Question

我需要从另一个对象purchase.order中读取对象中的字段product.product 此字段是一个选择类型字段，因此如果此字段已选中si，则执行_get_product_available_func(('done'))，这是product.product

中已声明的函数

这是purchase.order

中的选择字段

'sel_cert' : fields.selection([('si', 'Si'),('no','No')], 'Origen Certificado'),

这个函数应该从product.product

“检索”该字段

def desc_cert(self, cr, uid, ids, field_name, field_args, context=None):
    obj = self.pool.get('purchase.order')
    pids = obj.search(cr, uid, [('sel_cert', '=', 'si')])
    val = self._get_product_available_func(('done'))
    if pids == 'si':
            return val

具有_get_product_available_func(('done))

的功能

def _get_product_available_func(states, what):
    def _product_available(self, cr, uid, ids, name, arg, context=None):
        return {}.fromkeys(ids, 0.0)
    return _product_available

_product_qty_available = _get_product_available_func(('done',), ('in', 'out'))
_product_certificado_qty = _get_product_available_func(('done',), ('in', 'out'))
_product_virtual_available = _get_product_available_func(('confirmed','waiting','assigned','done'), ('in', 'out'))
_product_outgoing_qty = _get_product_available_func(('confirmed','waiting','assigned'), ('out',))
_product_incoming_qty = _get_product_available_func(('confirmed','waiting','assigned'), ('in',))

因此，当_get_product_available_func(('done'))中的字段product.product的值为sel_cert时，我需要在purchase.order中“执行”si，但是却给了我一个错误，这是openerp服务器中的回溯：

也许我应该在_product_qty_available中致电_get_product_available_func？

任何人都可以澄清一下吗？

提前致谢！

Answer 1

试试这个：

def desc_cert(self, cr, uid, ids, field_name, field_args, context=None):
    obj = self.pool.get('purchase.order')
    pids = obj.search(cr, uid, [('sel_cert', '=', 'si')])
    if pids == 'si':
        val = self._get_product_available_func(('done'))
        return val

或者这个：

def desc_cert(self, cr, uid, ids, field_name, field_args, context=None):
    if self.pool:
        obj = self.pool.get('purchase.order')
    pids = obj.search(cr, uid, [('sel_cert', '=', 'si')])
    val = self._get_product_available_func(('done'))
    if pids == 'si':
            return val

Answer 2

更多想法：

尝试一次：

def desc_cert(self, cr, uid, ids, field_name, field_args, context=None):
    obj = self.pool.get('purchase.order')
    pids = obj.search(cr, uid, [('sel_cert', '=', 'si')])
    val = self._get_product_available_func(('done'))
    if pids == 'si':
            return val
    return 10

如果我们得到一个AttributeError: 'int' object has no attribute 'get'，我们就知道这个函数的输出确实存在错误。

另一个想法：

def desc_cert(self, cr, uid, ids, field_name, field_args, context=None):
    obj = self.pool.get('purchase.order')
    pids = obj.search(cr, uid, [('sel_cert', '=', 'si')])
    val = self._get_product_available_func(('done'))
    if pids.lower() == 'si':
            return val

现在pids可能是“si”或“Si”。
