        'code':fields.integer('Unique ID'),
        'sal':fields.float('Salary'),

New module .py file

from osv import osv
from osv import fields
class my_base(osv.osv):
    _name='my.base'
_inherit='test.base'
    _columns={
        'dept':fields.char('Department'),       

        }       
my_base()     

(new field 'dept can be added after 'ded' field also please explain on xml id's)

Answer 1

Here you have inherited the test.base model and its functionality to my.base. So my.base will be considered as a new model and you have define a new view for your my.base model. You cannot inherit the view of test.base. If you are trying to add a new field to the test.base model, then from your my_base() class remove the _name attribute or change the name attribute to _name ='test.base'. Then you can inherit the view of test.base model to add the new field. For example you want to add new field 'dept' to the tree view of test.base, then

<record model="ir.ui.view" id="test_base_tree_inheirt">
    <field name="name">test.base.tree</field>
    <field name="model">test.base</field>
    <field name="type">tree</field>
    <field name="inherit_id" ref="<base_module_name>.test_base_tree"/>
    <field name="arch" type="xml">
        <field name="email" position="after">
            <field name="dept"/>
        </field>
    </field>
</record>

Here base_module_name is the name of the module where the original view with id test_base_tree is defined. If it is in the same module then no need to provide the module name, just the view id. In this way you can also inherit the form view.
