AD0-E716 Adobe Commerce Developer with Cloud Add-on Questions and Answers

The possible reason why the payment method is missing in the admin is that in the module config.xml, the node can_use_internal was not set to true. This node determines whether the payment method can be used in the admin area or not. If it is set to false or omitted, the payment method will not be available for admin orders. To enable the payment method for admin use only, the node can_use_internal should be set to true and the node can_use_checkout should be set to false.

The developer can deal with this issue by modifying the admin path timeout value in seconds in the Fastly Configuration section > Advanced Configuration in the Admin Panel. Fastly is a cloud-based caching service that improves site performance and security for Adobe Commerce Cloud projects. Fastly has a default timeout value of 180 seconds for admin requests, which means that any request that takes longer than 180 seconds will be terminated and result in a timeout error. The developer can increase this value to allow longer processing time for admin requests without causing errors. The developer also needs to save the configuration and upload VCL to Fastly to apply the changes. Verified References: [Magento 2.4 DevDocs]

According to the Magento Stack Exchange answer, form key validation is a security feature that prevents CSRF attacks by checking if the form key in the request matches the one generated by Magento. If the developer does not include the form_key in their custom form, the validation will fail and an error will be shown. Therefore, the developer needs to add the form_key to their requests by using getBlockHtml (‘formkey’) ?> in their template file.

Two features that come out of the box with Adobe Commerce Cloud are Support ACL and Fastly. Support ACL is a feature that allows the developer to manage access control lists for different users and roles on the Adobe Commerce Cloud platform. The developer can create and assign permissions for different actions and resources on the project and environment levels. Fastly is a cloud-based caching service that improves site performance and security forAdobe Commerce Cloud projects. Fastly provides features such as CDN, image optimization, WAF, DDoS protection, etc. Verified References: [Magento 2.4 DevDocs] 3

The developer can add a virtual type for Myvendor\MyModuie\Modei\customPdfupioader specifying the aiiowedExtensions and the maxFiiesize for the constructor, within the module’s di.xmi. This way, the developer can reuse the existing file uploader class and customize it for the specific field without modifying the core code.

The developer can test the new feature under the integration environment by deactivating one of the active integration environment branches, creating a new active branch from integration and installing the module, and pushing the changes. This is because Enhanced Integration Environments have a limit of four active branches at a time, and each branch has its own dedicated database and services. The developer can use the Cloud CLI for Commerce tool to manage the branches and deploy the code changes.

The developer can add a custom filter to the virtual type Magento\Catalog\Model\Api\SearchCriteria\CollectionProcessor\ProductFilterProce5sor for supplier_id field. In the custom filter, the developer can apply the needed join and filter to the passed $collection. This is the recommended way to extend the search criteria for products using dependency injection and plugins. Verified References: [Magento 2.4 DevDocs] [Magento Stack Exchange]

The type of environment that will be provisioned when launching the CLI for Commerce command magento-cloud environment:branch is an integration environment with the code and database from the parent environment. Integration environments are temporary environments that are used for testing and development purposes on the Adobe Commerce Cloud platform. They can be created from any branch of code and have their own dedicated database and services. When creating an integration environment using the CLI for Commerce command, the code and database from the parent environment are copied to the new integration environment, creating an exact replica of the parent environment.

According to the Develop data and schema patches guide for Magento 2 developers, data patches can also implement PatchRevertabieinterface to provide rollback functionality for their changes. The revert() method contains the instructions to undo the data modifications made by the patch. To ensure that the product attribute is removed when the module is uninstalled, the developer should make the data patch implement PatchRevertabieinterface and implement the revert method to remove the product attribute using EavSetupFactory or AttributeRepositoryInterface.

According to the Magento Stack Exchange answer, system.xml is a file that defines the configuration fields for the admin area. Each field can have a validate attribute that specifies avalidation rule for the field value. Magento provides some built-in validation rules, such as phoneUS, which validates a US telephone number. Therefore, to ensure that the option contains a valid US telephone number, the developer needs to add phoneUS to the field in system.xml.

The developer needs to add environment level environment variables to be sure that the payment configurations are always properly set on the Staging environment. Environment variables are configuration settings that affect the behavior of the Adobe Commerce Cloud application and services. Environment variables can be set at the project level or the environment level. Project level variables apply to all environments, while environment level variables override the project level variables for a specific environment. The developer can useenvironment level variables to customize the payment configurations for the Staging environment without affecting other environments. Verified References: [Magento 2.4 DevDocs]

The developer has to add a formkey for the new export option because the formkey is required for security reasons. Without the formkey, the request will be rejected and redirected to the dashboard page. Verified References: [Magento 2.4 User Guide] [Magento 2.4 DevDocs]

To configure the tracking_level parameter indi.xmlto have a value of 4 for theDownloadclass and all classes that extendDownload, the developer would use the following code:

Thesettingelement is used to set a configuration value for a specific model. Therewriteelement is used to override the default configuration value for a specific model. In this case, thetracking_levelparameter is set to 4 for all models that extendDownload.

Two ways to access the PHP error logs on Adobe Commerce Cloud are to use the dedicated command from Cloud CLI for Commerce and to connect to the servers via SSH and localize the log files. The Cloud CLI for Commerce is a command-line tool that allows developers to interact with their Adobe Commerce Cloud projects and environments. The developer can use the command magento-cloud log php to view or download the PHP error logs from any environment. Alternatively, the developer can connect to the servers via SSH and navigate to the var/log directory where the PHP error logs are stored.

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.

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');

}

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:

XML

int

true

true

false

int

false

true

false

true

true

string

255

false

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