Signing a document version in a script

Consider a script which allows signing the current document version.

Script with PublicAPI

Note
Documentation on PublicAPI is available here
Attention
The script below is relevant for ELMA up to 3.12.1 inclusive.

Context variables:

context.Director - variable of the User type
context.Document - variable of the Document type

Namespace:

using EleWise.ELMA.API;
using EleWise.ELMA.Services;
using EleWise.ELMA.Documents.Managers;
Script text
var manager = Locator.GetServiceNotNull<DocumentVersionExtManager>();
var vers = PublicAPI.Docflow.DocumentVersion.Filter().Document(context.Dokument).Status(PublicAPI.Enums.Documents.DocumentVersionStatus.Current).Find().FirstOrDefault(); // get the current document version
if (vers != null)
{
    var user = PublicAPI.Docflow.Objects.DocumentAssignUser.Create();
    user.User = context. Direktor;
    user.DocumentVersion = vers;
    vers.SignedUsers.Add(user);
    manager.UpdateSimpleDigitalSignature(user);
}

Script without PublicAPI

Context variables are used in the script:
context.Document - variable of the Contract (document type) type
context.Director - variable of the User type

For the script to work, add the following assemblies:

Elewise.ELMA.Documents
Elewise.ELMA.Documents.Docflow

Namespaces:

using EleWise.ELMA.Documents.Managers;
using EleWise.ELMA.Documents.Models;
using EleWise.ELMA.Services;
Script text:
var vers = DocumentVersionManager.Instance.Get(context.Dokument.Id).ToList().Find(v => v.Status == DocumentVersionStatus.Current); //get the current document version
var manager = Locator.GetServiceNotNull<DocumentVersionExtManager>();
if (vers != null)
{
    var v_sign = DocumentVersionExtManager.Instance.Load(vers.Id);
    var user = DocumentAssignUserManager.Instance.Create();
    user.User = context.Direktor;//specify the signatory user
    user.DocumentVersion = vers;
    v_sign.SignedUsers.Add(user); //add the users who signed the document to the list
    manager.UpdateSimpleDigitalSignature(user);//update the digital signature information
}
