Magento:数量更新时自动更改库存_库存_可用性 [英] Magento: Auto-change inventory_stock_availability on quantity update

问题描述

在我们的Magento商店中，我们正在使用扩展名条形码运输"来更新库存(

In our Magento Shop we're updating our Stock with the extension "Barcode Shipping"(http://www.magentocommerce.com/magento-connect/barcode-shipping.html) or the custom Productgrid from the extension "Enhanced Admin Grids (+ Editor)" (http://www.magentocommerce.com/magento-connect/enhanced-admin-grids-editor.html).

如果销售产品并且库存量达到0，则属性stock_stock_availability设置为缺货".如果库存已更新，我们总是必须手动将属性stock_stock_availability设置为有库存".

If a product is sold and the stock quantity reaches 0, the attribute inventory_stock_availability is set to "Out of Stock". If the stock is updated, we always have to set the attribute inventory_stock_availability manually to "In Stock".

当库存水平更新为大于0的值时，是否可以将库存量自动设置为库存中"?也许是自定义扩展程序正在监听触发的事件?

Is there a way to automatically set the stock availability to "In Stock" when the stock level updates to a value greater than 0? Maybe a custom extension listening to a triggered event?

推荐答案

我通过结合使用@DWils答案和cronjob找到了一种合适的方法.

I found a suitable approach by using a combination of @DWils answer and cronjob.

在我的扩展程序配置(应用程序/代码/本地/我/UpdateStockAvailability/etc/config.xml)中:

In my extension config (app/code/local/My/UpdateStockAvailability/etc/config.xml):

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <My_UpdateStockAvailability>
            <version>1.0.0</version>
        </My_UpdateStockAvailability>
    </modules>
    <global>
         <models>
            <my_updatestockavailability>
                <class>My_UpdateStockAvailability_Model</class>
            </my_updatestockavailability>
        </models>
        <events>
            <catalog_product_save_after>
                <observers>
                    <my_updatestockavailability>
                        <class>my_updatestockavailability/observer</class>
                        <method>updateStockAvailability</method>
                        <type>singleton</type>
                    </my_updatestockavailability>
                </observers>
            </catalog_product_save_after>
        </events>
    </global>

    <crontab>
        <jobs>
            <updatestockavailabilitycronjob>
                <schedule>
                    <cron_expr>*/15 7-19 * * *</cron_expr>
                </schedule>
                <run>
                    <model>my_updatestockavailability/observer::updateCronAction</model>
                </run>
            </updatestockavailabilitycronjob>
        </jobs>
    </crontab>
</config>

我的观察者(app/code/local/My/UpdateStockAvailability/Model/Observer.php):

My observer (app/code/local/My/UpdateStockAvailability/Model/Observer.php):

<?php

class My_UpdateStockAvailability_Model_observer {

    public function updateStockAvailability(Varien_Event_Observer $observer) {
        $product = $observer->getProduct();
        $stockData = $product->getStockData();

        if ( $product && $stockData['qty'] ) {
            $stock = Mage::getModel('cataloginventory/stock_item')->loadByProduct($product->getEntityId()); // Load the stock for this product
            $stock->setData('is_in_stock', 1); // Set the Product to InStock
            $stock->save(); // Save
        }
    }

    public function updateCronAction() {
        $collection = Mage::getResourceModel('cataloginventory/stock_item_collection');
        $outQty = Mage::getStoreConfig('cataloginventory/item/options_min_qty');
        $collection->addFieldToFilter('qty', array('gt' => $outQty));
        $collection->addFieldToFilter('is_in_stock', 0);

        foreach ($collection as $item) {
            $item->setData('is_in_stock', 1);
        }
        $collection->save();

        $bundleCollection = Mage::getModel('catalog/product')->getCollection()
            ->addAttributeToSelect('*')
            ->addAttributeToSelect('type')
            ->addAttributeToFilter('type_id', 'bundle')
            ->joinField('is_in_stock', 'cataloginventory/stock_item', 'is_in_stock', 'product_id=entity_id', '{{table}}.stock_id=1', 'left')
            ->addAttributeToFilter('is_in_stock', array('eq' => 0));

        foreach ($bundleCollection as $bundle) {
            $selectionCollection = $bundle->getTypeInstance(true)->getSelectionsCollection($bundle->getTypeInstance(true)->getOptionsIds($bundle), $bundle);

            $allInStock = true;
            foreach ($selectionCollection as $option) {
                $stockItem = $option->getStockItem();
                if ($stockItem->getQty() <= 0 || $stockItem->getIsInStock() <= $outQty) {
                    $allInStock = false;
                }
            }

            if ($allInStock) {
                $stockItem = Mage::getModel('cataloginventory/stock_item')->loadByProduct($bundle);
                $stockItem->setData('is_in_stock', 1);
                $stockItem->save();
            }
        }
    }
}

最后，模块xml(app/etc/modules/My_UpdateStockAvailability.xml):

Finally the module xml (app/etc/modules/My_UpdateStockAvailability.xml):

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <My_UpdateStockAvailability>
            <active>true</active>
            <codePool>local</codePool>
        </My_UpdateStockAvailability>
    </modules>
</config>
