Magento 2 错误 - 未定义模型集合资源名称

Question

我正在阅读 Magento 2 教程，但在调用 create() 方法后无法从自定义模型的工厂获取集合。它抛出一个错误说 "Model collection resource name is not defined"。我已经清除 /var/generation 并重新编译了 di.

Company/Module/Model/Vendor.php

namespace Company\Module\Model;

class Vendor extends \Magento\Framework\Model\AbstractModel {
    protected function _constructor() {
        $this->_init('Company\Module\Model\Resource\Vendor');
    }
}

Company/Module/Model/Resource/Vendor.php

namespace Company\Module\Model\Resource;

class Vendor extends \Magento\Framework\Model\ResourceModel\Db\AbstractDb
{
    protected function _construct()
    {
        $this->_init(
            'company_vendor',
            'vendor_id'
        );
    }
}

Company/Module/Model/Resource/Vendor/Collection.php

namespace Company\Module\Model\Resource\Vendor;

class Collection extends \Magento\Framework\Model\ResourceModel\Db\Collection\AbstractCollection
{
    protected function _construct()
    {
        $this->_init(
            'Company\Module\Model\Vendor',
            'Company\Module\Model\Resource\Vendor'
        );
    }
}

Company/Module/Block/VendorList.php

namespace Company\Module\Block;

class VendorList extends \Magento\Framework\View\Element\Template {

    protected $vendorFactory;


    public function __construct(\Magento\Framework\View\Element\Template\Context $context,
                                \Company\Module\Model\VendorFactory $vendorFactory,
                                array $data = [])
    {
        parent::__construct($context, $data);
        $this->vendorFactory = $vendorFactory;
    }

    public function getVendors() {
        return  $this->vendorFactory->create()->getCollection()->getItems(); //fails on getCollection()
    }

这是我得到的错误：

1 个异常：异常 #0 (Magento\Framework\Exception\LocalizedException)：未定义模型集合资源名称。

您需要进行以下更改。

Company/Module/Model/Vendor.php

namespace Company\Module\Model;

class Vendor extends \Magento\Framework\Model\AbstractModel {
    protected function _constructor() {
        $this->_init('Company\Module\Model\ResourceModel\Vendor');
    }
}

Company/Module/Model/ResourceModel/Vendor.php

namespace Company\Module\Model\ResourceModel;

class Vendor extends \Magento\Framework\Model\ResourceModel\Db\AbstractDb
{
    protected function _construct()
    {
        $this->_init('company_vendor','vendor_id');
    }
}

Company/Module/Model/ResourceModel/Vendor/Collection.php

namespace Company\Module\Model\ResourceModel\Vendor;

class Collection extends \Magento\Framework\Model\ResourceModel\Db\Collection\AbstractCollection
{
    public function _construct()
    {
        $this->_init('Company\Module\Model\Vendor','Company\Module\Model\ResourceModel\Vendor'
        );
    }
}

Answer 2

问题是我用的是 _constructor() 而不是 _construct()

namespace Company\Module\Model;

class Vendor extends \Magento\Framework\Model\AbstractModel {

    protected function _construct() {
        $this->_init('Company\Module\Model\Resource\Vendor');
    }
}
