Forms, lists, and search views are defined using the arch XML structures. To extend views, we need a way to modify this XML. This means locating XML elements and then introducing modifications at those points.
Inherited views allow just that. An inherited view declaration looks like this:
<record id="view_form_todo_task_inherited"
model="ir.ui.view">
<field name="name">Todo Task form - User
extension</field>
<field name="model">todo.task</field>
<field name="inherit_id"
ref="todo_app.view_form_todo_task"/>
<field name="arch" type="xml">
<!-- ...match and extend elements here! ... -->
</field
</record>
The inherit_id field identifies the view to be extended by referring to its external identifier using the special ref attribute. External identifiers will be discussed in more detail in
