Odoo 8 值错误 Picking 模块中的预期单例

Question

Odoo 8 在库存操作中遇到错误，只有当交货单上的 1 行生成超过 1 件相同的商品时。为了转移货物，他们需要被小部件分成两行。分配批次后，打印交货单遇到此错误：

QWebException: ('ValueError', 'Expected singleton: stock.production.lot(4473, 4472)')

需要编辑什么文件（以及如何）来解决这个问题？

Answer 1

循环 move.lot_ids 以获取每个批次名称。

<t t-foreach='move.lot_ids' t-as='lot_id'>
    <span t-field="lot_id.name"/>
</t>

使用CSS样式显示地块名称。
