            raise Warning('Your Document Is Already Expired.')

expiry_date = fields.Date(string='Expiry Date', copy=False)

Answer 1

The issue is this line

expiry_date = fields.Date(string='Expiry Date', copy=False)

In the documentation of the odoo -> field , it requires a date string, what you provided string='Expiry Date' , which is meanless, thus the expiry_date will be assigned a bool which is False , since it is not a valid data string.

You need to change to:

expiry_date = fields.Date(string='2014-06-15', copy=False)

And it should work.

Hope this helps.
