Question

我目前正在尝试使用自编写的中间件将magento集成到ERP系统中。我收到这条消息：

Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`magento`.`catalog_product_entity`, CONSTRAINT     `FK_CAT_PRD_ENTT_ATTR_SET_ID_EAV_ATTR_SET_ATTR_SET_ID` FOREIGN KEY (`attribute_set_id`) REFERENCES `eav_attribute_set` (`a)

我真的不知道问题出在哪里。 Product get和Product write的结果看起来很相似。我已经检查了网络上的帮助，但无法找到解决方案。我也不知道在哪里搜索，因为顶部的消息是我得到的唯一消息。

任何帮助都会被激活。

代码本身分为多个部分

但我会尝试尽可能多地展示

Answer 1

请检查您是否在代码中使用了正确的属性集ID。请分享您编写代码的代码以更新/保存产品。

Answer 2

错误正在告诉您问题的确切原因。您正在尝试使用不正确的属性集ID保存产品。这意味着在这种情况下您设置或未设置的属性集ID不在eav_attribute_set表中。我认为这是因为如果你创建一个新产品，你就不会设置它。如果您要更新现有的，则无需进行设置。

if($this->product===false || $this->product->getId()<1){
    $this->product = Mage::getModel('catalog/product');
    $this->product->setSku($this->handler['art_nr']);
    // Set Attribute Set. Should be numeric for simple, bundle, configurable, grouped etc
    $this->product->setAttributeSetId($this->handler['art_attribute_set_id']); 
    $this->newProduct = true;
}
