Question

所以我有3个类别。首先是没有孩子，第二是总是有孩子，但有时没有父母，有时第三类总是没有父母。

我的目标是从下到上遍历这3个类别。

首先，我需要检查没有孩子的类别，其次是secodn类别，然后是第三。

如果满足我的条件，我只是显示消息，如果不符合条件，我转到另一个类别并检查条件。

所以我写了这段代码，还可以，但是也许我可以不用重复自己就可以做，并使我的代码更简单？

 msg = _("some %s %s message: %s.")
    msgs = []
for line in order.order_line:
    parent_id = line.product_id.categ_id.parent_id
    parent_parent = line.product_id.categ_id.parent_id
    categ_id = line.product_id.categ_id
    categorys = parent_id + parent_parent + categ_id
categorys = parent_id + parent_parent + categ_id
for categ in categorys:
    if not categ.childs_id and categ.qty_for_discount:
        if line.product_qty < categ.qty_for_discount:
            msgs.append(
                msg % (
                    categ.qty_for_discount - line.product_qty,
                    line.product_id.uom_id.name,
                    categ.name
                )
            )
    elif categ.parent_id and categ.child_id and categ.qty_for_discount:
        if line.product_qty < categ.qty_for_discount:
            msgs.append(
                msg % (
                    categ.qty_for_discount - line.product_qty,
                    line.product_id.uom_id.name,
                    categ.name
                )
            )
    else:
        if line.product_qty < categ.qty_for_discount:
            msgs.append(
                msg % (
                    categ.qty_for_discount - line.product_qty,
                    line.product_id.uom_id.name,
                    categ.name
                )
            )

利用Python的可变范围。尝试这样的事情：

def your_method(self):
    msgs = []
    def append_msg():
        msgs.append( _("some %s %s message: %s.")% (
            categ.qty_for_discount - line.product_qty,
            line.product_id.uom_id.name,
            categ.name
        ))
    for line in order.order_line:
        parent_id = line.product_id.categ_id.parent_id
        parent_parent = line.product_id.categ_id.parent_id
        categ_id = line.product_id.categ_id
        categories = parent_id + parent_parent + categ_id
        categories = parent_id + parent_parent + categ_id
        for categ in categories:
            if not categ.childs_id and categ.qty_for_discount:
                if line.product_qty < categ.qty_for_discount:
                    append_msg()
            elif categ.parent_id and categ.child_id and categ.qty_for_discount:
                if line.product_qty < categ.qty_for_discount:
                    append_msg()
            else:
                if line.product_qty < categ.qty_for_discount:
                    append_msg()
