Question

我想在库存移动表单视图中显示所选位置中所选产品的数量。到目前为止，我已经做了很多尝试，但是仍然没有达到预期的结果。

.PY

'is_quant': fields.boolean('Show Quant'),
'show_quant': fields.float(string='Quants Available' , readonly=True),

def onchange_quant(self, cr, uid, ids, is_quant, product_id, location_id, show_quant):

    if is_quant:
        show_quant = self.pool.get('stock.quant').browse(cr, uid, product_id, location_id).qty
        return {'value': {'show_quant': show_quant}}
    else:
        pass

.XML

<field name="is_quant" on_change="onchange_quant(is_quant, product_id, location_id, show_quant)"/>

错误

更新我在下面添加了stock_quant和stock_move类，希望它能阐明我的观点。同样在提出建议后，我通过更改方法进行了更新。
