Hello everyone:

I scheduled the next small module Odoo, the files are:

Init conatain:

Import margenes

openerp, contain:

{
    'name': 'Screen Printing',
    'version': '1.0',
    'description': """
    This module adds functionality for
         screen printing companies
    """,
    'author': 'Diogenes Ojeda',
    'depends': ['base','sale'],
    'data': ['vista_margenes.xml'],
    'demo': [],
    'installable': True,
    'auto_install': False,
}

margenes, conatain:

from openerp import models,fields,api

class silkworm_sale_order(models.Model):
    _inherit = 'sale.order'

    _columns = {
        'x_daterequired': fields.date('Date Required'),
        'x_rush': fields.boolean('Rush Order'),
        }

vista_margenes.xml, contain:

<?xml version="1.0" encoding="utf-8"?>

<openerp>
    <data>
       <record id="sale_view_order_form" model="ir.ui.view">
         <field name="model">sale.order</field>
         <field name="inherit_id" ref="sale.view_order_form"/>
         <field name="arch" type="xml">
           <field name="client_order_ref" position="after">
             <field name="x_daterequired"/>
             <field name="x_rush"/>
           </field>
       </record>
    </data>
</openerp>

When I try to install the module, shows me the error below, how could I fix it? Thank You
