如何限制新产品块中显示的产品数量？通过cms/pages/design/Layout更新XML

<block type="catalog/product_new" name="home.catalog.product.new" template="catalog/product/new.phtml" >
   <action method="setColumnCount"><count>5</count></action> 
   <action method="setLimit"><limit>5</limit></action>
</block>

setLimit不起作用,也不起作用

<action method="setDefaultGridPerPage"><limit>5</limit></action>

要么:

<action method="setData"><key>limit</key><value>3</value></action>

要么:

<action method="setProductLimit"><count>5</count></action> 

要么:

<action method="setProductsLimit"><count>5</count></action> 

要么:

<action method="setProductsCount"><count>5</count></action>

我有一个集合:

$this->_totalVersions = Mage::getModel('downloads/files')
                                ->getCollection()
                                ->addFieldToFilter('customer_groups', array('like' => '%'.$customergroupId.'%'))
                                ->addFieldToFilter('main_table.is_active', 1)
                                ->getSize()

完美的工作!但是当我添加group它时它不起作用.

$this->_totalVersions = Mage::getModel('downloads/files')
                                ->getCollection()
                                ->addFieldToFilter('customer_groups', array('like' => '%'.$customergroupId.'%'))
                                ->addFieldToFilter('main_table.is_active', 1)
                                ->getSelect()->group(array('main_table.name'))
                                ->getSize()

我不想使用->count() 或count($collection) 因为它拥有90.000+项.

有没有正确的方法来计算收藏？
