Double generation by a template

Double generation by a template can be used when creating a document in the system.
For example, you use a template for generating a document. At this moment, the document is not registered yet, therefore the registration number is not inserted into the generated file. You need the registration number to be inserted into the file automatically.

This can be implemented using a business process:

Let's take a look at each activity.

1. Select Document activity.

Add a variable of a document type on the Context tab. This variable will store the final document version.

2. Primary Generation by Template activity.

On the Settings tab, add a template and a File type variable, to which the generated document will be saved.

Since the generation is performed in two steps, the template will look like this:
Number{‘{$Document.RegistrationCard[0].RegNumber}’}
The first braces will be expanded at the first generation, and the second - at the second generation.

3. Change Version Script activity.

A script for adding a new version (File context variable) to the document (Document context variable).

Script with PublicAPI

Context variables: 

context.Document - variable of the Document type
context.File - variable of the File type

Namespace:

using EleWise.ELMA.API;

Script text:

var DocVersion = PublicAPI.Docflow.DocumentVersion.AddDocumentVersion(context.Document, context.File,PublicAPI.Enums.Documents.DocumentVersionStatus.Current);
PublicAPI.Docflow.DocumentVersion.RenameVersionFile(DocVersion, "file1.rtf", false);

Script without PublicAPI

For the script to work correctly, add the assemblies:

Elewise.ELMA.Documents;

Elewise.TemplateGenerator.Merged;

Namespaces:

using EleWise.ELMA.Documents.Managers;
using EleWise.ELMA.Runtime.Managers;
using EleWise.ELMA.Services; 
using EleWise.ELMA.Templates;

Script text:

var version = InterfaceActivator.Create<DocumentVersion>();
version.Document = context.Document;
version.File=context.File;
version.Name = "generated version";
version.Status = DocumentVersionStatus.Current;//set the Current status to the version
version.File.Name="file1.rtf";
context.Document.Versions.Add(version);
context.Document.Save(); 

4. Register Document activity.

At this stage, a registration number is created, which will be used in the template.

5. Second Generation by Template activity.

The second generation is performed with a script; also, the document version is changed in this activity. The document, generated during the primary generation is used as a template.

Script with PublicAPI

Namespace:

using EleWise.ELMA.Services;
using EleWise.ELMA.Documents.Managers;
using EleWise.ELMA.Runtime.Managers;
using EleWise.ELMA.API;

Script:

var versionFile = Locator.GetServiceNotNull<IDocumentFileManager>().GetFileByDocumentId(context.Document.Id);
var file = Locator.GetServiceNotNull<ITemplateFileManager>().CreateFromTemplate(versionFile.Id);
// Generate the document
PublicAPI.Services.DocumentGenerator.Generate(file, context);
// Save the generated document file
PublicAPI.Services.File.SaveFile(file);
// Save the result to the variable
var DocVersion = PublicAPI.Docflow.DocumentVersion.AddDocumentVersion(context.Document, file, PublicAPI.Enums.Documents.DocumentVersionStatus.Current);
PublicAPI.Docflow.DocumentVersion.RenameVersionFile(DocVersion, "file2.rtf", false);

Script without PublicAPI

For the script to work correctly, add assemblies:

Elewise.ELMA.Documents; Elewise.TemplateGenerator.Merged;

Namespaces:

using EleWise.ELMA.Documents.Managers;
using EleWise.ELMA.Runtime.Managers;
using EleWise.ELMA.Services; 
using EleWise.ELMA.Templates;

Script text: 

var version = InterfaceActivator.Create<DocumentVersion>();
version.Document = context.Document;
var versionFile = Locator.GetServiceNotNull<IDocumentFileManager>().GetFileByDocumentId(context.Document.Id); 
var file = Locator.GetServiceNotNull<ITemplateFileManager>().CreateFromTemplate(versionFile.Id); 
// Create a generator 
var generator = Locator.GetServiceNotNull<DocumentGeneratorManager>().Create(file.ContentFilePath); 
// Generate a document 
generator.Generate(context); 
// Save the generated file
Locator.GetServiceNotNull<IFileManager>().SaveFile(file); 
// Write the result to a variable 
version.File=file;
version.Name = "generated version";
version.Status = DocumentVersionStatus.Current;//set the Current status to the version
version.File.Name="file2.rtf";
context.Document.Versions.Add(version);
context.Document.Save();

6. Display Document activity.
