How to import excel file by entity via x++

(0) ShareShare
ReportReport
Posted on by 1,979

Hi,

want to create a form with upload button, this upload button should take excel files only. Once uploaded and then when I click ok,  it should take the values and import them to an already existing data project that supports excel and has an entity in it.

What code should I write?

I have the same question (0)

    Here comes my question. Instead of using the some entity the standard functionality, why is it required to divert that by adding a new form with upload button and again going to entity. Instead you can directly go to entity and create an import project and do the import right?

    Hi Baharani,

    I want to do it like that because I want to import vendor catalog and this is how vendor catalog works. But the thing is that vendor catalog only supports xml and I want to it to support excel.

    So in general how can I import the uploaded excel file to an existing data project by code?

    Yes, it can be done.

    You can utilize DMFQuickImportExport::doPGImport(). If you put it to a search engine, you'll fine several examples. Some may also exist in the standard application (you can try "Find references" on doPGImport().

    Hi Martin,

    I'm trying to do similar to what a standard method is doing, but the difference is that the standard one is XML and it's calling these two methods in Order.

    Now since i want Excel,

    For the first method “preProcessCatalogMaintenanceRequestXML”  -- how can i change it to add uploadDateTime field to excel instead of XML?

    For the 2nd method “importCatalogFile” – I think I should leave it as is, except for replacing composite entity (DictCompositeDataEntity ) class and get single entity instead, correct?

    protected void preProcessCatalogMaintenanceRequestXML()
        {
            CatVendorDateTime uploadDateTime = CatVendorCatalogMaintenanceRequest::findRecId(catVendorCatalogMaintenanceRecId).UploadDateTime;
    
            XmlDocument xmlDoc = XMLDocument::newFromStream(fileStream);
    
            XMLElement catalogMaintenanceRequestNode = xmlDoc.documentElement().getNamedElement(tableStr(CatVendorCatalogMaintenanceRequestEntity));
            XMLNode uploadDateTimeNode = xmlDoc.createElement(fieldStr(CatVendorCatalogMaintenanceRequestEntity, UploadDateTime));
           
            if (CatVendorCatalogImportUploadDateTimeFormatFlight::instance().isEnabled())
            {
                uploadDateTimeNode.text(DateTimeUtil::toStr(uploadDateTime));
            }
            else
            {
                uploadDateTimeNode.text(datetime2Str(uploadDateTime));
            }
    
            catalogMaintenanceRequestNode.appendChild(uploadDateTimeNode);
           
            System.IO.MemoryStream outputStream = new System.IO.MemoryStream();
            ClrObject inputArray = System.Text.Encoding::get_UTF8().GetBytes(xmlDoc.InnerXML());
            outputStream.Write(inputArray, 0, inputArray.get_length());
    
            fileId = this.uploadFileToTempStorage(outputStream, fullFileName);
        }
    


     private void importCatalogFile()
        {
            DMFDefinitionGroup  definitionGroup = CatVendorCatalogMaintenance::findVendorCatalogDefinitionGroup();
            DMFExecutionId      executionId     = DMFUtil::setupNewExecution(definitionGroup.DefinitionGroupName);
    
            ttsbegin;
            // Find execution
            DictCompositeDataEntity compositeDataEntity = new DictCompositeDataEntity(this.compositeDataEntityName());
            DMFDefinitionGroupExecution execution =
                        DMFDefinitionGroupExecution::find(definitionGroup.DefinitionGroupName, compositeDataEntity.label(), executionId, true);
            execution.IsTransformed = NoYes::No;
            execution.FilePath = execution.applyTransforms(fileId);
            execution.IsTransformed = NoYes::Yes;
            execution.update();
            ttscommit;
    
            // Import data. Wait for data to be imported
            DMFQuickImportExport::doPGImport(definitionGroup.DefinitionGroupName, executionId);
    
            infolog.clear();
        }

    The question of modifying the Excel file don't belong to this thread (which is about "How to import excel file by entity via x++"). Feel free to create a new thread (with an appropriate title) and explain your requirements there.

    By the way, you're asking here for a long time - you should already know how to use Insert > Code.

    Regarding importCatalogFile(), you definitely need another entity name. Whether  doing such thing make sense in that (unknown) is not something I can evaluate.
