“Unknown columns” error when executing a mass action

Question

I built up a grid with mass action similiar to this examples:

AbstractMassAction.php

Mass Cancel

When executing the code (see below) I get the following error message:

SQLSTATE[42S22]: Column not found: 1054 Unknown column '' in 'where clause', query was: SELECT main_table.* FROM my_custom_table AS main_table WHERE (IN('47', '48', '49')) AND ( IN('49'))

It seems that the code cannot identify the table columns when using the filter. Does anyone know what is the reason for this?

My Mass Action:

use Magento\Framework\App\ResponseInterface;
use Magento\Framework\App\Filesystem\DirectoryList;
use Vendor\MyModule\Model\ResourceModel\MyModel\CollectionFactory;
use Magento\Ui\Component\MassAction\Filter;
use Magento\Framework\App\Config\ScopeConfigInterface;
use Magento\Sales\Model\OrderFactory;
use Magento\Framework\Model\ResourceModel\Db\Collection\AbstractCollection;

Answer 1

It creates an issue because you didn't define $_idFieldName in your ResourceModel Collection

Please add this line in Vendor\MyModule\Model\ResourceModel\MyModel\Collectionfile.

     /**
     * @var string
     */
    protected $_idFieldName = 'YOUR_PRIMARY_KEY';

Where $_idFieldName is your table primary key.

Answer 2

In my case, the problem appeared because I put parent class invocation before the methods defining. And even though I had

protected $_idFieldName = 'YOUR_PRIMARY_KEY';

that didn't work me.
