Magento model

某个字段保存不了 entity/customer _getDefaultAttributes添加字段名

$customer = Mage::getModel('customer/customer')->load(1);	
$customer->setData('is_charge', '2');
$customer->save(); //is_charge保存不成功原因

对某个字段进行算法操作或函数操作用new Zend_Db_Expr

array('point'=>new Zend_Db_Expr('pd.value*2'))

model/customer/customer.php

Mage::getSingleton('customer/customer')->setWebsiteId(Mage::app()->getStore()->getWebsiteId())->loadByEmail('[email protected]');

Model的启用,可以用Model下的文件 etc/config.xml

<models>
	<ticket>
		<class>Test_Ticket_Model</class>
		<resourceModel>ticket_mysql4</resourceModel>
	</ticket>
</models>

CURD操作：

public function createNewPostAction() { 
	$blogpost = Mage::getModel('ticket/log'); 
	$blogpost->setTitle('Code Post!'); 
	$blogpost->setPost('This post was created from code!'); 
	$blogpost->save(); 
	echo 'post created'; 
}

public function editFirstPostAction() { 
	$blogpost = Mage::getModel('ticket/log'); 
	$blogpost->load(1); //load($id, $field=null)   $filed = '键值'
	$blogpost->setTitle("The First post!"); 
	$blogpost->save(); 
	echo 'post edited'; 
}

public function deleteFirstPostAction() { 
	$blogpost = Mage::getModel('ticket/log'); 
	$blogpost->load(1); 
	$blogpost->delete(); 
	echo 'post removed'; 
}
//查询(select)语句
$connection = Mage::getSingleton('core/resource')->getConnection('core_read');
$select = "select * from table;"
//$select = $connection->select()->from('table', array('*')) ;
$rowsArray = $connection->fetchOne($select); // return row index0
$rowArray =$connection->fetchRow($select);   //return row

//插入(insert)语句
$fields = array();
$fields['name']= 'test';
$connection->insert('tablename', $fields);

//更新(update)语句
$connection->beginTransaction();
$fields = array();
$fields['name'] = 'jony';
$where = $connection->quoteInto('id =?', '1');
$connection->update('tablename', $fields, $where);
$connection->commit();

//删除(delete)语句
$condition = array($connection->quoteInto('id=?', '1'));
$connection->delete('tablename', $condition);

注意上面的getConnection()方法中的参数 "core_read"，表明了Magento将要使用的资源。与之相对应，当我们修改数据库的时候使用参数"core_write".一般情况下 getConnection方法的参数应设成"core_read" 或 "core_write"(应该不指定也是可以的，但是如果Magento有多个数据库就必须指定了 )。对应上面新增的module的名字.使用下面相对应的语句在read或write Database:

$conn = Mage::getSingleton('core/resource')->getConnection('ticket_read');
$conn = Mage::getSingleton('core/resource')->getConnection('ticket_write');

local\Test\Ticket\etc\config.xml  model添加资源模型和实体对象，可以用Model\Mysql4下的文件

<global>
	<models>
