How to use the Webman framework to implement calendar and event reminder functions?

Introduction:
In modern society, time management has become more and more important. As developers, we can use the Webman framework to build a powerful calendar application to help people better manage their time. This article will introduce how to use the Webman framework to implement calendar and event reminder functions, and attach code examples.

1. Build the environment
First, we need to build the development environment of the Webman framework. Please refer to the official Webman documentation, install the Webman framework, and create a new Web project.

2. Database design
Calendar and event reminder functions require the use of a database to store data. Here, we take the MySQL database as an example to illustrate. Create a database named "calendar" and create two tables: calendar and event.

Table calendar is used to store each user's calendar information, including user ID, calendar name and other fields. The event table is used to store event information, including event ID, event name, start time, end time and other fields. Please design the table structure according to actual needs and create the corresponding Model in the Webman framework.

3. Implement calendar function

1. Create calendar
   Users can create multiple calendars, each calendar has a unique name. In the Webman framework, we can handle related functions by creating a CalendarController.

Code example:

@Route("/calendar")
public class CalendarController extends Controller {

    @Inject
    private CalendarService calendarService;

    @Post("/create")
    public void createCalendar(String name) {
        // 创建日历
        calendarService.createCalendar(name);
        renderText("日历创建成功！");
    }
}

2. View Calendar
   Users can view calendars created by themselves. In the Webman framework, we can use Query to query data in the database and use HTML templates to render the data.

Code example:

@Route("/calendar")
public class CalendarController extends Controller {

    @Inject
    private CalendarService calendarService;

    @Get("/list")
    public void listCalendars() {
        // 查询日历列表
        List calendars = calendarService.listCalendars();
        assign("calendars", calendars);
        render("calendar/list.html");
    }
}

HTML template example (list.html):

    



    
日历列表
    

        #foreach($calendar in $calendars)
            
$calendar.name
        #end
    

4. Implement event reminder function

1. Create events
   Users can create events in the calendar, including event name, start time, end time and other information.

Code example:

@Route("/event")
public class EventController extends Controller {

    @Inject
    private EventService eventService;

    @Post("/create")
    public void createEvent(String name, String startTime, String endTime) {
        // 创建事件
        eventService.createEvent(name, startTime, endTime);
        renderText("事件创建成功！");
    }
}

2. View events
   Users can view all events in a calendar.

Code example:

@Route("/event")
public class EventController extends Controller {

    @Inject
    private EventService eventService;

    @Get("/list")
    public void listEvents(Long calendarId) {
        // 查询事件列表
        List events = eventService.listEvents(calendarId);
        assign("events", events);
        render("event/list.html");
    }
}

HTML template example (list.html):

    



    
事件列表
    

        #foreach($event in $events)
            
$event.name
        #end
    

Conclusion:
Through the Webman framework, we can easily implement Calendar and event reminder functions. You only need to set up the environment, design the database, implement the corresponding Controller and Service, and use HTML templates to render data.
