Auto save and create new row in table view

I have created a maintenace screen using a tableview. The customer would like the view to automatically save the record and add a new line once they have populated the last field in the view. Is there a way to do this? Code examples would be appreciated. Thank you in advance.

You need to write your custom model

You could simple use the signals provided by the view and check in the corresponding slot if the last row has been filled out and then just append a row.

What would the code look like to accomplish this?
