Magento JoinLeft

Question

我正在嘗試將自定義表加入到客戶集合中。 自定義表：

+---------+--------------------+ 
| user_id | linked_customer_id | 
+---------+--------------------+ 
|  4 |     12 | 
+---------+--------------------+ 

我想將USER_ID添加到每個地方的customer_id匹配linked_customer_id項目。

我必須得下，但我收到：

柱未發現：1054未知列「main_table.entity_id」

$collection = Mage::getResourceModel('customer/customer_collection') 
     ->addNameToSelect() 
     ->addAttributeToSelect('entity_id') 
     ->addAttributeToSelect('email') 
     ->addAttributeToSelect('brand') 
     ->addAttributeToSelect('group_id') 
     ->joinAttribute('shipping_company', 'customer_address/company', 'default_shipping', null, 'left') 
     ->joinAttribute('billing_postcode', 'customer_address/postcode', 'default_billing', null, 'left') 
     ->joinAttribute('billing_city', 'customer_address/city', 'default_billing', null, 'left') 
     ->joinAttribute('shipping_telephone', 'customer_address/telephone', 'default_shipping', null, 'left') 
     ->joinAttribute('billing_region', 'customer_address/region', 'default_billing', null, 'left') 
     ->joinAttribute('shipping_country_id', 'customer_address/country_id', 'default_shipping', null, 'left') 
     ->joinAttribute('billing_vat_id', 'customer_address/vat_id', 'default_billing', null, 'left'); 

    $collection->getSelect()->joinLeft(
     array('salesrep' => 'custom_column'), 'main_table.entity_id=salesrep.user_id', 
     array('user_id' => 'salesrep.linked_customer_id') 
    ); 

    $this->setCollection($collection); 

Answer 1

我可能是錯的，但我認爲，因爲customer/customer是EAV模型，而不是一個平面模型，它使用表的別名是e而非main_table：

$collection->getSelect()->joinLeft(
    array('salesrep' => 'custom_column'), 
    'e.entity_id = salesrep.user_id', 
    array('user_id' => 'salesrep.linked_customer_id') 
); 

你會能夠通過調試select語句找到，例如：

echo (string) $collection->getSelect();
