我需要读取一个对象中的一个字段，也就是purchase.order从另一个对象中读取product.product 这个字段是一个选择类型字段，所以如果这个字段已经si被选中，那么 do _get_product_available_func(('done'))which 是一个已经声明的函数product.product

这是中的选择字段purchase.order

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

这应该是“检索”该字段的功能product.product

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

具有的功能_get_product_available_func(('done))

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',))

所以，我需要_get_product_available_func(('done'))在product.product字段sel_cert中purchase.order的值有值时“执行” si，但给我一个错误，这是 openerp 服务器中的回溯：

Server Traceback (most recent call last):

也许我应该打电话_product_qty_available来代替_get_product_available_func？

任何人都可以澄清这一点？

提前致谢！

尝试这个：

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

更多想法：

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')])
    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'，我们知道故障确实在这个函数的输出中。

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”。
