in drive Add-On (right sidebar) : Get current folder and selected Files

Question

I'm currently working on a DRIVE Add-on.

I want to add a function to pick a file -> change the name -> move to a selected folder.

Do you know a way to get the current folder and selected files in my Add-on ???

Answer 1

Accessing the current selected item

You can use the manifest to specify the following:

"drive": {
      "homepageTrigger": {
        "runFunction": "onHomePage",
        "enabled": true
      },
      "onItemsSelectedTrigger": {
        "runFunction": "funcname"
      }
    }

The event object passed to the function

function funcname(e) {
   //e contains an event object


Sample Event Object:

{
      "commonEventObject": { ... },
      "drive": {
        "activeCursorItem":{
          "addonHasFileScopePermission": true,
          "id":"0B_xxxxx",
          "iconUrl": "https://drive-thirdparty.googleusercontent.com...",
          "mimeType":"application/pdf",
          "title":"How to get started with Drive"
        },
        "selectedItems": [
          {
            "addonHasFileScopePermission": true,
            "id":"0B_xxxxxx",
            "iconUrl":"https://drive-thirdparty.googleusercontent.com...",
            "mimeType":"application/pdf",
            "title":"How to get started with Drive"
          },
          ...
        ]
      },
      ...
    }

e.selectedItems.id contains the id of the selected item

If a file is selected you can get the id and the file and the parents will provide the current folder. The mimeType can be used to distinguish between files and folders

addon event object

A simple drive addon to provide ids and mimeTypes of selected items

function onHomePage(e) {
  //Logger.log(JSON.stringify(e));
  var cards = [];
  cards.push(displayFileId(e));
  return cards;
}

function displayFileId(e) {
  var card = CardService.newCardBuilder();
  card.setHeader(CardService.newCardHeader().setTitle('File Information'));
  var section = CardService.newCardSection();
  var idtxt = CardService.newTextParagraph().setText('Click on a file to get file id');
  section.addWidget(idtxt);
  card.addSection(section);
  return card.build();
}

function onMyDriveItemSelected(e) {
  var s = '';
  if (e.drive.selectedItems.length > 0) {
    e.drive.selectedItems.forEach(function(itm,i)  {
      if (i > 0) { s += '<br><br>'; }
      s += Utilities.formatString(' %s<br>%s<br> ', itm.id,itm.mimeType);
    });
  }
  var card = CardService.newCardBuilder();
  var section = CardService.newCardSection();
  var infotxt = CardService.newTextParagraph().setText(s);
  section.addWidget(infotxt);
  card.addSection(section);
  return card.build();
}
