[TYPO3-mvc] Putting together a object for updateAction, from ExtJs/json

[dennis ahrens]

Hi Søren,

I've solved the problem like shown in the following action:

	/**
	 * Updates a record
	 *
	 * TODO: make the extjs Store to use the extbase controller parameter
signature, that we
	 * can fetch the data out of $this->request->getArgument('data');
	 *
	 * @return void
	 */
	public function updateAction() {
		try {
				// read and prepare data from POST
			$dataJson = t3lib_div::_POST('data');
			$dataArray = json_decode($dataJson,true);
			$uid = (int) t3lib_div::_POST('uid');
				// fetch the projekt that should be updated
			$forschungsprojekt = $this->forschungsprojektRepository->findByUid($uid);
				// apply the changes to the object
			$forschungsprojekt = $this->applyUpdate($dataArray,$forschungsprojekt);
				// apply the changes to the database
			$this->forschungsprojektRepository->update($forschungsprojekt);
				// sync group configuration for access management
			$this->accessManager->write($forschungsprojekt);
				// tell the view layer that everything is ok
			$this->view->assign('changedData',$dataArray);
			$this->view->assign('success',TRUE);
			$this->view->assign('message', '');
		} catch (Exception $e) {
			if (!is_array($dataArray))
				$dataArray = array();
				// tell the view layer that something is not ok ... :)
			$this->view->assign('changedData',$dataArray);
			$this->view->assign('success',FALSE);
			$this->view->assign('message','Forschungsprojekt konnte nicht
gespeichert werden');
				// tell the developer a little bit about the occured error
			t3lib_div::sysLog('Exception: ' .
$e->getMessage(),'FhhForschungsprojekte',4);
			t3lib_div::sysLog('Exception-Trace: ' .
$e->getTraceAsString(),'FhhForschungsprojekte',3);
		}
	}

The "mapping" between the json data and the model is hidden behind
applyUpdate().
I use the extjs jsonwriter config option 'writeAllFields' for just
telling the server about the made changes.

I think it would be much better to do the mapping when intializing the
action argument - but haven't found the time yet to dig deeper
there...

regards
Dennis
