Aikau form to upload content with metadata

[mocaruru]

Hi,

I would like to create a Aikau form that can upload a content with some metadata. When I tried to modify simple-page.get.js provided by alfresco sdk 3.0 like below,

var site = page.url.templateArgs.site;
var alfDestination = null;
var result = remote.call("slingshot/doclib/container/" + site + "/documentLibrary");
if(result.status.code == status.STATUS_OK){
   alfDestination = JSON.parse(result).container.nodeRef;

}

var formWidgets = [
{
   name: "alfresco/forms/controls/DojoValidationTextBox",
   config: {
      label: "Document No",
      name: "prop_xyz_docNo"
   }
},
{
   name: "alfresco/forms/controls/DojoValidationTextBox",
   config: {
      label: "Mandatory",
      name: "prop_xyz_mandatory"
   }
},
{
   name: "alfresco/forms/controls/DojoValidationTextBox",
   config: {
      label: "Action",
      name: "prop_xyz_action"
   }
},
{
   id : "FILE_SELECT",
   name: "alfresco/forms/controls/FileSelect",
   config:{
      label: "Upload File...",
      name: "uploadFile"
   }
}
];

//Create the form here
var form = {
   name: "alfresco/forms/Form",
   config: {
      showOkButton: true,
      okButtonLabel: "Save",
      showCancelButton: true,
      cancelButtonLabel: "Cancel",

      okButtonPublishTopic: "ALF_CRUD_CREATE",
      okButtonPublishGlobal: true,
      okButtonPublishPayload: {
         url: "sample/uploadTest",
         //To create the folder under document library, we need the documberLibrary nodeRer,So POST that too.
        alf_destination:alfDestination
},

widgets: formWidgets
}
};

//Add the form and services to the JSON MODEL
model.jsonModel = {
   widgets: [ form ],
   services: [
      "alfresco/services/CrudService",
      "alfresco/services/UploadService",
      "alfresco/services/DialogService",
      "alfresco/services/ActionService",
      "alfresco/services/DocumentService",
      "alfresco/services/SiteService",
      "alfresco/services/NotificationService"
   ]
};

After accessing the page, put the all fields and submit the data, got error in browser console,

Uncaught TypeError: Failed to construct 'File': 2 arguments required, but only 0 present.

I thought I needed to pass some parameter before publishing ALF_CRUD_CREATE but don't know how.

The error message does not point to an error in your JSON - it displays a problem with a core Aikau function (alfresco_core_Core__alfCleanFrameworkAttributes) when used together with native data structures (in this case a File object). It stands to reason thatthe AlfCrudService itself cannot handle form data that includes files. Aikau has a special service for handling file updloads, the UploadService, though that service cannot handle metadata. For your requested interaction it might be necessary to create a composition of the regular Crud and the Upload service, and use a cutom service to handle the pubSub-flow, i.e. by processing the upload first and then immediately post the update of the metadata.

Unfortunately, that is not something you can do by simple configuration in the JSON model - you will have to write Aikau client-side JavaScript for this.

Yoshihiko Aochi‌  I had the same problem I would be grateful if you told me if you have any answer to that
