Multi level view inheritance

on 10/18/14, 7:33 AM 1,801 views

Is multi level inheritance of views possible in odoo. e.g.

I have inherited the product template to add "my product type" to all products

class my_products(osv.osv):
    _name = "product.template"
    _columns = {
        'my_product_type': fields.char('My Product Type', size=50, required=True),

I have also inherited the view as follows 

        <record model="ir.ui.view" id="product_template_form_view">
            <field name="name">My Products</field>
            <field name="model">product.template</field>
            <field name="inherit_id" ref="product.product_template_form_view"/>
            <field name="arch" type="xml">
          <notebook position="inside">
        <page string="My Product Details">
            <field name="my_product_type"/>

This works if i go to product create forms. 

However if now i go to create the next level of inheritance by creating a book

class book(osv.osv):
    _name = "book"
    _columns = {
        'isbn': fields.char('ISBN', size=30),

and then try to inherit from the form added already for my products

        <record model="ir.ui.view" id="view_books_form">
            <field name="name">Books</field>
            <field name="model">book</field>
            <field name="inherit_id" ref="my_products.product_template_form_view"/>
            <field name="arch" type="xml">
          <notebook position="inside">
        <page string="Book Details">
            <field name="isbn"/>


It does not work. None of the two tabs are displayed. If however i do not inherit from my_products.template form but directly from product.template form. The book details tab is added but not the product details. Does multi level inheritance work in this way

Tel me something, when you inherited product_template in "book" module, for which you given "name" signifying it as an new object.. So the model "book" is a derived object from product_template, and will be treated as a new model...

Hence you need to create new XML views for the object "book", in this case you cannot inherit from its super object view..

Your second case of inherting [book] is obsolutely wrong, You got to understand the behaviour of inheritance... only then you will have a better insight of it...

In Openerp: there are 2 kinds of Inheritance:
  1. Object Inheritance - _inherit
  2. Inheritance by Delegation - _inherits

Do Refer those docs for better info...
