Контейнеры данных и Загрузчики данных

test327594 · 10.07.2019 06:00:37

Добрый день!

Реализую FileMultiUploadField но при загрузке файла он не появляется в таблице. Раньше это можно было решить вот так: filesDs.refresh(). Как реализовать с использованием загрузчиков и контейнеров?
Еще подскажите как делать правильно делать сложные запросы? При использовании datasource в дескрипторе можно было задавать запросы так: [CDATA[select e from daex$RPD e where e.expertiseRPD = :ds$expertiseDs]] и использовать один результат для другого запроса. В текущей документации нашел пример лишь при программном задании запросов.

Здравствуйте,

Перезагрузить данные вы можете воспользовавшись API DataLoader#load:

getScreenData().getLoader("loaderId").load();

Автоматическая подстановка параметров в запросы не была поддержана в новом API специально - теперь параметры нужно устанавливать явно.

Использую getScreenData().getLoader("loaderId").load(); но запись в таблице после загрузки не появляется.

multiUploadField.addQueueUploadCompleteListener(queueUploadCompleteEvent -> {
for (Map.Entry<UUID, String> entry : multiUploadField.getUploadsMap().entrySet())
 {
   UUID fileId = entry.getKey();
   String fileName = entry.getValue();
   FileDescriptor fd = fileUploadingAPI.getFileDescriptor(fileId, fileName);
   try {
        fileUploadingAPI.putFileIntoStorage(fileId, fd);
   } catch (FileStorageException e) {
   throw new RuntimeException("Error saving file to FileStorage", e);
   }
   dataManager.commit(fd);
   }
   notifications.create()
        .withCaption("Файлы загружены: " + multiUploadField.getUploadsMap().values())
        .show();
   multiUploadField.clearUploads();
   //TODO: Обновление формы и источников
   getScreenData().getLoader("remarkAnswerDl").load();
});

Если добавлять в таблицу методом Add то запись появляется.

<data>
        <instance id="remarkAnswerDc"
                  class="com.company.daex.entity.RemarkAnswer"
                  view="remarkAnswer.Edit">
            <loader id="remarkAnswerDl"/>
            <collection id="filesRemarkAnswerDc" property="filesRemarkAnswer"/>
        </instance>
    </data>

tsarev · 10.07.2019 06:41:54

А FileDescriptor после загрузки корректно сохраняется?

test327594 · 10.07.2019 06:43:07

Да. Его потом можно найти во внешних файлах и через Add.

test327594 · 16.07.2019 05:08:49

Заметил что не происходит сохранения в таблицу ссылок. Сам файл сохраняется корректно, но добавление записи файла в таблицу ссылок не происходит. При попытке сделать так:

getEditedEntity().getFilesRemarkAnswer().add(fd);

получаю NullPointer.
Можете подсказать что делаю не так?

sergeevms.33 · 16.07.2019 19:00:14

Попробуйте работать с filesRemarkAnswerDc напрямую.

test327594 · 17.07.2019 03:55:31

Если обращаться напрямую к filesRemarkAnswerDc то это Datasource или я ошибаюсь?

tsarev · 17.07.2019 05:52:42

Не могли бы вы прислать лог ошибки?

tsarev · 17.07.2019 05:53:53

filesRemarkAnswerDc

Это CollectionContainer связанный с редактируемой сущностью через свойство filesRemarkAnswer.

Пробую сделать на другой таблице:

Screen screen = screenBuilders.lookup(Customer.class,this)
                .withSelectHandler(es->{
                    for (Customer item : es)
                    {
                        ExpertiseCustomerPDBuilder myClass = new ExpertiseCustomerPDBuilder();
                        myClass.setCustomer(item);
                        myClass.setExperise(getEditedEntity());
                        dataManager.commit(myClass);
                    }
                })
                .build()
                .show();

        screen.addAfterCloseListener(e->{
            expertiseCustomerPDBuildersDl.load();//1
            getScreenData().getLoader("expertiseCustomerPDBuildersDl")//2
        });

Как способ 1 так и способ 2 не обновляют таблицу!
Но если добавить еще одну запись в таблицу, добавится первая. Если переключить вкладки загрузится. Возможно не перерисовывается таблица? Или дело во вкладках?

tsarev · 19.07.2019 05:18:04

Судя по коду и по ошибке, поле filesRemarkAnswer не ссылается ни на что (null), поэтому при попытке добавить элемент в коллекцию вы получаете NullPointerException.

Вам будет достаточно инжектировать collection контейнер в контроллер экрана и добавлять FileDescriptor'ы через него:

@Inject
protected FileMultiUploadField uploadField;
@Inject
protected CollectionPropertyContainer<FileDescriptor> filesDc;

@Subscribe("uploadField")
private void onUploadFieldQueueUploadComplete(FileMultiUploadField.QueueUploadCompleteEvent event) {
    if (getEditedEntity().getFiles() == null) {
        getEditedEntity().setFiles(new ArrayList<>());
    }

    for (Map.Entry<UUID, String> entry : uploadField.getUploadsMap().entrySet()) {
        // saving to storage is skipped

        filesDc.getMutableItems()
                .add(dataManager.commit(fd));
    }
}

test327594 · 19.07.2019 06:28:06

Сделал вот так:

@Subscribe("multiUploadField")
    private void onMultiUploadFieldQueueUploadComplete(FileMultiUploadField.QueueUploadCompleteEvent event)
    {
        for (Map.Entry<UUID, String> entry : multiUploadField.getUploadsMap().entrySet())
        {
            UUID fileId = entry.getKey();
            String fileName = entry.getValue();
            FileDescriptor fd = fileUploadingAPI.getFileDescriptor(fileId, fileName);
            try {
                fileUploadingAPI.putFileIntoStorage(fileId, fd);
            } catch (FileStorageException e) {
                throw new RuntimeException("Error saving file to FileStorage", e);
            }

            filesDc.getMutableItems()
                    .add(dataManager.commit(fd));
        }

        notifications.create(Notifications.NotificationType.TRAY)
                .withCaption("Файлы загружены: " + multiUploadField.getUploadsMap().values())
                .show();
    }

и получаю вот такую ошибку:

строка с ошибкой fileUploadingAPI.putFileIntoStorage(fileId, fd);
что я делаю не так?

Не могли бы вы прислать тестовый проект, на котором воспроизводится проблема?

test327594 · 22.07.2019 06:29:24

MUpload.zip (115.8 КБ)
Алгоритм:
Upload выбираем файлы - загружаем, все хорошо, файлы появились в списке.
Upload выбираем файлы - загружаем, получаем ошибку.

Спасибо за предоставленный проект. Воспроизвести ошибку удалось.

Создал тикет по проблеме: GitHub

tsarev · 28.07.2019 23:11:05

Проблема возникала из-за неправильного использования компонента. После каждой загрузки файлов необходим вызов multiUploadField.clearUploads()

test327594 · 28.07.2019 23:53:46

Подскажите как лучше для обновления источника вызывать загрузчик с параметрами?
так:

expertiseCustomerIIBuildersDl.setParameter("expertiseID", getEditedEntity());
expertiseCustomerIIBuildersDl.load();

или так:

getScreenData().getLoader("loaderId").load();

tsarev · 29.07.2019 07:28:23

Первый вариант. Во втором параметры вообще не проставляются ведь.
