Extending views

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 Chapter 4 , Module Data.

Being XML, the best...
