如何将文档从 Odoo 中的向导附加到员工？

如何解决如何将文档从 Odoo 中的向导附加到员工？

我扩展了 hr 模块以在“员工”表单中按下“存档”按钮时显示一个向导。该表格旨在向员工添加一些信息，包括一些文件。正如您在下一个代码中看到的，当从向导调用“action_cancel”方法时，“hr.cancelation_wizard”向员工添加“date_cancel”、“reason”和“documents_cancel_ids”（向导表单中的按钮调用该方法） ）。但是当按下该按钮时，它会显示以下错误：

2021-03-10 17:11:15,187 7702 ERROR odoo12 odoo.sql_db: bad query: INSERT INTO "hr_cancel_document" ("id","create_uid","create_date","write_uid","write_date","attachment_id","employee_id","user_id") VALUES (nextval('hr_cancel_document_employee_id_fkey'),2,(Now() at time zone 'UTC'),699,63,2) RETURNING id
ERROR: insert or update on table "hr_cancel_document" violates foreign key constraint "hr_cancel_document_employee_id_fkey"

这是我的代码：
