Hello,

Please specify if you have checked the available basic functionality meant for processing files within business processes - the "Process File" element? If so, could you describe why exactly does this option not work for you?

https://academy.creatio.com/docs/8.x/no-code-customization/bpm-tools/pr…

Hi,

Yes, starting from version 8.x, Creatio uses dependency injection (DI) more actively, including for services like IFileRepository, which is now resolved via ClassFactory.Get<IFileRepository>().

To override the default implementation, you can register your custom class as the default for the interface in the dependency container.
 

Solution: Register your class for the interface

You have to create your own AppEventListener and bind your class to the appropriate interface there.

public class UsrAppEventListener : AppEventListenerBase
{
	public override void OnAppStart(AppEventContext context) 	{
		base.OnAppStart(context);
		ClassFactory.Bind<IFileRepository, CustomFileRepository>(reuseType: ReuseType.Singleton);
    }
}

Where:

• CustomFileRepository is your custom class that implements IFileRepository
• ReuseType.Singleton (or None) depends on your usage

⚠️ Important: Ensure your class fully implements the IFileRepository interface.

This way, when FileService calls ClassFactory.Get<IFileRepository>(), it will receive your custom implementation.

Hi Irina.
I finally manage to upgrate creatio properly so i can try your sollution.
write now i gut such error

Terrasoft.Core.InstanceActivationException
 HResult=0x80131600
 Message=Error creating an instance of the "Terrasoft.Configuration.IFileRepository" class
 Source=<Cannot evaluate the exception source>
 StackTrace:
<Cannot evaluate the exception stack trace>

 This exception was originally thrown at this call stack:
   [External Code]

Inner Exception 1:
ActivationException: Error activating IFileRepository
More than one matching bindings are available.
Matching bindings:
 1) binding from IFileRepository to FileRepository
 2) binding from IFileRepository to UsrFileRepository
Activation path:
 1) Request for IFileRepository

Suggestions:
 1) Ensure that you have defined a binding for IFileRepository only once.

My class is describe like that

    [Terrasoft.Core.Factories.Override]
   public class UsrFileRepository : FileRepository.

can you give me a hand :)

Hi Iryna;
I find solution
I used rebind except bind.
thank you for help

Hello, 

The "Implementing a custom file storage" documentation you referenced utlines how to achieve this, and it does indeed allow you to change the location where files are stored. 

The process involves implementing a custom file storage system using file management API. Specifically, you can:

This interface defines how file content is stored and retrieved. By creating a custom class that implements this interface, you can direct to save files to a file system instead of the database. For example, you could write a class that saves files to a specified directory on the server’s file system.
 

After implementing the storage logic, you register it in SysFileContentStorage lookup, which tells the system to use your custom storage for file operations.

How to check:

You’ll also need a custom file locator (implementing IFileLocator) to specify where files are stored in the file system, and optionally a custom metadata storage (implementing IFileMetadataStorage) if you need to tweak how metadata is handled. 

Our documentation explains more about it:

Not sure if I completely understand, however, if you're wanting to generate a printable and attach to a record, you can do this with a process using the Process File element. This allows you to generate a printable and you can easily attach to a record's files. Then, just wire up the button to run the process. 

Ryan

Ryan Farley,

Thanks, Ryan. That's what I did. I wrote a business process for generating different reports depending on the value of the reference field and adding them to the attached files. In the module, I added a button to call this business process with the transfer of the necessary parameters to it.

Something like this should work:

var base64FileString = Get<string>("Base64File");
var accountId = Get<Guid>("AccountId");
 
var attachFileType = new Guid("529bc2f8-0ee0-df11-971b-001d60e938c6");
var fileName = "SomeFile.docx" // set proper file type in file name
 
var entity = UserConnection.EntitySchemaManager.GetInstanceByName("AccountFile");
var fileEntity = entity.CreateEntity(UserConnection);
fileEntity.SetDefColumnValues();
fileEntity.SetColumnValue("AccountId", accountId);
fileEntity.SetColumnValue("TypeId", attachFileType);
fileEntity.SetColumnValue("Name",fileName);
fileEntity.SetBytesValue("Data", Convert.FromBase64String(base64FileString));
fileEntity.Save();

Ryan

Ryan Farley,

Thank you very much 

Good day,

Based on the screenshots, an empty value appears to be passed to a method with the “service” argument. Unfortunately, there's not enough information available to pinpoint the exact cause of the error at this time.
 

To further investigate, it would be necessary to debug and examine what the service returns in the browser console, identify what service it is, and review the function call stack.
 

These issues typically fall under the scope of a development consultation for a deeper investigation. 

If needed, you may want to discuss this with your manager to arrange a consultation.

Thank you!

The reason why this isn't working is because FileService/GetFile requires authentication to read. This is not an anonymous endpoint. The receiver of this, where ever you're sending this URL of the document to, is actually getting a 401 Unauthorized. 

You'd have to either go the route of sending the base64 of the file, or expose an anonymous service in Creatio to provide the file to the other service.

Ryan

Ryan Farley,

Thank you, can you explain me please how can I convert the file to base64 please, I had see some examples but I not sure if I can do it using a script task in a business process or a source code 

Laura Jurado,

The code would look something like this (not tested, but this should get you started). For this, I have two process params, one a uniqueidentifier AccountFileId (an Id of an account file) and second an unlimited text AccountFileBase64. The script task would look something like this:

var fileId = Get<Guid>("AccountFileId");
 
var entity = UserConnection.EntitySchemaManager.GetInstanceByName("AccountFile").CreateEntity(UserConnection);
if (entity.FetchFromDB(fileId))
{
    var base64FileData = Convert.ToBase64String(entity.GetBytesValue("Data"));
    Set("AccountFileBase64", base64FileData);
}

Ryan

Ryan Farley,

Thank you very much. It helped me a lot 

Hello,
 

The logic of the Version column value for the file object is located at the event level of the "File" object process as part of the CrtCoreBase package.



You can use development to create a replacement for the object, where you use your own custom logic to assign a value to the Version column when the object event occurs. This implementation requires knowledge of development and writing source code.
You can learn more about events in the system on Creatio Academy.

You can also create a business process (no-code) that will make the necessary changes to the column values when adding/modifying a record.
 

Thank you.

Hello Javier,

Regarding the general function of OData, you can find detailed information in the following resource:

OData Overview

For more specific examples and methods, you can refer to this documentation:

OData Methods and Examples

API for file management

Hello,

The data type "File" doesn't mean to be displayed on the page and therefore you cannot upload files to it using the UI.

If you want to work with files, please use the Attachment detail.

Dmytro Vovchenko,

Is it a datatype not meant to be use in Schema/Object level?

Solem Khan Abdusalam,

Hi,

Please use a standard and working approach with the "Attachments and notes" detail on the page to upload files. There is no particular documentation or example on how to add DataValueType.BLOB fields on the page, but you can review how the column is added to the system setting with "MenuLogoImage" code page:

and implement the same.

Oleg Drobina,

That's actually a very cool way to start somewhere!

I'll check it out.



I'll post the sample code after making it work.
