We can examine each attribute used for view inheritance:
1. XPath Tag Within the `arch` Field:
`expr="//page[@name='hr_settings']"`: This XPath expression
targets a specific element within the original view.
2. Position:
This attribute determines the placement of the field,
specifying whether it should be added before, after, or replace
the targeted element.

Different types of inheritance in odoo 18
- 1. Different types of inheritance in odoo 18 Enterprise
- 2. Enterprise In Odoo 18, inheritance enables seamless customization of modules, from data models and views to methods and interfaces. This slide outlines the different types of inheritance techniques for extending functionality effectively. Introduction
- 3. Enterprise The two types of inheritance in Odoo are, 1- Model Inheritance 2- View Inheritance Types of Inheritance
- 4. Enterprise Odoo offers three main types of model inheritance: 1) Delegation 2) Extension 3) Classical inheritance. Model Inheritance
- 5. Enterprise
- 6. Enterprise In Odoo, when both the `_inherit` and `_name` attributes are used together, the new model builds upon the existing model specified by `_inherit`. This allows the new model to inherit all the fields, methods, and metadata (such as defaults) from the base model. Classical Inheritance
- 7. Enterprise
- 8. Enterprise In the code above, two classes are defined: a parent class and a child class. The parent class only specifies the `_name` attribute, while the child class defines both `_name` and `_inherit`. This allows the child model to inherit the fields and functions of the parent class. Let’s now see how this works in practice: Explanation
- 9. Enterprise In this way, the child model can access the data, fields, and functions of the parent model.
- 10. Enterprise When using the extension form of inheritance, only the _inherit attribute is needed, without the _name attribute. This replaces the original model with the new one, while allowing us to add more fields or functionalities to the existing model. Below is an example of how to implement extended inheritance: Extension
- 11. Enterprise
- 12. Enterprise When we inspect the database, we can see that the field `description` has been added to the model `extension.extension`. We use the _inherits attribute for delegation inheritance. This type of inheritance allows you to link another model to your current model without altering the views. As a result, the database tables will contain both a field for the inherited object and the data from your model. Below is an example of how to implement delegation inheritance: Delegation
- 13. Enterprise
- 14. Enterprise In Odoo, we can observe that the product template contains several `many2one` fields in the product model. Odoo provides multiple examples of this setup. These fields are stored exclusively in the product template table, although the product model can access and use the fields from the product template. Delegation
- 15. Enterprise ● View inheritance in Odoo lets child views extend base views without replacing them. Using inherit_id, extension views can add or remove elements via XPath components in the arch field. ● In other words, these extensions allow you to add or remove elements from the parent view View Inheritance
