I'm generating PDF documents from a docx file, the PDF are contracts to new employees.

In the docx file I have fields like employee's name {{NAME}} and ID {{ID}} and so, from that i can now generate thousands of PDF files.

On the Odoo side, I have Sign Documents Module, it works well.

Browsing in this forum I got the code to upload the document and implement to my need:

attachment_vals = [{
            'res_model': 'sign.template',
            'name': name,
            'type': 'binary',
            'res_id': 4567,
            'mimetype': 'application/pdf',
            'store_fname': name,
            'datas': document_64
        }]
 
        doc_id = self.api.execute_kw(database, uid, api_key, 
                                      "ir.attachment", "create", attachment_vals)

can see the PDF file in the Attachment view page (enabled with developer mode) 

How can I access the document from the Sign module.

Thanks.
