Ako spravne pracovat s JSONom v komponente

Chcel by som do Nette projektu implementovat KendoUI Datagrid. Datagrid som naimplementoval ako komponent a ten vykreslujem v sablone.

ALE: Neviem, ako by som mal spravne riesit JSON, keby som mal vsetko „natlacene“ v presenteri, tak by mi to ani tak nevadilo, ale ked ma byt komponent znovupouziteny, mala by byt JSON komunikacia jeho sucastou a ja ju mam v presenteri, co asi nie je OK.

class LaboratoryPositionsGridControl extends Control
{

    public function render()
    {
		// Neviem, ako spravne poriesit ten JSON
        $transport = new Kendo\Data\DataSourceTransport();
        $read = new Kendo\Data\DataSourceTransportRead();
        $read->url('/msa/www/my_presenter?do=loaddata')
            ->contentType('application/json')
            ->type('POST');
        $transport->read($read)
            ->parameterMap('function(data) {
              return kendo.stringify(data);
          }');

        $model = new Kendo\Data\DataSourceSchemaModel();

        $titleField = new Kendo\Data\DataSourceSchemaModelField('title');
        $titleField->type('string');

/*
.
.
.
*/
        $model->addField($titleField);

        $schema = new Kendo\Data\DataSourceSchema();
        $schema->data('data')
            ->errors('errors')
            ->groups('groups')
            ->model($model)
            ->total('total');

        $dataSource = new Kendo\Data\DataSource();

        $dataSource->transport($transport)
            ->pageSize(100)
            ->serverPaging(true)
            ->serverSorting(true)
            ->serverGrouping(true)
            ->schema($schema);

        $grid = new Kendo\UI\Grid('grid');

        $titleColumn = new Kendo\UI\GridColumn();
        $titleColumn->field('title')
            ->title('Sign')
            ->width(100);

        $grid->addColumn($titleColumn)
            ->dataSource($dataSource)
            ->sortable(true)
            ->filterable(true)
            ->pageable($pageable)
            ->attr('style', 'height:600px');


        echo $grid->render();
    }

…a v presenteri mam toto:

public function handleLoaddata()
{
    if ($this->isAjax()) {
        $request = json_decode($this->getHttpRequest()->getRawBody());

			// Datasource som upravil na Nette\Database
        $result = new \Helpers\KendoUI\DataSourceResult($this->context);

        $json = $result->read('view_lab_positions', array(
            'title'), $request);

        $this->payload->total = $json['total'];
        $this->payload->data = $json['data'];
        $this->sendPayload();
    }
}
