无法检索实体配置 Magento

Question

我一直在跟踪唯一一个我不知道的错误，因为它显示了我多久。

下面是我的 config.xml 文件

我在哪里犯错了？我能理解。

Answer 1

您缺少资源设置文件。 这些行：

<resources>
    <questionanswer_setup>
        <setup>
            <module>Maven_Questionanswer</module>
        </setup>
        <connection>
            <use>core_setup</use>
        </connection>
    </questionanswer_setup>
        <questionanswer_write>
            <connection>
                <use>core_write</use>
            </connection>
        </questionanswer_write>
        <questionanswer_read>
            <connection>
                <use>core_read</use>
            </connection>
        </questionanswer_read>
 </resources>

应该是：

<resources>
    <questionanswer_setup>
        <setup>
            <module>Maven_Questionanswer</module>
            <class>Maven_Questionanswer_Model_Resource_Setup</class>
        </setup>
        <connection>
            <use>core_setup</use>
        </connection>
    </questionanswer_setup>
        <questionanswer_write>
            <connection>
                <use>core_write</use>
            </connection>
        </questionanswer_write>
        <questionanswer_read>
            <connection>
                <use>core_read</use>
            </connection>
        </questionanswer_read>
 </resources>

换行：

<class>Maven_Questionanswer_Model_Resource_Setup</class>

资源设置文件应该是这样的：

<?php

class Maven_Questionanswer_Model_Resource_Setup extends Mage_Core_Model_Resource_Setup {
}

希望对你有帮助

Answer 2

请尝试以下代码，

<?php

$installer = $this;
 $installer->startSetup();
 $table = $installer->getConnection()->newTable($installer->getTable('question'))
    ->addColumn('question_id', Varien_Db_Ddl_Table::TYPE_INTEGER, null, array(
        'unsigned' => true,
        'nullable' => false,
        'AUTO_INCREMENT'=>true,
        'primary' => true,
        'identity' => true,
        ), 'Question ID')
    ->addColumn('username', Varien_Db_Ddl_Table::TYPE_TEXT, null, array(
        'nullable' => false,
        ), 'Username')
    ->addColumn('email', Varien_Db_Ddl_Table::TYPE_TEXT, null, array(
        'nullable' => false,
        ), 'Email username')
    ->addColumn('question', Varien_Db_Ddl_Table::TYPE_TEXT, null, array(
        ), 'Question')
    ->addColumn('product_id', Varien_Db_Ddl_Table::TYPE_INTEGER, null, array(
        ), 'Product ID')
    ->addColumn('store_id', Varien_Db_Ddl_Table::TYPE_INTEGER, null, array(
        ), 'Store ID')
    ->addColumn('status', Varien_Db_Ddl_Table::TYPE_INTEGER, null, array(
        ), 'Status')
    ->setComment('questionanswer questionanswer/question entity table');
    $installer->getConnection()->createTable($table);

$installer->endSetup();
?>
