[Flow] Resource Publishing

[Andre Hohmann]

Hallo, 

I have a few questions regarding Ressource Mangement. 

1.) 

Like described in
http://docs.typo3.org/flow/TYPO3FlowDocumentation/TheDefinitiveGuide/PartIII/ResourceManagement.html
I want to import an existing file. Therefore I created a Model file
"Download.php": 

<?php
namespace ITOOPAtcDomainModel;

class Download {

 /**
 * @var string
 */
 protected $title;

 /**
 * @var TYPO3FlowResourceResource
 */
 protected $originalResource;

 /**
 * @param string $title
 * @return void
 */
 public function setTitle($title) {
 $this->title = $title;
 }

 /**
 * @return string
 */
 public function getTitle() {
 return $this->title;
 }

 /**
 * @param TYPO3FlowResourceResource $originalResource
 * @return void
 */
 public function setOriginalResource(TYPO3FlowResourceResource
$originalResource) {
 $this->originalResource = $originalResource;
 }

 /**
 * @return TYPO3FlowResourceResource
 */
 public function getOriginalResource() {
 return $this->originalResource;
 }
} 

If I execute on a shell "./flow doctrine:update" I get the error "The
mapping of field 'originalResource' is invalid: The option 'OneToOne' is
required." If I add "@ORMManyToOne", and execute "./flow
doctrine:update" again, I get the error "SQLSTATE[HY000]: General error:
1005 Can't create table
 'atc.#sql-586_1978' (errno: 150)". If I drop the property "protected
$originalResource;" completely, I can execute "./flow doctrine:update"
without an error. Does anybody know, why? 

2.) 

I created a "DownloadRepository.php", too and the following
"DownloadController.php": 

class DownloadController extends ActionController {

 /**
 * @FlowInject
 * @var itoopatcDomainRepositoryDownloadRepository
 */
 protected $downloadRepository;

 /**
 * @FlowInject
 * @var TYPO3FlowResourceResourceManager
 */
 protected $resourceManager;

 /**
 * @return void
 * index action
 */
 public function indexAction() {

 }

 /**
 * Imports an image
 *
 * 
 * @return void
 */
 public function downloadAction() {

 // path, where the original file is stored 
 $csvPath =
'/var/www/apps/flow/Packages/Application/ITOOP.Atc/Resources/Private/Export/test.csv';

 // import original file into TYPO3 Flow's persistent resources storage
and
 // return a new Resource object which refers to the newly imported file
 $newResource = $this->resourceManager->importResource($csvPath);

 // create new object "download" which refers to the newly imported file
 $newDownload = new itoopatcDomainModelDownload();

 // attach the ressource to the new object "download"
 $newDownload->setOriginalResource($newResource);

 // get datetime
 $currentdatetime = new DateTime();
 // format datetime to string
 $cdt = $currentdatetime->format('YmdHis');
 // set datetime as title for new download object
 $newDownload->setTitle($cdt);

 // add new object "download" to downloadRepository
 $this->downloadRepository->add($newDownload);

 $this->redirect('index');
 }
} 

If I execute the downloadAction, everything works, so a new object with
an originalressource as hash an datetime as title is stored in the
database. (I know, I should completely forget sql tables and only think
of objects, but if I search for errors, sometimes I think it's easier
for me to prove in sql, what is stored). 

But now I don't understand, how to get access to the object/file! My aim
is to to provide the file stored unter
"/var/www/apps/flow/Packages/Application/ITOOP.Atc/Resources/Private/Export/test.csv"
as download for the application users, when they execute a special
action. When I try to make the file/object available in fluid by... 

"<a src="{f:uri.resource(resource: download.resource)}">Download</a>" 

...that doesn't work. Does anybody know, how to get access to the
object/file in a actionContoller?
