As you can see product.template is parent object and product.product_template_only_form_view is parent view. After you know name field, parent object and parent view we can begin with the code.

4. Create Folder and 4 File inside the folder

i just create folder and give name dedy_custom_field, 4 file is __init__.py , __openerp__.py , add_field_product_view.xml , add_field_product.py.

__init__.py 

import add_field_product # Name file py

Its just import file py that your have created.

 __openerp__.py

{
    'name'          : 'Dedy Custom Fields Product',     # Name App
    'version'       : 'v.1.0',                                           # No Version
    'summary'       : 'Dedy Custom Fields Product', # Name Sumary
    'sequence'      : 1,                                                # No App
    'author'        : 'Dedy Yuristiawan',                      # Name Author
    'description'   : """                            
 
                        author : Dedy Y
                     
                        v.1.0 : \n
                        This module for add additional fields in Product\n
                     
         
                      """,                                                # Name description
    'category'      : 'field',                                      # Name category
    'depends'       : ['base','product'],                    # Name point parent
    'data'          : [
                        'add_field_product_view.xml',
                      ],                                                  # Name file xml
    'installable'   : True,                  
    'application'   : True,
    'auto_install'  : False
}

The point from this file is depends (from parent object), data (file xml), and name app.  

add_field_product.py

add_field_product.py

from openerp import tools
from openerp import models, fields, api
from pygments.lexer import _inherit

class AddFieldProduct (models.Model):# Name class
    _inherit = "product.template"    # Name parent object
 
    info = fields.Char('Info')       # Name field want you show to your xml with char type

The point from this file is name parent object and variable field

add_field_product_view.xml

<openerp>
    <data>
   
     <record model="ir.ui.view" id="add_field_product_tree">              
     # For the tree view and id field (whatever)
         <field name="name">add.field.product.tree</field>  
         # Name field (whatever)
         <field name="model">product.template</field>     
         # Parent object
         <field name="inherit_id" ref="product.product_template_tree_view"/>
         # Parent View
         <field name="arch" type="xml">
     <xpath expr="//field[@name='type']" position="after"> 
     # Name field and Position (after)
       <field name="info"/>         
       # Your new Field
             </xpath>
         </field>
     </record>
   
     <record model="ir.ui.view" id="add_field_product_form">    
     # For the tree view and id field (whatever)
      <field name="name">add.field.product.form</field>    
      # Name field (whatever)
      <field name="model">product.template</field>     
      # Parent object
      <field name="inherit_id" ref="product.product_template_only_form_view"/>
      # Parent View
      <field name="arch" type="xml">
      <xpath expr="//field[@name='type']" position="after"> 
  # Name field and Position (after)
        <field name="info"/>         
         # Your new Field
   </xpath>
      </field>
     </record>  
   
    </data>
</openerp>

 The point from this file is name (its whatever), model (from parent object), inherit_id (from parent view), Name field from odoo (@name='type') and name field that you already created.

After you already create 4 file and then put into folder addons odoo.
