(Magento 1.7) How to modify the report module? - sql

Question

I followed a tutorial to create report module and the tutorial show me exactly what I wanted. Now, I would like to modify the database into my database. There are two tables that I want to join (member_download and sales_payment). What should I modify from this code to link it into my database?
Here is the code:
<?php
class Wcl_ReportNewOrders_Model_Reportneworders extends Mage_Reports_Model_Mysql4_Product_Ordered_Collection
{
function __construct() {
parent::__construct();
}
protected function _joinFields($from = '', $to = '')
{
$this->addAttributeToSelect('name')
->addAttributeToSelect('increment_id')
->addOrderedQty($from, $to)
->setOrder('sku', self::SORT_ORDER_ASC);
//Mage::log('SQL: '.$this->getSelect()->__toString());
return $this;
}
public function addOrderedQty($from = '', $to = '')
{
$adapter = $this->getConnection();
$compositeTypeIds = Mage::getSingleton('catalog/product_type')->getCompositeTypes();
$orderTableAliasName = $adapter->quoteIdentifier('order');
$addressTableAliasName = 'a';
$downloadTableAliasName = 'download';
$orderJoinCondition = array(
$orderTableAliasName . '.entity_id = order_items.order_id',
$adapter->quoteInto("{$orderTableAliasName}.state = ?", Mage_Sales_Model_Order::STATE_PROCESSING),
);
$addressJoinCondition = array(
$addressTableAliasName . '.entity_id = order.shipping_address_id'
);
$downloadJoinCondition = array(
$downloadTableAliasName . '.order_id = order_items.order_id'
);
$productJoinCondition = array(
//$adapter->quoteInto('(e.type_id NOT IN (?))', $compositeTypeIds),
'e.entity_id = order_items.product_id',
$adapter->quoteInto('e.entity_type_id = ?', $this->getProductEntityTypeId())
);
if ($from != '' && $to != '') {
$fieldName = $orderTableAliasName . '.created_at';
$orderJoinCondition[] = $this->_prepareBetweenSql($fieldName, $from, $to);
}
$this->getSelect()->reset()
->from(
array('order_items' => $this->getTable('sales/order_item')),
array(
'qty_ordered' => 'order_items.qty_ordered',
'order_items_name' => 'order_items.name',
'order_increment_id' => 'order.increment_id',
'sku' => 'order_items.sku',
'type_id' => 'order_items.product_type',
'shipping_address_id' => 'order.shipping_address_id'
))
->joinInner(
array('order' => $this->getTable('sales/order')),
implode(' AND ', $orderJoinCondition),
array())
->joinLeft(
array('a' => $this->getTable('sales/order_address')),
implode(' AND ', $addressJoinCondition),
array(
'shipto_name' => "CONCAT(COALESCE(a.firstname, ''), ' ', COALESCE(a.lastname, ''))"
),
array())
->joinLeft(
array('e' => $this->getProductEntityTableName()),
implode(' AND ', $productJoinCondition),
array(
'created_at' => 'e.created_at',
'updated_at' => 'e.updated_at'
))
->where('parent_item_id IS NULL')
//->group('order_items.product_id')
->having('order_items.qty_ordered > ?', 0);
return $this;
}
public function addItem(Varien_Object $item)
{
$itemId = $this->_getItemId($item);
if (!is_null($itemId)) {
if (isset($this->_items[$itemId])) {
// Unnecessary exception - http://www.magentocommerce.com/boards/viewthread/10634/P0/
//throw new Exception('Item ('.get_class($item).') with the same id "'.$item->getId().'" already exist');
}
$this->_items[$itemId] = $item;
} else {
$this->_items[] = $item;
}
return $this;
}
}
Please tell me how to modify the database. I am new with magento. Thanks!

Answer 1

i checked your link that you provided. open file at below location
Wcl_ReportNewOrders_Block_Adminhtml_ReportNewOrders_Grid
below is the function where you can modify the database
protected function _prepareCollection() {
parent::_prepareCollection();
// Get the data collection from the model
$this->getCollection()->initReport('reportneworders/reportneworders');
return $this;
}
Replace the above code with below code
protected function _prepareCollection() {
parent::_prepareCollection();
$collection = $this->getCollection()->initReport('reportneworders/reportneworders');
/*
perform your desired operation here
// print_r((string)$collection->getSelect();
*/
$this->setCollection($collection);
return $this;
}
