How to Attach a Download Sample File Link to the Import Functionality in Magento 2
To attach a "Download Sample File" to the Import functionality in Magento 2, you'll need to create a custom import entity and configure it properly within your module. This process involves several key steps, including creating a custom import.xml file to register your new entity, mapping the entity to a sample file in di.xml, and placing a sample CSV file in the appropriate directory within your module.
How to Attach a Download Sample File Link to the Import Functionality in Magento 2
Step 1: Define the Custom Import Entity
Create an import.xml file in your module's etc directory to register the new import entity.
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_ImportExport:etc/import.xsd">
<entity name="custom_entity" label="Custom Entity"
model="Vendor\Module\Model\Import\CustomEntity"
behaviorModel="Magento\ImportExport\Model\Source\Import\Behavior\Basic"/>
</config>
name: Unique identifier for the entity.label: Display name in the admin panel.model: Class handling the import logic.behaviorModel: Defines import behaviors like append or replace.
Step 2: Configure Dependency Injection
In your module's etc/di.xml, map the custom entity to its sample file provider.
<?xml version="1.0"?>
<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="custom_entity" xsi:type="string">Vendor_Module</item>
</argument>
</arguments>
</type>
</config>
This configuration tells Magento where to find the sample file for the custom entity.
Step 3: Implement the Import Model
Create the import model class specified in import.xml.
<?php
namespace Vendor\Module\Model\Import;
use Magento\ImportExport\Model\Import\Entity\AbstractEntity;
class CustomEntity extends AbstractEntity
{
public function getEntityTypeCode()
{
return 'custom_entity';
}
// Implement required abstract methods here
Ensure all necessary methods are implemented to handle the import process.
Step 4: Provide the Sample CSV File
Place the sample CSV file in the following path within your module:
Vendor/Module/view/adminhtml/files/sample/custom_entity.csv
This file should contain headers and sample data corresponding to the fields expected by your import model.
Step 5: Test the Import Functionality
- Navigate to System > Data Transfer > Import in the Magento admin panel.
- Select "Custom Entity" from the "Entity Type" dropdown.
- Click "Download Sample File" to retrieve the sample CSV.
- Verify the file downloads correctly and contains the expected data.
