Hola a todos
Estoy haciendo un nuevo modulo el cuál necesito heredar la linía de venta
del módulo ventas. El tipo de herencia que necesito es una herencia que
permita heredar todo lo necesario pero que sea independiente del modelo de
ventas (que pueda manpular el modulo heredado pero sin modificar el
original) El código del archivo .py és:
from trytond.model import ModelView, ModelSQL, fields
from trytond.pyson import Eval
from trytond.transaction import Transaction
from trytond.pool import Pool
class Sale (ModelView, ModelSQL):
'Sale'
_name = 'pos.sale'
_description = __doc__
_inherits = {'sale.sale': 'sale'}
Sale()
la parte del archivo xml donde hace referencia a la herencia és:
<record model="ir.ui.view" id="sale_tree">
<field name="model">sale.sale</field>
<field name="type">tree</field>
<field name="inherits" ref="sale.sale_view_tree"/>
<field name="arch" type="xml">
<![CDATA[
<data>
<xpath
expr="/tree"
position="replace_attributes">
</xpath>
</data>
]]>
</field>
</record>
<record model="ir.ui.view" id="sale_form">
<field name="model">sale.sale</field>
<field name="type">form</field>
<field name="inherits" ref="sale.sale_view_form"/>
<field name="arch" type="xml">
<![CDATA[
<data>
<xpath
expr="/form"
position="replace_attributes">
<form string="Sales"/>
</xpath>
]]>
</field>
</record>
<record model="ir.action.act_window" id="act_sale">
<field name="name">Sale</field>
<field name="res_model">sale.sale</field>
</record>
y el error és el siguiente:
Traceback (most recent call last):

A que se debe el error? Muchas grácies y disculpar las molestias
