DataTables a ukladani stavu na serveru

no jak to tak ctu po sobe tak je to asi trosku zmatene :)

je to to co si poslal.

tak ja neco splacam a pak to sem kdyz tak hodim. ale v prvotni fazi me hlavne zajima, kam je vhodne si stav komponent ukladat? do mysql? nebo sqlite nekam do tempu? nebo ma na to nette neco jineho? do sessen se mi to nelibi, protoze to neni zas tak trvale jak bych chtel

tak jsem dal neco dohromady. funguje to tak jen jestli to je z pohledu nette tak jak by asi melo?

neon

<?php
	services:
		database: @nette.database.default
		dataTableState: DataTableState\DataTableState(@database::table(datatable_state))
?>

sluzba pro ukladani a nacitani

<?php
class DataTableState {

	/** var Nette\Database\Connection $connection */
	private $connection;

	function __construct(\Nette\Database\Table\Selection $connection)
    {
        $this->connection = $connection;
    }

	public function saveState($name, $id, $data) {
		$this->connection->where(array("table" => $name, "user_id" => $id))->delete();
		$this->connection->insert(array('table' => $name, 'user_id' => $id, 'data' => $data));

	}

	public function loadState($name, $id) {
		$tmp = $this->connection->where(array("table" => $name, "user_id" => $id))->select('data')->fetch()->data;
		return $tmp;
	}
}
?>

komponenta

<?php
class DataTable  extends Control {
	/** var DataTablesState\DataTablesState $state */
	private $state;
	private $user_id = null;

	function __construct(DataTableState\DataTableState $state)
    {
        $this->state = $state;
    }

	protected function createTemplate($class = NULL) {
		$template = parent::createTemplate();
		$template->setFile(dirname(__FILE__) . '/DataTable.latte');
		return $template;
	}

	public function setUid($uid) {
		$this->user_id = $uid;
	}

	public function render() {
		$this->template->name = $this->name;
		return $this->template->render();
	}

	public function handleSaveState() {
		$tmp = $this->presenter->request->getPost();
		$this->state->saveState($this->name, $this->user_id, $tmp['jsonData']);
		$this->presenter->sendResponse(new \Nette\Application\Responses\JsonResponse(array()));
	}

	public function handleLoadState() {
		$data = $this->state->loadState($this->name, $this->user_id);
		$this->presenter->sendResponse(new \Nette\Application\Responses\JsonResponse(array($data)));
	}
}
?>

kousek z presenteru a sablonu sem nedavam, je to jeden radek

<?php
	public function createComponentTabulka($name) {
		$t = new DataTable\DataTable($this->context->getService('dataTableState'));
		$t->setUid($this->user->id);
		return $t;
	}
?>

dik :)

ted nevim jestli uplne chapu. takhle si to myslel?

<?php
class nejakyPresenter extends BasePresenter
{
	/** var DataTablesState\DataTablesState $saver */
	private $saver;

	function __construct(Nette\DI\Container $context) {
		parent::__construct($context);

		$this->saver = $context->getService('dataTableState');
	}



public function createComponentTableCdr($name) {
		$t = new DataTable\DataTable($this->saver);
		$t->setUid($this->user->id);
		$t->filter(false);
?>

aha, no me prave matlo to ze tam stejne ten context ( klavir? :) ) dat musim protoze ho potrebuje baseprasenter. tak mi prislo zbytecne to tam davat jeste jednou ale je to takhle jasnejsi to jo.

jj namespace sejmenuje stejne jako trida ale to si jen tak hraju, to pak nejak prejmenuju. se s temahle novotama zatim spis tak seznamuju :)
