Answer 1

You problem is only because you create a date field and pass a date and time value.

To solve you problem only need remplace datetime.now() by date.today().

IMPORTANT!

You must import date from datetime

from datetime import date

MORE INFORMATION

For your information Odoo have two types of value for date

fields.Datetime()

And

fields.Date()

To help with date, Odoo create two variables to format date and datetime easier. Because date and datetime format could be different between two countries.

When you work on date with datetime.strftime. Never used own formatting but used DEFAULT_SERVER_DATETIME_FORMAT, DEFAULT_SERVER_DATE_FORMAT

from odoo.tools import DEFAULT_SERVER_DATETIME_FORMAT, DEFAULT_SERVER_DATE_FORMAT
