How to change boolean value if checked with checkbox in thymeleaf?
Question
I'm building weekly availability when a new user is registering. I'm using checkboxes to see what part of the day the user is available. For example if user is available on Monday until evening then user checks morning and evening under Monday.
th:field="${schedule.morning}" gives me and error. th:name="${schedule.morning}" doesn't change the boolean value.
Schedule model
@NotNull
@NotEmpty(message = "Day of the availability is required.")
private String day;
@NonNull
@Column(nullable = false)
private boolean morning;
@NonNull
@Column(nullable = false)
private boolean afternoon;
@NonNull
@Column(nullable = false)
private boolean evening;
Controller
@GetMapping("/new-agent")
public String register(Model model) {
ScheduleHelper availability = new ScheduleHelper();
model.addAttribute("user", new User());
model.addAttribute("profile", new Profile());
model.addAttribute("schedules", availability);
model.addAttribute("languages", languages);
return "profile_reg";
}
@PostMapping("/new-agent")
public String registerNewUser(@Valid User user, BindingResult bindingResultUser,
@Valid Profile profile, BindingResult bindingResult,
ScheduleHelper schedules, BindingResult bindingResultSchedule,
Model model, RedirectAttributes redirectAttributes) {
if(bindingResult.hasErrors() || bindingResultUser.hasErrors() || bindingResultSchedule.hasErrors()) {
// Show validation errors.
logger.info("Errors registering a new user.");
model.addAttribute("validationErrors", bindingResult.getAllErrors());
model.addAttribute("validationErrorsUser", bindingResultUser.getAllErrors());
model.addAttribute("validationErrorsSchedule", bindingResultSchedule.getAllErrors());
model.addAttribute("user", user);
model.addAttribute("profile", profile);
model.addAttribute("schedules", schedules);
model.addAttribute("languages", languages);
return "profile_reg";
} else {
schedules.print();
// Register new user.
User newUser = userService.register(user);
profile.setUser(newUser);
Profile newProfile = profileService.register(profile);
for(int i = 0; i < 7; i++) {
Schedule newSchedule = schedules.getSchedule(i);
newSchedule.setProfile(newProfile);
scheduleService.register(newSchedule);
}
redirectAttributes
.addFlashAttribute("id", newUser.getId())
.addFlashAttribute("success", true);
return "redirect:/new-agent";
}
}
Helper Class to pass the list when submitting
@Getter
@Setter
public class ScheduleHelper {
private List<Schedule> schedules;
ScheduleHelper(){
schedules = new ArrayList<>();
String[] week = {"Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"};
for(int i = 0; i < 7; i++) {
schedules.add(new Schedule(week[i]));
}
}
void print(){
Schedule schedule = schedules.get(1);
System.out.println(schedule.isMorning() + " " + schedule.isAfternoon() + " " + schedule.isEvening() + " " + schedule.getTest());
}
void addDay(String day){
schedules.add(new Schedule(day));
}

According to the official thymeleaf documentation
http://www.thymeleaf.org/doc/tutorials/2.1/usingthymeleaf.html#fixed-value-boolean-attributes
`th:checked is considered as a fixed-value Boolean attribute. So try like bellow.
<input type="checkbox" class="custom-control-input" th:checked="${schedule.morning}" th:id="|morning-${schedule.day}|" />
