62. 모임 만들기 폼 서브밋

모임 추가를 처리하는 핸들러 생성

package me.weekbelt.studyolle.event;

@Controller
@RequestMapping("/study/{path}")
@RequiredArgsConstructor
public class EventController {

    // ...........
    
    private final EventService eventService;
    private final ModelMapper modelMapper;

    // ...........

    @PostMapping("/new-event")
    public String newEventSubmit(@CurrentAccount Account account, @PathVariable String path,
                                 @Valid EventForm eventForm, Errors errors, Model model) {
        Study study = studyService.getStudyToUpdateStatus(account, path);
        if (errors.hasErrors()) {
            model.addAttribute("account", account);
            model.addAttribute("study", study);
            return "event/form";
        }

        Event event = eventService.createEvent(modelMapper.map(eventForm, Event.class), study, account);
        return "redirect:/study/" + study.getEncodedPath() + "/events/" + event.getId();
    }

}

 

모임 추가를 처리하는 createEvent메소드 작성

package me.weekbelt.studyolle.event;

@Service
@Transactional
@RequiredArgsConstructor
public class EventService {

    private final EventRepository eventRepository;

    public Event createEvent(Event event, Study study, Account account) {
        event.setCreatedBy(account);
        event.setCreatedDateTime(LocalDateTime.now());
        event.setStudy(study);
        return eventRepository.save(event);
    }
}

 

EventRepository 작성

package me.weekbelt.studyolle.event;

@Transactional(readOnly = true)
public interface EventRepository extends JpaRepository<Event, Long> {

}

 

모임 폼에 입력한 값중에 날짜 관련 처리를 검증하는 EventValidator 작성

package me.weekbelt.studyolle.event.validator;

@Component
public class EventValidator implements Validator {

    @Override
    public boolean supports(Class<?> aClass) {
        return EventForm.class.isAssignableFrom(aClass);
    }

    @Override
    public void validate(Object target, Errors errors) {
        EventForm eventForm = (EventForm) target;

        if (isNotValidEndEnrollmentDateTime(eventForm)) {
            errors.rejectValue("endEnrollmentDateTime", "wrong.datetime", "모임 접수 종료 일시를 정확히 입력하세요.");
        }

        if (isNotValidEndDateTime(eventForm)) {
            errors.rejectValue("endDateTime", "wrong.datetime", "모임 접수 종료 일시를 정확히 입력하세요.");
        }

        if (isNotValidStartDateTime(eventForm)) {
            errors.rejectValue("startDateTime", "wrong.datetime", "모임 시작 일시를 정확히 입력하세요.");

        }
    }

    private boolean isNotValidStartDateTime(EventForm eventForm) {
        return eventForm.getStartDateTime().isBefore(eventForm.getEndEnrollmentDateTime());
    }

    private boolean isNotValidEndEnrollmentDateTime(EventForm eventForm) {
        return eventForm.getEndEnrollmentDateTime().isBefore(LocalDateTime.now());
    }

    private boolean isNotValidEndDateTime(EventForm eventForm) {
        LocalDateTime endDateTime = eventForm.getEndDateTime();
        return endDateTime.isBefore(eventForm.getStartDateTime()) || endDateTime.isBefore(eventForm.getEndEnrollmentDateTime());
    }
}

 

EventController에 EventValidator등록

package me.weekbelt.studyolle.event;

@Controller
@RequestMapping("/study/{path}")
@RequiredArgsConstructor
public class EventController {

    // .....
    
    private final EventValidator eventValidator;

    @InitBinder("eventForm")
    public void initBinder(WebDataBinder webDataBinder){
        webDataBinder.addValidators(eventValidator);
    }

    // .....

}
