Greetings,

Am trying to create a module that add some fields to product module .

i did the structure very well which i create "__init__.py , __openerp__.py , product_rolls_code.py , product_rolls_code_view.xml " .

the problem is i can't see my field .

Check out my code bellow

__ init__.py

import product_rolls_code

__ openerp__.py

{
'name': "Product Rolls",
'version': "1.0",
'category': "others",
'complexity': "normal",
'author': "Moayad Rayyan",
'depends': [
    "product" #name of module which is needed to be installed
],
'init_xml': [
    #place here the XML with initial data
],
'update_xml': [
    "product_rolls_code_view.xml",
],
'data': ['product_rolls_code_view.xml'],
'demo_xml': [],
'test': [],
'installable': True,
'auto_install': False,
'application': False,
'images': [],
'js': [], }

product_rolls_code.py

from openerp.osv import fields, osv

class product_rolls_code(osv.osv):

_inherit = "product.product"

_columns = {
    'product_rolls': fields.char('Product Rolls', size=11),
}
product_rolls_code()

product_rolls_code_view.xml

<?xml version="1.0" encoding="utf-8"?>
<openerp>
<data>    
    <record id="product_rolls_product" model="ir.ui.view">
        <field name="name">product.product.form</field>
        <field name="model">product.product</field>
        <field name="inherit_id" ref="product.product_template_only_form_view"/>
