如何在magento中的自定义模块中创建表

问题描述 投票：0回答：4

我需要在 magento 中创建自定义扩展时创建一个新选项卡。 在这种情况下，不会创建任何表，并且会显示默认的 magento 错误页面。我在这里给出我的代码..请让我知道我哪里出了问题。 文件：/app/code/local/Somnath/Test/sql/test_setup/install-1.6.0.0.php

$installer = $this;

    /* @var $installer Mage_Core_Model_Resource_Setup */


    $installer->startSetup();


    $installer->run("

    -- DROP TABLE IF EXISTS {$this->getTable('somnath_test')};
    CREATE TABLE {$this->getTable('somnath_test')} (  
      `id` int(11) NOT NULL AUTO_INCREMENT,
      `fname` varchar(100) NOT NULL,
      PRIMARY KEY (`id`)
    ) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=4 ;

    ");

    $installer->endSetup();

我的config.xml文件是

<config>
  <modules>
    <Somnath_Test>
      <version>1.0.0</version>
    </Somnath_Test>
  </modules>

mysql4 的东西已经过时很长一段时间了。我建议使用以下内容：

config.xml 最少内容：

<?xml version="1.0"?>
<config>
    <modules>
        <Somnath_Blog>
            <version>1.0.0</version>
        </Somnath_Blog>
    </modules>
    <global>
        <models>
            <blog>
                <class>Somnath_Blog_Model</class>
                <resourceModel>somnath_blog_resource</resourceModel>
            </blog>
            <somnath_blog_resource>
                <class>Somnath_Blog_Model_Resource</class>
                <entities>
                    <blog>
                        <table>blog</table>
                    </blog>
                </entities>
            </somnath_blog_resource>
        </models>
        <resources>
            <somnath_blog_setup>
                <setup>
                    <module>Somnath_Blog</module>
                    <class>Mage_Core_Model_Resource_Setup</class> <!-- optional -->
                </setup>
            </somnath_blog_setup>
        </resources>
    </global>
</config>

您的sql安装脚本位于app/code/local/Somnath/Blog/sql/somnath_blog_setup/install-1.0.0.php

/** @var $installer Mage_Core_Model_Resource_Setup */
$installer = $this;

$installer->startSetup();

$table = $installer->getConnection()
    ->newTable($installer->getTable('blog/blog'))
    ->addColumn(
        'blog_id', Varien_Db_Ddl_Table::TYPE_INTEGER, null,
        array(
            'identity' => true,
            'unsigned' => true,
            'nullable' => false,
            'primary'  => true,
        ), 'Unique identifier'
    )
    ->addColumn(
        'title', Varien_Db_Ddl_Table::TYPE_TEXT, 100, array(), 'Blog title'
    )
    ->addColumn(
        'content', Varien_Db_Ddl_Table::TYPE_TEXT, null, array(), 'Blog content'
    )
    ->addColumn(
        'author', Varien_Db_Ddl_Table::TYPE_TEXT, 100, array(), 'Blog author'
    );

if (!$installer->getConnection()->isTableExists($table->getName())) {
    $installer->getConnection()->createTable($table);
}

$installer->endSetup();

当然，您还创建了基本模型/资源模型。

你的

config.xml
必须是这样的。

<?xml version="1.0"?>

    </global>
</config>

检查您是否扩展了资源收集。如果不是，那就必须是这样的。

<?php

class <Namespace>_<Module>_Model_Mysql4_<Module>_Collection extends Mage_Core_Model_Mysql4_Collection_Abstract
{
    public function _construct()
    {
        //parent::__construct();
        $this->_init('<module>/<module>');
    }
}

在etc文件夹中创建mysql4-install-0.1.0.php。并使用以下脚本在自定义模块中创建表。

<?php
$installer = $this;
$installer->startSetup();
$sql=<<<SQLTEXT
create table tablename(tablename_id int not null auto_increment, name varchar(100), primary key(tablename_id));
    insert into tablename values(1,'tablename1');
    insert into tablename values(2,'tablename2');

SQL文本；

$installer->run($sql);

$installer->endSetup();

?>

$installer = $this;

$installer->startSetup();

$installer->run("

CREATE TABLE `{$this->getTable('customer_form_table')}` (
`log_id` int(11) unsigned NOT NULL auto_increment,
`created_at` TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
`admin_id` int(11) unsigned NOT NULL default '0',
`customer_id` int(11) unsigned NOT NULL default '0',
`terms_old` int(11) unsigned NOT NULL default '0',

 PRIMARY KEY (`log_id`),
 INDEX (customer_id),
 INDEX (admin_id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

 ");

 $installer->endSetup();
