Question

我使用LexikFormFilterBundle来过滤实体及其关系。我试图添加apply_filter闭包，这样我就可以在运行查询之前修改我有过滤器的字段的值。无论我做什么，封闭都不会被调用。你们可以帮帮我，或者告诉我可能发生的事情。谢谢。

TimesheetController.php

    class TimesheetController extends Controller
    {


        public function indexAction(Request $request)
        {

            $form = $this->createForm(new TimesheetFilterType(), null, [
                'action' => $this->generateUrl('Homecare_HomecareBundle_dashboard_timesheets'),
                'method' => 'GET',
            ]);


            $filterBuilder = $this->getDoctrine()->getManager()->getRepository(
                'HomecareHomecareBundle:Timesheet'
            )->createQueryBuilder('t');
             //->join('t.recipient', 'r');

            $form->handleRequest($request);

            if ($form->isValid()) {

                $this->get('lexik_form_filter.query_builder_updater')
                     ->addFilterConditions($form, $filterBuilder);

                $timesheets = $filterBuilder->getQuery()->getResult();


               // dump($filterBuilder->getDql());
            }


            $timesheets = $filterBuilder->getQuery()->getResult();

            return $this->render(

我发现了伙计们。实际上需要在关联表单类型上添加'apply_filter'。然后它会工作。

symfony apply_filter无法在lexik表单过滤器上运行
