Как добавить идентификатор объекта в скрытый ввод формы с помощью Thymeleaf

/ 09 ноября 2018

Я перечисляю рестораны в таблицу HTML, используя th: each. Я хотел бы добавить кнопку в каждую строку, где я могу удалить фактические данные строки (поэтому я хочу отправить идентификатор ресторана в Spring, затем я хотел бы удалить этот ресторан из базы данных. И в каждой строке я также хотел бы создайте форму Add admin (потому что я не хочу создавать новую страницу HTML для этого только с 1 полем ввода). Так что в основном мой вопрос, как я могу это сделать?

Вот моя таблица HTML: 

<table class="table">
                    <thead>
                    <tr>
                        <th scope="col">Restaurant</th>
                        <th scope="col">Delivery time</th>
                        <th scope="col">Delivery Price</th>
                        <th scope="col">Minimum Order Price</th>
                        <th scope="col">Shopping Hours</th>
                    </tr>
                    </thead>
                    <tbody>
                        <tr th:each="rest: ${restaurants}">

                            <td th:text="${rest.name}"/>
                            <td th:text="${rest.avgdeliverytime}"/>
                            <td th:text="${rest.deliveryprice}"/>
                            <td th:text="${rest.minorderprice}"/>
                            <td th:text="${rest.hours.open} + ' - '+ ${rest.hours.close}"/>
                            <td>

                                <form th:action="@{'restaurants/delete'}" method="post">
                                    <button type="submit" class="btn btn-danger btn-block"/>
                                    Delete</button>
                                </form>

                            </td>
                            <td>
                                <form th:action="@{'restaurants/newadmin'}" th:object="${restadmin}" method="post">
                                <input type="hidden" name="restaurantId" th:value="${rest.id}" th:field="${restadmin.restid}">
                                <input type="email" class="form-control" id="adminEmail" th:field="${restadmin.email}">
                                <button type="submit" class="btn btn-secondary btn-block"/>
                                Add Admin</button>
                                </form>

                            </td>
                        </tr>
                    </tbody>
                </table>

Для этого я создал новый класс с именем RestaurantAdmin, чтобы отправить этот объект обратно в Controller 

public class RestaurantAdmin {

private String email;
private Long restid;

public RestaurantAdmin() {
}

public RestaurantAdmin(String email, Long restid) {
    this.email = email;
    this.restid = restid;
}

public String getEmail() {
    return email;
}

public void setEmail(String email) {
    this.email = email;
}

public Long getRestid() {
    return restid;
}

public void setRestid(Long restid) {
    this.restid = restid;
}

Методы моего контроллера: 

    @GetMapping("/restaurants")
public String getAllRestaurants(Model model) {
    model.addAttribute("restaurants", restaurantService.findAll());
    model.addAttribute("restadmin", new RestaurantAdmin());
    return "administration/restaurants";
}
  @PostMapping("/restaurants/newadmin")
public ModelAndView addNewAdminToRestaurant(@ModelAttribute(value="restadmin") RestaurantAdmin restaurantAdmin,
                                            final BindingResult result, ModelAndView modelAndView) {

    if(result.hasErrors()) {
        modelAndView.addObject("error", "Some error are occured!");
        modelAndView.setViewName("administration/restaurants");
        return modelAndView;
    }

    System.out.println(restaurantAdmin.getRestid());
    System.out.println(restaurantAdmin.getEmail());

    modelAndView.setViewName("administration/restaurants");
    return modelAndView;
}

С этими кодами я не получаю никаких исключений, но когда я добавляю адрес электронной почты в форму «Добавить администратор», а затем публикую его в Spring, идентификатор restaurantAdmin имеет значение null.

Если я добавлю следующую строку в форму удаления (что на самом деле не имеет смысла, потому что у меня даже нет объекта для публикации или чего-то еще.) 

<input type="hidden" name="restaurantId" th:field="${rest.id}">

Я получаю это исключение:

Нельзя добавить th:value и th:field вместе, потому что th:field переопределит его.Что вы можете сделать, это удалить тег th:field и вместо этого использовать имя и значение.Таким образом, вместо получения @ModelAttribute, вы будете получать два @RequestParam.Для этого вам необходимо добавить следующие изменения в ваш код.

Контроллер 

@PostMapping("/restaurants/newadmin")
public ModelAndView addNewAdminToRestaurant(ModelAndView modelAndView,
           @RequestParam("restaurantId") Long id,
           @RequestParam("email") String email) { ... }

HTML 

<form th:action="@{'restaurants/newadmin'}" method="post">
    <input type="hidden" name="restaurantId" th:value="${rest.id}">
    <input type="email" name="email" class="form-control" id="adminEmail">
    <button type="submit" class="btn btn-secondary btn-block"/>Add Admin</button>
</form>

Совет

При использовании th:object с несколькими формами вместо отправки только одного RestaurantAdmin объекта, вы должны попытаться создать новый для каждой итерации.Простой способ сделать это - добавить @MadelAttribute к вашему контроллеру, который будет возвращать новый объект каждый раз, когда вы вызываете его в th:object.Конечно, для вашего случая это ничего не изменит, так как реальное решение - получить два параметра вместо объекта, но это всего лишь небольшой совет. 

// In order to use th:object in multiple forms, we must be able to map a new entity to that form.
@ModelAttribute(value = "newRestAdmin")
public RestaurantAdmin newRestAdmin() {return new RestaurantAdmin();}

Тогда на ваших формах вы просто выбираетеновая сущность с заданным значением. 

<form th:action="@{'restaurants/newadmin'}" th:object="${newRestAdmin}" method="post">
