Custom import entity

Edit on GitHub
Log an Issue

This tutorial shows you how to extend the Magento/ImportExport/Model/Import/Entity/AbstractEntity class to import data into your custom module’s table. The current import entities can be found in System > Import:

  • Advanced Pricing
  • Products
  • Customers and Addresses (single file)
  • Customers Main File
  • Customer Addresses

To begin, suppose we have a custom table with the following structure:

entity_id name duration
     

Step 1: Adding a new entity type

Declare the new import entity:

etc/import.xml

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_ImportExport:etc/import.xsd">
    <entity name="learning" label="Learning Courses Import" model="OrangeCompany\Learning\Model\Import\Courses"
            behaviorModel="Magento\ImportExport\Model\Source\Import\Behavior\Basic" />
</config>

Extending the Magento_ImportExport module, we create a dependency to it in the module.xml file.

etc/module.xml

...
<sequence>
    <module name="Magento_ImportExport" />
</sequence>
...

Step 2: Defining the import model

As we extend the Magento/ImportExport/Model/Import/Entity/AbstractEntity, we implement the following abstract methods:

  • _importData - Import data rows
  • getEntityTypeCode - EAV entity type code getter
  • validateRow - Validating the row

Data validation

Sometimes, there is a need to validate data before inserting it into table. To do that, we have to add all our validation rules to validateRow method.

7
8
9
10
11
12
13

/**
 * Row validation
 *
 * @param array $rowData
 * @param int $rowNum
 *
 * @return bool
 */
public function validateRow(array $rowData, $rowNum): bool
{
    $name = $rowData['name'] ?? '';
    $duration = (int) $rowData['duration'] ?? 0;

    if (!$name) {
        $this->addRowError('NameIsRequired', $rowNum);
    }

    if (!$duration) {
        $this->addRowError('DurationIsRequired', $rowNum);
    }

    if (isset($this->_validatedRows[$rowNum])) {
        return !$this->getErrorAggregator()->isRowInvalid($rowNum);
    }

    $this->_validatedRows[$rowNum] = true;

    return !$this->getErrorAggregator()->isRowInvalid($rowNum);
}

We need to instantiate our new validation rules:

1
2
3
4
5
6
7
8
9
10
11
12
13
14

/**
 * Init Error Messages
 */
private function initMessageTemplates()
{
    $this->addMessageTemplate(
        'NameIsRequired',
        __('The name cannot be empty.')
    );
    $this->addMessageTemplate(
        'DurationIsRequired',
        __('Duration should be greater than 0.')
    );
}

And finally, call the initMessageTemplates method within __construct method:

1
2
3
4
5
6
7

public function __construct(
    ...
) {
    ...

    $this->initMessageTemplates();
}

The validation rules will be checking for a required name and a greater than 0 duration.

Validating Data

Step 3. Providing the sample file

To add the ability to download a sample csv file for our new entity, create the following file:

OrangeCompany/Learning/Files/Sample/learning.csv

With the following content:

1
2
3

entity_id,name,duration
,"First Course",90
,"Second Course",120

When updating the table’s data, you must provide the entity_id value for each row.

Next, register the sample file for our entity.

etc/di.xml

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <type name="Magento\ImportExport\Model\Import\SampleFileProvider">
        <arguments>
            <argument name="samples" xsi:type="array">
                <item name="learning" xsi:type="string">OrangeCompany_Learning</item>
            </argument>
        </arguments>
    </type>
</config>

Result

As result, the new Entity Type and the sample CSV are available:
