Inheritance means we are going to use or inherit the 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. In this slide, we are going to learn about traditional class inheritance. This is used to extend the features of an existing object.

2. INTRODUCTION
❖ 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. In this video, we are going to learn about traditional
class inheritance. This is used to extend the features of an existing object.

3. ❖ For inheriting an existing class we use the keyword ‘_inherit’. That is,
➛ _inherit = model name, and here, this python file named as ‘product.py’.

4. ❖ This is an existing model, which is ‘product.product’ 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 ‘product rating’, So that, this field will be added into the database or the table of this
existing model.

5. ❖ Now, we have to inherit this field in the views. The view file is look like the below,

6. ❖ Put the name as ‘product_view.xml’ in the view file; also added this view in the
‘__manifest__.py’ file.

7. ❖ After upgrading the module, Let’s check the field in the ‘product.product’ model. Here you can
see the Field.
