When defining a model that extends another model, it is often necessary to customize the behavior of some methods defined on the original model. This is a very easy task in Odoo, and one of the most powerful features of the underlying framework.
We will demonstrate this by extending a method that creates records to add a new field in the created records.
If you want to follow the recipe, make sure you have the my_module

. In this module, extend the library.book.loan
model as follows:
class LibraryBookLoan(models.Model): _inherit = 'library.book.loan' expected_return_date = fields.Date('Due for', required=True)
Extend the library.member
model as follows:
