Question

Я использую планировщик DHTMLX в своем проекте с использованием фреймворка Symfony.все хорошо, я могу успешно создавать события и добавлять их в базу данных, а затем отображать их.но каждый раз, когда я пытаюсь отредактировать или удалить, отображается сообщение «Ошибка: невозможно удалить или невозможно редактировать».

schedulerScript.js
scheduler.html.twig
SchedulerController.php

:

// 1. Configure Scheduler Basic Settings
scheduler.config.xml_date="%Y-%m-%d %H:%i";
scheduler.config.first_hour = 6;
scheduler.config.last_hour = 24;
scheduler.config.limit_time_select = true;
scheduler.config.details_on_create = true;
// Disable event edition with single click
scheduler.config.select = false;
scheduler.config.details_on_dblclick = true;
scheduler.config.max_month_events = 5;
scheduler.config.resize_month_events = true;

// 2. Configure Lightbox (form) sections
scheduler.config.lightbox.sections = [
    // If you have another field on your Appointment entity (e.g example_field column), you would add it like
    // {name:"Example Field", height:30, map_to:"example_field", type:"textarea"},
    {name:"Title", height:30, map_to:"text", type:"textarea"},
    {name:"Description", height:70, map_to:"description", type:"textarea"},
    {name:"time", height:72, type:"time", map_to:"auto"}
];

// 3. Start calendar with custom settings
var initSettings = {
    // Element where the scheduler will be started
    elementId: "scheduler_element",
    // Date object where the scheduler should be started
    startDate: new Date(),
    // Start mode
    mode: "month"
};

scheduler.init(initSettings.elementId, initSettings.startDate , initSettings.mode);

// 4. Parse the initial (From index controller) appointments
scheduler.parse(window.GLOBAL_APPOINTMENTS, "json");

// Retrieve the format date method (that follows the given pattern) from the scheduler library
var formatDate = scheduler.date.date_to_str("%d-%m-%Y %H:%i:%s");
