The correct answers are A and C.

The errors in the snippet are:

• Column roll_no does not have an index. It is needed since attribute_identity is set to true.
• Column student_name does not have an attribute length.

Theattribute_identityattribute specifies whether the primary key of the table should be auto-incremented. Ifattribute_identityis set totrue, then theroll_nocolumn must have an index. Thestudent_namecolumn does not have an attribute length, which is required for string columns.

The following code shows how to fix the errors:

Once the errors have been fixed, the table can be created successfully.

To display the "file upload" field and process the actual CSV import, the following two requirements must be met:

• The developer must create a new system configuration setting that specifies the path to the CSV file.
• The developer must create a new controller action that handles the file upload and import process.

Thesystem.xmlfile is used to define system configuration settings. The following XML snippet shows how to define a new system configuration setting for the CSV file path:

XML

/path/to/csv/file

TheController\Adminhtml\ShipmentFeescontroller class is used to handle the file upload and import process. The following code shows how to create a new controller action that handles the file upload and import process:

PHP

public function uploadAction()

{

$file = $this->getRequest()->getFile('shipment_fees_csv_file');

if ($file->isUploaded()) {

$importer = new ShipmentFeesImporter();

$importer->import($file);

}

return $this->redirect('adminhtml/system_config/edit/section/shipment_fees');

}

To allow theis_delayedEAV attribute to be used in the .phtml cart page, the developer needs to create a new file calledetc/catalog_attributes.xmi. This file will contain the definition of theis_delayedattribute.

The following code shows how to create theetc/catalog_attributes.xmifile:

XML

Is Delayed

This attribute indicates whether the product is delayed.

10

false

Once theetc/catalog_attributes.xmifile has been created, theis_delayedattribute will be available in the .phtml cart page. The attribute can be accessed using thegetIsDelayed()method of theProductclass.

PHP

$product = $block->getProduct();

$isDelayed = $product->getIsDelayed();

TheisDelayedvariable will contain the value of theis_delayedattribute. If the value of the attribute is 1, then the product is delayed. If the value of the attribute is 0, then the product is not delayed.
