Hi All, I have a few fields that I need help with.

My Library:
  • Picture (image field)
  • Item Name (text field)
  • Model Nr (text field)
When I export to google drive it creates a spreadsheet and I get 5 fields:
  • Picture (something like file:///storage/emulated/0/memento/files/...jpg)
  • Item Name
  • Model Nr
  • Picture.http (something like,,,,,,)
  • MEMENTO_ID (something like 1544552412839)
Picture.http seems to be a link of the image, but instead of the location on the phone, once it is uploaded to google drive, it is a url of that location.
MEMENTO_ID seems to be a unique id that memento uses, and it seems to be auto incrementing because if I quickly enter data, it is in sequence. But if I wait a while, there is a gap of missing numbers in the sequence. 

I want to use these two fields in my custom scripts that I am creating for my library. Is there any way of retrieving this data? I messed with lib().entries() and entry().field('whatever') without any luck.

The ID is readily available as a property of the Entry object, so entry().id should get you what you want.

As for the URL, you might try an HTTP request. Check out I think an Http object has a get() method that returns an HttpResult object that might contain what you want.

entry().id is something else, not the same "MEMENTO_ID".

Url: How can I know what the URL of the document is in order to use get()?

I would like to ask for a help. 
We need create unique ID based on current date in format YYYYMMDDXXXXXX // let´s say 2024020700001
X represents unique ID with autoincrement ideally if not possible Unique is good for us. 

We have created field "mydate" this one creates automatically with current date but we need to extract the numbers from it. Also we need system to remember last XXXXXX number so it could go on 
We have over 2500 entries created so that´s why we need the date prefix, when we generated Unique ID it´s not really working way we expect. 

we also tried to use but the default memento ID is just too long (it causes problem when we use it in print as barcode)

Purpose of the ID is that we used product serial number, but in most cases it´s missing or cant be read. So we need unique identifier of custom, but we print multiple documents from memento as jasper reports, (A4 & 80 mm thermal paper + labels 5*4CM)

So is need to has some format. Also we collect 5 pages and about 100 inputs in an entry so i´m looking for something elegant best practice would be a hidden JS or combination JS / trigger

Thank you for your help :) Memento is nice system for creating CRM :)

Скрипт Действие в библиотеке.
Поле "mydate" заполняется датой создания записи (свойство entry().creationTime).
ID продукта создается по дате и номеру записи в библиотеке.
Требуется подключение библиотеки moment.min.js 
Заполняются только пустые поля.
Если хотите добавьте проверку на уникальность (обсуждали недавно).

let entries = lib().entries();

let new_id = '';
let p = entries.length;
let i = p;

while (i--) {
  let e = entries[i];
  if (e.field('mydate') === null) {
    e.set('mydate', e.creationTime);
  new_id = e.field('product id');

  if (new_id.length === 0) {
    new_id = moment(e.field('mydate')).format('YYYYMMDDHHmm') + String(p - i).padStart(5,'0');
    e.set('product id', new_id);

Если я правильно понял, Вы хотите оставить некоторые поля с ID пустыми, но скрипт это не позволяет.
Добавьте новое поле логическое (флажок) "Do not change the ID" и внесите изменение в скрипт:

замените строку:

if (new_id.length === 0 && ) {


if (new_id.length === 0 && !e.field('Do not change the ID')) {
// не пропустите "!" - это оператор "НЕ"

Пустые ID не будут заполняться при включённом флажке.
