Inheritance | Traditional Class Inheritance in Odoo 16
● Inheritance means we are going to use or inherit old class/model, properties, methods, and views in the new class/model. This concept is related to Object Oriented Programming. In Odoo/ERP we extend properties, fields, and views of an existing model in a modular way. Here we are going to learn about traditional class inheritance. This is used to extend the features of an existing object.
• For inheriting existing class we use the keyword ‘_inherit’ . That is, _inherit = model name , and here this is python file named as ‘sale_order.py’
• This is an existing model, which is ‘sale.order’ and into this model we have inherited to a new class and used the inherited keyword inherit the existing model and also define a new field here ‘is_version’ , So that, this field will be added into the database or the table of this existing model.
• Now , we have to inherit this field in the views. The view file is look like below,
• Put the name as ‘sale_order_view.xml’ in the view file; also add this view in the ‘__manifest__.py’ file.
