Magento getModel('catalog / product') - > getCollection(),addAttributeToSelect('*')没有返回描述

我有以下代码从magento获取所有产品数据,但它没有返回描述字段。我只是得到了short_description。实际上,除了描述之外,它缺少了几个字段。无论如何这里是代码:

$collection = Mage::getModel('catalog/product')->getCollection()
            ->joinField(
                    'qty', 'cataloginventory/stock_item', 'qty', 'product_id=entity_id', '{{table}}.stock_id=1', 'left'
            )
            ->addAttributeToFilter('status', 1) // enabled
            ->addUrlRewrite()
            ->addPriceData()
            ->addStoreFilter($store_id)
            ->addAttributeToSelect('*');
    Mage::getSingleton('catalog/product_status')->addSaleableFilterToCollection($collection);
    Mage::getSingleton('cataloginventory/stock')->addInStockFilterToCollection($collection);
    $collection->setOrder('sku', 'desc');

当我var_dump它时,这会创建以下查询:

SELECT 1 AS `status`, `e`.`entity_id`, `e`.`type_id`, `e`.`attribute_set_id`, `at_qty`.`qty`, `price_index`.`price`, `price_index`.`tax_class_id`, `price_index`.`final_price`, IF(price_index.tier_price IS NOT NULL, LEAST(price_index.min_price, price_index.tier_price), price_index.min_price) AS `minimal_price`, `price_index`.`min_price`, `price_index`.`max_price`, `price_index`.`tier_price`, `e`.`entity_id`, `e`.`attribute_set_id`, `e`.`type_id`, `e`.`allow_open_amount`, `e`.`cost`, `e`.`created_at`, `e`.`email_template`, `e`.`enable_googlecheckout`, `e`.`giftcard_amounts`, `e`.`giftcard_type`, `e`.`gift_message_available`, `e`.`gift_wrapping_available`, `e`.`gift_wrapping_price`, `e`.`has_options`, `e`.`image_label`, `e`.`is_recurring`, `e`.`is_redeemable`, `e`.`lifetime`, `e`.`links_exist`, `e`.`links_purchased_separately`, `e`.`links_title`, `e`.`msrp`, `e`.`msrp_display_actual_price_type`, `e`.`msrp_enabled`, `e`.`name`, `e`.`news_from_date`, `e`.`news_to_date`, `e`.`open_amount_max`, `e`.`open_amount_min`, `e`.`price`, `e`.`price_type`, `e`.`price_view`, `e`.`recurring_profile`, `e`.`required_options`, `e`.`shipment_type`, `e`.`short_description`, `e`.`sku`, `e`.`sku_type`, `e`.`small_image`, `e`.`small_image_label`, `e`.`special_from_date`, `e`.`special_price`, `e`.`special_to_date`, `e`.`tax_class_id`, `e`.`thumbnail`, `e`.`thumbnail_label`, `e`.`updated_at`, `e`.`url_key`, `e`.`url_path`, `e`.`use_config_email_template`, `e`.`use_config_is_redeemable`, `e`.`use_config_lifetime`, `e`.`visibility`, `e`.`weight`, `e`.`weight_type`, `e`.`brand`, `e`.`brand_value`, `e`.`new_in`, `e`.`new_in_value`, `e`.`amconf_simple_price`, `e`.`volume_weight`, `e`.`product_3rd_type`, `e`.`product_3rd_type_value`, `e`.`product_sub_type`, `e`.`product_sub_type_value`, `e`.`product_type`, `e`.`product_type_value`, `e`.`parent_sku`, `at_inventory_in_stock`.`is_in_stock` AS `inventory_in_stock` FROM `catalog_product_flat_1` AS `e`
 LEFT JOIN `cataloginventory_stock_item` AS `at_qty` ON (at_qty.`product_id`=e.entity_id) AND (at_qty.stock_id=1)
 INNER JOIN `catalog_product_index_price` AS `price_index` ON price_index.entity_id = e.entity_id AND price_index.website_id = '1' AND price_index.customer_group_id = 0
 INNER JOIN `cataloginventory_stock_item` AS `at_inventory_in_stock` ON (at_inventory_in_stock.`product_id`=e.entity_id) AND ((at_inventory_in_stock.use_config_manage_stock = 0 AND at_inventory_in_stock.manage_stock=1 AND at_inventory_in_stock.is_in_stock=1) OR (at_inventory_in_stock.use_config_manage_stock = 0 AND at_inventory_in_stock.manage_stock=0) OR (at_inventory_in_stock.use_config_manage_stock = 1 AND at_inventory_in_stock.is_in_stock=1))

所以只有short_description,但我不知道为什么描述不存在。

我知道我能做到

Mage::getModel('catalog/product')->load($product->getId())

但我不想多次查询数据库。有没有办法解决这个问题,或者在我执行getCollection()时获取这些字段?

更新:似乎我的主要问题是,当我运行第一个代码时,我只获得必填字段。在我得到$collection的部分中,我想在产品的描述页面中包含其他字段。如果没有对每个产品进行加载,那么代码是什么?

当使用像这样的模型集合时,Magento最初不会加载所有属性,

$collections = Mage::getModel('catalog/product')->getCollection(); 

选择表格

SELECT `e`.* FROM `catalog_product_entity` AS `e`

Magento使用orm表。如果我们在这里挖掘更多,

foreach($collections as $collection) {
    echo $collection->getName();
}

现在你可以看到额外的quires将会运行。

但是您可以从平面表中获取所有产品详细信息集,而无需多次查询数据库。为此,您需要在admin-> system->configuration ->catalog->catalog-> Front end->中启用单位 在这里,您可以看到启用平面目录的选项

Use Flat Catalog Category -> Enable
Use Flat Catalog Product  -> Enable

有关平面目录的详细信息,请转到 here

所以现在你会看到它想要的查询,

SELECT 1 AS statuseentity_idetype_ideattribute_set_ideentity_ideattribute_set_idetype_ideallow_open_amount,{{ 1}}。ecostecreated_ateemail_templatee,{{1} }。enable_googlecheckoutegiftcard_amountsegiftcard_typeegift_message_availableegift_wrapping_availableegift_wrapping_priceehas_optionseimage_labele。{{ 1}},is_recurringeis_redeemableelifetimeelinks_exist。{{1} },elinks_purchased_separatelyelinks_titleemsrpemsrp_display_actual_price_typeemsrp_enabledenameenews_from_dateenews_to_date,{{ 1}}。eopen_amount_maxeopen_amount_minepricee,{{1} }。price_typeeprice_viewerecurring_profileerequired_optionseshipment_typeeshort_descriptioneskuesku_typee。{{ 1}},small_imageesmall_image_labelespecial_from_dateespecial_price。{{1} },especial_to_dateetax_class_idethumbnailethumbnail_labeleupdated_ateurl_keyeurl_patheuse_config_email_template,{{ 1}}。euse_config_is_redeemableeuse_config_lifetimee FROM visibility AS e

但是请记住,平面目录中没有一些方法,如果它被禁用,也可以使用。

请尝试将description字段“Used in Product Listing”的产品属性设置为“YES”。这将解决您的问题并避免单个产品模型加载。

但请确保在更改此属性后,您必须重新索引数据。
