[TYPO3-mvc] Mapping various Objects to a Domain Model

[Frank Krüger]

Good morning,

just a raw approach:

- decode your JSON-Data into a php object (json_decode)
- decide which model to use
- map the decoded JSON-Data onto your Model
(dataMapper->map('Tx_MyExt_Domain_Model_ServerXXX',
$myJsonDecodedDataArray);

You can create an instance of the dataMapper within your controller or your
repository using DI by

/**
 * @var Tx_Extbase_Persistence_Mapper_DataMapper
 */
protected $dataMapper;


/**
 * Injects the DataMapper to map nodes to objects
 *
 * @param Tx_Extbase_Persistence_Mapper_DataMapper $dataMapper
 * @return void
 */
public function injectDataMapper(Tx_Extbase_Persistence_Mapper_DataMapper
$dataMapper) {
	$this->dataMapper = $dataMapper;
}

Cheers,
Frank

Betreff: Re: [TYPO3-mvc] Mapping various Objects to a Domain Model

Hello Henjo,

I got several models of type "Server" and those share common properties like
"status" or "os" etc.

class Tx_MyExt_Domain_Model_Server_NewServer
extends Tx_MyExt_Domain_Model_Server;

class Tx_MyExt_Domain_Model_Server_SimpleServer
extends Tx_MyExt_Domain_Model_Server;

class Tx_MyExt_Domain_Model_Server_AwesomeServer
extends Tx_MyExt_Domain_Model_Server;

Now the raw data, which holds the original metadata for each server, is JSON
and every JSON object looks different among the various servers.

NewServer:
{status: 1, os: "Linux"}

SimpleServer:
{running: "yes", operatingSystem: "Windows"}

AwesomeServer:
{offline: FALSE}
// No OS set, but we know "AwesomeServer" runs "Ubuntu".

The Server Model looks like this:

class Tx_MyExt_Domain_Model_Server {

   /**
    * @var boolean
    */
   protected $status;

   /**
    * @var integer
    */
   protected $operatingSystem;

   // ...
}

Now I get this raw JSON objects from a web service and I want to have some
kind of helper object or helper functions which map/convert/populate those
JSON objects to my domain models.

I want to encapsulate this conversion/mapping inside a class/several
classes/methods/files.

Actually this is my question. What is the best solution to convert/map those
JSON data to my models in a flexible, extendable, easy to maintain way?

Thanks a lot,
Thomas
