children>
                        </system>
                    </children>
                </admin>
            </resources>
        </acl>
    </adminhtml>
</config>

下面是我的模型文件，我已经声明了我的测试功能。

class Test_Helloworld_Model_Helloworld extends Mage_Core_Model_Abstract
{
    public function _construct()
    {
        parent::_construct();
        $this->_init('helloworld/helloworld'); // this is location of the resource file.
    }
    public function testMassge()
    {
       return "hi";
    }
}

在控制器中调用上面的函数：

<?php echo Mage::getModel('helloworld/helloworld')->testMassge(); ?>

所以请将它与你的模块结构进行比较。它会帮助你。

无法在magento中调用控制器中的模型函数
