Start import process from any browse screen

I think using the global action logic as-is for Tables, GroupTable etc.. List of actions in CUBA would be a good direction.

A global ImportDataAction like ExcelAction or CreateAction would be the best solution.
Ideally this Action will be easy to implement for component users (devlopers):

<!-- actions -->
<action id="importData" directImport="true" />
...
<!-- buttonsPanel -->
<upload id="importFileUploadBtn" action="mytable.importData" uploadButtonIcon="icons/upload.png"/>

once the file selected and uploaded ...
if directImport == true 
**then** will force the upload process by searching for a configuration inside database related to that entity; auto-selecting one and following the process with the import
**else** will show a popup asking the user to select a configuration or create a new one (similar to step2 & step3 of the Wizard)
**exceptions** : Any exception will throw a message to the user

@mariodavid , Do you know if it's possible to create a global Action, and register it to the app? Exactly the same question asked by : https://www.cuba-platform.com/discuss/t/define-global-table-actions/894

Unfortunately today I have to write the code below on almost all my Browses:

class MyEntityBrowse2 extends EntityCombinedScreen {

    @Inject
    FileUploadField importFileUploadBtn

    @Inject
    FileUploadingAPI fileUploadingAPI

    ImportFileHandler importFileHandler

    ImportFileParser importFileParser

    @Inject
    DataConverterFactory dataConverterFactory

    @Inject
    DataManager dataManager

    @Inject
    GenericDataImporterService genericDataImporterService

    ImportData importData

    @Inject
    Metadata metadata

    @Inject
    Datasource<RouteMgmtType> routeMgmtTypeDs

    @Inject
    GroupDatasource<RouteMgmtType, UUID> routeMgmtTypesDs;

    @Override
    void init(Map<String, Object> params) {


        importFileHandler = new ImportFileHandler(
                importFileUploadBtn: importFileUploadBtn,
                fileUploadingAPI: fileUploadingAPI,
                dataManager: dataManager
        )

        importFileParser = new ImportFileParser(
                importFileHandler: importFileHandler,
                dataConverterFactory: dataConverterFactory
        )

        importFileHandler.onUploadSuccess {

            this.importData = importFileParser.parseFile();


            def iConfig = metadata.create(ImportConfiguration)
            iConfig.dateFormat = 'dd/MM/yyyy'
            iConfig.booleanTrueValue = 'Yes'
            iConfig.booleanFalseValue = 'No'
            iConfig.entityClass = routeMgmtTypeDs.metaClass.name
            iConfig.importAttributeMappers = [new ImportAttributeMapper(
                    configuration: iConfig,
                    entityAttribute: 'objectName',
                    fileColumnNumber: 0,
                    fileColumnAlias: 'objectName'
            )]

            def dataImportResult = genericDataImporterService.doDataImport(iConfig, importData)

            showNotification(String.format("Successfully imported %d records", dataImportResult.entitiesImportSuccess), NotificationType.TRAY_HTML);
            routeMgmtTypesDs.refresh();
        }
        importFileHandler.onUploadError {
            showNotification(formatMessage('fileUploadError'), Frame.NotificationType.ERROR)
        }

    }
}

As far as I know the using the same way the standard actions are defined is not easily possible.

But that does not really matter.
Joerg created this app component in response to this thread you mentioned: https://github.com/balvi/cuba-component-declarative-controllers

Which will solve the problem even more elegant.

Hi @mariodavid,
The component declarative-controllers is really great, but I'm struggling to make it working on the app: https://github.com/genthalili/cuba-component-data-import/tree/with-import-action-on-browser

https://github.com/genthalili/cuba-component-data-import/tree/with-import-action-on-browser/modules/web/src/de/diedavids/cuba/dataimport/web/importable

Do you know why @Component is never detected by cuba ?

[genthalili]

never mind, I found the issue. I see that you already implemented the code, so that's even better
