未找到Odoo字段

我正在使用Odoo 8，並且由於某種原因找不到實際存在的字段。在我的XML文件中的以下代碼未找到Odoo字段

  <field name="amount_tax" position="after"> 
       <field name="delivery_cost" 
        options="{'currency_field': 'currency_id'}" 
        readonly="1" widget="monetary"/> 
      </field>

給出了「delivery_cost」未發現錯誤，雖然在sale.py存在

_columns = { 
    'xx_delivery_date': fields.date(string='Delivery date'), 
    'xx_payment_method': fields.many2one('xx.payment.method', 
             string='Payment method'), 
    'xx_warranty_period': fields.many2one('xx.warranty.period', 
              string='Warranty period'), 
    'xx_delivery_method': fields.many2one('xx.delivery.method', 
              string='Delivery method'), 
    'delivery_cost': fields.function(_amount_all_wrapper, digits_compute=dp.get_precision('Account'), string='Delivery cost', 
     store={ 
      'sale.order': (lambda self, cr, uid, ids, c={}: ids, ['order_line', 'xx_delivery_method'], 10), 
     }, 
     multi='sums', help="The delivery cost.", track_visibility='always'), 
    'amount_untaxed': fields.function(_amount_all_wrapper, digits_compute=dp.get_precision('Account'), string='Untaxed Amount', 
     store={ 
      'sale.order': (lambda self, cr, uid, ids, c={}: ids, ['order_line'], 10), 
      'sale.order.line': (_get_order, ['price_unit', 'tax_id', 'discount', 'product_uom_qty'], 10), 
     }, 
     multi='sums', help="The amount without tax.", track_visibility='always'), 
    'amount_tax': fields.function(_amount_all_wrapper, digits_compute=dp.get_precision('Account'), string='Taxes', 
     store={ 
      'sale.order': (lambda self, cr, uid, ids, c={}: ids, ['order_line'], 10), 
      'sale.order.line': (_get_order, ['price_unit', 'tax_id', 'discount', 'product_uom_qty'], 10), 
     }, 
     multi='sums', help="The tax amount."), 
    'amount_total': fields.function(_amount_all_wrapper, digits_compute=dp.get_precision('Account'), string='Total', 
     store={ 
      'sale.order': (lambda self, cr, uid, ids, c={}: ids, ['order_line', 'xx_delivery_method'], 10), 
      'sale.order.line': (_get_order, ['price_unit', 'tax_id', 'discount', 'product_uom_qty'], 10), 
     }, 
     multi='sums', help="The total amount.")

我不明白爲什麼這個領域可以」找不到並且一直在尋找相當一段時間：/

你能給我們更多的觀點一樣，完整的XML定義，對象的_name和服務器引發的錯誤信息？ –

您是否在__init__.py文件中添加了py並在重新啓動openerp服務後更新了模塊？ – dccdany

可能是您的模型中存在拼寫錯誤或錯誤。如果出現錯誤，Odoo不會加載你的模型，但不會引發錯誤...順便說一句，你應該使用新的API（models.Model）和新的方式來聲明你的字段 – dturcotte
