Odoo form view: Save child in popup window: Javascript trigger SAVE CHILD!

Create an Odoo 15.0 module, e.g. “web_save_child” following OCA guidelines (see link in file). Write javascript to trigger SAVE CHILD! when a user opens a record in form view with a one2many field, opens/creates a child record (opens in a popup window), changes child values and clicks Save in the popup window. (The main record is not saved yet and may be discarded.) Send me the code, let me try it online, or show that it works in a demo video. I will approve. Create an invoice for the project, I need it for accounting purposes. I will pay/confirm in freelancer.com. Make a pull request to [login to view URL] and give me the link. If not “All checks have passed” because the module is not following the OCA conventions, please update the PR until all checks have passed. I will review and approve the PR. --- After posting this project, I will wait 24 hours before I award any proposal. Please propose a realistic price, I will not accept raising the price afterwards. If you have any questions, please use the chat.
