Question

我需要覆盖sale.py。

中的内置方法_prepare_invoice

但我收到此错误

ValueError: "'builtin_function_or_method' object is not iterable" while evaluating
u'action_invoice_create()'

我需要覆盖方法来创建新发票。

 File "/home/cybrosys/Desktop/odoo-8.0-20150624/addons/Ship/Ship.py", line 104, in _prepare_invoice
    sal_rec = self.browse(cr,uid,id,context=context)
  File "/home/cybrosys/Desktop/odoo-8.0-20150624/openerp/api.py", line 241, in wrapper
    return old_api(self, *args, **kwargs)
  File "/home/cybrosys/Desktop/odoo-8.0-20150624/openerp/models.py", line 5222, in browse
    ids = _normalize_ids(arg)
  File "/home/cybrosys/Desktop/odoo-8.0-20150624/openerp/models.py", line 6090, in _normalize_ids
    return tuple(arg)

以下方法会根据不同的API调用覆盖不同的方式

适用于OpenERP 7.0

from openerp.osv import fields, osv
class sale_order(osv.osv):
    _inherit = 'sale.order'

    def _prepare_invoice(self, cr, uid, order, lines, context=None):
        res=super(sale_order, self)._prepare_invoice(cr, uid, order, lines, context=context)
        res.update({'delivery_note': order.partner_id.picking_warn_msg})
        return res

适用于Odoo 8.0或更高版本

如果您在Odoo中使用新API，则应遵循以下方式

from openerp import models, fields, api, _
class sale_order(models.Model)
   _inherit = 'sale.order'
   @api.v7
   def _prepare_invoice(self, cr, uid, order, lines, context=None):
        res=super(sale_order, self)._prepare_invoice(cr, uid, order, lines, context=context)
        res.update({'delivery_note': order.partner_id.picking_warn_msg})
        return res

我希望我的回答可以帮到你:)。

在sale.py中覆盖_prepare_invoice（self，cr，uid，order，lines，context = None）
